1 Basic Principles of PLC Ladder Diagram
Foreword: Background and Functions of PLC
PLC (Programmable Logic Controller) is an electronic device, previously called “sequence controller”. In 1978,
NEMA (National Electrical Manufacture Association) in the United States officially named it as “programmable logic
controller”. PLC reads the status of the external input devices, e.g. keypad, sensor, switch and pulses, and execute by
the microprocessor logic, sequential, timing, counting and arithmetic operations according the status of the input
signals as well as the pre-written program stored in the PLC. The generated output signals are sent to output devices
as the switch of a relay, electromagnetic valve, motor drive, control of a machine or operation of a procedure for the
purpose of machine automation or processing procedure. The peripheral devices (e.g. personal computer/handheld
programming panel) can easily edit or modify the program and monitor the device and conduct on-site program
maintenance and adjustment. The widely used language in designing a PLC program is the ladder diagram.
With the development of the electronic technology and wider applications of PLC in the industry, for example in
position control and the network function of PLC, the input/output signals of PLC include DI (digital input), AI (analog
input), PI (pulse input), NI (numeric input), DO (digital output), AO (analog output), and PO (pulse output). Therefore,
PLC will still stand important in the industrial automation field in the future.
1.1 The Working Principles of Ladder Diagram
The ladder diagram was a diagram language for automation developed in the WWII period, which is the oldest
and most widely adopted language in automation. In the initial stage, there were only A (normally open) contact, B
(normally closed) contact, output coil, timer and counter…the sort of basic devices on the ladder diagram (see the
power panel that is still used today). After the invention of programmable logic controllers (PLC), the devices
displayable on the ladder diagram are added with differential contact, latched coil and the application commands
which were not in a traditional power panel, for example the addition, subtraction, multiplication and division
operations.
The working principles of the traditional ladder diagram and PLC ladder diagram are basically the same. The
only difference is that the symbols on the traditional ladder diagram are more similar to its original form, and PLC
ladder diagram adopts the symbols that are easy to recognize and shown on computer or data sheets. In terms of the
logic of the ladder diagram, there are combination logic and sequential logic.
1. Combination Logic
Examples of traditional ladder diagram and PLC ladder diagram for combination logic:

will be open loop (Off), so Y0 will be Off. When X0 is pressed, the contact will be On, so Y0 will be On.
Row 2: Using a normally closed (NC) switch X1 (“B” switch or “B” contact). When X1 is not pressed, the contact
will be On, so Y1 will be On. When X1 is pressed, the contact will be open loop (Off), so Y1 will be Off.
Row 3: The combination logic of more than one input devices. Output Y2 will be On when X2 is not pressed or
X3 and X4 are pressed.
2. Sequential Logic
Sequential logic is a circuit with "draw back” structure, i.e. the output result of the circuit will be drawn back as an
input criterion. Therefore, under the same input criteria, different previous status or action sequence will follow by
different output results.
Examples of traditional ladder diagram and PLC ladder diagram for sequential logic:
Traditional Ladder Diagram PLC Ladder Diagram
Y3
X5
Y3
X6
Y3
X5
Y3
X6
When the circuit is first connected to the power, though X6 is On, X5 is Off, so Y3 will be Off. After X5 is pressed,
Y3 will be On. Once Y3 is On, even X5 is released (Off), Y3 can still keep its action because of the draw back (i.e.
the self-retained circuit). The actions are illustrated in the table below.
Device status
Action sequence X5 X6 Y3
1 No action No action Off
2 Action No action On
3 No action No action On
4 No action Action Off
5 No action No action Off
From the table above, we can see that in different sequence, the same input status can result in different output
results. For example, switch X5 and X6 of action sequence 1 and 3 do not act, but Y3 is Off in sequence 1 and
On in sequence 3. Y3 output status will then be drawn back as input (the so-called “draw back”), making the
circuit being able to perform sequential control, which is the main feature of the ladder diagram circuit. Here we
only explain contact A, contact B and the output coil. Other devices are applicable to the same method. See
Chapter 3 “Basic instructions” for more details.
1.2 Differences Between Traditional Ladder Diagram and PLC Ladder Diagram
Though the principles of traditional ladder diagram and PLC ladder diagram are the same, in fact, PLC adopts
microcomputer to simulate the motions of the traditional ladder diagram, i.e. scan-check status of all the input devices
and output coil and calculate to generate the same output results as those from the traditional ladder diagram based
on the logics of the ladder diagram. Due to that there is only one microcomputer, we can only check the program of
the ladder diagram one by one and calculate the output results according to the program and the I/O status before the
cyclic process of sending the results to the output interface Æ re-reading of the input status Æ calculation Æ output.
The time spent in the cyclic process is called the “scan time” and the time can be longer with the expansion of the
DVP-PLC Application Manual
1-2
1 Basic Principles of PLC Ladder Diagram
program. The scan time can cause delay from the input detection to output response of the PLC. The longer the delay,
the bigger the error is to the control. The control may even be out of control. In this case, you have to choose a PLC
with faster scan speed. Therefore, the scan speed is an important specification requirement in a PLC. Owing to the
advancement in microcomputer and ASIC (IC for special purpose), there has been great improvement in the scan
speed of PLC nowadays. See the figure below for the scan of the PLC ladder diagram program.
The output result is calculated
based on the ladder diagram.
(The result has not yet sent to the
external output point, but the
internal device will perform an
immediate output.)

Besides the difference in the scan time, PLC ladder and traditional ladder diagram also differ in “reverse current”.
For example, in the traditional ladder diagram illustrated below, when X0, X1, X4 and X6 are On and others are Off,
Y0 output on the circuit will be On as the dotted line goes. However, the PLC ladder diagram program is scanned from
up to down and left to right. Under the same input circumstances, the PLC ladder diagram editing tool WPLSoft will be
able to detect the errors occurring in the ladder diagram.

1.3 How to Edit Ladder Diagram
Ladder diagram is a diagram language frequently applied in automation. The ladder diagram is composed of the
symbols of electric control circuit. The completion of the ladder diagram by the ladder diagram editor is the completion
of the PLC program design. The control flow illustrated by diagram makes the flow more straightforward and
DVP-PLC Application Manual 1-3
1 Basic Principles of PLC Ladder Diagram
acceptable for the technicians of who are familiar with the electric control circuit. Many basic symbols and actions in
the ladder diagram come from the frequently-seen electromechanical devices, e.g. buttons, switches, relay, timer and
counter, etc. in the traditional power panel for automation control.
Internal devices in the PLC: The types and quantity of the devices in the PLC vary in different brand names.
Though the internal devices in the PLC adopts the names, e.g. transistor, coil, contact and so on, in the traditional
electric control circuit, these physical devices do not actually exist inside the PLC. There are only the corresponding
basic units (1 bit) inside the memory of the PLC. When the bit is “1”, the coil will be On, and when the bit is “0”, the coil
will be Off. The normally open contact (NO or contact A) directly reads the value of the corresponding bit. The
normally close contact (NC or contact B) reads the opposite state of the value of the corresponding bit. Many relays
will occupy many bits. 8 bits equal a “byte”. 2 bytes construct a “word” and 2 words combined is “double word”. Byte,
word or double words are used when many relays are processed (e.g. addition/subtraction, displacement) at the
same time. The other two devices, timer and counter, in the PLC have coil, timer value and counter value and they
have to process some values in byte, word or double word.
All kinds of internal devices in the value storage area in the PLC occupy their fixed amount of storage units.
When you use these devices, you are actually read the contents stored in the form of bit, byte or word.
Introductions on the basic internal devices in the PLC (See Ch 2. Functions of Devices in DVP-PLC for more details.)
Device Functions
Input relay
The input relay is an internal memory (storage) unit in the PLC corresponding to a external
input point and is used for connecting to the external input switches and receiving external
input signals. The input relay will be driven by the external input signals which make it “0” or
“1". Program designing cannot modify the status of the relay, i.e. it cannot re-write the basic
unit of a relay, nor can it force On/Off of the relay by HPP/WPLSoft.
SA/SX/SC/EH2/SV/EH3/SV2 series MPU can simulate input relay X and force On/Off of the
relay. But the status of the external input points will be updated and disabled, i.e. the external
input signals will not be read into their corresponding memories inside PLC, but only the input
points on the MPU. The input points on the extension modules will still operate normally. There
are no limitations on the times of using contact A and contact B of the input relay. The input
relays without corresponding input signals can only be left unused and cannot be used for
other purposes.
& Device indication: X0, X1,…X7, X10, X11,… are indicated as X and numbered in octal
form. The No. of input points are marked on MPU and extension modules.
Output relay
The output relay is an internal memory (storage) unit in the PLC corresponding to a external
output point and is used for connecting to the external load. The output relay will be driven by
the contact of an input relay, contacts of other internal devices and the contacts on itself. A
normally open contact of the output relay is connected to the external load. Same as the input
contacts, there are no limitations on the times of using other contacts of the output relay. The
output relay without corresponding output signals can only be left unused and can be used as
input relay if necessary.

Device Functions
& Device indication: Y0, Y1,…Y7, Y10, Y11,…are indicated as Y and numbered in octal
form. The No. of output points are marked on MPU and extension modules.
Internal relay
The internal relay does not have connection with the external. It is an auxiliary relay inside the
PLC with the functions same as those of the auxiliary (middle) relay in the electric control
circuit. Every internal relay corresponds to a basic internal storage unit and can be driven by
the contacts of the input relay, contacts of the output relay and the contacts of other internal
devices. There are no limitations on the times of using the contacts of the internal relay and
there will be no output from the internal relay, but from the output point.
& Device indication: M0, M1,…, M4095 are indicated as M and numbered in decimal form.
Step
DVP series PLC offers a step-type control program input method. STL instruction controls the
transfer of step S, which makes it easy for the writing of the control program. If you do not use
any step program in the control program, step S can be used as a internal relay M as well as an
alarm point.
& Device indication: S0, S1,…S1023 are indicated as S and numbered in decimal form.
Timer
The timer is used for timing and has coil, contact and register in it. When the coil is On and the
estimated time is reached, its contact will be enabled (contact A closed, contact B open). Every
timer has its fixed timing period (unit: 1ms/10ms/100ms). Once the coil is Off, the contact iwlwl
be disabled (contact A open, contact B closed) and the present value on the timer will become
“0”.
& Device indication: T0, T1,…,T255 are indicated as T and numbered in decimal form.
Different No. refers to different timing period.
Counter
The counter is used for counting. Before using the counter, you have to give the counter a set
value (i.e. the number of pulses for counting). There are coil, contact and registers in the
counter. When the coil goes from Off to On, the counter will regard it as an input of 1 pulse and
the present value on the counter will plus “1”. We offer 16-bit and 32-bit high-speed counters
for our users.
& Device indication: C0, C1,…,C255 are indicated as C and numbered in decimal form.
Data register
Data processing and value operations always occur when the PLC conducts all kinds of
sequential control, timing and counting. The data register is used for storing the values or all
kinds of parameters. Every register is able to store a word (16-bit binary value). Double words
will occupy 2 adjacent data registers.
& Device indication: D0, D1,…,D11999 are indicated as D and numbered in decimal form.
File register
The file register is used for storing the data or all kinds of parameters when the data registers
required for processing the data and value operations are insufficient. Every file register is able
to store a 16-bit word. Double words will occupy 2 adjacent file registers. In SA/SX/SC series

Device Functions
MPU, there are 1,600 file registers. In EH2/SV/EH3/SV2 series MPU, there are 10,000 file
registers. There is not an actual device No. for a file register. The reading and writing of file
registers should be executed by instructions API 148 MEMR, API 149 MEMW, or through the
peripheral device HPP02 and WPLSoft.
& Device indication: K0 ~ K9,999, numbered in decimal form.
Index register
E and F index registers are 16-bit data registers as other data registers. They can be read and
written and can be used in word devices, bit devices or as a constant for index indication.
& Device indication: E0 ~ E7, F0 ~ F7 are indicated as E and F and numbered in decimal
form.

5. ORB instruction: A block connects to a device or another block in parallel
ORB instruction
If the ANB and ORB operations are with several blocks, the operation should be performed from up to down or
left to right, combining into a block or network.
6. MPS, MRD, MPP instructions: Bifurcation point of multiple outputs, for generating many and diverse outputs.
MPS instruction is the start of the bifurcation point. The bifurcation point is the intersection of the horizontal line
and vertical line. We will have to determine whether to give a contact memory instruction by the contact status of the
same vertical line. Basically, every contact can be given a memory instruction, but considering the convenience of
operating the PLC and the limitation on its capacity, some parts in the ladder diagram will be omitted during the
conversion. We can determine the type of contact memory instruction by the structure of the ladder diagram. MPS is
recognized as “┬” and the instruction can be given continuously for 8 times.
MRD instruction is used for reading the memory of the bifurcation point. Due to that the same vertical line is of
the same logic status, in order to continue analyzing other ladder diagrams, we have to read the status of the original
contact again. MRD is recognized as “├”.
MPP instruction is used for reading the start status of the top bifurcation point and popping it out from the stack.
Since MPP is the last item on the vertical line, the vertical line ends at this point.

MPP is recognized as “└”. Using the method
given above for the analysis cannot be wrong.
However, sometimes the compiling program will ignore
the same output status, as shown in the figure.

7. STL instruction: Used for designing the syntax of the sequential function chart (SFC).
STL instruction allows the program designer a clearer and readable picture of the sequence of the program as
when they draw a sequence chart. From the figure below, we can see clearly the sequence to be planned. When the
step S moves to the next step, the original S will be “Off". Such a sequence can then be converted into a PLC ladder
diagram and called “step ladder diagram”.

1 Basic Principles of PLC Ladder Diagram

See the ladder diagram below. There are 2 ways to indicate the ladder by instruction programs with the same result.

The two instruction programs will be converted into the same ladder diagram. The difference between the ideal
one and less ideal one is the operation done by the MPU. For the ideal way, the combination is done block by block
whereas the less idea way combines all the blocks combine with one another in the last step. Though the length of
the program codes of the two ways are equal, the combination done in the last step (by ANB instruction, but ANB
cannot be used continuously for more than 8 times) will have to store up the previous calculation results in advance.
In our case, there are only two blocks combined and the MPU allows such kind of combination. However, once the
number of blocks exceed the range that the MPU allows, problems will occur. Therefore, the best way is to execute
the block combination instruction after a block is made, which will also make the logic sequence planned by the
programmer more in order.
Example Program 2
See the ladder diagram below. There are 2 ways to indicate the ladder by instruction programs with the same result.

In this example, the program codes and the operation memory in the MPU increase in the less ideal way.
Therefore, it is better that you edit the program following the defined sequence.
Incorrect Ladder Diagram
PLC processes the diagram program from up to down and left to right. Though we can use all kinds of ladder
symbols to combine into various ladder diagrams, when we draw a ladder diagram, we will have to start the diagram
from the left power line and end it at the right power line (In WPLSoft ladder diagram editing area, the right power line
is omitted), from left to right horizontally, one row after another from up to down. See bellows for the frequently seen
incorrect diagrams:

OR operation upward is not allowed.
Reverse flow
“Reverse flow” exists in the signal circuit from the
beginning of input to output.
The up-right corner should output first.
Combining or editing should be done from the
up-left to the bottom-right. The dotted-lined area
should be moved up.
Parallel operation with empty device is not allowed.
Empty device cannot do operations with other
devices.
No device in the middle block.
Devices and blocks in series should be horizontally

1.7 Basic Program Designing Examples
Start, Stop and Latched
In some application occasions, we need to use the transient close/open buttons for the start and stop of an equipment.
To maintain its continuous action, you have to design latched circuits.
Example 1: Stop first latched circuit
When the normally open contact X1 = On and the
normally closed contact X2 = Off, Y1 will be On. If you make
X2 = On at this time, Y1 will be Off. It is the reason why this is
called “stop first”.
X2
Y1
X1
Y1
Example 2: Start first latched circuit
When the normally open contact X1 = On and the
normally closed contact X2 = Off, Y1 will be On and latched. If
you make X2 = On at this time, Y1 will continue to be On
because of the latched contact. It is the reason why this is
called “start first”.

Example 3: Latched circuit for SET and RST instructions
See the diagram in the right hand side for the latched
circuit consist of RST and SET instructions.
X2
Y1
X1
SET
Y1
RST
Stop first
In the stop first diagram, RST is placed after SET. PLC
executes the program from up to down, so the On/Off of Y1 will
be determined upon its status in the end of the program.
Therefore, when X1 and X2 are enabled at the same time, Y1
will be Off. It is the reason why this is called “stop first”.
X2
Y1
X1
SET Y1
RST
Start first
In the start first diagram, SET is placed after RST. When
X1 and X2 are enabled at the same time, Y1 will be On. It is
the reason why this is called “start first”.
Example 4: Power shutdown latched
X2
M512
X1
SET
RST M512
Y1
M512
The auxiliary relay M512 is latched (see instruction
sheets for DVP series PLC MPU). The circuit can not only be
latched when the power is on, but also keep the continuity of
the original control when the power is shut down and switched
on again.

X1 and X3 enables and disables Y1; X2 and X4 enables and disables Y2, and all are latched. Due to that the
normally open contact of Y1 is connected to the circuit of Y2 in series, Y1 becomes an AND condition for Y2.
Therefore, only when Y1 is enabled can Y2 be enabled.

Which of the X1 and X2 is first enabled decides either the corresponding output Y1 or Y2 will be enabled first.
Either Y1 or Y2 will be enabled at a time, i.e. Y1 and Y2 will not be enabled at the same time (the interlock). Even X1
and X2 are enabled at the same time, Y1 and Y2 will not be enabled at the same time due to that the ladder diagram
program is scanned from up to down. In this ladder diagram, Y1 will be enabled first.
Example 7: Sequential control
If we serially connect the normally closed contact
of Y2 in example 5 to the circuit of Y1 as an AND
condition for Y1 (as the diagram in the left hand side),
the circuit can not only make Y1 as the condition for Y2,
but also allow the stop of Y1 after Y2 is enabled.
Therefore, we can make Y1 and Y2 execute exactly the
sequential control.

The ladder diagram above is a very simple one. When the program starts to scan the normally closed contact
Y1, Y1 will be closed because coil Y1 is Off. When the program then scan to coil Y1 and make it On, the output will be
1. When the program scans to the normally closed contact Y1 again in the next scan cycle, because coil Y1 is On, Y1
will be open and make coil Y1 Off and output 0. The repeated scans will result in coil Y1 outputs oscillating pulses by
the cycle ΔT(On)+ΔT(Off).

1 Basic Principles of PLC Ladder Diagram
The rising-edge differential instruction of X0 makes coil M0 generate a single pulse of ΔT (one scan cycle).
Coil Y1 will be On during this scan period. In the next scan period, coil M0 will be Off and the normally closed contact
M0 and Y1 will all be closed, making coil Y1 continue to be On until another rising-edge arrives in input X0, making
coil M0 On for another scan period and Y1 Off. Such kind of circuit relies on an input to make two actions execute
interchangeably. Also from the timing diagram on the last page, we can see that input X0 are square pulse signals of
the cycle T and coil Y1 output are square pulse signals of the cycle 2T.

100 seconds (K1,000 × 0.1 sec = 100 secs) and be Off. See the timing diagram above.

For different control purposes, there are five types of values inside DVP-PLC for executing the operations. See
the explanations bellows for the functions and works of every type of value.
1. Binary value (BIN)
All the operations and storage of values in PLC are conducted in BIN. Belows are the terms for BIN values.
The basic unit for a BIN value, either 1 or 0.
Bit:
Composed of 4 continuous bits (e.g. b3 ~ b0). Presented as the decimal value 0 ~ 9 of a digit
or 0 ~ F in hex.
Nibble:
Composed of 2 continuous nibble (i.e. 8 bits, b7 ~ b0). Presented as 00 ~ FF in hex.
Byte:
Composed of 2 continuous bytes (i.e. 16 bits, b15 ~ b0). Presented as 4-digit 0000 ~ FFFF in
hex.
Word:
Composed of 2 continuous words (i.e. 32 bits, b31 ~ b0). Presented as 8 digit 00000000 ~
FFFFFFFF.

3. Decimal value (DEC)
Occassions of using decimal values in DVP-PLC:
Set value in timer T and counter C, e.g. TMR C0 K50 (constant K)
No. of device S, M, T, C, D, E, F, P, I, e.g. M10, T30. (device No.)
Operands in application instructions, e.g. MOV K123 D0 (constant K)
4. Binary code decimal (BCD)
A decimal datum is presented by a nibble or 4 bits. Therefore, a continuous 16 bits can be presented as a 4-digit
decimal value. BCD is mainly used on reading the input value from the DIP switch or the data output to a 7-section
display.
5. Hexadecimal value (HEX)
Occassion of using hexadecimal values:
Operands in application instructions, e.g. MOV H1A2B D0 (constant H)
Constant K:
“K” is normally placed before a decimal value in the PLC. For example, K100 refers to a decimal value, 100.
Exception:
K and bit devices X, Y, M and S can combine into data in bit, byte, word or double word, e.g. K2Y10, K4M100.
Here K1 refers to a 4-bit data and K2 ~ K4 refer to 8-bit, 12-bit and 16-bit data.
Constant H:
“H” is normally placed before a hexadecimal value in the PLC. For example, H100 refers to a hexadecimal value,
100.

Functions of input contact X
The input contact X is connected to the input device and reads the input signals into the PLC. There is no
DVP-PLC Application Manual 2-11
2 Functions of Devices in DVP-PLC
limitation on the times of using contact A or B of input contact X in the program. On/Off of the input contact X
only changes with On/Off of the input device. You cannot use the peripheral devices (HPP or WPLSoft) to force
On/Off of the input contact X.
The special relay M1304 in SS/ES/EX/SA/SX/SC/EH2/SV/EH3/SV2 series MPU allows the peripheral
devices HPP or WPLSoft to set up On/Off of the MPU input contact X, but the PLC will not be able to receive
external input signals at this time.
Functions of output contact Y
Output contact Y sends out On/Off signals to drive the load connected to output contact Y. There are two
types of output contacts, relay and transistor. Thereis no limitation on the times of using contact A or B of output
contact Y in the program, but the No. of output coil Y can only be used once in the program; otherwise
according to the scan principle of the PLC program, the output status will be determined by the circuit of the last
output Y in the program.
The output of Y0 will be determined by circuit 2, i.e. On/Off of X10 will
determine the output status of Y0.

1. Before the execution of the program, PLC reads the
On/Off status of the external input signals into the
input signal memory at a time.
2. The On/Off status of the input signal during the
execution of the program will not change the signal
status in the input signal memory. The new On/Off
status will be read in in the next scan.
3. There will be approximately a 10ms delay from the
On→Off or Off→On changes to the status being
recognized by the contact in the program. The delay
time may be affected by the scan time in the
program.
Program processing
After the PLC reads the On/Off status of every input
signal in the input signal memory, it will start to execute
every instruction in the program in order starting from
address 0. The execution result (On/Off of every output
coil) will be stored in order into the device memory.

Functions of step relays:
The step relay S can easily set up the procedure in the industrial automation, which is the most basic device in
the the sequential function chart (SFC) and has to be used with STL, RET instructions.

T0 will be On.
When X0 = Off or the power is off, timer T250 will
temporarily stop the timing and the PV remain
unchanged. When X0 is On again, the timing will
resume and the PV will count up and when the PV =
SV K100, the output coil T0 will be On.
3. Subrountine timer:
Timer T192 ~ T199 are used in subrountines or interruption subroutines.
For SA series MPU: The timer executes once when the program reaches END instruction. When END instruction
is executed, the output coil will be On when the timing reaches its target.
For EH2/SV/EH3/SV2 series MPU: The timer executes once when the program reaches TMR or END instruction.
When TMR or END instruction is executed, the output coil will be On when the PV equals SV.
If the general purpose timer is used in a subroutine or interruption subroutine but the subroutine is not being
executed, the timer will not be able to time correctly.
How to designate SV: The actual set time in the timer = timing unit × set value
a) Designating constant K: SV is a constant K
b) Indirectly designating D: SV is data register D

Functions of counters:
When the pulse input signals of the counter go from Off to On and the present value in the counter equals the
set value, the output coil will be On. The set value should be a K value in decimal and the data register D can also be
a set value.
16-bit counters C0 ~ C199:
1. The setup range of 16-bit counter: K0 ~ K32,767. K0 is the same as K1. The output contact will be On
immediately when the first counting starts.
2. PV in the general purpose counter will be cleared when the power of the PLC is switched off. If the counter is a
latched type, the counter will retain the PV and contact status before the power is off and resume the counting
after the power is on again.
3. If you use MOV instruction, WPLSoft or HPP to send a value bigger than the SV to the present value register of
C0, next time when X1 goes from Off to On, the contact of counter C0 will be On and its PV will equal SV.
4. The SV in the counter can be constant K (set up directly) or the values in register D (set up indirectly, excluding
special data registers D1000~ D1999).
5. If you set up a constant K as the SV, it should be a positive value. Data register D as SV can be positive or
negative. When the PV reaches up to 32,767, the next PV will turn to -32,768.

32-bit general purpose addition/subtraction counters C200 ~ C234:
1. The setup range of 32-bit counter: K-2,147,483,648 ~ K2,147,483,647 (not available for ES/EX/SS series MPU).
2. Addition or subtraction of the counters is designated by On/Off status of special auxiliary relays M1200 ~ M1234.
For example, when M1200 = Off, C200 will be an addition counter; when M1200 = On, C200 will be a subtraction
counter.
3. The SV can be constant K or data register D (excluding special data registers D1000 ~ D1999). Data register D as
SV can be a positive or negative value and an SV will occupy two consecutive data registers.
4. PV in the general purpose counter will be cleared when the power of the PLC is switched off. If the counter is a
latched type, the counter will retain the PV and contact status before the power is off and resume the counting
after the power is on again.
5. When the PV reaches up to 2,147,483,647, the next PV will turn to -2,147,483,648. When the PV reaches down to
-2,147,483,648, the next PV will turn to 2,147,483,647.

32-bit high-speed addition/subtraction counters C235 ~ C255:
1. The setup range of 32-bit counter: K-2,147,483,648 ~ K2,147,483,647
2. Addition or subtraction of C235 ~ C244 is designated by On/Off status of special auxiliary relays M1235 ~ M1244.
For example, when M1235 = Off, C235 will be an addition counter; when M1235 = On, C235 will be a subtraction
counter.
3. Addition or subtraction of C246 ~ C255 is designated by On/Off status of special auxiliary relays M1246 ~ M1255.
For example, when M1246 = Off, C246 will be an addition counter; when M1246 = On, C246 will be a subtraction
counter.
4. The SV can be constant K or data register D (excluding special data registers D1000 ~ D1999). Data register D
as SV can be a positive or negative value and an SV will occupy two consecutive data registers.
5. If using DMOV instruction, WPLSoft or HPP to send a value which is large than the setting to any high-speed
counter, next time when the input point X of the counter goes from Off to On, this contact will remain unchanged
and it will perform addition and subtraction with the present value.
6. When the PV reaches up to 2,147,483,647, the next PV will turn to -2,147,483,648. When the PV reaches down

1. The functions of high-speed counters of input points X0 ~ X5 are the same of those in SA/SX series MPU.
2. The maximum frequency of the input points X10 (C243), X11 (C245) and (X10, X11)(C250) of 1-phase input is
100kHz. The total bandwidth of X10 ~ X11 high-speed counting is 130kHz. The maximum input frequency of

3. The use of DHSCS instruction together with DHSCR instruction in SA/SX/SC series MPU cannot exceed 6 times.
The use of DHSZ instruction cannot exceed 6 times as well. When DHSCS instruction designates I interruption,
the designated high-speed counter cannot be used in DHSCS, DHSCR and DHSZ instruction.
4. Functions of high-speed counters X10 ~ X11 in SC series MPU:
a) When X10 and X11 are set to be 1-phase 1 input or 1-phase 2 outputs, the maximum frequency can reach
100kHz. When set to be 2-phase 2 inputs, the maximum frequency can reach 35kHz.
b) X10 and X11 can be set to be rising-edge or falling-edge counting. X10 is set by D1166 and X11 by D1167. K0:
rising-edge counting; K1: falling-edge counting; K2: rising-/falling-edge counting (only available in X10).
c) Counting up or down of C243 is determined by On/Off status of M1243 anc that of C245 is determined by
On/Off of M1245. Rising-edge and falling-edge countings cannot be performed at the same time. Rising edge
or falling edge of C250 is determined by the content (K0 or K1) in D1166. C255 can only be used in 4 times
frequency counting and rising-edge and falling-edge triggers are not available for C255.
d) When you use C243 or C245, you will not be able to use C250 or C255, and vice versa.

f) Explanations on high-speed counter and high-speed comparator:
(i) When DHSCS and DHSCR instructions use new added high-speed counters, they can only use two
groups of SVs in high speed comparison instruction. Assume you have used the comparison instruction
DHSCS D0 C243 Y10, you can only set another group of instruction DHSCR D2 C243 Y10 or DHSCS D4
C245 Y10.
(ii) When DHSZ instruction uses new added high-speed counters, it can only use one group of SV in the
comparator.
(iii) The number of SVs in high speed comparison instructions offered by SA/SX series MPU will not decrease
owing to the increasing of high-speed counters.
(iv) If the output device of the high-speed comparison instruction DHSCS requires high-speed output, it is
recommended you use Y10 or Y11 for the output. If you use other general devices, the output will delay
for 1 scan period for its setup or clearing. For example, if I0x0 interruption is set, C243 will correspond to
I020, C245 to I040, and C250 and C255 to I060.
(v) The high speed comparison instruction DHSCR is able to clear the counter, but only the counters used in

5. Counting modes:
a) The 2-phase 2 inputs counting mode of the high speed counters in ES/EX/SS (V5.5 and versions above) and
SA/SX/SC series MPU is set by special D1022 with normal frequency, double frequency and 4 times

EH2/SV series MPU supports high speed counters. C235 ~ C240 are program-interruption 1-phase high speed
counter with a total bandwidth of 20kHz, can be used alone with a counting frequency of up to 10kHz. EH3/SV2 series
MPU supports high speed counters. C235~C240 are program-interruption 1-phase high speed counter, and can be
used with a counting frequency of up to 10kHz. C241 ~ C254 are hardware high speed counter (HHSC). There are
four HHSC in EH2/SV/EH3/SV2 series MPU, HHSC0 ~ 3. The pulse input frequency of HHSC0 and HHSC1 can
reach 200kHz, and that of HHSC2 and HHSC3 can reach 20kHz (1 phase) or 5kHz (A-B phase). The pulse input
frequency of HHSC0 ~ 3 of 40EH2/40EH3 series MPU can reach 200kHz, among which:
C241, C246 and C251 share HHSC0
C242, C247 and C252 share HHSC1
C243, C248 and C253 share HHSC2

3. System structure of the hardware high speed counters:
a) HHSC0 ~ 3 have reset signals and start signals from external inputs. Settings in M1272, M1274, M1276 and
M1278 are reset signals of HHSC0, HHSC1, HHSC2 and HHSC3. Settings in M1273, M1275, M1277 and
M1279 are start signals of HHSC0, HHSC1, HHSC2 and HHSC3.
b) If the external control signal inputs of R and S are not in use, you can set M1264/M1266/M1268/M1270 and
M1265/M1267/M1269/M1271 as True and disable the input signals. The corresponding external inputs can
be used again as general input points (see the figure below).
c) When special M is used as a high speed counter, the inputs controlled by START and RESET will be affected
by the scan time.

2.8 Numbering and Functions of Registers [D], [E], [F]
2.8.1 Data register [D]
A data register is for storing a 16-bit datum of values between -32,768 to +32,767. The highest bit is “+” or “-"
sign. Two 16-bit registers can be combined into a 32-bit register (D + 1; D of smaller No. is for lower 16 bits). The
highest b it is “+” or “-” sign and it can store a 32-bit datum of values between -2,147,483,648 to +2,147,483,647.
ES/EX/SS series MPU:
General purpose D0 ~ D407, 408 points
Latched D408 ~ D599, 192 points. Fixed to be latched.

File register K0 ~ K9,999, MPU 10,000 points. Fixed to be latched.
There are five types of registers:
1. General purpose register: When PLC goes from RUN to STOP or the power of the PLC is switched off, the data
in the register will be cleared to “0”. When M1033 = On and PLC goes from RUN to STOP, the data will not be
cleared, but will still be cleared to “0” when the power is off.
2. Latched register: When the power of PLC is switched off, the data in the register will not be cleared but will retain
at the value before the power is off. You can use RST or ZRST instruction to clear the data in the latched register.
3. Special purpose register: Every register of this kind has its special definition and purpose, mainly for storing the
system status, error messages and monitored status. See 2.10 and 2.11 for more details.
4. Index register E, F: The index register is a 16-bit register. There are 2 points of E, F in ES/EX/SS series MPU; 8
points (E0 ~ E3, F0 ~ F3) in SA/SX/SC series MPU; 16 points (E0 ~ E7, F0 ~ F7) in EH2/SV/EH3/SV2 series MPU.
If the index register is to be used as a 32-bit register, please designate E. When E is already designated in a
32-bit instruction, using also F will not be allowed.
5. File register: There are 1,600 file registers (K0 ~ K1,599) in SA/SX/SC series MPU and 10,000 file registers (K0
~ K9,999) in EH2/SV/EH3/SV2 series MPU. The file register does not have an exact device No.; therefore the
DVP-PLC Application Manual 2-31
2 Functions of Devices in DVP-PLC
read/write function of file registers has to be executed by instruction API 148 MEMR, API 149 MEMW or through
peripheral devices HPP and WPLSoft.
2.8.2 Index Register [E], [F]
Index registers E, F are 16-bit data registers and can be written and
read.
F0 E0
E0F0
16 bits 16 bits
32 bits
Higher 16 bits Lower 16 bits
If you need to use a 32-bit register, you have to designate E. In this
case, F will be covered by E and cannot be used anymore; otherwise,
the content in E (32-bit) will be incorrect. We suggest you use DMOVP
K0 E instruction, the content in E (including F) will be cleared to “0”
when the power of PLC is switched on.
The combination of E, F when you use a 32-bit index register:
(F0, E0), (F1, E1), (F2, E2), …(F7, E7)
K14 F0
X0
K8 E0MOV
D5E0 D10F0
MOV
MOV
When X0 = On, E0 = 8, F0 = 14, D5E0 = D (5 + 8) = D13, D10F0 = D
(10 + 14) = D24. At this moment, the content in D13 will be moved to
D24.
The index register is the same as normal operands, can be used for moving or comparison on word devicies (KnX,
KnY, KnM, KnS, T, C, D) and bit devices (X, Y, M, S). ES/SA series MPU does not support constant (K, H) index
register, but EH2/SV/EH3/SV2 series MPU supports constant (K, H) index register.
ES/EX/SS series MPU has 2 points of index registers E0, F0
SA/SX/SC series MPU has 8 points of index registers E0 ~ E3, F0 ~ F3
EH2/SV/EH3/SV2 series MPU has 16 points of index registers E0 ~ E7, F0 ~ F7
Some instructions do not support index registers. For how to use index register E, F to modify the operands, see
Chapter 5.4 for more details.
When you use the instruction mode in WPLSoft to generate constant (K, H) index register function, please use
symbol “@”. For example, “MOV K10@E0 D0F0”
When you use index register E, F to modify the operands, the modification range CANNOT exceed the range of
special purpose registers D1000 ~ D1999 and special auxiliary registers M1000 ~ M1999 in case errors may occur.
2.8.3 Functions and Features of File Registers
When the power of PLC is switched on, SA/SX/SC and EH2/SV/EH3/SV2 series MPU will check the following
devices:
1. M1101 (whether the file register is enabled)
2. D1101 (No. of file registers in SA/SX/SC series MPU: K0 ~ K1,599; No. of file registers in EH2/SV/EH3/SV2
series MPU: K0 ~ K9,999)
3. D1102 (Number of file registers to be read in SA/SX/SC series MPU: K0 ~ K1,600; number of file registers to be
DVP-PLC Application Manual
2-32
2 Functions of Devices in DVP-PLC
read in EH2/SV/EH3/SV2 series MPU: K0 ~ K8,000)
4. D1103 (devices for storing the data read from file registers; the No. of designated data register D starts from
K2,000 ~ K9,999; determining whether to automatically send the content in the file register to the designated data
register.)
Note:
1. When D1101 of SA/SX/SC series MPU is bigger than 1,600, D1101 of EH2/SV/EH3/SV2 series MPU is bigger
than 8,000 and D1103 is smaller than 2,000 or bigger than 9,999, the data read from file registers will not be sent
to data register D.
2. When the program starts to send the data read from the file register to data register D and the address of the file
register or the data register D exceed their ranges, PLC will stop the reading.
3. There are 1,600 file registers in SA/SX/SC series MPU and 10,000 in EH2/SV/EH3/SV2 series MPU. The file
register does not have an exact device No.; therefore the read/write function of file registers has to be executed
by instruction API 148 MEMR, API 149 MEMW or through peripheral devices HPP and WPLSoft.
4. If you tend to read a file register with an address that is not within the range, the read value will be “0”.

Interruption Pointer I: Used with API 04 EI, API 05 DI, API 03 IRET. See Chapter 5.5 for more details. There are 6
types of interruption pointer. To insert an interruption, you have to combine the action with EI (enable interruption), DI
(disable interruption), IRET (interruption return) instructions.
External interruption:
1. Due to the special hardware design inside the MPU, the input signals coming in at input
terminals X0 ~ X5 (EH3/SV2: X0~X17) when rising-edge or falling-edge triggers will not be affected by the scan
cycle. The currently executed program will be interrupted immediately and the execution will jump to the
designated interruption subroutine pointer I00□(X0), I10□(X1), I20□(X2), I30□(X3), I40□(X4), I50□(X5). Till
the execution reaches IRET instruction, the program will return to the original position and keep on its execution.
In SA/SX series MPU, X0 (pulse input point) works with X4 (external interruption point), corresponding to C235,
C251 and C253 work with I401, which will be able to interrupt and intercept the present value in the high-speed
counter. D1181 is the device to store the 32-bit value. X1 (pulse input point) works with X5 (external interruption
point), corresponding to C236 works with I501, which will be able to interrupt and intercept the present value in
the high-speed counter. D1198 and D1199 are the devices to store the 32-bit value.
In SC series MPU, X10 (pulse input point) works with X4 (external interruption point), corresponding to C243 and
C255 work with I401, which will be able to interrupt and intercept the present value in the high-speed counter.
D1180 and D1181 are the devices to store the 32-bit value. X11 works with X5, corresponding to C245 works with
I501, which will be able to interrupt and intercept the present value in the high-speed counter. D1198 and D1199
are the devices to store the 32-bit value.
2. Timed interruption: PLC automatically interrupts the currently executed program every a fixed period of time and
DVP-PLC Application Manual 2-35
2 Functions of Devices in DVP-PLC
jumps to the execution of a designated interruption subroutine.
3. Interruption when the counting reaches the target: The high-speed counter comparison instruction API 53
DHSCS can designates that when the comparison reaches the target, the currently executed program will be
interrupted and jump to the designated interruption subrountine executing the interruption pointers I010, I020,
I030, I040, I050 and I060.
4. Pulse interruption: The pulse output instruction API 57 PLSY can be set up that the interruption signal is sent out
synchronously when the first pulse is sent out by enabling flags M1342 and M1343. The corresponding
interruptions are I130 and I140. You can also set up that the interruption signal is sent out after the last pulse is
sent out by enabling flags M1340 and M1341. The corresponding interruptions are I110 and I120.
5. Communication interruption:
I150: When the communication instruction RS is being used, you can send out interruption request when the
program receives a specific word by interruption I150. The specific word is set up in the low byte of D1168. This
function can be adopted when the PLC receives data of different length during the connection with the
communication device. Set up the end word in D1168 and write the interruption subroutine I150 and when the
PLC receives this end word, the program will execute I150.
I160: RS instruction sends out interruption request when receiving a specific length of data. When the data
received equals the low byte of D1169, I160 will be triggered. When D1169 = 0, I160 will not be triggered.
I170: In Slave mode, interruption I170 will be generated when the data receiving is completed. Normally when the
communication terminal of the PLC is in Slave mode, PLC will not immediately process the communication data
entered but process it after the END is executed. Therefore, when the scan time is very long and you need the
communication data to be processed immediately, you can use interruption I170 for this matter.
6. Frequency measurement card triggered interruption:
I180: When the PLC sets up the frequency measurement card in mode 1 (pulse cycle measurement) and mode 3
(pulse number counting) by M1019 and D1034, I180 will be supported as well.

D1000
Number
Contents:
1. Monitor timer is used for moitoring PLC scan time. When the scan time exceeds the set time in the moitor timer,
the red ERROR LED indicator remains beaconing and all outputs will be “Off”.
2. The initial set value of the time in the monitor timer is 200ms. If the program is long or the operation is too
complicated, MOV instruction can be used for changing the set value. See the example below for SV = 300ms.

3. The maximum set value in the monitor timer is 32,767ms. Please be noted that if the SV is too big, the timing of
detecting operational errors will be delayed. Therefore, it is suggested that you remain the scan time of shorter
than 200ms.
4. Complicated instruction operations or too many extension modules being connected to the MPU will result in the
scan time being too long. Check D1010 ~ D1012 to see if the scan time exceeds the SV in D1000. In this case,
besides modifying the SV in D1000, you can also add WDT instruction (API 07) into the PLC program. When the
CPU execution progresses to WDT instruction, the internal monitor timer will be cleared as “0” and the scan time
will not exceed the set value in the monitor timer.

Syntax Check
Function Group
M1004, D1004, D1137
Number
Contents:
1. When errors occur in syntax check, ERROR LED indicator will flash and special relay M1004 = On.
2. Timings for PLC syntax check:
a) When the power goes from “Off” to “On”.
b) When the program is written into PLC by means of WPLSoft, ISPSoft or HPP.
c) When on-line editing is being conducted.
3. The syntax check may start due to illegal use of instruction operands (devices) or incorrect program syntax loop.
The error can be detected by the error code in D1004 and error table. The address where the error exists will be
stored in D1137. (The address value in D1137 will be invalid if the error is a general loop error.)
4. See Chapter 2.13 for error codes for syntax check.

Data Backup Memory
Function Group
M1005~M1007
Number
Contents:
When the data backup memory card is installed in EH2 MPU, MPU will operate according to the On/Off of switch on
the card. If the switch is “On”, the following comparisons will be conducted and the card will be copied to MPU. If the
switch is “Off”, MPU will not perform any action.
1. M1005 = On: An error occurs in the comparison between the ciphers of MPU and the data backup memory card
and MPU does not perform any action.
2. M1006 = On: The data backup memory card has not been initialized.
3. M1007 = On: Data in the program area of the data backup memory card do not exist, it means data doesn’t exist
in the program area of data backup memory card.
Scan Time-out Timer
Function Group
M1008, D1008
Number
Contents:
1. M1008 = On: Scan time-out occurs during the execution of the program, and PLC ERROR LED indicator

a) High-speed counter is valid only when PLC is in RUN status for EH2/SVEH3/SV2, but is valid when PLC is
in RUN or STOP stauts for SA/SX/SC.
b) M1015 = On: High-speed counter D1015 is enabled only whtn PLC scans to END instruction. (Min. timing
unit of D1015: 100us)
c) Timing range of D1015: 0~32,767. When the timing reaches 32,767, the next timing restarts from 0.
d) M1015 = Off: D1015 stops timing immediately.
2. EH2/SVEH3/SV2 series MPU offers high-speed timer instruction HST. See API 196 HST for more details.
3. Example:
a) When X10 = On, M1015 will be On. The high-speed timer will start to time and record the present value in
D1015.
b) When X10 = Off, M1015 will be Off. The high-speed timer will be disabled.

Number of accel/decel sections = (TF-SF)/GF
Number of output pulses in every section:
GP = AP/Number of accel/decel sections
AP = number of accel/decel pulses
4. Note: this function is applicable only when “all” the conditions below are met.
a) Start frequency < target frequency.
DVP-PLC Application Manual 2-103
2 Functions of Devices in DVP-PLC
b) Gap frequency ≤ (target frequency – start frequency)
c) Total number of pulses > (accel/decel number of pulses × 2)
d) For start frequency and target frequency: Min. 25Hz; Max. 10kHz
e) Number of accel/decel pulses > number of accel/decel sections
When M1115 turns from “On” to “Off”, M1119 will be reset and M1116, M1117 and M1118 remain unchanged. When
PLC goes from “STOP” to “RUN”, M1115 ~ M1119 will be reset as “Off”. D1104 will only be cleared as “0” when it
turns from “Off” to “On”.
Either accel/decel pulse output function or PLSY Y0 output can be executed at a time when PLC is operating.
5. How to calculate the action time of each section
Assume the start frequency is set as 1kHz, gap frequency as 1kHz, target frequency as 5kHz, total number of
pulses as 100 and number of acceleration pulses as 40, the timing diagram of the acceleration sections is as the
figure below.

Frequency (Hz)
Time (sec)
From the conditions above, we can obtain the number of acceleration/deceleration sections is (5K – 1K)/1K = 4
and the number of output pulses in each section is 40/4 = 10. Therefore, in the diagram, t1 = (1/1K) × 10 = 10ms,
t2 = (1/2K) × 10 = 5ms, t3 = (1/3K) × 10 = 3.33ms, t4 = (1/4K) × 10 = 2.5ms.

3. The function:
All output frequency and number of pulses stated in the table above can be modified when M1133 = On and
M1135 = On. The modification will not affect the present output pulses. The present number of output pulses is
updated in every scan time. When M1133 turns from “Off” to “on”, the number will be cleared as “0”. When 1133
turns from “On” to “Off”, the last numner of output pulses will be shown.
Note:
The special high-speed pulse output function can only be used on specific Y0 output point when PLC is in RUN status.
It can coexist with PLSY (Y0) in the program and PLSY (Y1) will not be affected. If PLSY (Y0) instruction is executed
prior to this function, the function cannot be used and vice versa. When the function is executed, the general function,
general Y0 output will be invalid but Y1 ~ Y7 can be used.
The output frequency of this function is higher (max. 50kHz) than that of PLSY instruction.

Step 2: Calculate the distance (number of pulses) between every section
In X axis: x1 = x1 – 0, x2 = x2 – x1, ... x10 = x10 – x9 (see Table 5)
In Y axis: y1 = y1 – 0, y2 = y2 – y1, … y10 = y10 – y9 (see Table 5)

Step 3: Decide the execution time of every section and obtain the frequency of every section by Table 5
Assume every section executes for 500ms, the equation for frequency (Hz) of each section is: fx1 = 1÷0.5 ×

(Table 6)
Step 4: Fill Device D into table 2 and complete all steps.
Reminder 1: When Rx=Ry, you can calculate X axis, and copy X axis to Y axis (as fy1 = fx10, fy2 =
fx9, …fy10 = fx1,and y1 = x10, y2 = x9,…y10 = x1 )
Reminder 2: When drawing a counterclockwise arc, switch the index value of X axis with that of Y axis.

4. How to use and the restrictions:
a) The start frequency and target frequency have to be ≥ 200Hz; otherwise, the function will not be executed or
complete execution.
b) The start frequency and target frequency have to be < 32,700Hz. Frequency > 32,700Hz will be executed in
32,700Hz.
c) Range of gap time: 1 ~ 32,767ms (Min. unit: ms)
d) The range of gap frequency within acceleration section: 1Hz ~ 32,700Hz; within deceleration section: -1 ~
-32,700Hz. If the gap frequency is set as 0Hz, it will fail to reach target frequency in the executed section but
in the next section when the target number of pulses is reached.
e) The target number of pulses in a section has to be > (GF × GT/1,000) × [(TF - SF)/GF]; otherwise the target
may not be reached. To correct it, the user may extend gap time or increase the target number of pulses.
f) When PLC is in RUN status and there is a high-speed instruction assigning Y0 input, the instruction will be
executed prior to other instructions.
g) After M1144 = On, if M1148 has not be reached and M1144 is “Off”, deceleration will be enabled. And if
M1154 = Off at the moment, the deceleration rule will be “decelerating 200Hz every 200ms” and M1147 will
be set. The pulse output will stop when the frequency falls under 200Hz. If M1154 = On at the moment, the
output will be executed following the gap time and frequency as set by the user. The time shall not be ≤ 0 (if ≤
DVP-PLC Application Manual
2-116
2 Functions of Devices in DVP-PLC
0, it will follow the initial setting 200ms) and the frequency shall not be ≥ 0 (if = 0, it will follow the initial setting
-1kHz; if > 0, negative sign comes before the value).
h) When M1148 = On but M1144 = Off, deceleration will not be enabled and M1148 will be reset. Whenever
M1144 = Off, M1149 will be reset.
i) The number of sections being executed is determined upon the total number of sections. (Max. number of
sections = 10)
j) Acceleration or deceleration is determined upon the start frequency of the next section. That is, if the target
frequency of the current section < the start frequency of the next section, acceleration will take place in the
next section and the target frequency of the next section must > its start frequency. If the target frequency of
the current section > the start frequency of the next section, deceleration will take place in the next section
and the target frequency of the next section must < its start frequency. Correct pulse output cannot be
guaranteed if the user does not follow the rules.
k) When PLC goes from STOP to RUN, M1144 ~ M1149 will be reset to “Off”. When PLC goes from RUN to
STOP, only M1144 will be reset, not M1145 ~ M1149.
l) SA/SX/SC uses parameter table D0 ~ D999 and D2000 ~ D4999. If the used parameter table (including all
the used section parameters) falls off the range, the instruction will not be executed and M1144 will be “Off”.
5. Example 1: Calculate the number of output pulses in every acceleration/deceleration section
Assume you set the start frequency of a section as 200Hz, gap time as 100ms, gap frequency as 100Hz, target
frequency as 500Hz, and target number of pulses as 1,000:
The number of output pulses at start frequency = 200 × 100 / 1,000 = 20
The number of output pulses in the first acceleration gap = 300 × 100 / 1,000 = 30
The number of output pulses in the second acceleration gap = 400 × 100 / 1,000 = 40
The number of output pulses at target frequency = 1,000 – (40 + 30 + 20) = 910
(Please be noted that we suggest this number be bigger than 10.)
Output time for target frequency = 1 / 500 × 910 = 1,820 ms
Total time spent for this section = 1,820 + 3 × 100 = 2,120 ms

deceleration section.
b) When X0 is disabled (i.e. zero return is completed), set M1148 to disable this function.

Number
Application:
Before the instruction DDRVI is used to drive the servo, the acceleration/deceleration operation is performed on the
target position and the target frequency. After the instruction DDRVI is enabled, the operation can not be performed
on the same target position and target frequency. The advantage is that the production can be enhanced.

Device:
If M1144 is On, the function is enable. If M1144 is Off, the function is disabled.
D1144→Using the index valule of the data register
For example, k0 represents D0, k100 represents D100.
Usage: (Firmware version above 2.0)
1. Suppose the value in D1144 is k0. The value in (D0, D1) represents the number of targets, the value in (D2, D3)
represents the target frequency of Y0, the value in D1343 represents the acceleration time, the value in D1348
represents the deceleration time, and the value in D1340 represents the acceleration/deceleration frequency .
2. When M1144 is ON and the instruction DDRVI is not enabled, the operation is performed on the
acceleration/deceleration frequency and the number of targets. After DDRVI is enabled, the pulses are
generated.
3. If M1144 is On, the previous output value is executed whenever DDRVI is enabled. If users want to change the
target frequency or the number of targets, users have to reset M1144 to Off when DDRVI is disabled.
4. When this function is used, the default acceleration time and deceleration time are the values in D1343 and
D1348. Therefore, the acceleration sections and decelerations section can occupy 30 sections respectively.
5. This function can be used with the designated deceleration number function (D1232, D1233), and the
masking/marking function (M1156).

Dotted line ( ) -> A ction when I001 interruption occurs in unmasked area.
Applicable instructions: DRVI/DDRVI/PLSR/DPLSR
Usage restriction: Has to work with external interruptions, special M and special D.
Other explanations:
a) When this function is enabled, PLC will start to decelerate according to the set deceleration time. Even if the
user does not set up the number of deceleration pulses (i.e. special D = 0), or the set number of pulses is
less than the number planned for the deceleration time, PLC will still decelerate within the deceleration time.
On the contrary, if the number of deceleration pulses is more than the planned number for the deceleration
time, PLC will decelerate according to the number set in the special D.
b) Range for deceleration time: 10 ~ 10,000ms
c) There is mask interruption in CH0 high-speed output. When D1027/D1026 (32-bit) ≠ 0, the mask function
will be enabled, i.e. X0 external interruption will not be activated when the number of output pulses is within
the mask area.

Application examples:
¾ When M0 turns from Off to On, Y0 will start to output pulses and wait for the external input interruption
X0 to take place. When interruption signals occur in the acceleration section or the highest speed
section during the output, Y0 will immediately decelerate and stop the output after 100ms, and M1538 =
On.
¾ When M1538 = On, the user can reset (RST) M1156, and PLC will start to output the remaining pulses.
When all the target pulses are completed, M1029 will be On.
¾ If the external interruption occurs in the planned deceleration area, the output will not decelerate or set
M1538 to On.
b) Example 1: Immediately decelerate and pause within deceleration time
¾ Application: When external interruptions occur, the high-speed output has to achieve deceleration and
pause within the designated deceleration time. It is generally applied in the searching mark function in
single-axis motion control.

c) Program explanation:
¾ When M0 turns from Off to On, Y0 will start to output pulses and wait for the external input interruption
X0 to take place. When interruption signals occur in the acceleration section or the highest speed
section during the output, Y0 will immediately decelerate and stop the output after 100ms, and M1538 =
On.
¾ When M1538 = On, the user can reset (RST) M1156, and PLC will start to output the remaining pulses.
When all the target pulses are completed, M1029 will be On.
¾ If the external interruption occurs in the planned deceleration area, the output will not decelerate or set
M1538 to On.
d) Example 2: Immediately decelerate and pause within the number of deceleration pulses
¾ Application: When external interruptions occur, the high-speed output has to achieve deceleration and
pause within the designated number of deceleration pulses. It is generally applied in the searching mark
function in single-axis motion control.

¾ When M0 turns from Off to On, Y0 will start to output pulses. After the external input interruption X0
occurs during the output, Y0 will immediately decelerate and output 50,000 pulses before it stops and
set M1538 (pause status flag) to On.
¾ When M1538 = On, the user can reset (RST) M1156, and PLC will start to output the remaining pulses.
When all the target pulses are completed, M1029 will be On.

Contents:
1. Special D and special M for single step execution for EH2/SV/EH3/SV2:
Device No. Function
M1170 Start flag
M1171 Action flag
D1170 STEP No. of the currently executed instruction
2. The function:
a) Execution timing: The flag is valid only when PLC is in RUN status.
b) Action steps:
i) When M1170 is enabled, PLC enters the single step execution mode. PLC stays at a specific instruction,
stores the location of STEP in D1170 and executes the instsruction once.
ii) When M1171 is forced “On”, PLC executes the next instruction and stops. At the same time, PLC
auto-force “O ff” M1171 and stops at the next instruction. D1170 stores the present STEP value.
iii) When Y output is in single step execution mode, Y outputs immediately without having to wait until END
instruction is being executed.
3. Note:
a) Instruction that will be affected by scan time will be executed incorrectly due to the single step execution. For
example, when HKY instruction is executed, it takes 8 scan times to obtain a valid input value from a key.
Therefore, the single step execution will result in incorrect actions.
DVP-PLC Application Manual 2-127
2 Functions of Devices in DVP-PLC
b) High-speed pulse input/output and high-speed counter comparison instructions are executed by hardware;
therefore, they will not be affected by the single step execution.

M1174 “Number of pulses reached” flag
D1172 Output frequency (12Hz ~ 20kHz)
D1173 Output mode (K1 and K2)
D1174 The lower 16 bits of the 32 bits for the target number of pulses

D1176 The lower 16 bits of the 32 bits for the present number of pulses
D1177 The higher 16 bits of the 32 bits for the present number of pulses
2. The function:
Output frequency = 1/1 pulse cycle period (i.e. 1/T; as the figure below)
There are two output modes. K1 refers to “A-phase ahead of B-phase” and K2 refers to “B-phase ahead of
A-phase”. The number of pulses accumulates once whenever a phase gap occurs. For example, the number of
pulses in the figure below = 8, and when the number is reached, M1174 turns “On”. To clear the number, simply
turn “Off” M1172.

The output frequency, target number of pulses and selection of modes can be modified when M1172 = On and
M1174 = Off. Modification on output frequency and target number of pulses will not affect the present number of
pulses, but when the mode is modified, the present number of pulses will be cleared as “0”. The present number
of output pulses is updated in every scan time. When M1133 turns from “Off” to “on”, the number will be cleared
as “0”. When M1172 is cleared as “0” when PLC goes from STOP to RUN. When PLC goes from RUN to STOP,
the last number of pulses will be shown.

2 Functions of Devices in DVP-PLC
7. Note:
a) PLC LINK is based on Modbus communication protocol.
b) EH2/SV/EH3/SV2 supports 32 stations in the LINK and reading/writing of more than 16 data (SET1353)
(M1353 = On). SA/SX/SC supports 16 devices in the LINK and reading/writing of 16 data.
c) EH2/SV/EH3/SV2: When a MASTER PLC and a Slave PLC is connected, they are able to read/write
maximum 100 WORD data (M1353 = On). SA/SX/SC: Does not support M1353. When a Master PLC and a
Slave PLC is connected, they are able to read/write maximum 16 WORD data.
d) When the Master PLC is connected through COM2 (RS-485), baud rates and communication formats of all
Slave PLCs must be the same (set in D1120). When SA/SX/SC/EH2/SV/EH3/SV2 serves as Master, it
supports ASCII and RTU format.
e) When the Slave PLC is connected through COM2 (RS-232/RS-485/RS-422), baud rates and
communication formats of all connected Slave PLCs must be the same as those in the Master PLC (set in
D1120). When SA/SX/SC/EH2/SV/EH3/SV2 serves as Slave, it supports ASCII and RTU format.
f) When the Slave PLC is connected through COM1 (RS-232), baud rates and communication formats of all
connected Slave PLCs must be the same as those in the Master PLC (set in D1036). When
SA/SX/SC/EH2/SV/EH3/SV2 serves as Slave, it supports ASCII and RTU format.
g) When the Slave PLC is connected through COM3 (RS-232/RS-485), baud rates and communication
formats of all connected Slave PLCs must be the same as those in the Master PLC (set in D1109). When
SA/SX/SC/EH/EH2/SV serves as Slave, it only supports ASCII format (Max. baud rate = 38,400bps).
h) The start station No. (K1 ~ K214) of Slave ID1 is assigned by D1399 of Master PLC. Station No. of every
Slave and Master PLC can not be the same (set in D1121).
i) For one-to-one LINK: Connected through RS-232, RS-485, RS-422. PLC COM1, COM2, COM3 support
many communication formats.
j) For one-to-many LINK: Connected through RS-485. PLC COM1, COM2, COM3 support many
communication formats.
8. How to operate PLC LINK:
a) Set up the baud rates and communication formats of Master PLC and all connected Slave PLCs and make
them the same. COM1_RS-232: D1136; COM2_RS-232/RS-485/RS-422: D1120; COM3_RS-232/RS-485:
D1109.
b) Set up the station No. of Master PLC (in D1121) and assign the start station No. of Slave PLC from D1399
of Master PLC. Next, set up the station No. of Slave PLC. Station No. of Master and Slave cannot be the
same.
c) Set up the number of connected Slave stations and the number of data to be read in/written to Slave
stations. For EH2/SV/EH3/SV2 (M1353 = On): Enable the function of the 32 conncected Slaves and
reading/writing of more than 16 data (Max. 100 data). Next, set up the No. of D registers for storing the read
data (D1480 ~ D1495, D1576 ~ D1591) and written data (D1496 ~ D1511, D1592 ~ D1607) (See the
explanations above on special D). SA/SX/SC only supports reading/writing of 16 data.
d) Set up the length of data to be read from/written into the Slave. (If the user does not set up set them up, PLC
will follow the initial setting or the setting set in the previous operation.) (See the explanations above on
special D.)
DVP-PLC Application Manual 2-141
2 Functions of Devices in DVP-PLC
e) Set up the start communication address of the Slave to be read/written. (See the explanations above on
special D). The default start communication address of Slave to be read: H1064 = D100. The default start
communication address of Slave to be written: H10C8 = D200.
f) Operation procedure:
i) Enable the function of more than 32 stations connected to PLC LINK and reading/writing of 16 data (Max.
100 data) (M1353).
ii) Enable reading/writing of PLC LINK in the same polling (M1354).
iii) Set up PLC LINK as auto mode (M1351), or manual mode (M1352) and the times of polling (D1431).
iv) When M1355 = On, M1360 ~ M1375 (M1440 ~ M1455) will be the flags for the PLC designated to be
connected to. When M1355 = Off, there will be detection on the slaves connected, and M1360 ~ M1375
(M1440 ~ M1455) will become the flags for the existence of connected PLC.
v) Enable PLC LINK (M1350).
9. How does Master PLC work:
a) To detect station No. of Slave: Set up the LINK to be automatic mode (M1351 = On) or manual mode
(M1352 = On) (Note: M1351 and M1352 cannot be “On” at the same time) When M1350 = On, Master PLC
starts to detect the total number of Slave stations connected to the LINK and records the number in D1433.
The detection time may differ upon the number of Slave stations and the setting of communication timeout
in D1129.
b) When M1360 ~ M1375, M1440 ~ M1455 = On, Slave ID1 ~ ID32 exist.
c) If the detected number Slave stations is 0, M1350 will be “Off” and the LINK will be stopped.
d) M1353 and M1354 should be set before PLC LINK is enabled. When PLC LINK is executed, the two special
M will not afftec the action of PLC LINK.
e) When M1355 = On, M1360 ~ M1375 (M1440 ~ M1455) will be the flags for the PLC designated to be
connected to. Therefore, no matter how many PLCs are actually connected, the PLC LINK function will
continue to send read/write instruction in cycle according to the designated flags.
f) When 1353 = On, D1480 ~ D1607 (read/write buffer of SLAVE ID1 ~ 4) will be used for storing the No. of
registers D for Slave ID1 ~ ID32, The No. of register D shall not be “> 9,900” or “< 0” ; otherwise, PLC will
auto-set it as 9,900. The data length shall not be “ > 100” or “<0”; otherwise, PLC will auto-set it as 100.
g) When M1354 = On, set up Modbus Function H17 (synchronous read/write) for PLC LINK communication. If
the number of written data is set to be “0”, the communication of PLC LINK will be automatically converted
into Modbus Function H03 (read multiple words). Similarly, if the number of read data is set to be “0”, the
communication of PLC LINK will be converted into Modbus Function H06 (write 1 word) or Modbus Function
H10 (write multiple words).
h) If the number of read/written data > 16, the time for timeout (D1129) shall be > 500ms in case
communication timeout may occur.
i) After M1350 = On, Master PLC detects the ID of Slave E PLC only right after the LINK is enabled and will
not detect the ID again afterward.
j) After the detection on Slave PLCs is completed, Master PLC starts to read and write data from/into every
Slave PLC. Please be noted that, Master PLC only reads/writes data from/into the detected Slave PLC.
DVP-PLC Application Manual
2-142
2 Functions of Devices in DVP-PLC
Master PLC will not read/write from/into the new Slave PLC to the LINK, unless it re-detects the ID of Slave
PLCs.
k) Master PLC conducts reading before writing. The ranges of Slave PLCs to be read/written will follow the
setting.
l) Master PLC will move to the reading/writing of the next Slave PLC after finishing reading/writing the current
Slave PLC.
10. Auto mode and maual mode:
a) Auto mode (M1351 = On): Master PLC automatically reads/writes from/to Slave PLC and stops when
M1350/M1351 = Off to terminate PLC LINK.
b) Manual mode (M1352 = On): When M1352 = On, you also have to set up the times of polling in D1431. One
time of polling refers to the completion of reading and writing all Slaves. After the PLC LINK is enabled,
D1432 will start to count how many LINKs have been done. When D1431 = D1432, PLC LINK stops and
M1352 is reset. To re-enable PLC LINK in the manual mode, simply turn “On” M1352 and D1431 will starts
to count the times of LINK again.
c) Note:
i) Automatic mode (M1351) and manual mode (M1352) cannot be “On” at the same time; otherwise PLC LINK
will stop and M1350 will be reset.
ii) For EH2/SV/EH3/SV2: M1350 has to be reset before switching between automatic mode and manual mode.
For SA/SX/SC: No such restriction.
iii) When M1355 = On, M1360 ~ M1375 (M1440 ~ M1455) will be the flags for the PLC designated to be
connected to. Therefore, no matter how many PLCs are actually connected, the PLC LINK function will
continue to send read/write instruction in cycle according to the designated flags.
iv) The communication timeout is adjustable (D1129, range: 200 ≤ D1129 ≤ 3,000). If D1129 falls out the range,
PLC will determine the time by 200 or 3,000. The timeout setting of PLC LINK is only valid if it is set before
the LINK is enabled. If the number of read/written data >16, the communication timeout shall be > 500ms in
case a communication timeout may occur.
v) PLC LINK is only workable when the baud rate is > 1,200bps. If the baud rate is < 9,600, the communication
timeout setting shall be > 1 second.
vi) The communication is unworkable when the number of read/written data = 0.
vii) PLC LINK does not support the reading/writing from/to 32-bit counters (C200 ~ C255).
viii) The maximum set value for D1399 is 230. If the set value is bigger than 230, PLC will automatically correct it
as 230. The minimum set value for D1300 is 1. If the set value is smaller than 1, PLC will automatically
correct it as 1.
ix) Setting up of D1399 has to be done before PLC LINK is enabled. After PLC LINK is enabled, setting up
D1399 will not result in any changes.
x) Advantages (when using a multi-layer network): Assume you are using a network with 3 layers and the first
and second layer and the second and third layer are using PLC LINK for communication, the IDs in the
second and third layer will definitely overlap due to the old version of PLC LINK detects only Slave ID#1 ~ 16.
When the IDs of Slave and Master overlap, PLC LINK will ignore the PLC of overlapping ID, resulting in the
DVP-PLC Application Manual 2-143
2 Functions of Devices in DVP-PLC
situation that the third layer can have only 15 PLCs. Therefore, D1399 allows more PLCs connected in a
multi-layer network.

not affect the execution.
Registers designated in D1480 ~ D1495, D1576~D1591 (starting register for data read from Slave ID#1 ~
16) and D1496 ~ D1511, D1592 ~ D1607 (starting register for data written into Slave ID#1 ~ 16) can only
be register D, and every special D will correspond to one Slave ID#, e.g. D1480 corresponds to ID1,
D1481 to ID2, and so on.
D1480 ~ D1495, D1576 ~ D1591, D1496 ~ D1511 and D1592 ~ D1607 have to be set before PLC LINK is
enabled. In the execution of PLC LINK, you can modify the contents in these special Ds, but the modified
results will take effect in the next PLC LINK polling.
If the ID# designated by D1480 ~ D1495, D1576 ~ D1591, D1496 ~ D1511 and D1592 ~ D1607 is smaller
than 0 or bigger than 9,900, PLC will automatically correct the ID# into 9,900.
If M1353 is not enabled during the execution of PLC LINK, the range for D1434 ~ D1449, D1544 ~ D1559
(number of data read from Slave ID#) and D1450 ~ D1465, D1560 ~ D1575 (numbere of data written into
Slave ID#) will be 0 ~ 16. If the setting in the special D exceeds the range, PLC will correct it to 16. When
M1353 is enabled, the range will be 0 ~ 100. If the setting in the special D exceeds the range, PLC will
correct it to 100.
You can modify the settings in D1434 ~ D1449, D1544 ~ D1559, D1450 ~ D1465 and D1560 ~ D1575
during the execution of PLC LINK, but the modified results will take effect in the next PLC LINK polling.

If the reaction speed of the RS-485 IC direction control signal pin of the Slave is slow, it is suggested that
you do not enable I170.
You can set up D1399 (starting Slave ID designated by PLC LINK), and the ID# of the next 15 Slaves
have to be in sequence. For example, when D1399 is set as K20, the Master PLC will detect Slave ID# 20
~ 35.

2.13 Error Codes
After you write the program into the PLC, the illegal use of operands (devices) or incorrect syntax in the program
will result in flashing of ERROR indicator and M1004 = On. In this case, you can find out the cause of the error by
checking the error code (hex) in special register D1004. The address where the error occurs is stored in the data
register D1137. If the error is a general loop error, the address stored in D1137 will be invalid.

Operand
C-D C200 ~ C255, D0 ~ D9999
Explanations:
1. DCNT is the instruction for enabling the 32-bit high-speed counters C200 ~ C255.
2. For general purpose addition/subtraction counters C200 ~ C234, when DCNT goes from Off to On, the present
value in the counter will pulse 1 (counting up) or minus 1 (counting down) according to the modes set in special
M1200 ~ M1235.
3. For high-speed addition/subtraction counters C235 ~ C255, when the high-speed counting pulse input goes
from Off to On, the counting will start its execution. For the input terminals (X0 ~ X17) and counting methods

(counting up/down) of the high-speed counter, see Chapter 2.7 Numbering and Function of Counter [C] for more
details.
4. When DCNT is Off, the counting will stop, but the existing present value in the counter will not be cleared. To
clear the present value and the contact, you have to use the instruction RST C2XX. Use externally designated
input points to clear the present values and contacts of high-speed addition/subtraction counters C235 ~ C255.

Operand
Explanations:
1. MC is the main-control start instruction. When MC instruction is executed, the execution of instructions between
MC and MCR will not be interrupted. When MC instruction is Off, the actions of the instructions between MC and
MCR are:
Instruction type Explanation
Present value = 0
General purpose timer Coil is Off, No action for the contact
Accumulative timer Coil is Off, present value and contact stay intact
Present value = 0
Subroutine timer Coil is Off, No action for the contact
Counter Coil is Off, present value and contact stay intact
Coils driven by OUT
instruction All Off
Devices driven by SET and
RST instructions Stay intact
All disabled.
The FOR-NEXT nested loop will still execute back and forth for N times.
Application instructions Instructions between FOR-NEXT will act as the instructions between MC
and MCR.
2. MCR is the main-control end instruction that is placed in the end of the main-control program. There should not
be any contact instructions prior to MCR instruction.
3. MC-MCR main-control program instructions support the nested program structure (max. 8 layers) and please
use the instruction in the order N0 ~ N7.

4.2 Sequential Function Chart (SFC)
In automation, we always need electric control to work with mechanical control for an automation control. The
sequential control can be divided into several orderly steps (or stages). Each step has its actions that should be
completed and the transition from one step to another normally requires some criteria. The action of the last step
finishes when all criteria is true and the beginning of the next step will clear the actions of the last step. This is the
concept of designing a sequential function chart (SFC).
DVP-PLC Application Manual
4-2
4 Step Ladder Instructions
Features:
1. No sequential design is required for constant step actions, and PLC will
automatically execute the interlocking and dual outputs among all status. An
easy sequential design is the only thing required to make the machine work
normally.
2. The actions in SFC are easy to understand, adjust for a trial operation, detect
the errors and maintain.
3. SFC is a type of diagram editing. The structure of a SFC looks like a flow chart.
Every No. of the step relay S inside the PLC represents a step, equal to every
processing procedure in a flow chart. When the current procedure is
completed, the program will move to the next step according to the set
transition criteria. Therefore, you can repeat the cycle and obtain the result you
desire.
4. See the SFC chart in the right hand side: The initial step S0 transfers to a
general purpose step S21 by making the status transition condition X0
condition true. S21 transfer to S22 or jumps to S24 by making X1 or X2 true. In
step S25, X6 will be true and the chart will return to S0 to complete a cycle. The
cycle and be repeated to reach a cyclic control.

Transition condition between steps.
Alternative divergence. The same step transfers to a corresponding step by different transition
condition.
Alternative convergence. More than 2 steps transfer to the same step by transition condition.
Simultaneous divergence. The same step transfers to more than 2 steps by the same transition
condition.
Simultaneous convergence. More than 2 steps transfer to the same step by a single transition
condition.
4.3 How does a Step Ladder Instruction Work?
STL instruction is used for designing the syntax of a sequential function chart (SFC), making the program
designing similar to drawing a flow chart and allowing a more explicit and readable program. From the figure in the left
hand side below, we can see very clearly the sequence to be designed, and we can convert the sequence into the
step ladder diagram in the right hand side.
DVP-PLC Application Manual 4-3
4 Step Ladder Instructions
RET instruction has to be written at the end of every step sequence, representing the end of a sequence. There
can be more than one step sequence in a program. Therefore, we have to write in RET at the end of every step
sequence. There is no limitation on the times of using RET which is used together with S0 ~ S9.
If there is no RET instruction at the end of a step sequence, errors will be detected by WPL editor.

1. Actions of Step Ladder:
A step ladder is composed of many steps and every step controls an action in the sequence. The step ladder
has to:
a) Drive the output coil
b) Designate the transition condition
c) Designate which step will take over the control from the current step
Example:

When X0=On,
S20 = On,

Explanation:
When S10 = On, Y0 and Y1 will be On. When X0 = On, S20 will be On and Y10 will be On. When S10 = Off, Y0
will be Off and Y1 will be On.
2. Timing Diagram of Step Ladder:
When the status contact Sn = On, the circuit will be activated. When Sn = Off, the circuit will be disactivated. The
actions will delay for 1 scan time.

3. Repeated Use of Output Coil:
a) You can use output coils of the same No. in different steps.
b) See the diagram in the right. There can be the same
output device (Y0) among different statuses. Y0 will be On
when S10 or S20 is On. Such as right diagram, there is the
same output device Y0 in the different state. No matter
S10 or S20 is On, Y0 will be On.
c) Y0 will be Off when S10 is transferring to S20. After S20 is
On, Y0 will output again. Therefore in this case, Y0 will be
On when S10 or S20 is On.
d) Normally in a ladder diagram, avoid repeated use of an
output coil. The No. of output coil used by a step should
also avoid being used when the step ladder diagram
returns to a general ladder diagram.

4. Repeated Use of Timer:
The timers in EH2/SV series MPU are the same as general
output points and can be repeatedly used in different steps.
This is one of the features of the step ladder diagram.
However, in a general ladder diagram, it is better not be
repeatedly use the output coil. Also avoid using the No. of the
output coil used by a step after the step ladder diagram returns
to a general ladder diagram.
Note: See the figure in the right. The timers in ES/EX/SS/SA/
SX/SC series MPU can be used repeatedly in non-adjacent
steps.

5. Transfer of Step:
SET Sn and OUT Sn instructions are used to enable (or transfer to) another step. When the control power is
shifted to another step, the status of the previous step S and the action of the output point will be cleared. Due to
that there can be many step control sequences (i.e. the step ladder diagram starting with S0 ~ S9) co-existing in
the program. The transfer of a step can take place in the same step sequence, or be transferred to different step
sequence. Therefore, there are some slight differences regarding how to use SET Sn and OUT Sn. See the
explanations below.
SET Sn Used for driving the next
step in the same
sequence. After the
transition, all output from
the previous status will be
cleared.

When SET S12 instruction is executed,

OUT Sn Used for returning to the initial step in the same step sequence. Also for jumping up/down to
non-adjacent steps in the same sequence, or separating steps in different sequences. After the
transition, all output from the previous status will be cleared.
c Returning to the
initial step in the
same sequence.
d Jumping up/down
to non-adjacent
steps in the same
sequence.

6. Cautions for Driving Output Point:
See the figure below. After the step point and once LD or LDI instructions are written into the second line, the
bus will not be able to connect directly to the output coil, and errors will occur in the compilation of the ladder
diagram. You have to correct the diagram into the diagram in the right hand side for a correct compilation.

7. Restrictions on Using Some Instructions:

8. Other Points to Note:
The instruction used for transferring the step (SET S□ or OUT S□) can only be executed after all the relevant
outputs and actions in the current status are completed. See the figure below. The executed results by the PLC are
the same, but if there are many conditions or actions in S10, it is recommended that you modify the diagram in the
left hand side into the diagram in the right hand side. SET S20 is only executed after all relevant outputs and
actions are completed, which is a more explicit sequence.

4.4 Things to Note for Designing a Step Ladder Program
1. The first step in the SFC is called the “initial step", S0 ~ S9. Use the initial step as the start of a sequence and end a
complete sequence with RET instruction.
2. If STL instruction is not in use, step S can be a general-purpose auxiliary relay.
3. When STL instruction is in use, the No. of step S cannot be repeated.
4. Types of sequences:
DVP-PLC Application Manual
4-8
4 Step Ladder Instructions
Single sequence: There is only one sequence without alternative divergence, alternative convergence, simultaneous
divergence and simultaneous convergence in a program.
Complicated single sequence: There is only one sequence with alternative divergence, alternative convergence,
simultaneous divergence and simultaneous convergence in a program.
Multiple sequences: There are more than one sequence in a program, maximum 10 sequences, S0 ~ S9.
5. Separation of sequence: Multiple sequences are allowed to be written into the step ladder diagram.
a) See the diagram in the right hand side. There are two
sequences S0 and S1. The program writes in S0 ~ S30 first
and S1 ~ S43 next.
b) You can designate a step in the sequence to jump to any step
in another sequence.
c) When the condition below S21 is true, the sequence will jump
to step S42 in sequence S1, which is called “separating the
step”.
S0
S21
S30
OUT
OUT
S1
S41
S43
OUT
S42
6. Restrictions on diverging sequence: See 4.5 for example
a) You can use maximum 8 diverged steps in a divergence sequence.
b) You can use maximum 16 loops in multiple divergence sequences or in simultaneous sequences combined into
one sequence.
c) You can designate a step in the sequence to jump to any step in another sequence.
7. Reset of the step and the inhibiting output:
a) Use ZRST instruction to reset a step to be Off.
b) Make M1034 = On to inhibit output Y.
8. Latched step:
The On/Off status of the latched step will be memorized when the power of the PLC is switched off. When the
PLC is re-powered, the status before the power-off will be recovered and the execution will resume. Please be
aware of the area for the latched steps.
9. Special auxiliary relays and special registers: See 4.6refer to chapter 4.6 IST instruction for more details.

4.5 Types of Sequences
Single Sequence: The basic type of sequences
The first step in a step ladder diagram is called the initial step, which can be S0 ~ S9. The steps following the
initial step are general steps, which can be S10 ~ S1023. If you are using IST instruction, S10 ~ S19 will become the
steps for zero return.
a) Single sequence without divergence and convergence
After a sequence is completed, the control power on the steps will be given to the initial step.

b) Structure of alternative divergence
When the individual condition at the current status is true, the step will be transferred to another individual step.
See the diagrams below. When X0 = On, S20 will be transferred to S30; when X1 = On, S20 will be transferred to
S31; when X2 = On, S20 will be transferred to S32.

c) Structure of the simultaneous convergence
See the ladder diagram below. A continuous STL instruction represents a simultaneous convergence. When the
condition is true after a continuous output, the step will be transferred to the next step. In the simultaneous
convergence, only when several conditions are true will the transfer be allowed.

Restrictions on Divergence Sequence:
1. You can use maximum 8 divergence steps in a divergence sequence. As the diagram below, there are maximum
8 diverged steps S30 ~ S37 after step S20.
2. You can use maximum 16 loops in multiple divergence sequences or in simultaneous sequences combined into
one sequence. As the diagram below, there are 4 steps diverged after S40, 7 steps diverged after S41, and 5
steps diverged after S42. There are maximum 16 loops in this sequence.
3. You can designate a step in the sequence to jump to any step in another sequence.

Operands:
S: Start device in the designated operation mode D1: The smallest No. of designated step in auto mode
D2: The biggest No. of designated step in auto mode
Explanations:
1. S will occupy 8 consecutive points.
2. Range of D1 and D2: for SA/SX/SC/EH2/SV/EH3/SV2 S20 ~ S899; for ES/EX/SS S20 ~ S127; D2 > D1.
3. See the specifications of each model for their range of use.
4. IST instruction can only be used once in the program.
5. Flags: M1040 ~ M1047. See remarks for more details.
6. IST instruction is a handy instruction specifically for the initial status of step ladder control procedure to

accommodate special auxiliary relay.
Program Example 1:
1. Use of IST instruction
M1000
IST X10 S20 S60
S X10: Individual operation
X11: Zero return
X12: Step operation
X13: One cycle operation
X14: Continuous operation
X15: Zero return enabled switch
X16: Start switch
X17: Stop switch
2. When IST instruction is being executed, the following special auxiliary relays will switch automatically.
M1040: Operation forbidden
M1041: Operation starts
M1042: Pulse output enabled
M1047: STL monitor enabled
S0: Initiates manual operation
S1: Initiates zero return
S2: Initiates auto operation
3. S10 ~ S19 are for zero return and cannot be used as general steps. When S0 ~ S9 are in use, S0 ~ S2 represent
manual operation mode, zero return mode and auto operation mode. Therefore, in the program, you have to write
the circuit of the three steps in advance.
4. When switched to S1 (zero return) mode, any On in S10 ~ S19 will result in no zero return.
5. When switched to S2 (auto operation) mode, any On of the S in D1 ~ D2 or M1043 = On will result in no auto
operation.
Program Example 2:
1. Robot arm control (by IST instruction):
a) Motion request: Separate the big ball and small ball and move them to different boxes. Configure the control
panel for the control.
b) Motions of the robot arm: descending, clipping ball, ascending, right shifting, releasing ball, ascending, left
shifting.
c) I/O devices:

2. Operation modes:
Manual operation: Turn On/Off of the load by a single button.
Zero return: Press the zero return button to automatically zero-return the machine.
Auto operation:
a) Single step operation: Press “auto start” button for every one step forward.
b) One cycle operation: Press “auto start” button at the zero point. After a cycle of auto operation, the operation
will stops at the zero point. Press “auto stop” button in the middle of the operation to stop the operation and
press “auto start” to restart the operation. The operation will resume until it meets the zero point.

c) Continuous operation: Press “auto start” button at the zero point to resume the operation. Press “auto stop” to
operate until it meets the zero point.

5.2 Composition of Application Instruction
An application instruction has two parts: the instruction and operands.
Instruction: The function of the instruction
Operands: Devices for processing the operations of the instruction
The instruction part of an application instruction usually occupies 1 step, and one operand occupies 2 or 4 steps
depending on the instruction is a 16-bit or 32-bit one.

Input of application instruction:
Some application instructions are only composed of the instruction part (mnemonic), e.g. EI, DI, WDT…. Most
application instructions are composed of the instruction part and many operands.
DVP-PLC Application Manual 5-7
5 Categories & Use of Application Instructions
The application instructions for DVP-PLC are represented as API 00 ~ API 246. Every application instruction
has its own mnemonic. For example, the mnemonic of API 12 is MOV. If you are using the ladder diagram editing
software (WPLSoft) to input API 12 into the program, you only have to enter “MOV”. If you are using the handheld
programming panel (HPP) to input API 12 into the program, you will have to enter the API No. “12”.
Different application instructions designate different operands. Take MOV instruction for example:
X0
MOV K10 D10
Instruction
mnemonic
Operands
MOV instruction is to move the operand designated in S to the operand designated in D.
S Source operand: If there are more than 1 source operands, they will be represented as S1, S2, ….
D Destination operand: If there are more than 1 destination operands, they will be represented as
D1, D2, ….
If the operand can only be constant K/H or a register, it will be represented as m, m1, m2, n, n1, n2, ….
Length of operand (16-bit instruction or 32-bit instruction)
Depending on the contents in the operand, the length of an operand can be 16-bit or 32-bit. Therefore, a
16-bit instruction is for processing 16-bit operands, and 32-bit instruction is for processing 32-bit operands. The
32-bit instruction is indicated by adding a “D” before the 16-bit instruction.
16-bit MOV instruction
X0
K10 D10MOV
When X0 = On, K10 will be sent to D10.
32-bit DMOV instruction
X1
D10 D20DMOV
When X1 = On, the content in (D11, D10) will be sent
to (D21, D20).
Continuous execution instruction and pulse execution instruction
Continuous execution and pulse execution are the two types of execution for an application instruction. Due to
that the execution time required will be shorter when the instruction is not executer, the pulse execution
instructions are used more to shorten the scan period. Instructions marked with a “P" following the mnemonic are
pulse execution instruction. Some instructions are mostly used as pulse execution type, e.g. INC, DEC, the kind of
displacement instructions.
DVP-PLC Application Manual
5-8
5 Categories & Use of Application Instructions
Pulse execution instruction
X0
D10 D12MOVP
When X0 goes from Off to On, MOVP instruction will be
executed once and the instruction will not be executed
again in the scan period.
Continuous execution instruction
X1
D10 D12MOV
In every scan period when X1 = On, MOV instruction will
be executed once.
In the two figures, when X0, X1 = Off, the instruction will not be executed, and the content in operand D will
remain unchanged.
Designation of operands
1. Bit devices X, Y, M, and S can be combined into word device, storing values and data for operaions in the form
of KnX, KnY, KnM and KnS in an application instruction.
2. Data register D, timer T, counter C and index register E, F are designated by general operands.
3. A data register is usually in 16 bits, i.e. of the length of 1 register D. A designated 32-bit data register refers to
2 consecutive register Ds.
4. If an operand of a 32-bit instruction designates D0, the 32-bit data register composed of (D1, D0) will be
occupied. D1 is the higher 16 bits; D0 is the lower 16 bits. The same rule also apply to timer T, 16-bit timers
and C0 ~ C199.
5. When the 32-bit counters C200 ~ C255 are used as data registers, they can only be designataed by the
operands of 32-bit instructions.
Format of operand
1. X, Y, M, and S can only On/Off a single point and are defined as bit devices.
2. 16-bit (or 32-bit) devices T, C, D, and registers E, F are defined as word devices.
3. You can place Kn (n = 1 refers to 4 bits. For 16-bit instruction, n = K1 ~ K4; for 32-bit instruction, n = K1 ~ K8)
before bit devices X, Y, M and S to make it a word device for performing word-device operations. For example,
K1M0 refers to 8 bits, M0 ~ M7.
X0
K2M0 D10
MOV
When X0 = On, the contents in M0 ~ M7 will be moved to
bit0 ~ 7 in D10 and bit8 ~ 15 will be set to “0”.

Flags
1. General flags
a) The flags listed below are for indicating the operational result of the application instruction.
M1020: zero flag M1022: carry flag
M1021: borrow flag M1029: execution of instruction is completed
All flags will turn On or Off according to the operational result of an instruction. For example, the
execution result of operation instructions ADD/SUB/MUL/DVI will affect the status of M1020 ~ M1022. When
the instruction is not executed, the On/Off status of the flag will be held. The status of the four flags relates to
many instructions. See relevant instructions for more details.
b) Example of M1029
When the contact of DSW (Digital Switch) instruction is On, 4 output points will automatically act in cycle
at the frequency of 0.1 second in order to read the set value of the digital switch. If the contact goes Off
during the execution, the action will be disable. When it is On again, the disabled action will be re-executed. If
you do not wish the action to be disabled, you can take the circuit below as a reference.
X0
SET M0
M0
DSW X10 Y10 D0 K0
RST M0
M1029
When X0 = On, DSW will be enabled.
When X0 = Off, M0 will be Off only when DSW
completes a cycle and M1029 = On.
2. Error Operation Flags
Errors occur during the execution of the instruction when the combination of application instructions is
incorrect or the devices designated by the operand exceed their range. Other than errors, the flags listed in
the table below will be On, and error codes will also appear.
DVP-PLC Application Manual

5 Categories & Use of Application Instructions
Device Explanation
M1067
D1067
D1069
When operational errors occur, M1067 will be On. D1067 displays the error code. D1069
displays the step where the error occurs. Other errors occurring will update the contents in
D1067 and D1069. M1067 will be Off when the error is eliminated.
M1068
D1068
When operational errors occur, M1068 will be On. D1068 displays the step where the error
occurs. Other errors occurring wil not update the content in D1068. You have to use RST
instruction to reset M1068 to Off; otherwise M1068 will keep being On.
3. Flags for expanding functions
Some application instructions can use some special flags to expand their functions or complete special
functions. For example, the communication instruction RS can use M1161 to switch between 8-bit and 16-bit
transmission mode.
Times of using instructions
There are limitation on the times of using some instructions in the program. However, you can use index register
modification in the operands to expand the functions of the instruction.
1. Can be used only once in the program:
API 58 PWM (ES series MPU) API 60 IST (ES/SA/EH2/EH3 series MPU)
API 74 SEGL (ES series MPU) API 155 DABSR (SC/EH2/EH3 series MPU)

5. In SA series MPU, there is on limitation on the times of using the high-speed output instructions PLSY, PWM and
PLSR, bit only one high-speed output instruction will be enabled in every scan.
6. In EH2/EH3 series MPU, there is no limitation on the times of using hardware high-speed counter instructions
DHSCS, DHSCR and DHSZ, but when the three instructions are enabled at the same time, DHSCS will occupy 1
memory unit, DHSCR 1 memory unit, and DHSZ 2 memory units. The total memeory units occupied by the three
instructions cannot be more than 8 units. If there are more than 8 memory units occupied, the PLC system will
execute the instruction that is first scanned and enabled and ignore the rest.
5.3 Handling of Numeric Values
Devices only with On/Off status are called bit devices, e.g. X, Y, M and S. Devices used exclusively for storing
numeric values are called word devices, e.g. T, C, D, E and F. Bit device plus a specific bit device (place a digit
before the bit device in Kn) can be used in the operand of an application instruction in the form of numeric value.
n = K1 ~ K4 for a 16-bit value; n = K1 ~ K8 for a 32-bit value. For example, K2M0 refers to a 8-bit value composed of
M0 ~ M7.

Low byte
Low byte
K1M0, K2M0, and K3M0 are transmitted to 16-bit registers and the vacant high bits will be filled in “0”. The same
rule applied to when K1M0, K2M0, K3M0, K4M0, K5M0, K6M0, and K7M0 are transmitted to 32-bit registers and
the vacant high bits will be filled in “0”.
In the 16-bit (or 32-bit) operation, if the contents of the operand are designated as bit devices K1 ~ K3 (or K4 ~ K7),
the vacant high bits will be regarded as “0”. Therefore, the operation is a positive-value one.

M0
BIN K2X4 D0
The BCD value composed of X4 ~ X13 will be converted to BIN
value and sent to D0.
You can choose any No. for bit devices, but please make the 1s digit of X and Y “0”, e.g. X0, X10, X20, …Y0, Y10…,
and the 1s digit of M and S “8’s multiple” (“0” is still the best choice), e.g. M0, M10, M20….
Designating continuous device No.
Take data register D for example, continuous D refers to D0, D1, D2, D3, D4….
For bit devices with specifically designated digit, continuous No. refers to:
K1X0 K1X4 K1X10 K1X14…
K2Y0 K2Y10 K2Y20
Y2X30…
K3M0 K3M12 K3M24
K3M36…
K4S0 K4S16 K4S32
K4S48…
Please follow the No. in the table and do not skip No. in case confusion may occur. In addition, if you use K4Y0 in
the 32-bit operation, the higher 16 bits will be regarded as “0”. For 32-bit data, please use K8Y0.
The operations in DVP-PLC are conducted in BIN integers. When the integer performs division, e.g. 40 ÷ 3 = 13
and the remainder is 1. When the integer performs square root operations, the decimal point will be left out. Use
decimal point operation instructions to obtain the decimal point.

M
BE
S.121 ××− −, in which B = 127
Therefore, the range for the 32-bit floating point is ±2-126 ~ ±2+128, i.e. ±1.1755 × 10-38 ~ ±3.4028 × 10+38
Example 1: Representing "23" in 32-bit floating point
Step 1: Convert “23” into a binary value: 23.0 = 10111
Step 2: Normalize the binary value: 10111 = 1.0111 × 24, in which 0111 is mantissa and 4 is exponent
Step 3: Obtain the exponent: ∵ E – B = 4 E – 127 = 4 ∴ E = 131 = 100000112
Step 4: Combine the sign bit, exponent and mantissa into a floating point
0 10000011 011100000000000000000002 = 41B8000016
Example 2: Representing “-23.0” in 32-bit floating point
The steps required are the same as those in Example 1. The only difference is you have to alter the sign bit into “1”.
DVP-PLC uses registers of 2 continuous No. to combine into a 32-bit floating point. For example, we use registers
(D1, D0) for storing a binary floating point as below:
S E7 E6 E5 E1 E0 A22 A21 A20 A6 A5 A4 A3 A2 A1 A0
b0b1b2b3b4b5b6b20b21b22b23b24b28b29b30b31
222 222 22 2 222 222
7 6 5 1 0 -1 -2 -3 -17 -18 -19 -20 -21 -22 -23
D1(b15~b0) D0(b15~b0)
8 bits of exponent 23 bits of mantissa
Sign bit (0: positive 1: negative)
When b0~b31 is 0, the content is 0.
Hidden decimal point
Decimal Floating Point
Since the binary floating point are not very user-friendly, we can convert it into a decimal floating point for use.
Please be noted that the decimal point operation in DVP-PLC is still in binary floating point.
The decimal floating point is represented by 2 continuous registers. The register of smaller No. is for the constant
while the register of bigger No. is for the exponent.
Example: Storing a decimal floating point in registers (D1, D0)
Decimal floating point = [constant D0] × 10 [exponent D1 ]
Constant D0 = ±1,000 ~ ±9,999
Exponent D1 = -41 ~ +35
The constant 100 does not exist in D0 due to 100 is represented as 1,000 × 10-1. The range of decimal floating point
is ±1175 × 10-41 ~ ±3402×10+35.

The decimal floating point can be used in the following instructions:
D EBCD: Converting binary floating point to decimal floating point
D EBIN: Converting decimal floating point to binary floating point
Zero flag (M1020), carry flag (M1021), carry flag (M1022) and the floating point operation instructions:
Zero flag: M1020 = On if the operational result is “0”.
Borrow flag: M1021 = On if the operational result exceeds the minimum unit.
Carry flag: M1022 = On if the absolute value of the operational result exceeds the range of use.
5.4 E, F Index Register Modification
The index registers are 16-it registers. There are 2 points of E, F in ES/EX/SS, 8 points E0 ~ E3 and F0 ~ F3 in
SA/SX/SC, and 16 points E0 ~ E7 and F0 ~ F7 in EH2/SV/EH3 series MPU.
F0 E0
E0
F0
16-bit 16-bit
32-bit
High byte Low byte
E and F index registers are 16-bit data registers, can be read and
written.
If you need a 32-bit register, you have to designate E. In this case, F
will be covered up by E and cannot be used; otherwise, the contents
in E may become incorrect. (We recommend you use MOVP
instruction to reset the contents in D to 0 when the PLC is switched
on.)
Combination of E and F when you designate a 32-bit index register:
(E0, F0), (E1, F1), (E2, F2), ... (E7, F7)
MOV K20E0 D10F0
E0 = 8 F0 = 14
20 + 8 = 28 10 + 14 = 24
Transmission K28 D24
See the diagram in the left hand side. E, F index register
modification refers to the content in the operand changes with
the contents in E and F.
For example, E0 = 8 and K20E0 represents constant K28 (20
+ 8). When the condition is true, constant K28 will be
transmitted to register D24.
Devices modifiable in ES/EX/SS series MPU: P, X, Y, M, S, KnX, KnY, KnM, KnS, T, C, D.
Devices modifiable in SA/SX/SC series MPU: P, X, Y, M, S, KnX, KnY, KnM, KnS, T, C, D
Devices modifiable in EH2/SV/EH3 series MPU: P, I, X, Y, M, S, K, H, KnX, KnY, KnM, KnS, T, C, D
E and F can modify the devices listed above but cannot modify themselves and Kn. K4M0E0 is valid and
K0E0M0 is invalid. Grey columns in the table of operand at the beginning page of each application instruction indicate
the operands modifiable by E and F.
DVP-PLC Application Manual 5-15
5 Categories & Use of Application Instructions
If you need to modify device P, I, X, Y, M, S, KnX, KnY, KnM, KnS, T, C and D by E, F, you have to select a
16-bit register, i.e. you can designate E or F. To modify constant K and H in a 32-bit instruction, you have to select a
32-bit register, i.e. you have to designate E.
When you use the instruction mode in WPLSoft to modify constant K and H, you have to use @, e.g.
"MOV K10@E0 D0F0”

ES EX SS SA SX SC EH SV EH3

Operands:
S: The destination pointer of conditional jump
Explanations:
1. Operand S can designate P
2. P can be modified by index register E, F
3. In ES/EX/SS series models: Operand S can designate P0 ~ P63
4. In SA/SX/SC/EH/EH2/SV series models: Operand S can designate P0 ~ P255
5. When the user does not wish a particular part of PLC program in order to shorten the scan time and execute
dual outputs, CJ instruction or CJP instruction can be adopted.
6. When the program designated by pointer P is prior to CJ instruction, WDT timeout will occur and PLC will stop
running. Please use it carefully.
7. CJ instruction can designate the same pointer P repeatedly. However, CJ and CALL cannot designate the same
pointer P; otherwise an error will occur.
8. Actions of all devices while conditional jumping is being executed.
a) Y, M and S remain their previous status before the conditional jump takes place.
b) Timer 10ms and 100ms that is executing stops.
c) Timer T192 ~ T199 that execute the subroutine program will continue and the output contact executes normally.
d) The high-speed counter that is executing the counting continues counting and the output contact executes
normally.
e) The ordinary counters stop executing.
f) If the “reset instruction” of the timer is executed before the conditional jump, the device will still be in the reset
status while conditional jumping is being executed.
g) Ordinary application instructions are not executed.
h) The application instructions that are being executed, i.e. API 53 DHSCS, API 54 DHSCR, API 55 DHSZ, API 56
SPD, API 57 PLSY, API 58 PWM, API 59 PLSR, API 157 PLSV, API 158 DRVI, API 159 DRVA, continue being
executed.
Program Example 1:
1. When X0 = On, the program automatically jumps from address 0 to N (the designated label P1) and keeps its
execution. The addresses between 0 and N will not be executed.
2. When X0 = Off, as an ordinary program, the program keeps on executing from address 0. CJ instruction will not
be executed at this time.

CJ instruction
Program Example 2:
1. CJ instruction can be used in the following 5 conditions between MC and MCR instructions.
a) Without MC ~ MCR.
b) From without MC to within MC. Valid in the loop P1 as shown in the figure below.
c) In the same level N, inside of MC~MCR.
d) From within MC to without MCR.
e) Jumping from this MC ~ MCR to another MC ~ MCR1.
2. Actions in ES/EX/SS series models V4.7 (and below): When CJ instruction is used between MC and MCR, it
can only be applied without MC ~ MCR or in the same N layer of MC ~ MCR. Jumping from this MC ~ MCR to
another MC ~ MCR will result in errors, i.e. a) and c) as stated above can ensure correct actions; others will
cause errors.
3. When MC instruction is executed, PLC will push the status of the switch contact into the self-defined stack in
PLC. The stack will be controlled by the PLC, and the user cannot change it. When MCR instruction is executed,
PLC will obtain the previous status of the switch contact from the top layer of the stack. Under the conditions as
stated in b), d) and e), the times of pushing-in and obtaining stack may be different. In this case, the maximum
stack available to be pushed in is 8 and the obtaining of stacks cannot resume once the stack becomes empty.
Thus, when using CALL or CJ instructions, the user has to be aware of the pushing-in and obtaining of stacks.

2. EI instruction allows interrupting subroutine in the program, e.g. external interruption, timed interruption, and
high-speed counter interruption.
3. In the program, using interruption subroutine between EI and DI instruction is allowed. However, you can
choose not to use DI instruction if there is no interruption-disabling section in the program.
4. When M1050 ~ M1059 are the special auxiliary relays to drive disabling interruption in ES/SA, or M1280 ~
M1299 are the special auxiliary relays to drive disabling interruption in EH/EH2/SV, the corresponding
interruptions will not be executed even in the area allowed for interruptions.
5. Pointer for interruption (I) must be placed after FEND instruction.
6. Other interruptions are not allowed during the execution of interruption subroutine.
7. When many interruptions occur, the priority is given to the firstly executed interruption. If several interruptions
occur simultaneously, the priority is given to the interruption with the smaller pointer No.
8. The interruption request occurring between DI and EI instructions that cannot be executed immediately will be
memorized and will be executed in the area allowed for interruption.
9. The time interruptions in ES/SA will not be memorized.
10. When using the interruption pointer, DO NOT repeatedly use the high-speed counter driven by the same X input
contact.
11. When immediate I/O is required during the interruption, write REF instruction in the program to update the status
of I/O.
Program Example:
During the operation of PLC, when the program scans to the area between EI and DI instructions and X1 = Off→On
or X2 = Off→On, interruption subroutine A or B will be executed. When the subroutine executes to IRET, the program
will return to the main program and resumes its execution.

Explanations:
1. This instruction denotes the end of the main program. It has the same function as that of END instruction when
being executed by PLC.
2. CALL must be written after FEND instruction and add SRET instruction in the end of its subroutine. Interruption
program has to be written after FEND instruction and IRET must be added in the end of the service program.
3. If several FEND instructions are in use, place the subroutine and interruption service programs between the
final FEND and END instruction.
4. After CALL instruction is executed, executing FEND before SRET will result in errors in the program.
5. After FOR instruction is executed, executing FEND before NEXT will result in errors in the program.

Explanations:
1. No operand.
2. The watchdog timer in DVP series PLCs is used for monitoring the operation of the PLC system.
3. WDT instruction can be used to reset Watch Dog Timer. If the PLC scan time (from step 0 to END or when
FEND instruction is executed) exceeds 200ms, PLC ERROR LED will flash. The user will have to turn off PLC
and back On again. PLC will determine RUN/STOP status by RUN/STOP switch. If there is no RUN/STOP
switch, PLC will return to STOP status automatically.
4. When to use WDT:
a) When errors occur in the PLC system.
b) When the executing time of the program is too long, resulting in the scan time being larger than the content in
D1000, the user can improve the problem by the following two methods.
Using WDT instruction
t1 t2
STEP0 END(FEND)
WDT
Using the set value in D1000 (default value: 200ms) to change the time for watchdog.
Program Example:
Assume the scan time of the program is 300ms, divide the program into two parts and place WDT instruction in the
middle of the two parts, making scan time of the first half and second half of the program being less than 200ms.
X0

Explanations:
1. No operand. No contact to drive the instruction is required.
2. FOR instruction indicates FOR ~ NEXT loops executing back and forth N times before escaping for the next
execution.
3. N = K1 ~ K32,767. N is regarded as K1 when N ≤ 1.
4. When FOR~NEXT loops are not executed, the user can use the CJ instruction to escape the loops.
5. Error will occur when
a) NEXT instruction is before FOR instruction.
b) FOR instruction exists but NEXT instruction does not exist.
c) There is NEXT instruction after FEND or END instruction.
d) The number of instructions between FOR ~ NEXT differs.
6. FOR~NEXT loops can be nested for maximum five levels. Be careful that if there are too many loops, the
increased PLC scan time may cause timeout of watchdog timer and error. Users can use WDT instruction to
modify this problem.
Program Example 1:
After program A has been executed for 3 times, it will resume its execution after NEXT instruction. Program B will be
executed for 4 times whenever program A is executed once. Therefore, program B will be executed 3 × 4 = 12 times
in total.

S: Source of data m1: Start digit to be moved of the source data m2: Number of digits (nibbles) to be moved of the
source data D: Destination device n: Start digit of the destination position for the moved digits
Explanations:
1. This instruction is able to re-allocate or combine data. When the instruction is executed, m2 digits of contents
starting from digit m1 (from high digit to low digit) of S will be sent to m2 digits starting from digit n (from high digit
to low digit) of D.
2. Range: m1 = 1 ~ 4; m2 = 1 ~ m1; n = m2 ~ 4
3. See the specifications of each model for their range of use.
4. M1168 is designated by SMOV working mode. When M1168 = On, the program is in BIN mode. When M1168 =
Off, the program is in BCD mode.
Program Example 1:
1. When M1168 = Off (in BCD mode) and X0 = On, the 4th (thousand) and 3rd (hundred) digit of the decimal value
in D10 start to move to the 3rd (hundred) and 2nd (ten) digit of the decimal value in D20. 103 and 100 of D20
remain unchanged after this instruction is executed.
2. When the BCD value exceeds the range of 0 ~ 9,999, PLC will determine an operation error and will not execute
the instruction. M1067, M1068 = On and D1067 records the error code OE18 (hex).

3. Flags: M1067 (operation error); M1068 (operation error); D1067 (error code)
4. The content in S (BIN value) is converted into BCD value and stored in D.
5. As a 16-bit (32-bit) instruction, when the conversion result exceeds the range of 0 ~ 9,999 (0 ~ 99,999,999), and
M1067, M1068 = On, D1067 will record the error code 0E18 (hex).
6. The four arithmetic operations and applications in PLC and the execution of INC and DEC instructions are
performed in BIN format. Therefore, if the user needs to see the decimal value display, simply use this
instruction to convert the BIN value into BCD value.
Program Example:
1. When X0 = On, the binary value of D10 will be converted into BCD value, and the 1s digit of the conversion
result will be stored in K1Y0 (Y0 ~ Y3, the 4 bit devices).

6. Provided the content in S is not a BCD value (in hex and any one of its digits does not fall in the range of 0 ~ 9),
an operation error will occur. M1067, M1068 = On and D1067 records the error code 0E18 (hex).
7. Constant K and H will automatically be converted into BIN format. Thus, they do not need to adopt this
instruction.
Program Example:

Remarks:
Explanations on BCD and BIN instructions:
1. When PLC needs to read an external DIP switch in BCD format, BIN instruction has to be first adopted to
convert the read data into BIN value and store the data in PLC.
2. When PLC needs to display its stored data by a 7-segment display in BCD format, BCD instruction has to be
first adopted to convert the data into BCD value and send the data to the 7-segment display.
3. When X0 = On, the BCD value of K4X0 is converted into BIN value and sent it to D100. The BIN value of D100

Operands:
S1: Source data device 1 S2: Source data device 2 D: Operation result
Explanations:
1. If S1, S2 and D are used in device F, only 16-bit instruction is applicable.
2. See the specifications of each model for their range of use.
3. This instruction conducts logical XOR operation of S1 and S2 and stores the result in D.
4. Operation rule: If the bits in S1 and S2 are the same, the corresponding bit of the operation result in D will be “0”;
if the bits in S1 and S2 are different, the corresponding bit of the operation result in D will be “1”.
Program Example 1:
When X0 = On, the 16-bit D0 and D2 will perform WXOR, logical XOR operation, and the result will be stored in D4.

Explanations:
1. Range of n: 2 ~ 512
2. See the specifications of each model for their range of use.
3. Flag: M1020 (zero flag)
4. The stack data of n words starting from S are defined as “first-in, first-out” stack data. After the content in S
minuses 1, the content in the device designated by (S + 1) will be written into the location designated by D, and
(S + n-1) ~ (S + 2) will all right shift for one register while the content in (S + n-1) remains the same. When the
content in S equals 0, this instruction will not process any new value read out and the zero flag M1020 = On.
5. This instruction adopts pulse execution instructions (SFRDP)
Program Example:
1. When X0 = Off→On, the content in D1 will be sent to D21 and D9~D2 will shift to the right for 1 register (content
in D9 remains unchanged) and the content in D0 minus 1.
2. The figure below illustrates the shift and reading in 1~3 execution of the instruction.

3. D will occupy 2 consecutive devices
4. When M1081 is Off, BIN integer is converted into binary floating point value. At this time, S of the 16-bit
instruction, FLT, occupies 1 register and D occupies 2 registers.
a) If the absolute value of the conversion result ＞ max. floating value, carry flag M1022 = On.
b) If the absolute value of the conversion result ＜ min. floating value, carry flag M1021 = On.
c) If the conversion result is 0, zero flag M1020 = On.
5. When M1081 is On, binary floating point value is converted into BIN integer (digits after decimal point are left
out). At this time, S of the 16-bit instruction, FLT, occupies 2 registers and D occupies 1 register (action same as
that of INT instruction).
a) If the conversion result exceeds the range of BIN integer available in D (for 16-bit: -32,768 ~ 32,767; for 32-bit:
-2,147,483,648 ~ 2,147,483,647), D will obtain the maximum or minimum value and carry flag M1022 = On.
b) If any digits is left out during the conversion, borrow flag M1021 = On.
c) If S = 0, zero flag M1020 = On.
d) After the conversion, D stores the result in 16 bits.
Program Example 1:
1. When M1081 = Off, the BIN integer is converted into binary floating point value.
2. When X10 = On, D0 (BIN integer) is converted into D13 and D12 (binary floating point value).
3. When X11 = On, D1 and D0 (BIN integer) are converted into D21 and D20 (binary floating point value).
4. If D0 = K10, X10 will be On. The 32-bit value of the converted floating point will be H41200000 and stored in

Operands:
D: Start device to be I/O refreshed n: Number of items to be I/O refreshed
Explanations:
1. D must designate X0, X10, Y0, Y10…the points whose 1s digit is “0”. See remarks for more details.
2. Range of n: 8 ~ 256 (has to be the multiple of 8).
3. See the specifications of each model for their range of use.
4. The status of all PLC input/output terminals will be updated after the program scans to END. When the
program starts to scan, the status of the external input terminal is read and stored into the memory of the input
point. The output terminal will send the content in the output memory to the output device after END instruction
is executed. Therefore, this instruction is applicable when the latest input/output data are needed for the
operation.
5. D has to be designated to be X0, X10, Y0, Y10…such forms whose 1st digit is “0”. Range of n: 8 ~ 256 (must
be 8’s multiple); otherwise it will be regarded as an error. The range varies in different models. See Remarks
for more details.
Program Example 1:
When X0 = On, PLC will read the status of input points X0 ~ X17 immediately and refresh the input signals without
any input delay.

Operands:
n: Response time (unit: ms)
Explanation:
1. Range of n: for SA/SX/SC, n = K0 ~ K20; for EH/EH2/SV/EH3/SV2, n = K0 ~ K60.
2. To avoid interferences, X0 ~ X17 of EH/EH2/SV/EH3/SV2 series MPU and X0 ~ X7 of SA/SX/SC series MPU
are equipped with digital filters on output terminals. Digital filters adjust the response time by REFF instruction.
This instruction sets up n directly in D1020 (adjusting the response time of X0 ~ X7) and D1021 (adjusting the
response time of X10 ~ X17).
3. Rules for adjusting the reponse time of the filter at X0 ~ X17:
a) When the power of PLC turns from Off to On or the END instruction is being executed, the response time
will be determined upon the contents in D1020 and D1021.
b) You can use MOV instruction in the program to move the time values to D1020 and D1021 and make
adjustments in the next scan.
c) You can use REFF instruction to change the response time during the execution of the program. The
changed response time will be move to D1020 and D1021 and you can make adjustments in the next scan.
Program Example:
1. When the power of PLC turns from Off to On, the response
time of X0 ~ X17 will be determined by the contents in D1020
and D1021.
2. When X20 = On, REFF K5 will be executed and the response
time will be changed to 5ms for the adjustment in the next
scan.
3. When X20 = Off, the REFF K20 will be executed and the
response time will be changed to 20ms for the adjustment in
the next scan.

Operands:
S: Start device of matrix input D1: Start device of matrix output D2: Corresponding start device for matrix scan
n: Number of arrays in matrix scan
Explanations:
1. S must designate X0, X10…the X points whose 1st digit is “0” and occupies 8 consecutive points.
2. D1 must designate Y0, Y10…the Y points whose 1st digit is “0” and occupies n consecutive points.
3. D2 must designate Y0, M0. S0…the Y, M, S points whose 1st digit is “0”.
4. Range of n: 2 ~ 8.
5. See the specifications of each model for their range of use.
6. Flag: M1029 (execution of the instruction is completed).
7. S is the start device No. of all input terminals connected to the matrix. Once S is designated, the 8 points
following the No. will be the input terminals in the matrix.
8. D1 designate the start device No. of transistor output Y in the matrix scan.
9. This instruction occupies continuous 8 input devices starting from S. n external output terminals starting from
D1 read the 8 switches of n arrays by matrix scan, obtaining 8 × n multiple-matrix input points. The status of
scanned switches will be stored in the devices starting from D2.
10. Maximum 8 input switches can be parallelly connected in 8 arrays and obtaining 64 input points (8 × 8 = 64).
11. When the 8-point 8-array matrix inputs are in use, the reading time of each array is approximately 25ms,
totaling the reading of 8 arrays 200ms, i.e. the input signals with On/Off speed of over 200ms are not
applicable in a matrix input.
12. The drive contact of this instruction uses normally On contact M1000.
13. Whenever this instruction finishes a matrix scan, M1029 will be On for one scan period.
14. There is no limitation on the number of times using the instruction, but only one instruction can be executed in
a period of time.
Program Example:
1. When PLC RUN, MRT instruction will start to be executed. The statuses of the external 2 arrays of 16 switches
will be read in order and stored in the internal relays M10 ~ M17, M20 ~ M27.

Operands:
S1: Comparative value S2: No. of high speed counter D: Comparison result
Explanations:
1. S2 has to designate the No. of high speed counters C235 ~ C255. See remarks for more details.
2. D can designate I0□0; □ = 1 ~ 6. ES series MPU does not support this.
3. D of ES and SA series MPU does not support E, F index register modification.
4. See the specifications of each model for their range of use.
5. Flags: M1289 ~ M1294 are interruption disability of the high speed counters in EH/EH2/SV/EH3/SV2 series
MPU. See Program Example 3 for more details.
6. The high speed counter inputs counting pulses from the corresponding external input terminals X0 ~ X17 by
inserting an interruption. When the high speed counter designated in S2 pluses 1 or minuses 1, DHSCS
instruction will perform a comparison immediately. When the present value in the high speed counter equals
the comparative value designated in S1, device designated in D will turn On. Even the afterward comparison
results are unequal, the device will still be On.
7. If the devices specified as the device D are Y0 ~ Y17, when the compare value and the present value of the
high-speed counter are equal, the comparison result will immediately output to the external inputs Y0 ~ Y17,
and other Y devices will be affected by the scan cycle. However, M, S devices are immediate output and will
not be affected by the scan cycle.
Program Example 1:
After PLC RUN and M0 = On, DHSCS instruction will be executed. When the present value in C235 changes from
99 to 100 or 101 to 100, Y10 will be On constantly.

Differences between Y output of DHSCS instruction and general Y output:
a) When the present value in C249 changes from 99 to 100 or 101 to 100, Y10 outputs immediately to the external
output point by interruption and has nothing to do with the PLC scan time. However, the time will still be delayed
by the relay (10ms) or transistor (10us) of the output module.

b) When the present value in C249 changes from 99 to 100, the drive contact of C249 will be On immediately. When
the execution arrives at SET Y17, Y17 will still be affected by the scan time and will output after END instruction.

Program Example 3:
1. High speed counter interruption:
a) Operand D of DHSCS instruction can designate I0□0, □ = 1 ~ 6, as the timing of interruption when the
counting reaches its target.
b) ES/EX/SS series MPU does not support high speed counter interruption.
c) SA/SX/SC series MPU supports high speed counter interruption. However, when DHSCS instruction
designates an I interruption, the designated high speed counter cannot be used in DHSCS, DHSCR, DHSZ
instructions. Misuse of high speed counter will result in error.
d) For SA/SX/SC series MPU, when the counting reaches the target, the interruption will occur. X0 is the
counter for counting input and the interruption No. is I010 (1 phase 2 inputs and A-B phase counter No. C246
~ C254 can only designate I010). X1 designates I020; X2 designates I030; X3 designates I040; X4
designates I050; X5 designates I060, totaling 6 points.
e) When the present value in C251 changes from 99 to 100 or 101 to 100, the program will jump to I010 and
execute the interruption service subroutine.

Remarks:
1. The output contact of the high speed counter and the comparative outputs of API 53 DHSCS, API 34 DHSCR
and API 55 DHSZ instructions only perform comparison and contact outputs when there is a counting input.
When using data operation instructions, e.g. DADD, DMOV, for changing the present value in the high speed
counter or making the present value equals the set value, there will not be comparisons or comparative
outputs because there is no counting inputs.

a) Input points X0 and X1 can be planned as counters of higher speed (1 phase input can reach 20kHz).
However, the total counting frequency of the two input points has to be smaller or equal 20kHz. Provided
the input is a 2-phas input signal, the counting frequency will be approximately 4kHz. The frequency of
the input points X2 and X3 (1-phase) can reach 10kHz.
b) For ES/EX/SS series MPU, the uses of DHSCS instructio with DHSCR instruction cannot be more than 4
times.

2-phase input (X0, X1) C251, C252 and C254 can reach a frequency of 4kHz and C253 reach 25kHz
(only supports 4 times frequency counting).
b) Functions of the input point X5:
i) When M1260 = Off, C240 is the general U/D high speed counuter.
ii) When M1260 = On and C240 is enabled by DCNT instruction, X5 will be the shared reset signal for
C235 ~ C239. The counter C240 will still receive the counting input signals from X5.

MPU.
b) The input points of 1-phase input X10 (C243), X11 (C245) and (X10, X11) C250 can reach a frequency of
100kHz. The total bandwidth of X10 ~ X11 is 130kHz. C255 of the 2-phase input (X10, X11) can reach a
frequency of 50kHz.
c) For SA/SX/SC series MPU, the uses of DHSCS instruction with DHSCR instruction cannot be more than 6
times and the uses of DHSZ instruction cannot be more than 6 times as well. When DHSCR instruction
designates I interruption, the designated high speed counter cannot be used in other DHSCS, DHSCR
and DHSZ instructions.
d) The functions of X10 ~ X11 high speed counters in SC series MPU:
i) When X10 and X11 are set as 1-phase 1 input or 1-phase 2 inputs. The maximum frequency of a
single phase can reach 100kHz. When they are set as 2-phase 2 inputs, the maximum frequency can
reach 50kHz.
ii) X10 and X11 can select rising-edge counting mode or falling-edge counting mode. X10 is set by
D1166 and X11 is set by D1167. K0: rising-edge counting. K1: falling-edge counting. K2: rising/falling
edge counting (only supports X10).
iii) The counting up and down of C243 are determined by the On/Off of M1243. The counting up and
down of C245 are determined by the On/Off of M1245. Rising-edge and falling-edge counting are not
able to take place at the same time. The rising-edge trigger and falling-edge trigger of C250 are
determined by the content (K0 or K1) of D1166. C255 can only be used in a 4 times frequency
counting and you can only select rising-edge trigger.
iv) When C243 or C245 is in use, you will not be able to use C250 or C255, and vice versa.

vi) Explanations on high speed counter and high speed comparator:
(1) When DHSCS and DHSCR instructions use the high speed counter (C243/C245/C250/C255),
they can only use the set values of 2 groups of high speed comparative instructions. Assume that
a group of comparative instruction DHSCS D0 C243 Y10 is already in use, you can only set
another group DHSCR D2 C243 Y10 or DHSCS D4 C245 Y10.
(2) When DHSZ instruction use the high speed counter (C243/C245/C250/C255), it can only use the
set value of a group of comparators.
(3) The number of set values in a high-speed comparative instruction offered in SA/SX series MPU
will not decrease becasus of the addition of the new high speed counters.
(4) If the high-speed comparative instruction DHSCS requires a high-speed reponse output, it is
suggested that you use Y10 or Y11 for the output. If you use other general devices for the output,
there will be delay of 1 scan period. For example, when in I0x0 interruption, C234 will correspond
to I020, C245 to I040 and C250/C255 to I060.
(5) The high-speed comparative instruction DHSCR can clear output devices and counter devices,
but only the counters used by the same instruction, e.g. DHSCR K10 C243 C243. This function
can only applied in the four special high speed counters C243, C245, C250 and C255.
e) Counting modes:
i) The 2-phase 2 inputs counting mode of the high speed counters in ES/EX/SS (V5.5 and above) and
SA/SX/SC series MPU is set by special D1022 with normal frequency, double frequency and 4 times
frequency modes. The contents in D1022 will be loaded in in the first scan when PLC is switched from
STOP to RUN.

5. EH/EH2/SV/EH3/SV2 series MPU supports high speed counters. C235 ~ C240 are program-interruption
1-phase high speed counter with a total bandwidth of 20kHz, can be used alone with a counting frequency of
up to 10kHz. C241 ~ C254 are hardware high speed counter (HHSC). There are four HHSC in
EH/EH2/SV/EH3/SV2 series MPU, HHSC0 ~ 3. The pulse input frequency of HHSC0 and HHSC1 can reach
200kHz and that of HHSC2 and HHSC3 can reach 20kHz (1 phase or A-B phase). The pulse input frequency of
HHSC0 ~ 3 of 40EH2 series MPU can reach 200kHz, among which:
C241, C246 and C251 share HHSC0
C242, C247 and C252 share HHSC1
C243, C248 and C253 share HHSC2
C244, C249 and C254 share HHSC3
a) Every HHSC can only be designated to one counter by DCNT instruction.
b) There are three counting modes in every HHSC (see the table below):
i) 1-phase 1 input refers to “pulse/direction” mode.
ii) 1-phase 2 inputs refers to “clockwise/counterclockwise (CW/CCW)” mode.
iii) 2-phase 2 inputs refers to “A-B phase” mode.

c) In EH/EH2/SV/EH3/SV2 series MPU, there is no limitation on the times of using the hardware high speed
counter related instructions, DHSCS, DHSCR and DHSZ. However, when these instructions are enabled
at the same time, there will be some limitations. DHSCS instruction will occupy 1 group of settings,
DHSCR 1 group of settings and DHSZ 2 groups of settings. There three instructions cannot occupy 8
groups of settings in total; otherwise the system will ignore the instructions which are not the first scanned
and enabled.
d) System structure of the hardware high speed counters:
i) HHSC0 ~ 3 have reset signals and start signals from external inputs. Settings in M1272, M1274,
M1276 and M1278 are reset signals of HHSC0, HHSC1, HHSC2 and HHSC3. Settings in M1273,
M1275, M1277 and M1279 are start signals of HHSC0, HHSC1, HHSC2 and HHSC3.
ii) If the external control signal inputs of R and S are not in use, you can set M1264/M1266/M1268/M1270
and M1265/M1267/M1269/M1271 as True and disable the input signals. The corresponding external
inputs can be used again as general input points (see the figure below).
iii) When special M is used as a high speed counter, the inputs controlled by START and RESET will be
affected by the scan time.

Operands:
S1: Comparative value S2: No. of high speed counter D: Comparison result
Explanations:
1. S2 has to designate the No. of high speed counters C235 ~ C255. See remarks of API 53 DHSCS for more
details.
2. D of EH/EH2/SV series MPU can designate the No. of high speed counters C241 ~ C254 that are the same as
the counters designated by S2.
3. D of SC series MPU can designate the No. of high speed counters C243, C245, C248, C250 and C255 that
are the same as the counters designated by S2.
4. D of ES/EX/SS/SA/SX series MPU does not support device C.
5. See the specifications of each model for their range of use.
6. Flags: M1150 ~ M1333; see remarks of API 53 DHSCS for more details. ES/EX/SS/SA/SX/SC series MPU
does not support M1261 (high speed counter external reset mode designation); see remarks for more details.
7. The high speed counter inputs counting pulses from the corresponding external input terminals X0 ~ X17 by
inserting an interruption. When the No. of high-speed counter designated in S2 “+1“ or “-1”, DHSCR will
perform a comparison immediately. When the present value in the high speed counter equals the comparative
value designated in S1, the device designated in D will turn Off and even the afterward comparison results are
unequal, the device will still be Off.
8. If the devices designated in D are Y0 ~ Y17, when the comparative value equals the present value in the high
speed counter, the comparison result will immediately output to the external output terminals Y0 ~ Y17 (and
clear the designated Y output) and the rest of Y devices will be affected by the scan cycle. Devices M and S
act immediately without being affected by the scan cycle.
Program Example 1:
1. When M0 = On and the present value in the high speed counter C251 changes from 99 to 100 or 101 to 100,
Y10 will be cleared and Off.
2. When the present value in the high speed counter C251 changes from 199 to 200, the contact of C251 will be
On and make Y0 = On. However, the program scan time will delay the output.
3. Y10 will immediately reset the status when the counting reaches its target. D is also able to designate high
speed counters of the same No. See Program Example 2.

Remarks:
1. DVP all series MPU support high speec counters. For the limitation on the use of instructions, see remarks of
API 53 DHSCS for more details.
2. M1261 of EH/EH2/SV/EH3/SV2 series MPU designates the external reset modes of the high speed counter.
Some high speec counters have input points for external reset; therefore, when the input point is On, the
present value in the corresponding high speed counter will be cleared to 0 and the output contact will be Off. If
you wish the reset to be executed immediately by the external output, you have to set M1261 to be On.
3. M1261 can only be used in the hardware high speed counter C241 ~ C255.
4. Example:
a) X2 is the input point for external reset of C251.
b) Assume Y10 = On.
c) When M1261 = Off and X2 = On, the present value in C251 will be cleared to 0 and the contact of C251 will
be Off. When DHSCR instruction is executed, there will be no counting input and the comparison result will
not output. The external output will not execute the reset; therefore Y10 = On will remain unchanged.
d) When M1261 = On and X2 = On, the present value in C251 will be cleared to 0 and the contact of C251 will
be Off. When DHSCR instruction is executed, there will be no counting input but the comparison result will
output. Therefore, Y10 will be reset.

Explanations:
1. S1 has to be euqal to or smaller than S2. (S1 ≤ S2)
2. When S1 > S2, the instruction will perform a comparison by using S1 as the upper bound and S2 as the lower
bound.
3. S has to designate high speed counters C235 ~ C255, See remarks of API 53 DHSCS for more details.
4. D will occupy 3 consecutive devices.
5. Flags: M1150 ~ M1333; see remarks of API 53 DHSCS for more details. M1150, M1151 DHSZ executing

6. The output will not be affected by the scan time.
7. The zone comparisons and outputs are all processed by inserting interruptions.
Program Example 1:
1. Designate device Y0 and Y0 ~ Y2 will be automatically occupied.

Program Example 2:
1. Use DHSZ instruction for high/low speed stop control. C251 is an A-B phase high speed counter and DHSZ only
performs comparison output when there is a C251 counting pulse input. Therefore, even when the present value
in the counter is 0, Y10 will not be On.
2. When X10 = On, DHSZ will require that Y10 has to be On when the present value in the counter ≤ K2,000. To
solve this requirement, you can execute DZCPP instruction when the program was first RUN and compare
C251 with K2,000. When the present value in the counter ≤ K2,000, Y10 will be On. DZCPP instruction is a
pulse execution instruction and will only be executed once with Y10 being kept On.
3. When the drive contact X10 = Off, Y10 ~ Y12 will be reset to Off.

3. In this mode,
- S1: start device in the comparison table. S1 can only designate data register D and can be modified by E and
F. Once this mode is enabled, S1 will not be changed even the E and F has been changed.
- S2: number of group data to be compared. S2 can only designate K1 ~ K255 or H1 ~ HFF and can be
modified by E and F. Once this mode is enabled, S2 cannot be changed. If S2 is not within its range, error
code 01EA (hex) will display and the instruction will not be executed.
- S: No. of high speed counter (designated as C241 ~ C254).
- D: Designated mode (can only be M1150)
4. The No. of start register designated in S1 and the number of rows (groups) designated in S2 construct a
comparison table. Please enter the set values in every register in the table before executing the instruction.
5. When the present value in the counter C251 designated in S equals the set values in D1 and D0, the Y output
designated by D2 will be reset to Off (D3 = K0) or On (D3 = K1) and be kept. Output Y will be processed as an
interruption. No. of Y output pointss are in decimal (range: 0 ~ 255). If the No. falls without the range,
SET/RESET will not be enabled when the comparison reaches its target.
6. When this mode is enabled, PLC will first acquire the set values in D0 and D1 as the target value for the first
comparison section. At the same time, the index value displayed in D1150 will be 0, indicating that PLC
performs the comparison based on the group 0 data.
7. When the group 0 data in the table have been compared, PLC will first execute the Y output set in group 0 data
and determine if the comparison reaches the target number of groups. If the comparison reaches the target,
M1151 will be On; if the comparison has not reached the final group, the content in D1150 will plus 1 and
continue the comprison for the next group.
8. M1151 is the flag for the completion of one execution of the table, can be Off by the user. Or when the next
comparion cycle takes place and the group 0 data has been compared, PLC will automatically reset the flag.
9. When the drive contact of the instruction X10 goes Off, the execution of the instruction will be interrupted and
the content in D1150 (table counting register) will be reset to 0. However, the On/Off status of all outputs will be
remained.
10. When the instruction is being executed, all set values in the comparison table will be regarded as valid values
only when the scan arrives at END instruction for the first time.
11. This mode can only be used once in the program.
12. This mode can only be used on the hardware high speed counters C241 ~ C254.
13. When in this mode, the frequency of the input counting pulses cannot exceed 50kHz or the neighboring two
groups of comparative values cannot differ by 1; otherwise there will not be enough time for the PLC to react
and result in errors.

performs the comparison based on the group 0 data.
6. When the group 0 data in the table have been compared, PLC will first execute at the frequency set in group 0
data (D2, D3) and copy the data to D1152 and D1153, determining if the comparison reaches the target number
of groups. If the comparison reaches the target, M1153 will be On; if the comparison has not reached the final
group, the content in D1151 will plus 1 and continue the comprison for the next group.
7. M1153 is the flag for the completion of one execution of the table, can be Off by the user. Or when the next

Operands:
S1: External pulse input terminal S2: Pulse receiving time (ms) D: Detected result
Explanations:
1. See the specifications of each model for their range of use.
2. Flag: M1100 (SPD instruction performs sampling for one time)
3. External pulse input terminals designated in S1 for all series MPU:
MPU
Input
ES/EX/SS
(V5.7and above) SA/SX/SC EH EH2/SV/EH3/SV2
Available input points X1, X2 X0 / X1,
X1, X2 X0, X1, X2, X3 X0 / X1,
X1, X2, X3
4. For SA/SX (V1.4 and above) series MPU and SC (V1.2 and above) series MPU, the new X0 and X1 can be
used together with A-B phase input points. When “A ahead of B” detection result is a positive value and “B
ahead of A” detection result is a negative value, the multiplied frequency of the counter can be set by D1022.
5. Input points on EH series are single-phase input. EH2/SV/EH3/SV2 series support A-B phase input, and X0 has
to be designated in the instruction as the speed detection point and X1 occupied. When B is ahead of A, the
detection result will be positive value. If A is ahead of B, the detection result will be negative value.
6. The received number of pulses of the input terminal designated in S1 is calculated within the time (in ms)
designated in S2. The result is stored in the register designated in D.
7. D will occupy 5 consecutive devices. D + 1 and D are the detected value obtained from the previous pulses; D
+3 and D + 2 are the current accumulated number of values; D + 4 is the counting time remaining (max.
32,767ms).
8. Pulse frequency detection for all series:

t: Detecting time designated in S2 (ms)
10. The X input point designated by this instruction cannot be used again as the pulse input terminal of the high
speed counter or as an external interruption signal.
11. When M1036 in SC (V1.4 and above) series MPU is enabled, SPD instruction can detect the speeds at X0 ~ X5
at the same time with a total bandwidth of 40kHz. See 2.11 for more details for how to use M1036.
12. There is no limitation on the times of using this instruction in the program, but only one instruction will be
executed at a time.
13. When SPD instruction is enabled and M1100 = On, SPD instruction will perform a sampling at the moment when
M1100 goes from Off to On and stop the sampling. If you wish to resume the sampling, you have to turn Off
M1100 and re-enable SPD instruction.
Program Example:
1. When X7 = On, D2 will calculate the high-speed pulses input by X1 and stop the calculation automatically after
1,000ms. The result will be stored in D0.
2. When the 1,000ms counting is completed, D2 will be cleared to 0. When X7 is On again, D2 will start the
calculation again.

Remarks:
1. When ES/EX/SS (V5.7 and above) and SA/SX/SC series MPU use X1 or X2, the relevant high speed counters
or external interruptions I101 and I201 cannot be used.
2. For SC (V1.4 and above) series MPU, when M1036 is enabled, the speed of X0 ~ X5 can be detected at the
same time.

Operands:
S1: Pulse output frequency S2: Number of output pulses D: Pulse output device (please use transistor output
module)
Explanations:
1. The program of ES/EX/SS series MPU can use PLSY instruction two times but cannot designate the same Y
device.
2. Flags: M1010 ~ M1345. See remarks for more details.
3. S1 designates the pulse output frequency. With M1133 ~ M1135 and D1133, Y0 of SA/SX series MPU is able to
output pulses at 50kHz. SV/EH2/EH3/SV2 series MPU of V1.4 and later versions use M1190 ~ M1191, and Y0
and Y2 are able to output 0.01 ~ 500Hz.
Range of output frequency for all series:
MPU ES/EX/SS SA/SX SC EH EH2/SV/EH3/SV2
Frequency range Y0: 0 ~10kHz
Y1: 0 ~10kHz
Y0: 0 ~ 32kHz
Y1: 0 ~10kHz
Y0: 0 ~ 30kHz
Y1: 0 ~ 30kHz
Y10: 77 ~ 100kHz
Y11: 77 ~ 100kHz
Y0: 1 ~ 200kHz
Y2: 1 ~ 200kHz
Y0: 0 ~ 200kHz
Y2: 0 ~ 200kHz
Y4: 0 ~ 200kHz
Y6: 0 ~ 200kHz
4. S2 designates the number of output pulses. The 16-bit instruction can designate 1 ~ 32,767 pulses and the
32-bit instruction can designate 1 ~ 2,147,483,647 pulses.
Number of continuous pulses for all series:
MPU ES/EX/SS/SA/SX/SC SC EH/EH2/SV/EH3/SV2
How to designate
continuous pulses
M1010 (Y0) On
M1023 (Y1) On
M1010 (Y0) On
M1023 (Y1) On
The number of output pulses designated
for Y10 and Y11 is set to K0.
The number of output
pulses designated for
Y0, Y2, Y4 and Y6 is set
to K0
5. For EH/EH2/SV/EH3/SV2 series MPU, when the number of output pulses is set to 0, there will be continuous
pulse output with no limitation on the number of pulses. For ES/EX/SS/SA/SX/SC series MPU, you have to
make M1010 (Y0) or M1023 (Y1) On to allow a continuous pulse output with no limitation on the number of
pulses.
7 Application Instructions API 50-99
DVP-PLC APPLICATION MANUAL
7-27
6. For the pulse output device designated in D, EH series MPU can designate Y0 and Y2, EH2/SV/EH3/SV2 series
MPU can designate Y0, Y2, Y4 and Y6, ES/EX/SS/SA/SX series MPU can designate Y0 and Y1, SC series
MPU can designate Y0, Y1, Y10 and Y11. (SC V1.2 and above series MPU supports Y10 and Y11).
7. EH series MPU has two groups of A-B phase pulse output from CH0 (Y0, Y1) and CH1 (Y2, Y3);
EH2/SV/EH3/SV2 series MPU has four groups of A-B phase pulse output from CH0 (Y0, Y1), CH1 (Y2, Y3),
CH2 (Y4, Y5) and CH3 (Y6, Y7). See 2.3 and remarks for how to set up.
8. When PLSY instruction is executed, it will designate the number of output pulses (S2) output from the output
device (D) at a pulse output frequency (S1).
9. When PLSY instruction is used in the program, its outputs cannot be the same as those in API 58 PWM and API
59 PLSR.
10. Pulse output completed flags for all series:
MPU ES/EX/SS
SA/SX/SC SC EH/EH2/SV EH2/SV/EH3/SV2
Output device Y0 Y1 Y10 Y11 Y0 Y2 Y4 Y6
Flag M1029 M1030 M1102 M1103 M1029 M1030 M1036 M1037
11. For ES/EX/SS/SA/SX/SC/EH series MPU, when PLSY and DPLSY instruction is disabled, the pulse output
completed flags will all be Off automatically.
12. For EH2/SV/EH3/SV2 series MPU, when PLSY and DPLSY instruction is disabled, the user will have to reset
the pulse output completed flags.
13. The user has to reset the pulse output completed flags after the pulse output is completed.
14. After PLSY instruction starts to be executed, Y will start a pulse output. Modifying S2 at this moment will not
affect the current output. If you wish to modify the number of output pulses, you have to first stop the execution
of PLSY instruction and modify the number.
15. S1 can be modified when the program executes to PLSY instruction.
16. Off time : On time of the pulse output = 1 : 1.
17. When the program executes to PLSY instruction, the current number of output pulses will be stored in the
special data registers D1336 ~ D1339. See remarks for more details.
18. For SA/EH series MPU, there is no limitation on the times using this instruction. For SA/SX/SC/EH series MPU,
the program allows two instructions being executed at the same time. For EH2/SV/EH3/SV2 series MPU, the
program allows four instructions being executed at the same time.
Program Example:
1. When X0 = On, there will be 200 pulses output from Y0 at 1kHz. When the pulse output is completed, M1029
will be On and Y10 will be On.
2. When X0 = Off, the pulse output from Y0 will stop immediately. When X0 is On again, the output will start again
ffrom the first pulse.

4. When there are many high speed output instructions (PLSY, PWM, PLSR) for Y0 output in a program, PLC will
only execute the settings and outputs of the instruction that is first enabled.
5. More explanations on M1347 and M1348:
If M1347 and M1348 is enabled, and when the execution of PLSY instruction has been completed, M1347/M1348
will be reset automatically, i.e. you do not have to turn the status of the drive contact from Off to On before PLSY
instruction and when PLC scans to the instruction (assume the drive contact of the instruction is True), there will
still be pulse output. PLC detects the status of M1347 and M1348 when END instruction is being executed.
Therefore, when the pulse output is completed and if PLSY instruction is a continuous execution one, there will be
a scan time of delay in the next string of pulse output.

SET M1347
M1000
DPLSY K1000 K1000 Y2

IRET
SET M1348
END
Explanations:
a) Whenever X0 is triggered, Y0 will output 1,000 pulses; whenever X1 is triggered, Y2 will output 1,000 pulses.
b) When X triggers Y pulse output, there should be an interval of at least one scan time between the end of Y
pulse output and the next X-triggered output.

When both X1 and X2 are On, Y0 pulse output will keep operating. However, there will be a short pause (approx.
1 scan time) every 1,000 pulses before the output of the next 1,000 pulses.

Explanations:
1. S1 ≤ S2.
2. See the specifications of each model for their range of use.
3. In ES/EX/SS series MPU, PWM instruction can only be used once in the program.
4. Flags: See remarks for more details.
5. Range of S1: (t) 0 ~ 32,767ms.
6. Range of S2: (T) 1 ~ 32,767ms (but S1 ≤ S2).
7. D for all series MPU:
MPU ES/EX/SS/SA/SX/SC EH EH2/SV/EH3/SV2

8. When PWM instruction is used in the program, its outputs cannot be the same as those of API 57 PLSY and API
59 PLSR.
9. PWM instruction designates the pulse output width in S1 and pulse output period in S2 and outputs from output
device D.
10. For SA/SX/SC series MPU, When, S1 ≤ 0 or S2 ≤ 0 or S1 > S2, there will be operational errors (M1067 and
M1068 will not be On), and there will be no output from the pulse output device. When S1 = S2, the pulse output
device will keep being On.
11. For EH/EH2/SV/EH3/SV2 series MPU, When, S1 < 0 or S2 ≤ 0 or S1 > S2, there will be operational errors (M1067
and M1068 will be On), and there will be no output from the pulse output device. When S1 = 0, M1067 and
M1068 will not be On and there will be no output from the pulse output device. When S1 = S2, the the pulse
output device will keep being On.
12. S1 and S2 can be changed when PWM instruction is being executed.
13. For SA/EH series MPU, there is no limitation on the times using this instruction in the program. However, for EH
series MPU, two instructions are allowed to be executed at the same time; for EH2/SV/EH3/SV2 series MPU,
four instructions are allowed to be executed at the same time.

Operands:
S1: Maximum speed of pulse output S2: Total number of output pulses S3: Acceleration/deceleration time (ms)
D: Pulse output device (please use transistor output module)
Explanations:
1. See the specifications of each model for their range of use.
2. For ES/EX/SS series MPU, PLSR instruction can be used twice in the program but the outputs cannot be
overlapped.
3. Flags: See remarks of API 57 PLSY.
4. Range of S1: 10 ~ 32,767Hz (16-bit); 10 ~ 200,000Hz (32-bit). The maximum speed has to be 10’s multiple; if
not, the 1s digit will be left out. 1/10 of the maximum speed is the variation of one acceleration or deleration.
Please be aware if the variation reponds to the acceleration/deceleration demand from the step motor, in case
the step motor may crash.
5. Range of S2: 110 ~ 32,767 (16-bit); 110 ~ 2,147,483,647 (32-bit). If S2 is less than 110, the pulet output will be
abnormal.
6. Range of S3: below 5,000ms. The acceleration time and deceleration time have to be the same.
a) The acceleration/deceleration time has to be 10 times longer than the maximum scan time (D1012). If not,
the slope of accleration and deceleration will be incorrect.
b) The minimum set value of acceleration/deceleration time can be obtained from the following equation:
90,000
>
S
3
S
1
If the set value is less than the result obtained from the equation, the acceleration/deceleration time will be
longer. If the set value is less than 90,000/S1, use the result of 90,000/S1 as the set value.
c) The maximum set value of acceleration/deceleration time can be obtained from the following equation:

d) The speed variation is fixed to 10 steps. If the input acceleration/deceleration time is longer than the
maximum set value, the acceleration/deceleration time will follow the maximum set time. If shorter than the
minimum set value, the accleration/deceleration time will follow the minimum set time.

7. D for all series MPU:
MPU ES/EX/SS/SA/SX/SC EH EH2/SV/EH3/SV2
Output point Y0, Y1 Y0, Y2 Y0, Y2, Y4, Y6
8. EH series MPU has two groups pf A-B phase pulse output CH0 (Y0, Y1) and CH1 (Y2, Y3). EH2/SV/EH3/SV2
series MPU has four groups pf A-B phase pulse output CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4, Y5) and CH3 (Y6,
Y7). See remarks of API 57 PLSY for how to set up.
9. PLSR instruction is a pulse output instruction with acclerating and decelerating functions. The pulses accelerate
from the static status to target speed and decelerates when the target distance is nearly reached. The pulse
output will stop when the target distance is reached.
10. When PLSR instruction is executed, after S1, S2 and S3 are set, the pulses will output from D. The output starts
at the frequency of increasing S1/10 at a time. The time forf every frequency is fixed at S3/9.
11. S1, S2 and S3 can be changed when PLSR instruction is being executed.
12. For ES/EX/SS/SA/SX/SC series MPU, when all the Y0 pulses have been sent, M1029 will be On; when all the
Y1 pulses have been sent, M1030 will be On. Next time when PLSR instruction is enabled, M1029 or M1030 will
be 0 again and after the pulse output is completed, it will become 1 again.
13. For EH/EH2/SV/EH3/SV2 series MPU, when all the CH0 (Y0, Y1) pulses have been sent, M1029 will be On;
when all the CH1 (Y2, Y3) pulses have been sent, M1030 will be On; when CH2 (Y4, Y5) pulses have been sent,
M1036 will be On; when CH3 (Y6, Y7) pulses have been sent, M1037 will be On. Next time when PLSR
instruction is enabled, M1029, M1030, M1036 or M1037 will be 0 again and after the pulse output is completed,
they will become 1 again.
14. For EH2/SV/EH3/SV2 series MPU V1.4 and later versions, when the instruction designate incorrect parameters,
the default output will become the maximum value or mininum value.
15. During every acceleration section, the number of pulses ( frequency × time) may not all be integers. PLC will
round up the number to an integer before the output. Therefore, the acceleration time of every section may not
be exactly the same. The offset is determined upon the frequency and the decimal after rounding up. In order to
ensure the correct number of output pulses, PLC will supplement insufficient pulses in the last section.
16. For SA/EH series MPU, there is no limitation on the times of using this instruction in the program. However, for
SA/SX/SC/EH series MPU, two instructions can be exeucted at the same time; for EH2/SV/EH3/SV2 series
MPU, four instructions can be executed at the same time.
Program Example:
1. When X0 = On, the pulses will output at the maximum frequency 1,000Hz with the total number D10 at 3,000ms
from Y0. The frequency will increase by 1,000/10Hz at a time and every frequency will last for 3,000/9 (ms).
2. When X10 is Off, the output will be interrupted. When X0 is On again, the counting of pulses will start from 0.

2. When there are many high speed pulse output instructions (PLSY, PWM, PLSR) in a program for Y0 output, and
provided these instructions are being executed in the same scan period, PLC will set up and output the
instructions with the fewest steps.
3. With M1133 ~ M1135 and D1133, Y0 of SA/SX/SC series MPU can output pulses at up to 50kHz. See 2.11 for

3. See the specifications of each model for their range of use.
4. ES/SA series MPU does not support E, F index register modification.
5. IST instruction can only be used once in the program.
6. Flags: M1040 ~ M1047. See remarks for more details.
7. IST instruction is a handy instruction specifically for the initial status of step ladder control procedure to
accommodate special auxiliary relay.
Program Example 1:
1. Use of IST instruction
M1000
IST X10 S20 S60
S X10: Individual operation
X11: Zero return
X12: Step operation
X13: One cycle operation
X14: Continuous operation
X15: Zero return enabled switch
X16: Start switch
X17: Stop switch
2. When IST instruction is being executed, the following special auxiliary relays will switch automatically.
M1040: Operation forbidden
M1041: Operation starts
M1042: Pulse output enabled
M1047: STL monitor enabled
S0: Initiates manual operation
S1: Initiates zero return
S2: Initiates auto operation
3. S10 ~ S19 are for zero return and cannot be used as general steps. When S0 ~ S9 are in use, S0 ~ S2 represent
manual operation mode, zero return mode and auto operation mode. Therefore, in the program , you have to
write the circuit of the three steps in advance.
4. When switched to S1 (zero return) mode, any On in S10 ~ S19 will result in no zero return.
5. When switched to S2 (auto operation) mode, any On of the S in D1 ~ D2 or M1043 = On will result in no auto

Operands:
S1: Start device in the data table S2: No. of counter D: Start No. of the devices for the comparison results
n: Number of data for comparison
Explanations:
1. When S1 designates KnX, KnY, KnM and KnS, the 16-bit instruction has to designate K4 and 32-bit instruction
has to designate K8.
2. For SA/SX/SC series MPU, S2 only supports C device.
3. Range of n: 1 ~ 64
4. See the specifications of each model for their range of use.
5. ABSD instruction is for the absolute control of the multiple output pulses generated by the present value in the
counter.
6. S2 of DABSD instruction can designate high speed counters. However, when the present value in the high
speed counter is compared with the target value, the result cannot output immediately owing to the scan time. If
an immediate output is required, please use DHSZ instruction that is exclusively for high speed counters.
Program Example:
1. Before the execution of ABSD instruction, use MOV instruction to write all the set values into D100 ~ D107 in
advance. The even-number D is for lower bound value and the odd-number D is for upper bound value.
2. When X10 = On, the present value in counter C10 will be compared with the four groups of lower and upper
bound values in D100 ~ D107. The comprison results will be stored in M10 ~ M13.
3. When X10 = Off, the original On/Off status of M10 ~ M13 will be remained.

the special data register D1039. Assume the scan time is 30ms and take the above program for example, n =
J100, the time for D10 to increase to D11 will be 3 seconds (30ms × 100).
8. When X10 goes Off, the instruction will stop its execution. When X10 goes On again, the content in D12 will be
reset to 0 for recalculation.
9. When M1026 = Off, M1029 will be On and the content in D12 will be reset to the set value in D10.

K9: Calculate the optimal frequency for positioning instructions with ramp up/ down function.
Users only need to set up the total number of pulses for positioning and the total time for positioning first,
DTM instruction will automatically calculate the optimal max output frequency as well as the optimal start
frequency for positioning instructions with ramp-up/down function such as PLSR, DDRVI and DCLLM.
Points to note:
1. When the calculation results exceed the max frequency of PLC, the output frequency will be set as 0.
2. When the total of ramp-up and ramp-down time exceeds the total time for operation, PLC will change the
total time for operation (S+2) into “ramp-up time (S+3) + ramp-down time (S+4) + 1” automatically.
Explanation on operands:
S+0, S+1: Total number of pulses for operation (32-bit)
S+2: Total time for operation (unit: ms)
S+3: Ramp-up time (unit: ms)
S+4: Ramp-down time(unit: ms)
D+0, D+1: Optimal max output frequency (unit: Hz) (32-bit)
D+2: Optimal start frequency (Unit: Hz)

K11: Conversion from Local Time to Local Sidereal Time
Unlike the common local time defined by time zones, local sidereal time is calculated based on actual
longitude. The conversion helps the user obtain the more accurate time difference of each location within
the same time zone.
Explanation on operands:
S+0, S+1: Longitude (32-bit floating point value; East: positive, West: negative)
S+2: Time zone (16-bit integer; unit: hour)
S+3~ S+8: Year, Month, Day, Hour, Minute, Second of local time (16-bit integer)
D+0~D+5: Year, Month, Day, Hour, Minute, Second of the converted local sidereal time (16-bit integer)
n: Reserved
Example:
Input: Longitude F121.55, Time zone: +8, Local time: AM 8:00:00, Jan/6/2011
Conversion results: AM 8:06:12, Jan/6/2011
K12: Ramp value for multiple points (16-bit)
Explanation on operands (16 bits):
S: input value
S+1, S+2….. S+n: input values for multiple points. The value of these values must be set by the following rule,
S+1 must be the smallest value, S+2 must be larger than S+1 and so on. Therefore, S+n
must be the largest value.
D: ramp value
D+1, D +2 … D+n: Range of ramp values for multiple points
n: Setting value for multiple points. The setting value is within the range between K2 ~ K50. If the setting value
exceeds the range, the instruction is not executed.
The example of a curve is as follows. (n=K4)

3. The floating-point numbers are involved in the operation. The output value is rounded down to the nearest
whole digit, and then the 16-bit integer is output.
K13: Ramp value for multiple points (32-bit)
Please refer to parameter K12 for more information about the operands. The source device and the destination
device are represented by 32-bit values.
K14: Floating-point value for multiple points
Please refer to parameter K12 for more information about the operands. The source device and the destination
device are represented by 32-bit floating-point values.
K16: String combination
Explanations:
The system searches for the location of ETX (value 0x00) of the destination data string (lower 8 bits), then
copies the data string starting of the source register (lower 8 bits) to the end of the destination data string. The
source data string will be copied in byte order until the ETX (value 0x00) is reached.
Points to note:
The operand n sets the max data length after the string combination (max 256). If the ETX is not reached after
the combination, the location indicated by n will be the ETX and filled with 0x00.
The combination will be performed in the following rule:
‘A’

K17: String capture
Explanations:
The system copies the source data string (lower 8 bits) with the data length specified by operand n to the
destination registers, where the n+1 register will be filled with 0x00. If value 0x00 is reached before the specified
capture length n is completed, the capture will also be ended.
The capture will be performed in the following rule:

K18: Convert data string to floating point value
Explanations:
The system converts n words (lower 8 bits) of the source data string (decimal point is not included) to floating
point value and stores the converted value in the destination device.
Points to note:
1. Operand n sets the number of total digits for the converted floating value. Max 8 digits are applicable and
the value over n digit will be omitted. For example, n = K6, data string “123.45678” will be converted to
“123.456”.
2. When there are characters other than numbers 1~9 or the decimal point in the source data string, the
character before the decimal point will be regarded as 0, and the value after the decimal point will be
regarded as the ETX.
3. If the source data string contains no decimal point, the converted value will be displayed by a n-digit
floating point value automatically.
The conversion will be performed in the following rule:

K19: Convert floating point value to data string
Explanations:
The system converts the floating point value in the source device S to data string with specified length n
(decimal point is not included).
Points to note:
7 Application Instructions API 50-99
DVP-PLC APPLICATION MANUAL
7-67
1. Operand n sets the number of total digits for the floating point value to be converted. Max 8 digits are
applicable and the value over n digit will be omitted. For example, n = K6, floating value F123.45678 will be
converted to data string “123.456”.
2. When the digits of source value are more than the specified n digits, only the n digits from the left will be
converted. For example, source value F123456.78 with n=K4 will be converted as data string "1234”.
3. If the source value is a decimal value without integers, e.g. 0.1234, the converted data string will be “.1234”
where the first digit is the decimal point.
The conversion will be performed in the following rule:

Remarks:
1. When this instruction is being executed, it will require 8 scans to obtain one valid keyed-in value. A scan period
that is too long or too short may result in poor keyed-in effect, which can be avoided by the following methods:
a) If the scan period is too short, I/O may not be able to respond in time, resulting in not being able to read the
keyed-in value correctly. In this case, please fix the scan time.
b) If the scan period is too long, the key may respond slowly. In this case, write this instruction into the time
interruption subroutine to fix the time for the execution of this instruction.
2. Functions of M1167:
a) When M1167 = On, HKY instruction will be able to input the hexadecimal value of 0 ~ F.
b) When M1167 = Off, HKY instruction will see A ~ F as function keys.
3. Functions of D1037 (only supports EH/EH2/SV/EH3/SV2 series MPU):
Write D1037 to set the overlapping time for keys (unit: ms). The overlapping time will vary upon different program
scan time and the settings in D1037.

Remarks:
1. When n = K1, D2 will occupy one register. When n = K2, D2 will occupy 2 consecutive registers.
2. Follow the methods below for the transistor scan output:
a) When X10 = On, DSW instruction will be executed. When X10 goes Off, M10 will keep being On until the
scan output completes a scan cycle and go Off.
b) When X10 is used as a button switch, whenever X10 is pressed once, M10 will be reset to Off when the scan
output designated by DSW instruction completes a scan cycle. The DIP switch data will be read completely
and the scan output will only operate during the time when the button switch is pressed. Therefore, even the
scan output is a transistor type, the life span of the transistor can be extended because it does not operate
too frequently.

n: Polarity setting of output signal and scan signal
Explanations:
1. Range of n: 0 ~ 7. See remarks for more details.
2. For ES series MPU, the instruction can only be used once in the program. For EH series MPU, the instruction
can be used twice in the program. For SA series MPU, there is no limitation on the times of using the instruction,
but only one instruction can be executed at a time.
3. For ES/EX/SS/SA/SX/SC series MPU, the last digit of D should be 0 and it does not support E, F index register
modification.
4. Flag: M1029 (SEGL execution completed)
5. This instruction occupies 8 or 12 continuous external input points starting from D for displaying 1 or 2 4-digit
7-segment display data and outputs of scanned signals. Every digit carries a 7-segment display drive (to convert
the BCD codes into 7-segment display signal). The drive also carries latch control signals to retain the
7-segment display.
6. n decides there be 1 group or 2 groups of 4-digit 7-segment display and designates the polarity for the output.
7. When there is 1 group of 4-digit output, 8 output points will be occupied. When there are 2 groups of 4-digit
output, 12 output points will be occupied.
8. When this instruction is being executed, the scan output terminals will circulate the scan in sequence. When the
drive contact of the instruction goes from Off to On again, the scan output terminal will restart the scan again.
Program Example:
1. When X10 = On, this instruction starts to be executed, Y10 ~ Y17 construct a 7-segment display scan circuit.
The value in D10 will be converted into BCD codes and sent to the first group 7-segment display. The value in
D11 will be converted into BCD codes as well and sent to the second group 7-segment display. If the values in
D10 and D11 exceed 9,999, operational error will occur.

4. ES/EX/SS series MPU does not have M1083. During the execution of FROM/TO instruction, all external or
internal interruption subroutines will be forbidden. The interruptions are allowed only after FROM/TO instruction
finishes its execution. FROM/TO instruction can also be used in an interruption subroutine.
5. M1083 for switching instruction modes in SA/SX/SC/EH/EH2/SV/EH3/SV2 series MPU:
a) When M1083 = Off, during the execution of FROM/TO instruction, all external or internal interruption
subroutines will be forbidden. The interruptions are allowed only after FROM/TO instruction finishes its
execution. FROM/TO instruction can also be used in an interruption subroutine.
b) When M1083 = On and an interruption signal occurs during the execution of FROM/TO instruction, the
interruption will be processed first (with a 100us delay) and the execution of FROM/TO will be stopped. After
the interruption subroutine finishes its execution, the program will jump to the next instructio of FROM/TO.
FROM/TO cannot be used in an interruption subroutine.

Operands:
S: Start device for the data to be transmitted m: Length of data to be transmitted D: Start device for receiving
data n: Length of data to be received
Explanations:
1. Range of m: 0 ~ 256
2. Range of n: 0 ~ 256
3. See the specifications of each model for their range of use.
4. ES series MPU does not support E, F index register modification.
5. This instruction is a handy instruction exclusively for MPU to use RS-485 serial communication interface. The
user has to pre-store word data in S data register, set up data length m and the data receiving register D and
received data length n. If E, F index registers are used to modify S and D, the user cannot change the set values
of E and F when the instruction is being executed; otherwise errors may cause in data writing or reading.
6. Designate m as K0 if you do not need to send data. Designate n as K0 if you do not need to receive data.
7. There is no limitation on the times of using this instruction in the program, but only one instruction is allowed to
be executed at a time.
8. During the execution of RS instruction, changing the data to be transmitted will be invalid.
9. If the peripheral devices, e.g. AC motor drive, are equipped with RS-485 serial communication and its
communication format is open, you can use RS instruction to design the program for the data transmission
between PLC and the peripheral device.
10. If the communication format of the peripheral device is Modbus, DVP series PLC offers handy communication
instructions API 100 MODRD, API 101 MODWR, and API 150 MODRW, to work with the device. See
explanations of the instructions in this application manual.
11. For the special auxiliary relays M1120 ~ M1161 and special data registers D1120 ~ D1131 relevant to RS-485
communication, see remarks for more details.
Program Example 1:
1. Write the data to be transmitted in advance into registers starting from D100 and set M1122 (sending request
flag) as On.
2. When X10 = On, RS instruction will be executed and PLC will start to wait for the sending and receiving of data.
D100 starts to continuousl send out 10 data and when the sending is over, M1122 will be automatically reset to

Off (DO NOT use the program to execute RST M1122). After 1ms of waiting, PLC will start to receive the 10 data.
Store the data in consecutive registers starting from D120.
3. When the receiving of data is completed, M1123 will automatically be On. After the program finishes processing
the received data, M1123 has to be reset to Off and the PLC will start to wait for the sending and receiving of
data again. DO NOT use the program to continuously execute RST M1123.

time-out. Please be noted that you have to reset M1129 after the time-out.
D1130 Error code sent back by Modbus
D1168 For RS instruction, when the received number of words = the low byte of D1168, the
interruption I150 will be triggered.
D1169 For RS instruction, when the received data length = the low byte of D1169, the
interruption I160 will be triggered. When D1169 = 0, I160 will not be triggered.
D1256 ~ D1295
When the RS-485 communication instruction MODRW built in PLC is executed, the data
sent will be stored in D1256 ~ D1295. You can check on whether the data sent are
correct by checking these registers.
D1296 ~ D1311 For MODRW instruction, PLC will automatically convert the ASCII characters into hex.

4. When RS instruction is in use, the frequently used communication format in the peripheral device will define the
start word and end word of the control string. Therefore, you can set up the start word and end word in D1124 ~
D1126 or use the start word and end word defined by the PLC. When you use M1126, M1130 and D1124 ~
D1126 to set up the start word and end word, b8 ~ b10 of D1120 have to be set as 1 to make valid the RS-485
communication protocol. See the table below for how to set up.

When STX, ETX1 and EXT2 are in use, please be aware of the On and Off of the special auxiliary relays M1126
and M1130.
6. M1143 is for the selection of ASCII mode or RTU mode. On = RTU mode; Off = ASCII mode.
Take the standard Modbus format for example:
In ASCII mode (M1143 = Off)
STX Start word = ‘:’ (3AH)
Address Hi
Address Lo
Communication address:
The 8-bit address consists of 2 ASCII codes
Function Hi
Function Lo
Function code:

LRC CHK Hi
LRC CHK Lo
LRC checksum:
The 8-bit checksum consists of 2 ASCll code
END Hi
END Lo
End word:
END Hi = CR (0DH), END Lo = LF(0AH)
The communication protocol is in Modbus ASCII mode, i.e. every byte is composed of 2 ASCII characters. For
example, 64Hex is ‘64’ in ASCII, composed by ‘6’ (36Hex) and ‘4’ (34Hex). Every hex ‘0’…’9’, ‘A’…’F’
corresponds to an ASCII code.
Character ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’
ASCII code 30H 31H 32H 33H 34H 35H 36H 37H
Character ‘8’ ‘9’ ‘A’ ‘B’ ‘C’ ‘D’ ‘E’ ‘F’
ASCII code 38H 39H 41H 42H 43H 44H 45H 46H
Start word (STX):
Fixed as ‘:’ (3AH)
Address:
‘0’ ‘0’: Broadcasting to all drivers
‘0’ ‘1’: To the driver at address 01
‘0’ ‘F’: To the driver at address 15
‘1’ ‘0’: To the driver at address 16
….and so on, maximum to the driver at address 255 (‘F’ ‘F’)
Function code:
‘0’ ‘3’: Read contents of many registers
‘0’ ‘6’: Write 1 word to register
‘1’ ‘0’: Write in contents of many registers
Data characters: The data sent by the user.
LRC checksum:
LCR checksum is 2’s complement of the value added from Address to Data Content.
For example: 01H + 03H + 21H + 02H + 00H + 02H = 29H. 2’s complement of 29H = D7H
End word (END):

CRC checksum: Starting from Address and ending at Data Content.
Step 1: Make the 16-bit register (CRC register) = FFFFH
Step 2: Exclusive OR the first 8-bit message and the low 16-bit CRC register. Store the result in the CRC
register.
Step 3: Right shift CRC register for a bit and fill “0” into the high bit.
Step 4: Check the value shifted to the right. If it is 0, fill in the new value obtained in step 3 and store the value
in CRC register; otherwise, Exclusive OR A001H and CRC register and store the result in the CRC
register.
Step 5: Repeat step 3 – 4 and finish operations of all the 8 bits.
Step 6: Repeat step 2 – 5 for obtaining the next 8-bit message until the operation of all the messages are
completed. The final value obtained in the CRC register is the CRC checksum. The CRC checksum
has to be placed interchangeably in the checksum of the message.

2. See the specifications of each model for their range of use.
3. Flags: M1178, M1179. See remarks for more details.
4. VRRD instruction is used for reading 2 points (No.0, No.1) of PLC or the VR rotary switch volume change in the 6
points of the function cards (No.2 ~ No.7) and converting the data into values 0 ~ 255 (stored in D).
5. If you are to set up the timer by the VR volume, simply rotate the VR to modify the set time in the timer. If you are
to acquire a value larger than 255, multiply D by a constant.
Program Example 1:
1. When X0 = On, VR0 volume changed will be converted into an 8-bit BIN value (0 ~ 255) and stored in D0.
2. When X1 = On, the imer T0 will start to time with the content in D0 as the set value in the timer.

instruction. E index register modification is used in the example below, K0E = K0 ~ K7.
2. The timer converts the scale 0 ~ 10 on the rotary switch into 0 ~ 255. The timing unit of T0 ~ T7 is 0.1 second;
therefore, the set time in the timer will be 0 ~ 25.5 seconds.

Explanations:
1. In 16-bit instruction, S3 will occupy 20 consecutive devices; in 32-bit instruction, S3 will occupy 21 consecutive
devices.
2. See the specifications of each model for their range of use.
3. See the Remarks below for the times of using PID instruction allowed in the program.
4. This instruction is specifically for PID control. PID operation will be executed by the scan only when the sampling
time is reached. PID refers to “proportion, integration and differential”. PID control is widely applied to many
machines, pneumatic and electronic equipments.
5. For the 16-bit instruction, the parameters are S3 ~ S3+19; for the 32-bit instruction, the parameters are S3 ~ S3+20.
After all the parameters are set up, PID instruction will start to be executed and the results will be stored in D. D
has to be the data register area without latched function. (If you wish to designate a latched data register area,
place the data register in the latched area at the beginning of the program and clear it as 0.)
Program Example:
1. Complete the parameter setting before executing PID instruction.
2. When X0 = On, the instruction will be executed and the result will be stored in D150. When X0 goes Off, the
instruction will not be executed and the data prior to the instruction will stay intact.

Remarks:
1. ES/EX/SS series MPU V5.7 (and above) supports PID instruction. Other versions do not support the instruction.
2. There is no limitation on the times of using this instruction. However, the register No. designated in S3 cannot be
repeated.
3. For the 16-bit instruction, S3 will occupy 20 registers. In the program example above, the area designated in S3 is
D100 ~ D119. Before the execution of PID instruction, you have to transmit the setting value to the designated
register area by MOV instruction, If the designated registers are latched, use MOVP instruction to transmit all
setting value at a time.

designated in S3 +4. Other relevant settings of PID operation are set by the registers designated in S3 ~ S3 +5.
3. Basic PID equation:

tE is less than 0
as the control direction is selected as forward or inverse,

The equation above illustrates that this instruction is different from a general PID instruction by the variable use
of the differential value. To avoid the flaw that the transient differential value is too big when a general PID
instruction is executed for the first time, our PID instruction monitors the differentiation status of the PV. When
the variation of PV is too big, this instruction will reduce the output of MV.

In which the error value is fixed as E(t) = SV – PV
This equation is exclusively designed for temperature control. Therefore, when the sampling time (TS) is set as 4
seconds (K400), the range of output value (MV) will be K0 ~ K4,000 and the cycle time of GPWM instruction
used together has to be set as 4 seconds (K4000) as well.
If you have no idea how to adjust the parameters, you can select K3 (auto-tuning) and after all the parameters
are adjusted (the control direction will be automatically set as K4), you can modify your parameters to better
ones according to the result of the control.

7. Notes:
7 Application Instructions API 50-99
DVP-PLC APPLICATION MANUAL
7-126
a) S3 + 6 ~ S3 + 13 are only available in SA/SX/SC/EH/EH2/SV series, and ES/EX/SS (v5.7 and above) series
MPU.
b) PID instruction can only be used once in ES/EX/SS (v5.6 and below) series MPU. There is no limitation on
the times of using PID instruction in ES/EX/SS (v5.7 and above) series and SA/SX/SC/EH/EH2/SV/EH3/SV2
series MPU.
c) S3 + 3 of ES/EX/SS (v5.7 and below), SA/SX/SC (v1.1 and below) and EH (v1.0 and below) series MPU can
only be the value within 0 ~ 30,000.
d) There are a lot of circumstances where PID instruction can be applied; therefore, please choose the control
functions appropriately. For example, when you select parameter auto-tuning for the temperature (S3 + 4 =
K3), you cannot use it in a motor control environment in case improper control may occur.
e) When you adjust the three main parameters, KP, KI and KD (S3 + 4 = K0 ~ K2), you have to adjust KP first
(according to your experiences) and set KI and KD as 0. When you can roughly handle the control, you then
adjust KI (increasingly) and KD (increasingly) (see example 4 below for how to adjust). KP = 100 refers to
100%, i.e. the gain of the error is 1. KP < 100% will decrease the error and KP > 100% will increase the error.
f) When you select the parameter exclusively for temperature control (S3 + 4 = K3, K4), it is suggested that you
store the parameter in D register in the latched area in case the automatically adjusted parameter will
disappear after the power is cut off. There is no guarantee that the adjusted parameter is suitable for every
control. Therefore, you can modify the adjusted parameter according to your actual need, but it is suggested
that you modify only KI or KD.
g) PID instruction can to work with many parameters; therefore please do not randomly modify the parameters
in case the control cannot be executed normally.

= (most models of motors are first-order function), SV = 1, and sampling time (TS) = 10ms, we
suggest you to follow the steps below for adjusting the parameters.
Step 1: Set KI and KD as 0 and KP as 5, 10, 20 and 40. Record the SV and PV respectively and the results
are as the figure below.

Step 2: From the figure, we can see that when KP = 40, there will be over-reaction, so we will not select it.
When KP = 20, the PV reaction curve will be close to SV and there will not be over-reaction, but due to its
fast start-up with big transient MV, we will consider to put it aside. When KP = 10, the PV reaction curve will
get close to SV value more smoothly, so we will use it. Finally when KP = 5, we will not consider it due to the
slow reaction.
Step 3: Select KP = 10 and adjust KI from small to big (e.g. 1, 2, 4 to 8). KI should not be bigger than KP.
Adjust KD from small to big (e.g. 0.01, 0.05, 0.1 and 0.2). KD should not exceed 10% of KP. Finally we
obtain the figure of PV and SV below.

Application 1 Using PID instruction in the pressure control system (use the diagram of Example 1).
Purpose: Enabling the control system to reach the target pressure.
Explanation: The system requires a gradual control. Therefore, the system will be overloaded or out of control if the
process progresses too fast.

Application 2 Speed control system and pressure control system work individually (use diagram of Example 2).
Purpose: After the speed control operates in open loop for a period of time, adding into it the pressure control system
(PID instruction) for close loop control.
Explanation: Since the speed and pressure control systems are not interrelated, we have to structure a open loop for
speed control first following by a close loop pressure control. If you fear that the control instruction of the
pressure control system changes too fast, you can consider to add the instruction delay illustrated in
Application 1 into the control. See the control diagram below.

Application 3 Using auto-tuning on the parameter for the temperature control.
Purpose: Using auto-tuning to calculate the most suitable parameters for PID temperature control.
Explanation: You may not be familiar with the temperature environment for the first time, so you can use auto-tuning
(S3 + 4 = K3) for an initial adjustment. After this, PID instruction will become exclusively for temperature
control (S3 + 4 = K4). In this example, the control environment is an oven. See the example program

approximately 20 minutes for the control. Next, we modify the target temperature from 80°C to 100°C and obtain the
result below.
From the result above, we can see that when the parameter is 100°C, we can still control the temperature without
spending too much time.

7. If the address of S2 is illegal to the designed communication device, the device will respond with an error, PLC
will records the error code in D1130 and M1141 will be On.
8. The feedback (returned) data from the peripheral equipment will be stored in D1070 ~ D1085. After receiving
the feedback data is completed, PLC will auto-check if all data are correct. If there is an error, M1140 will be On.
9. In ASCII mode, due to that the feedback data are all in ASCII, PLC will convert the feedback data into numerals
and store them in D1050 ~ D1055. D1050 ~ D1055 will be invalid in RTU mode.
10. After M1140 or M1141 turn On, the program will send a correct datum to the peripheral equipment. If the
feedback datum is correct, M1140 and M1141 will be reset.

Explanations:
1. Range of n: K1 ~ K256
2. See the specifications of each model for their range of use.
3. Flag: M1161 (switching between 8/16 bit modes)
4. n has to be even. If n does not fall within its range, an operation error will occur, the instruction will not be
executed, M1067, M1068 = On and D1067 will record the error code H’0E1A.
5. In 16-bit conversion mode: When M1161 = Off, S divides its hex data area into higher 8 bits and lower 8 bits
and performs LRC checksum operation on each bit. The data will be sent to the higher 8 bits and lower 8 bits in
D. n = the number of calculated bits.
6. In 8-bit conversion mode: When M1161 = On, S divides its hex data area into higher 8 bits (invalid data) and
lower 8 bits and performs LRC checksum operation on each bit. The data will be sent to the lower 8 bits in D
and occupy 2 registers. n = the number of calculated bits. (All higher bits in D are “0”.)
Program Example:

Operands:
S: Start operation device for RTU mode checksum n: Number of calculated bits D: Start device for storing the
operation result CRC checksum: See remarks.
Explanations:
1. Range of n: K1 ~ K256
2. Flags: M1161 (switching between 8/16-bit modes)
3. If n does not fall within its range, an operation error will occur, the instruction will not be executed, M1067,
M1068 = On and D1067 will record the error code H’0E1A.
4. In 16-bit conversion mode: When M1161 = Off, S divides its hex data area into higher 8 bits and lower 8 bits
and performs CRC checksum operation on each bit. The data will be sent to the higher 8 bits and lower 8 bits in
D. n = the number of calculated bits.
5. In 8-bit conversion mode: When M1161 = On, S divides its hex data area into higher 8 bits (invalid data) and
lower 8 bits and performs CRC checksum operation on each bit. The data will be sent to the lower 8 bits in D
and occupy 2 registers. n = the number of calculated bits. (All higher 8 bits in D are “0”.)
Program Example:
When PLC communicates with VFD-S series AC motor drives (In RTU mode, M1143 = On), (In 16-bit mode, M1161 =
On), the sent data write in advance H12 into H2000 of VFD-S.

2. CRC checksum starts from Address and ends at Data content.
The operation of CRC checksum:
Step 1: Make the 16-bit register (CRC register) = FFFFH
Step 2: Exclusive OR the first 8-bit byte message instruction and the low-bit 16-bit CRC register. Store the
result in CRC register.
Step 3: Shift the CRC register one bit to the right and fill 0 in the higher bit.
Step 4: Check the value that shifts to the right. If it is 0, store the new value from Step 3 into the CRC register,
otherwise, Exclusive OR A001H and the CRC register, and store the result in the CRC register.
Step 5: Repeat Step 3 ~ 4 and finish calculating the 8 bits.
Step 6: Repeat Steps 2 ~ 5 for obtaining the next 8-bit message instruction until all the message instructions
are calculated. In the end, the obtained CRC register value is the CRC checksum. Be aware that
CRC checksum should be placed in the checksum of the message instruction.

6. Pulse output devices D: Y, M, S.
7. When being executed, GPWM instruction designates S1 and S2 and that pulses output will be from device D.
8. When S1 ≤ 0, there will be no pulse output. When S1 ≥ S2, the pulse output device will keep being On.
9. S1 and S2 can be modified when GPWM instruction is being executed.
Program Example:
When X0 = On, D0 = K1,000, D2 = K2,000, and Y10 will output the pulse illustrated below. When X0 = Off, Y10 output
will be Off.

Explanations:
1. This instruction counts by the scan cycle; therefore the maximum offset will be one PLC scan cycle. S1, S2 and
(S2 - S1) should > PLC scan cycle; otherwise, errors will occur during GPWM outputs.
2. Please note that placing this instruction in a subroutine or interruption will cause inaccurate GPWM outputs.

Operands:
S1: Set value (SV) S2: Present value (PV) S3: Parameter (sampling time) D: Output value (MV)
Explanations:
1. Range of S1 : 1 ~ 5000 (shown as 0.1°C ~ 500°C). Unit: 0.1°. If (S3 +1) is set as K0, the range will be 0.1°C ~
500°C.
2. Range of S2 : 1 ~ 5000 (shown as 0.1°C ~ 500°C). Unit: 0.1°. If (S3 +1) is set as bit0 = 0, the range will be 0.1°C
~ 500°C. Therefore, when the user obtain an A/D value from the temperature sensor, the value has to be
converted into a value between 1 ~ 5,000 by four arithmetic operation instructions.
3. If S3 < K1, the instruction will not be executed. If S3 > K200, S3 will adopt K200. S3 will occupy 7 consecutive
devices.
4. See the specifications of each model for their range of use.
5. Settings of parameter S3 +1: bit0 = 0 ->°C; bit1 = 0 ->°F; bit1 = 0 -> no filter function; bit1 = 1 -> with filter
function; bit2 ~ bit5 -> 4 kinds of heating environments; bit6 ~ bit15 -> reserved. See remarks for more
information.
6. D is the value between 0 ~ sampling time × 100. When using this instruction, the user has to adopt other
instructions according to the types of the heater. For example, FTC can be used with GPWM for output pulse
control. “Sampling time × 100” is the cycle of GPWM pulse output; MV is the width of GPWM pulse. See
program example 1.
7. There is no limit on the times of using FTC instruction, but Do not repeatedly use a designated operand in case
an error may occur..
Program Example:
1. Set up the parameter before executing FTC instruction.
2. When X0 = On, the instruction will be executed and and result will be stored in D150. When X0 = Off, the
instruction will not be executed and the previous data remain unchanged.

3. Notes and suggestion:
It is recommended that the sampling time be set to 2 times more than the sampling time of the temperature
sensor for better temperature control.
bit2 ~ bit5 of S3+1 are for the control speed. If the user does not set up the parameter, FTC will automatically
activate “general heating environment”. When the user finds that the control is too slow to reach SV, select “slow

too fast or with too many fluctuations, select “fast heating environment” to slow down the control speed.
When bit2 ~ bit5 of S3+1 are all set as 1 or more than 1 environments are designated, FTC instruction will check
from bit2 to bit 5 in order and enable the function that has been set as 1. The parameter can be modified during

Experiment in an oven which can be heated up to 250°C. See below for the records of target and present
temperatures. As shown in the diagram below, we can see that after 48 minutes, the temperature is able to
reach the target temperature with ±1oC inaccuracy and exceed approx. 10°C of the target temperature.
Example 2: Due to that the temperature once exceeds the target temperature, we modify the heating
environment into “fast heating environment” (D13 = K16). The results are shown in the diagram below.
From the diagram below, we see that though the temperature no longer exceeds the target temperature, it still
needs to take more than 1 hour and 15 minutes to reach the target temperature with ±1oC inaccuracy. It seems
that we have chosen the right environment, but the sampling time is too long, resulting in the extension of
heating time.

Example 3: To speed up the speed to reach the target temperature, we correct the sampling time as 4 seconds
(D12 = K40, D30 = K4,000). The results are shown in the diagram below.
From the diagram below, we see that the overall control time has been shortened as 37 minutes. Therefore, we
find out that modifying the sampling time can speed up the time for reaching the target temperature.
Example 4: To see if we can reach the target temperature faster, we modify the sampling time frim example 3
into 2 seconds (D12 = K20, D30 = K2,000). The results are shown in the diagram below.
From the diagram below, we see that the sampling time that is too short will cause the control system to become
too sensitive and lead to up and down fluctuations.

Operands:
S1: Target time of valve (absolute position) S2: Time from fully-closed to fully-open of valve (destination)

Explanations:
1. S1 occupies 3 consecutive registers when in use. S1 + 0 are for the user to store the designated value; S1 + 1 (the
current position of the valve) and S1 + 2 are for storing the parameters recorded in the instruction and please DO
NOT use and alter these two registers.
2. D occupies 2 consecutive output devices when in use. D + 0 is the “open” contact and D + 1 is the “close” contact.
3. This instruction only supports EH2/SV/EH3/SV2 and does not support EH.
4. The unit of time: 0.1 second. When the scan time of the program exceeds 0.1 second, DO NOT use this
instruction to adjust the position of the valve.
5. Frequency of the output device: 10Hz.
6. When the time of S1 + 0 ＞ the fully-opened time set in S2, D + 0 will keep being On and D + 1 being Off. When
the time of S1 + 0 ＜ 0, D + 0 will keep being Off and D + 1 being On.
7. When the instruction is enabled, the instruction will start to control the valve from “0” time position. Therefore, if
the user cannot be sure whether the valve is at “0” before executing the instruction, please designate S1 + 0 as
less than 0 and execute the instruction for S2 (time) before sending in the correct target control time.

file register to the designated data register by M1101 (whether to enable the function of file register), D1101
(start address in file register K0 ~ K9,999), D1102 (number of data to be read in file register K1 ~ k8,000), and
D1103 (device for storing read data, starting from designated D, K2,000 ~ K9,999).
8 Application Instructions API 100-149
DVP-PLC Application Manual 8-67
2. In EH/EH2/SV/EH3/SV2, the reading of data from file register to data register D will not be executed if D1101 <
0, D1101 > K9,999, D1103 < K2,000 or D1103 > K9,999.
3. SA/SX/SC: When the PLC is powered, it will decide whether to automatically send the data in the file register to
the designated data register by M1101 (whether to enable the function of file register), D1101 (start address in
file register K0 ~ K1,599), D1102 (number of data to be read in file register K1 ~ k1,600), and D1103 (device for
storing read data, starting from designated D, K2,000 ~ K4,999).
4. In SA/SX/SC, the reading of data from file register to data register D will not be executed if D1101 < 0, D1101 >
K1,599, D1103 < K2,000 or D1103 > K4,999.
5. When the reading of data from file register to data register D starts, PLC will stop the reading if the address of
file register or data register exceed their range.
6. In PLC program, only API 148 MEMR and API 149 MEMW can be used to read or write the file register. See
2.8.3 for more information on file registers.
7. File registers do not have actual addresses in it. Reading and writing of file registers can only be done through

Explanations:
1. The content of S2 shall only be: K3(H03), K6(H06), K16(H10). SA/SX V1.8, SC V1.6 and EH2/SV/EH3/SV2
V1.2 and later versions support K2(H02) and K15(H0F); EH2/SV/EH3/SV2 V1.4 and later versions support
K5(H05).
2. ES/EX/SS V.4.9 (and above) support the continuous execution instruction (MODRW). Other versions do not
support this instruction.
3. ES/EX/SS series MPU does not support E, F index register modification.
4. Flags: M1120 ~ M1131, M1140 ~ M1143. See remarks for more details.
5. Range of S1: K0 ~ K254

7. S3: Device address of data to be read/written. The device address inside the communication device. If the
address is illegal to a designated communication device, the communication device will respond with an error
message and PLC will store the error code in D1130 and M1141 = On. For example, if 8000H is illegal to
VFD-S, M1141 will be On and D1130 = 2. See user manual of VFD-S for error codes.
8. S: Register for storing read/written data. The user sets up a register and stores the data to be written in the
register in advance. The register can be register for storing the read data.
9. n: Length of read/written data.

10. There is no limitation on the times of using this instruction. However, only one instruction can be executed at a
time.
Program Example 1:
1. Function code K3(H03): For reading many data in register
When PLC is connected to VFD-S AC motor drive: M1143 = Off, in ASCII mode
When PLC is connected to VFD-S AC motor drive: M1143 = On, in RTU mode
2. When in ASCII mode, the received data will be stored in the designated registers starting from D0 in ASCII
format and PLC will automatically convert the data into hex value and store them in special registers D1296 ~
D1311. When the conversion into hex value starts, M1131 will be On and turn Off when the conversion is
completed.
3. If necessary, the user can move the hex values stored in D1296 ~ D1131 to other general registers by using
MOV, DMOV or BMOV instruction. Other instructions of ES/EX/SS do not function on the data in D1296 ~
D1311.
4. When in RTU mode, the received data will be stored in the designated registers starting from D0 in hex format.
5. When In ASCII mode or RTU mode, PLC will store the data to be sent in D1256 ~ D1295. If necessary, the
user can move the data to other general registers by using MOV, DMOV or BMOV instruction. Other
instructions of ES/EX/SS do not function on the data in D1256 ~ D1295.
6. The data sent back from AC motor drive are stored in the registers designated by the user. After the
transmission is completed, PLC will auto-check if the received data are incorrect. M1140 will be On if there is
an error.
7. If the device address is illegal to a designated communication device, the communication device will respond
with an error message and PLC will store the error code in D1130 and M1141 = On. For example, if 8000H is
illegal to VFD-S, M1141 will be On and D1130 = 2. See user manual of VFD-S for error codes.
8. After M1140 = On or M1141 = On, PLC will send another correct datum to AC motor drive. If the data sent back
from AC motor drive is correct, M1140 and M1141 will be reset.

Operands:
S: Source device D: Destination device for storing the detected result
Explanations:
1. Range of S: X10 ~ X17
2. Range of D: D0 ~ D999, occupying 2 consecutive devices. Can only be used once in the program.
3. PWD instruction is for detecting the time span of output signals from X10 ~ X17; the valid frequency range is 1
~1kHz. When M1169 = On, the instruction will detect the time span of the continuous rising edge and falling
edge of the input signals (time unit: 100us). When M1169 = On, the instruction will detect the time span of 2
continuous rising edges of the input signals (time unit: 1us). It cannot designate the same X10 ~ X17 as does
DCNT and ZRN instructions.
4. D occupies two continuous devices. The longest detectable time is 21,474.83647 seconds, about 357.9139
minutes or 5.9652 hours.
5. There is no limitation on the times of using this instruction. However, only one instruction can be executed at a
time.
Program Example:
When X0 = On, record the time span of X10 = On and store it in D1 and D0.

Explanations:
1. Range of D: K0 ~ K9
2. Range of n: K10 ~ K500
3. The designated special D registers (D1156 ~ D1165) can measure up to 10 interruption subroutines. For
example, when D = K5, the designated D register will be D1161.
4. When RTMU is executed, if the D and n entered by the user are legal, interruption of the timer will be enabled
and the counting starts and the special D designated by D is cleared as 0. When RTMD is executed,
interruption of the timer is disabled and the calculated time will be assigned to special D designated by RTMD.
5. With API 153 RTMD, RTMU can measure the execution time of “I” interruption service subroutine, which can
be reference for dealing with the high-speed response when the user is at the initial stage of developing the
program.

result of the measurement may be unexpectable.
Program Example:
When X0 goes from Off to On, the program will enter I001 interruption subroutine. RTMU will activate an 8-bit timer
(unit: 10us) and RTMD (when D = K0) will shut down the timer and store the time in the timer in special D registers

Remarks:
1. We suggest you remove this instruction after you finish developing your PLC program.
2. Due to the lower priority of the interruption enabled by RTMU, when RTMU is enabled, other high-speed pulse
input counting or high-speed pulse output may result in failure to trigger the timer.
3. If you activate RTMU but do not activate RTMD before the end of the interruption, the interruption will not be
shut down.

you designate the two corresponding registers. If you designate other devices as the registers, you still have to
transmit the data to D1337 and D1336 of CH0 or D1339 and D1338 of CH1. In addition, the absolute position
data should be written into the present value registers (D1348, D1349) of CH0 pulse (Y10) or the present value
registers (D1350, D1351) of CH1 pulse (Y11) in SC series MPU; therefore, we suggest you designate the two
corresponding registers. If you designate other devices as the registers, you still have to transmit the data to
D1348 and D1349 of CH0 or D1350 and D1351 of CH1.
9. When DABSR instruction starts to read, after finishing reading the absolute position of SERVO, flag M1029 will
be On. The user has to reset the flag.
10. When driving the DABSR command, please specify normally open contact. If the drive contact of DABSR
command turns Off when DABSR command read starts, the execution of absolute current value read will be
interrupted and result in incorrect data. Please be careful and notice that.
Program Example:
1. When X7 = On, the 32-bit absolute position data read from Servo will be stored in the present value registers
(D1337, D1336) of CH0 pulse in EH MPU. At the same time, the timer T10 is enabled and starts to count for 5
seconds. If the reading of the absolute position is not completed after 5 seconds, M10 will be On, indicating that
the reading of absolute position encounters abnormality.
2. When enabling the connection to the system, please synchronize the power input of DVP-PLC
EH/EH2/SV/EH3/SV2 and SERVO AMP or activate the power of SERVO AMP earlier than DVP-PLC.

Operands:
S1: Zero return speed S2: Creep speed S3: Near p oint signal (DOG) D: Pulse output device (please use
transistor output module)
Explanations:
1. When S1 and S2 are used in device F, only 16-bit instruction is applicable.
2. S1 and S2 of SC series MPU only support device K, H and D. S3 of SC series MPU only supports device X10
and X11.
3. Flag: see remarks of API 155 ABSR and API 158 DDRVI for more details.
4. S1 is the starting speed of zero return operation. For EH2/SV/EH3/SV2 series MPU, the 16-bit instruction can
designate the range of the speed, which is 10 ~ 32,767Hz and the range designated by the 32-bit instruction is
10 ~ 200,000Hz. If the designated speed is slower than 10Hz, the zero return will operate at 10Hz and when
the designated speed is faster than 200kHz, the zero return will operate at 200kHz. For SC series MPU, the
32-bit instruction can designate the range of speed , which is 100 ~ 100,000Hz. If the designated speed is
slower than 100Hz, the zero return will operate at 100Hz, and when the designated speed is faster than
100kHz, the zero return will operate at 100kHz.
5. S2 is the designated low speed after the near point signal (DOG) is On. EH2/SV/EH3/SV2 series MPU can
designate the range of S2, which is 10 ~ 32,767Hz and SC series MPU can designate the range 100 ~
100,000Hz.
6. S3 is the designated near point signal (DOG) input (input from A contact). In EH2/SV/EH3/SV2 series MPU, if
devices other than the external output device (X10 ~ X17), e.g. X, Y, M, S are designated, they will be affected
by the scan period, resulting in dispersion of the zero point. In addition, please note that the MPU cannot
designate the same input points X10 ~ X17 as those designated by DCNT and PWD instructions. SC series
MPU can only designate X10 and X11 and cannot designate the same input points as those designated by
DCNT instruction.
7. EH series MPU has two groups of A/B phase pulse output, CH0 (Y0, Y1) and CH1 (Y2, Y3); EH2/SV/EH3/SV2
series MPU has four groups of A/B phase pulse output, CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4, Y5) and CH3
(Y6, Y7). See remarks for the setup methods.

9. EH3/SV2: The instruction DZRN can be used to detect the limit switch, nake the pulsed output stop at the
positive position, search for the Z phase, and output a certain number of displacement. Therefore, when the

10. When executing API 158 DRVI (releative positioning) or API 159 DRVA (absolute positioning), PLC will
automatically store the increasing or decreasing forward/reverse pulses in the present value registers. For
EH2/SV/EH3/SV2 series MPU, Y0: D1337, D1336; Y2: D1339, D1338, Y4: D1376, D1375; Y6: D1378, D1377.
For SC series MPU, Y10: D1348, D1349; Y11: D1350, D1351. In this way, you can keep track of the position of
the machine at any time. However, due to that the data will be lost when the power of the PLC is switched off,
you have to enter the zero point position of the machine when executing zero return for the first time.
Program Example:
When M10= On, Y0 output pulses start to operate zero return at the frequency of 20kHz. When the zero return meets
DOG X15 = On, Y0 output pulses will start to operate by creep speed 1kHz until X15 is Off.

a) When ZRN instruction is executed, the frequency of the first acceleration segment of CH0 (CH1) in
EH2/SV/EH3/SV2 series MPU is set by D1340 (D1352). In SC series MPU, CH0 (CH1) will set creep speed
as the start frequency. The acceleration time of EH2/SV/EH3/SV2/SC series MPU is set by D1343 (D1353).
S1 will start to move when the acceleration reaches the zero return speed.
b) When the DOG signal goes from Off to On, the zero return speed will decelerate to S2 by the time set in
D1343 (D1353).
c) When the DOG signal goes from On to Off and the pulse output stops, 0 will be written in the present value
registers (D1337, D1336) of CH0 pulses, D1339 and D1338 of CH1 pulses, D1375 and D1376 of CH2 pulses,
and D1377 and D1378 of CH3 pulses in EH2/SV/EH3/SV2 series MPU; 0 will also be written in D1348 and
D1349 of Y10 (CH0) pulses or D1350 and D1351 of Y11 (CH1) pulses in SC series MPU.
d) When the DOG signal goes from On to Off and the reset signal flag M1346 = On, Y4 (CH0) or Y5 (CH1) in EH
series MPU will output a reset signal; Y10 (CH0), Y11 (CH1) , Y12 (CH2) and Y13 (CH3) in EH2/SV/EH3/SV2
series MPU will output a reset signal.
e) For EH2/SV/EH3/SV2 series MPU, when the pulse output is completed and M1029, M1030, M1036 and
M1037 are enabled, indication flag M1336 sent by CH0 pulses, M1337 by CH1, M1522 by CH2 and M1523
by CH3 will be Off. For SC series MPU, when the pulse output is completed, M1102 and M1103 will be
enabled.

f) Due to that ZRN (DZRN) instruction cannot locate the position of DOG, the zero return can only be done
towards a single direction. In the zero return operation of EH2/SV/EH3/SV2 series MPU, D1337 and D1336
(present value registers) of CH0 pulses or D1339 and D1338 of CH1 pulses are decreasing. In the zero return
operation of SC series MPU, D1348 and D1349 of CH0 pulses or D1350 and D1351 of CH1 pulses are also
decreasing.

g) ZRN (DZRN) instruction is applicable to servo motor with absolute positioning function, e.g. Mitsubishi
MR-J2-A servo drive. Even when the power is switched off, the current position can still be recorded. In
addition, the current position of servo drive can be read by API 155 DABSR of EH2/SV/EH3/SV2/SC series
MPU; therefore only one zero return operation is required and no zero return has to be done after the power is
switched off.
h) When the drive contact of ZRN instruction is On, CH0 (CH1) will read the acceleration/deceleration time set in
D1343 (D1353) and accelerate to the zero return speed, waiting for the DOG and decelerate to creep speed.
When the DOG is Off, the pulse output will stop immediately.
i) For SC series MPU, many ZRN instructions can be compiled in the program but only one instruction can be
executed when the PLC program is being executed. For example, provided there is already an instruction
enabling Y10 output, other instructions enabling also Y10 output will not be executed. The principle of the
instruction execution is “first come, first executed”.
j) For SC series MPU, when you designate Y10 as the output device, you can choose either X10 or X11 for
DOG input in the “acceleration to deceleration” segment. In other words, when designating Y11 as the output
device, you can also choose either X10 or X11 for DOG input.
k) For SC series MPU, due to that this instruction does not compare between the number of output pulses, the
DOG input (from Off to On) will therefore become the trigger of acceleration converting to deceleration. The
“On” time of DOG has to be longer than 10us; otherwise the signal may be regarded as useless interference.
l) For SC series MPU, when the execution of the instrucion enters the deceleration segment and the output
frequency reaches creep speed (end frequency), the output will stop when DOG goes from On to Off.
m) For SC series MPU, the current accumulated number of pulses of Y10 is stored in D1348 and D1349 and that
of Y11 is stored in D1350 and D1351. Then the program operates from STOP to RUN or from RUN to STOP,

the contents will not be cleared to 0.
n) For SC series MPU, M1102 = On indicates the end of Y10 pulse output; M1103 = On indicates the end of Y11
pulse output.
o) For SC series MPU, after the instruction is executed, all parameters cannot be modified unless the execution
of the instruction stops.
p) For SC series MPU, when the execution of the stops, all outputs will stop immediately no matter what type of
the output it is.

Explanations:
1. See remarks for the setting range of S, D1 and D2.
2. Flag: see remarks of API 155 ABSR and API 158 DDRVI for more details.
3. S is the designated pulse output frequency. The 16-bit instruction can designate its range 0 ~ +32,767Hz, 0 ~
-32,768Hz. The ranges designated by 32-bit instruction are 0 ~ +200,000Hz and 0 ~ -200,000Hz. “+/-” signs

designate Y0, Y2, Y4 and Y6.
5. The operation of D2 corresponds to the “+” or “-“ of S. When S is “+”, D2 will be On; when S is “-“, D2 will be Off.
6. PLSV instruction does not have settings for acceleration and deceleration. Please use API 67 RAMP for the
acceleration and deceleration of pulse output frequency.
7. During the pulse output executed by PLSV instruction, the drive contact turning Off will result in the immediate
stop of the output without going through a deceleration.
8. When the absolute value of the input frequency during the execution of DPLSV is bigger than 200kHz, the
output will operate at 200kHz.
9. For EH/EH2/SV/EH3/SV2 series MPU, D1222, D1223, D1383 and D1384 are the time differences sent
between the direction setup signal and pulse output points of CH0, CH1, CH2 and CH3.
10. For EH/EH2/SV/EH3/SV2 series MPU, M1305, M1306, M1532 and M1533 are the flags of the direction signals
of CH0, CH1, CH2 and CH3. When S is “+”, the output will operate towards a forward direction and the flag will
go Off. When S is “-“, the output will operate towards a backward direction and the flag will go On.

2. S1 and S2 of SC series MPU only support device K, H and D.
3. Flag: see remarks for more details.
4. S1 is the number of output pulses (relative designation). For EH/EH2/SV/EH3/SV2 series MPU, the 16-bit
instruction can designate the range -32,768 ~ +32,767. The range designated by 32-bit instruction is
-2,147,483,648 ~ +2,147,483,647. For SC series MPU, the 32-bit instruction can designate the range
-2,147,483,648 ~ +2,147,483,647. “+/-” signs indicate forward/backward directions.
5. S2 is the designated pulse output frequency. For EH/EH2/SV/EH3/SV2 series MPU, the 16-bit instruction can
designate its range 10 ~ 32,767Hz. The range designated by 32-bit instruction is 10 ~ 200,000Hz. For SC
series MPU, the 32-bit instruction can designate the range 100 ~ 100,000Hz.
6. EH series MPU has two groups of A/B phase pulse output, CH0 (Y0, Y1) and CH1 (Y2, Y3). EH2/SV/EH3/SV2
series MPU has four groups of A/B phase pulse output, CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4, Y5) and CH3
(Y6, Y7). See remarks for the setup methods.

8. The operation of D2 corresponds to the “+” or “-“ of S1. When S1 is “+”, D2 will be On; when S1 is “-“, D2 will be
Off. D2 will not be Off immediately after the pulse output is over; it will be Off only when the drive contact of the
instruction turns Off.
9. For EH/EH2/SV/EH3/SV2 series MPU, S1 is
- The 32-bit data stored in the present value registers D1337 (high word) and D1336 (low word) of CH0 (Y0,
Y1).
- The 32-bit data stored in the present value registers D1339 (high word) and D1338 (low word) of CH1 (Y2,

- The 32-bit data stored in the present value registers D1378 (high word) and D1377 (low word) of CH3 (Y5,
Y6).
- When in backward direction, the content in the present value register will decrease.
10. For SC series MPU, S1 is the 32-bit data stored in the present value registers D1348 (low word) and D1349
(high word) of CH0 (Y10) or the 32-bit data stored in the present value registers D1350 (low word) and D1351
(high word) of CH1 (Y11). When in backward direction, the content in the present value register will decrease.
When the program goes from STOP to RUN or from RUN to STOP, the content in the present value register
will remain unchanged.
11. When DRVI instruction is executing pulse output, you cannot change the content of all operands. The changes
will be valid next time when DRVI instruction is enabled.
12. For EH/EH2/SV/EH3/SV2 series MPU, when the drive contact of DRVI instruction is Off, even the indication
flag M1336 sent by CH0 pulses, M1337 sent by CH1 pulses, M1522 sent by CH2 pulses and M1523 sent by
CH3 pulses are “On”, DRVI instruction will not be driven again.
13. When the absolute value of the input frequency of DDRVI insturction in EH/EH2/SV/EH3/SV2 series MPU is
larger than 200kHz, the output will be operated at 200kHz. When the absolute value of the input frequency is
smaller than 10Hz, the output will be operated at 10Hz.
14. D1343 (D1353) is for setting up the time of the first acceleartion segment and last deceleration segment of
CH0 (CH1). The acceleration and deceleration time of EH/EH2/SV/EH3/SV2 series MPU is 1 ~ 10,000ms. The
output will be operated for the default 100ms if the time is longer than 10,000ms. The time range for SC series
MPU is 50 ~ 20,000ms. The output will be operated for 20,000ms or 50ms if the time set is longer than
20,000ms or shorter than 50ms.
15. D1340 (D1352) is for setting up the start/end frequency of Y10 (Y11). If S2 is less than or equals start/end
frequency, the pulse output frequency will be executed by the start/end frequency.
16. For EH/EH2/SV/EH3/SV2 series MPU, M1305 (M1306) is the direction signal of CH0 (CH1). When S1 is a
positive number, the output will be operated in a forward direction and M1305 (M1306) will be Off. When S1 is
a negative number, the output will be operated in a backward direction and M1305 (M1306) will be On.
Program Example:
When M10= On, Y0 will output 20,000 pulses (relative designation) at 2kHz. Y5 = On indicates the pulses are
executed in forward direction.

c) Many DRVI instructions can be compiled synchronously in the program, but only one instruction can be
activated whenever the PLC executes the program. For example, if Y10 output has already been activated by
an instruction, other instructions that are also used to activate Y10 output will not be excecuted. Therefore,
the principle of the instruction activation sequence is “first activated, first executed”.
d) When Y10 is activated by DDRVI instruction, the output function of Y10 will be disabled until DDRVI is OFF.
The same rule applies to Y11.
e) Once the instruction is activated, all other parameters cannot be modified until the instruction is disabled.
f) When the instruction is disabled but the output has not yet completed:
M1334 = On indicates that Y10 will stop output immediately.
M1334 = Off indicates that Y10 will decelerate according to the deceleration time till it reaches end frequency
and stop the pulse output.
M1335 corresponds to Y11 output and applies the same rule.

Operands:
S1: Number of output pulses (absolute designation) S2: Pulse output frequency D1: Pulse output device
(please use transistor output module) D2: Output device for the signal of rotation direction
Explanations:
1. See remarks for the setting range of S1, S2, D1 and D2.
2. S1 and S2 of SC series MPU only support device K, H and D.
3. Flag: see remarks of API 158 DRVI for more details.
4. S1 is the number of output pulses (absolute designation). For EH/EH2/SV/EH3/SV2 series MPU, the 16-bit
instruction can designate the range -32,768 ~ +32,767. The range designated by 32-bit instruction is
-2,147,483,648 ~ +2,147,483,647. For SC series MPU, the 32-bit instruction can designate the range
-2,147,483,648 ~ +2,147,483,647. “+/-” signs indicate forward/backward directions.
5. S2 is the designated pulse output frequency. For EH/EH2/SV/EH3/SV2 series MPU, the 16-bit instruction can
designate its range 10 ~ 32,767Hz. The range designated by 32-bit instruction is 10 ~ 200,000Hz. For SC
series MPU, the 32-bit instruction can designate the range 100 ~ 100,000Hz.
6. EH series MPU has two groups of A/B phase pulse output, CH0 (Y0, Y1) and CH1 (Y2, Y3). EH2/SV series
MPU has four groups of A/B phase pulse output, CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4, Y5) and CH3 (Y6, Y7).
See remarks for the setup methods.
7. Pulse output device D1 in different models
Model SC MPU EH/EH2/SV/EH3/SV2 MPU
Pulse output end Y10, Y11 Y0, Y2
8. When S1 is larger than the current relative position, D2 will be Off; when S1 is smaller than the current relative
position, D2 will be On. D2 will not be Off immediately after the pulse output is over; it will be Off only when the
drive contact of the instruction turns Off.
9. For EH/EH2/SV/EH3/SV2 series MPU, S1 is
- The 32-bit data stored in the present value registers D1337 (high word) and D1336 (low word) of CH0 (Y0,
Y1).
- The 32-bit data stored in the present value registers D1339 (high word) and D1338 (low word) of CH1 (Y2,
Y3).
- The 32-bit data stored in the present value registers D1376 (high word) and D1375 (low word) of CH2 (Y4,
Y5).
9 Application Instructions API 150-199
DVP-PLC Application Manual
9-43
- The 32-bit data stored in the present value registers D1378 (high word) and D1377 (low word) of CH3 (Y5,
Y6).
When in backward direction, the content in the present value register will decrease.
10. For SC series MPU, S1 is the 32-bit data stored in the present value registers D1348 (low word) and D1349
(high word) of CH0 (Y10) or the 32-bit data stored in the present value registers D1350 (low word) and D1351
(high word) of CH1 (Y11). When in backward direction, the content in the present value register will decrease.
When the program goes from STOP to RUN or from RUN to STOP, the content in the present value register
will remain unchanged.
11. For EH/EH2/SV/EH3/SV2 series MPU, when DRVA instruction is executing pulse output, you cannot change
the content of all operands. The changes will be valid next time when DRVA instruction is enabled.
12. For EH/EH2/SV/EH3/SV2 series MPU, when the drive contact of DRVA instruction is Off, the pulse output will
decelerate to stop and M1029 and M1030 will be enabled. For SC series MPU, the pulse output will decelerate
to stop and M1102 and M1103 will be enabled.
13. For EH/EH2/SV/EH3/SV2 series MPU, when the drive contact of DRVA instruction is Off, even the indication
flag M1336 sent by CH0 pulses or M1337 sent by CH1 pulses are “On”, DRVA instruction will not be driven
again.
14. When the absolute value of the input frequency of DRVA and DDRVA insturctions in EH/EH2/SV/EH3/SV2
series MPU is larger than 200kHz, the output will be operated at 200kHz. When the absolute value of the input
frequency is smaller than 10Hz, the output will be operated at 10Hz.
15. D1343 (D1353) is for setting up the time of the first acceleartion segment and last deceleration segment of
CH0 (CH1). The acceleration and deceleration time of EH/EH2/SV/EH3/SV2 series MPU is 1 ~ 10,000ms. The
output will be operated for the default 100ms if the time is longer than 10,000ms. The time range for SC series
MPU is 50 ~ 20,000ms. The output will be operated for 20,000ms or 50ms if the time set is longer than
20,000ms or shorter than 50ms.
16. For EH/EH2/SV/EH3/SV2 series MPU, M1305 (M1306) is the direction signal of CH0 (CH1). When S1 is a
positive number, the output will be operated in a forward direction and M1305 (M1306) will be Off. When S1 is a
negative number, the output will be operated in a backward direction and M1305 (M1306) will be On.
17. D1340 (D1352) is for setting up the start/end frequency of Y10 (Y11). If S2 is less than or equals start/end
frequency, the pulse output frequency will be executed by the start/end frequency.
Program Example:
When M10= On, Y0 will output 20,000 pulses (absolute designation) at 2kHz. Y5 = On indicates the pulses are
executed in forward direction.

c) Many DRVA instructions can be compiled synchronously in the program, but only one instruction can be
activated whenever the PLC executes the program. For example, if Y10 output has already been activated
by an instruction, other instructions that are also used to activate Y10 output will not be excecuted.
Therefore, the principle of the instruction activation sequence is “first activated, first executed”.
d) When Y10 is activated by DDRVA instruction, the output function of Y10 will be disabled until DDRVAis OFF.
The same rule applies to Y11.
e) Once the instruction is activated, all other parameters cannot be modified until the instruction is disabled.
f) When the instruction is disabled but the output has not yet completed:
M1334 = On indicates that Y10 will stop output immediately.
M1334 = Off indicates that Y10 will decelerate according to the deceleration time till it reaches end frequency
and stop the pulse output.
M1335 corresponds to Y11 output and applies the same rule.

P0: position mode.
P1: using absolute value.
P21: pulse input type as Pulse+DIR.
(b) The forward/reverse limit switch should be connected to SERVO AMP.
(c) When using OP (Z-phase signal) in servo and given that the Z-phase signal is a high-frequency one when
the motor is running at high speed, the valid detection can only be possible when the signal is within the
range detectable by PLC. When using OP (Z phase signal) of the servo, if Z phase signal is a high
frequency signal during high-speed motor operation, the high frequency signal shall be within the available
range that can be detected by PLC.

7. Cautions when designing a position control program:
a) There is no limitation on the times of using the position control instructions, API 156 ZRN, API 157 PLSV,
API 158 DRVI, and API 159 DRVA. However, the user still have to note that:
i. Do not drive the position control instructions which use the same output CH0(Y0, Y1) or CH1(Y2, Y3)
simultaneously. Otherwise, they will be treated as repeated outputs and cannot function normally.
ii. It is recommended that you use the step ladder instruction (STL) to design the position control program
(see the example below).
b) How to use the position control instructions (API 156 ABSR, API 157 PLSV, API 158 DRVI, and API 159
DRVA) and pulse output instructions (API 57 PLSY, API 58 PWM and API 59 PLSR) at the same time.
The position control instruction and pulse output instruction share the 32 bits of the present value register
(D1337 high word; D1336 low word) of CH0 (Y0, Y1) or the present value register of CH1 (Y2, Y3), which will
make the operation complicated. Therefore, it is recommanded that you replace the pulse output instruction
with position control instruction.
c) Explanations on the (Y0, Y1) pulses from CH0 and (Y2, Y3) pulses from CH1.
Voltage range: DC5V ~ DC24V
Current range: 10mA ~ 100mA
Output pulse frequency: Y0, Y2 at 200kHz; Y1, Y3 at 10kHz.
8. Settings of pulse output signals in the operation of position control for EH/EH2/SV/EH3/SV2 series MPU:
a) Pulse + DIR (recommended)
Pulse
DI
R
b) CW/CCW (limited frequency at 10kHz)
CW
CCW
c) A/B-phase output (limited frequency at 10kHz)
A
B
9. Follow the above output settings of PLC for the pulse input parameters of SERVO AMP or stepping motor.
10. For EH/EH2/SV/EH3/SV2 series MPU, when Y0 output adopts many high-speed pulse output instructions
(PLSY, PWM, PLSR) and position control instructions (ZRN, PLSV, DRVI, DRVA) in a program and these
instructions are executed synchronously in the same scan period, PLC will execute the instruction with the
fewest step numbers.

Operands:
S: Period of time when D2 is On (in hour) D1: Current value being measured (in hour) D2: Output device
Explanations:
1. If S is used in device F, only 16-bit instruction is applicable.
2. D1 will occupy 2 consecutive points. D1 + 1 uses 16-bit register in 16-bit or 32-bit instruction.
3. See the specifications of each model for their range of use.
4. HOUR instruction can be used 4 times of SA/SX/SC.
5. Range of S: K1 ~ K32,767 (unit: hour); range of D1: K0 ~ K32,767 (unit: hour). D1 + 1 refers to the current time
that is less than an hour (range: K0 ~K3,599; unit: second).
6. This instruction times the time and when the time reaches the set time (in hour), D2 will be On. This function
allows the user to time the operation of the machine or conduct maintenance works.
7. After D2 is On, the timer will resume the timing.
8. In the 16-bit instruction, when the current time measured reaches the maximum 32,767 hours/3,599 seconds,
the timing will stop. To restart the timing, D1 and D1 + 1 have to be reset to “0”.
9. In the 32-bit instruction, when the current time measured reaches the maximum 2,147,483,647 hours/3,599
seconds, the timing will stop. To restart the timing, D1 ~ D1 + 2 have to be reset to “0”.
10. There is no limitations on the times of using this instruction in the program for EH series MPU; however, only 4
instructions can be executed at the same time.
Program Example 1:
In 16-bit instruction, when X0 = On, Y10 will be On and the timing will start. When the timing reaches 100 hours, Y0
will be On and D0 will record the current time measured (in hour) and D1 will record the current time that is less than

1. Explanations on the matrix instruction:
a) A matix consists of more than 1 consecutive 16-bit registers. The number of registers in the matrix is the

9-83
length of the array (n). A matrix contains 16 × n bits (points) and there is only 1 bit (point) offered for an
operand at a time.
b) The matrix instruction gathers a series of 16 × n bits (b0 ~ b16n-1) and designates a single point for operation.
The point will not be seen as a value.
c) The matrix instruction processes the moving, copying, comparing and searching of one-to-many or
many-to-many matrix status, which is a very handy and important application instruction.
d) The matrix operation will need a 16-bit register to designate a point among the 16n points in the matrix for the
operation. The register is the Pointer (Pr) of the matrix, designated by the user in the instruction. The vaild
range of Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix.
e) There are left displacement, right displacement and rotation in a matrix operation. The bit number decreases
from left to right (see the figure below).

4. See the specifications of each model for their range of use.
5. Flags: M1088 ~ M1092. See remarks for more details.
6. This instruction compares every bit in S1 with every bit in S2 starting from location D + 1 and finds out the
location of different bits. The location will be stored in D.
7. The matrix comparison flag (M1088) decides to compare between equivalent values (M1088 = 1) or different
values (M1088 = 0). When the comparison is completed, it will stop immediately and the matrix bit search flag
will turn “On” (M1091 = 1). When the comparison progresses to the last bit, the matrix search end flag (M1089)
will turn “On” and the No. where the comparison is completed is stored in D. The comparison will start from the
0th bit in the next scan period when the matrix search start flag turns “On” (M1090 = 1). When D exceeds the
range, the pointer error flag will turn “On” (M1092 = 1).
8. The matrix operation will need a 16-bit register to designate a point among the 16n points in the matrix for the
operation. The register is the Pointer (Pr) of the matrix, designated by the user in the instruction. The vaild
range of Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix. Please avoid changing the Pr value
during the operation in case the comparing and searching will not ne correct. If the Pr value exceeds its range,
M1092 will be On and the instruction will not be executed.
9. When M1089 and M1091 take place at the same time, both flags will be “1” at the same time.
Program Example:
1. When X0 goes from Off to On, the matrix search start falg M1090 = 0. The searching will start from the bit
marked with “*” (current Pr value +1) for bits of different status (M1088 = 0).
2. Set the Pr value D20 = 2. When X0 goes from Off to On for 4 times, we can obtain the 4 execution results n, o,
p, q.

4. See the specifications of each model for their range of use.
5. Flags: M1089 ~ M1095. See remarks for more details.
6. When this instruction is executed, it first determines if the matrix pointer clear flag (M1094) is “On”. If it is “On”,
pointer D is cleared as 0. The instruction then reads the On/Off status from the 0th bit of S to the matrix
rotation/displacement/output carry flag (M1095). Whenever finishing reading 1 bit, the instruction determines
whether the matrix pointer increasing flag (M1093) is “On”. If it is “On”, the value of pointer D will plus 1. When
the reading is processed to the last bit, the matrix search end flag (M1089) will turn “On” and pointer D record

6. When this instruction is executed, if first determines if the matrix pointer clear flag (M1094) is “On”, If it is “On”,
pointer D is cleared as 0. The instruction then writes the value in the matrix displacement/input complement
flag (M1096) into the location starting from the 0th bit of S. Whenever finishing writing 1 bit, the instruction
determines whether the matrix pointer increasing flag (M1093) is “On”. If it is “On”, the value of pointer D will

Explanations:
1. Range of n: K1 ~ K256
2. S designates KnX, KnY, KnM and KnS; D designates KnY, KnM and KnS.
3. SA/SX/SC can designate n = 4. EH/EH2/SV/EH3/SV2 can designate n 4≦.
4. See the specifications of each model for their range of use.
5. Flags: M1095 ~ M1097. See remarks for more details.
6. This instruction performs left-right displacement on the matrix bits in S according to array length n. M1097
determines the left (M1097 = 0) or right (M1097 = 1) displacement of matrix bits. The empty bits derived from
every displacement of 1 bit (when left displacement: b0; when right displacement: b16n-1) is filled by the status of
the complement flag (M1096). The spare bits (when left displacement: b16n-1; when right displacement: b0) are
sent to the carry flag (M1095). The result is stored in D.
7. The pulse execution instruction MBSP is generally adopted.
Program Example 1:
When X0 = On, M1097 = Off, indicating a left matrix displacement is performed. Set M1096 = 0 and the 16-bit
registers D0 ~ D2 will perform a left matrix displacement and the result will be stored in the matrix of the 16-bit
registers D20 ~ D22. The carry flag M1095 will be “1”.

S: Max. point to point output frequency D: Pulse output device
Explanations:
1. Flags: M1029, M1030, M1334, M1335. See remarks for more details.
2. This instruction only supports EH2/SV/EH3/SV2 series MPU, not EH series. In terms of pulse output methods,
this instructin only supports “pulse + direction” mode.
3. S1 and S2 are the designated (relative designation) number of output pulses in X axis (Y0 or Y4) and Y axis (Y2
or Y6). The range of the number is -2,147,483,648 ~ +2,147,483,647 (+/- represents the forward/backward
direction). When in forward direction, the pulse present value registers CH0 (D1337 high word, D1336 low word),
CH1 (D1339 high word, D1338 low word), CH2 (D1376 high word, D1375 low word) and CH3 (D1378 high word,
D1377 low word) will increase. When in backward direction, the present value will decrease.
4. D can designate Y0 and Y4.
When Y0 is designated:
Y0 refers to 1st group X-axis pulse output device.
Y1 refers to 1st group X-axis direction signal.
Y2 refers to 1st group Y-axis pulse output device.
Y3 refers to 1st group Y-axis direction signal.
Y4 refers to 2nd group X-axis pulse output device.
Y5 refers to 2nd group X-axis direction signal.
Y6 refers to 2nd group Y-axis pulse output device.
Y7 refers to 2nd group Y-axis direction signal.
When direction signal outputs, Off will not occur immediately after the pulse output is over. Direction signal will
turn Off when the drive contact is Off.
5. D1340 (D1379) refers to the settings of the start/end frequencies of the 1st/2nd 2-axis motion. D1343 (D1381)
refers to the time of the first acceleration segment and last deceleration segment of the 1st/2nd 2-axis motion.
The time shall be longer than 10ms. If the time is shorter than 10ms or longer than 10,000ms, the output will be
operated at 10ms. Default setting = 100ms.
6. If the maximum output frequency setting is less than 10Hz, the output will be operated at 10Hz. If the setting is
9 Application Instructions API 150-199
DVP-PLC Application Manual
9-100
more than 200kHz, the output will be operated at 200kHz.
7. When the 2-axis synchronous motion instruction is enabled, the start frequency and acceleration/deceleration
time in Y axis will be same as the settings in X axis.
8. The number of output pulses for the 2-axis motion shall not be less than 59; otherwise the line drawn will not be
straight enough.
9. There is no limitation on the number of times using the instruction. However, assume CH1 or CH2 output is in
use, the 1st group X/Y axis will not be able to output. If CH3 or CH4 output is in use, the 2nd group X/Y axis will
not be able to output.
Program Example:

2. Steps:
a) Set the four coordinates (0,0), (-27000, -27000), (0, -55000), (27000, -27000) (as the figure above). Calculate the
relative coordinates of the four points and obtain (-27000, -27000), (27000, -28000), (27000, 27000), and (-27000,
27000). Place them in the 32-bit (D200, D202), (D204, D206), (D208, D210), (D212, D214).
b) Write program codes as follows.

CH1 (D1339 high word, D1338 low word), CH2 (D1376 high word, D1375 low word) and CH3 (D1378 high word,
D1377 low word) will increase. When in backward direction, the present value will decrease.
4. The lower 16 bits of S (settings of direction and resolution): K0 refers to clockwise 10-segment (average
resolution) output; K2 refers to clockwise 20-segment (higher resolution) output and a 90° arc can be drawn (see
figure 1 and 2). K1 refers to counterclockwise 10-segment (average resolution) output; K3 refers to
counterclockwise 20-segment (higher resolution) output and a 90° arc can be drawn (see figure 3 and 4).
5. The higher 16 bits of S (settings of motion time): K1 refers to 0.1 second. The setting range for average resolution
is K1 ~ K100 (0.1 sec. ~ 10 secs.), for higher resolution is K2 ~ K200 (0.2 sec. ~ 20 secs.) This instruction is
restricted by the maximum pulse output frequency; therefore when the set time goes faster than the actual output
time, the set time will be automatically modified.

9. When the 2-axis motion is being executed in 10 segments (of average resolution), the operation time of the
instruction when the instruction is first enabled is approximately 5ms. The number of output pulses cannot be less
than 100 and more than 1,000,000; otherwise, the instruction cannot be enabled.
10. When the 2-axis motion is being executed in 20 segments (of high resolution), the operation time of the
instruction when the instruction is first enabled is approximately 10ms. The number of output pulses cannot be

less than 1,000 and more than 10,000,000; otherwise, the instruction cannot be enabled.
11. If you wish the number of pulses in 10-segment or 20-segment motion to be off the range, you may adjust the
gear ratio of the servo for obtaining your desired number.
12. Every time when the instruction is executed, only one 90° arc can be drawn. It is not necessary that the arc has to
be a precise arc, i.e. the numbers of output pulses in X and Y axes can be different.
13. There are no settings of start frequency and acceleration/deceleration time.
14. There is no limitation on the number of times using the instruction. However, assume CH1 or CH2 output is in use,
the 1st group X/Y axis will not be able to output. If CH3 or CH4 output is in use, the 2nd group X/Y axis will not be
able to output.
15. The settings of direction and resolution in the lower 16 bits of S can only be K0 ~ K3.
16. The settings of motion time in the high 16 bits of S can be slower than the the fastest suggested time but shall not

Explanations:
1. Flags: M1029, M1030, M1334, M1335. See remarks of API 191 DPPMR for more details.
2. This instruction only supports EH2/SV/EH3/SV2 series MPU, not EH series. In terms of pulse output methods,
this instructin only supports “pulse + direction” mode.
3. S1 and S2 are the designated (absolute designation) number of output pulses in X axis (Y0 or Y4) and Y axis (Y2
or Y6). The range of the number is -2,147,483,648 ~ +2,147,483,647. When S1 and S2 are larger than pulse
present value registers CH0 (D1337 high word, D1336 low word), CH1 (D1339 high word, D1338 low word), CH2
(D1376 high word, D1375 low word), and CH3 (D1378 high word, D1377 low word), the output direction will be
positive and direction signals Y1, Y3, Y5, Y7 will be On. When S1 and S2 are less than pulse present value
registers, the output direction will be negative and direction signals Y1, Y3, Y5, Y7 will be Off.
4. The lower 16 bits of S (settings of direction and resolution): K0 refers to clockwise 10-segment (average
resolution) output; K2 refers to clockwise 20-segment (higher resolution) output and a 90° arc can be drawn (see
figure 1 and 2). K1 refers to counterclockwise 10-segment (average resolution) output; K3 refers to
counterclockwise 20-segment (higher resolution) output and a 90° arc can be drawn (see figure 3 and 4).
5. The higher 16 bits of S (settings of motion time): K0 refers to 0.1 second. The setting range for average resolution
is K1 ~ K100 (0.1 sec. ~ 10 secs.), for higher resolution is K2 ~ K200 (0.2 sec. ~ 20 secs.) This instruction is
restricted by the maximum pulse output frequency; therefore when the set time goes faster than the actual output
time, the set time will be automatically modified.

2. This instruction only supports EH2/SV/EH3/SV2 series MPU, not EH series.
3. According to the value of S2 + 0, every segment consecutively occupy four register D. (S1 + 0) refers to output
frequency. (S1 + 2) refers to the number of output pulses.
4. When the output frequency of S1 is less than 1, PLC will automatically modify it as 1. When the value is larger
than 200,000kHz, PLC will automatically modify it as 200,000kHz.
5. S2 + 0: number of segments (range: 1 ~ 60). S2 + 1: number of segments being executed. Whenever the program
scans to this instruction, the instruction will automatically update the segment No. that is currently being
executed.
6. D can only designate output devices Y0, Y2, Y4 and Y6 and can only perform pulse output control. For the pin for
direction control, the user has to compile other programs to control.
7. This instruction does not offer acceleration and deceleration functions. Therefore, when the instruction is disabled,
the output pulses will stop immediately.
8. In every program scan, each channel can only be executed by one instruction. However, there is no limitation on
the number of times using this instruction.
9. When the instruction is being executed, the user is not allowed to update the frequency or number of the
segments. Changes made will not be able to make changes in the actual output.

D: Pulse output device
Explanations:
1. Flags: M1029, M1030, M1334, M1335. See remarks for more details.
2. This instruction only supports EH2/SV/EH3/SV2 series MPU, not EH series.
3. The corresponding interruption of S1:

Interruption No. I00 I10 I20 I30 I010 I020 I030 I040
= 1: rising-edige trigger; = 0: falling-edge trigger
a) When S1 designates X as the input points and the pulse output reaches the set target number of feedbacks
in S2, the output will continue to operate by the frequency of the last segment until the interruption of X input
points occurs.
b) When S1 designates a high speed counter and the pulse output reaches the set target number of feedbacks
in S2, the output will continue to operate by the frequency of the last segment until the feedback pulses
reaches the target number.
c) S1 can be a high speed counter C or an external interruption X. If S1 is C, DCNT instruction should be first
executed to enable the high-speed counting function and EI and I0x0 interruption service program to enable
the high-speed interruption. If S1 is X, EI instruction and I0x0 interruption service program should be
executed to enable the external interruption function.
4. The range of S2: -2,147,483,648 ~ +2,147,483,647 (+/- represents the forward/backward direction). When in
forward direction, the pulse present value registers CH0 (D1337 high word, D1336 low word), CH1 (D1339 high
word, D1338 low word), CH2 (D1376 high word, D1375 low word) and CH3 (D1378 high word, D1377 low word)
will increase. When in backward direction, the present value will decrease.
5. If S3 is lower than 10Hz, the output will operate at 10Hz; if S3 is higher than 200kHz, the output will operate at
200kHz.
6. D can only designate Y0, Y2, Y4 and Y6 and the direction signals repectively are Y1, Y3, Y5 and Y7. When
there is a direction signal output, the direction signal will not be Off immediately after the pulse output is

DVP-PLC Application Manual
9-120
completed. The direction signal will be Off only when the drive contact is Off.
7. D1340, D1352, D1379 and D1380 are the settings of start/end frequencies of CH0 ~ CH3. The minimun
frequency is 10Hz and default is 200Hz.
8. D1343, D1353, D1381 and D1382 are the settings of the time of the first segment and the last deceleration
segment of CH0 ~ CH3. The acceleration/deceleration time cannot be shorter than 10ms. The outptu will be
operated in 10ms if the time set is shorter than 10ms or longer than 10,000ms. The dafault setting is 100ms.
9. D1131, D1132, D1478 and D1479 are the output/input ratio of the close loop control in CH0 ~ CH3. K1 refers to
1 output pulse out of the 100 target feedback input pulses; K200 refers to 200 output pulses out of the 100
target feedback input pulses. D1131, D1132, D1478 and D1479 are the numerators of the ratio (range: K1 ~
K10,000) and the denominator is fixed as K100 (the user does not have to enter a denominator).
10. M1305, M1306, M1532 and M1533 are the direction signal flags for CH0 ~ CH3. When S2 is a positive value,
the output will be in forward direction and the flag will be Off. When S2 is a negative value, the output will be in
backward direction and the flag will be On.
Close Loop Explanations:
1. Function: Immediately stop the high-speed pulse output according to the number of feedback pulses or external
interruption signals.
2. The execution:
Frequency
Time
Number
C high speed counting = target number of feedbacks
or
occurrence of external interruption
Target frequency
Start/end frequency
Acceleration
time
High speed time Deceleration time
Idling time
Number of output pulses =
target number of feedbacks x percentage value/100
3. How to adjust the time for the completion of the positioning:
a) The time for the completion of the positioning refers to the time for “acceleration + high speed +
deceleration + idling” (see the figure above). For example, you can increase or decrease the entire number
of output pulses by making adjustment on the percentage value and further increase or decrease the time
required for the positioning.
b) Among the four segments of time, only the idling time cannot be adjusted directly by the user. However, you
can determine if the execution result is good or bad by the length of the idling time. In theory, a bit of idling
left is the best result for a positioning.
c) Owing to the close loop operation, the length of idling time will not be the same in every execution.
Therefore, when the content in the special D for displaying the actial number of output pulses is smaller or
larger than the calculated number of output pulses (taget number of feedbacks x percentage value/100),
9 Application Instructions API 150-199

you can improve the situation by adjusting the percentage value, acceleration/decelartion time or target
frequency.
Program Example:
1. Assume we adopt X0 as the external interruption, together with I001 (rising-edge trigger) interruption program;
target number of feedbacks = 50,000; target frequency = 10kHz; Y0, Y1 (CH0) as output pulses; start/end
frequency (D1340) = 200Hz; acceleration time (D1343) = 300ms; deceleration time (D1348) = 600ms;
percentage value (D1131) = 100; current number of output pulses (D1336, D1337) = 0.

to 0 before the execution); target number of feedbacks = 50,000; target output frequency = 100kHz; Y0, Y1
(CH0) as output pulses; start/end frequency (D1340) = 200Hz; acceleration time (D1343) = 300ms; deceleration
time (D1348) = 600ms; precentage value (D1131) = 100; current number of output pulses (D1336, D1337) = 0.

Operands:
S1: Target frequency of output S2: Target number of pulses S3: Gap time and gap frequency
D: Pulse output device (Y0, Y2, Y4, Y6)
Explanations:
1. The instruciton only supports V2.0 of EH2 series. It does not support EH/SV series.
2. Max frequency for S1: 100kHz. Target frequency can be modified during the execution of instruction. When S1 is
modified, VSPO will ramp up/down to the target frequency according to the ramp-up gap time and gap
frequency set in S3.
3. S2 target number of pulses is valid only when the instruction is executed first time. S2 can NOT be modified
during the execution of instruction. S2 can be a negative value. When target number of pulses are specified with
0, PLC will perform continuous output.
4. S3 occupies 2 consecutive 16-bit devices. S3+0 stores the gap frequency S3+1 stores the gap time. Parameter
setting can be modified during the execution of instruction. Set range for S3+0: 6Hz ~ 32767Hz; set range for
S3+0: 1ms ~ 80ms. If set value exceeds the available range, PLC will take the upper or lower bound value.
5. D pulse output device supports Y0, Y2, Y4 and Y6. Y1, Y3, Y5 and Y7 are corresponding output direction. The
positive direction is On.
6. Parameters set in S3 can only be modified while modifying the value in S1. When target frequency is set as 0,
PLC will ramp down to stop according to parameters set in S3. When the output is stopped, PLC will enable the
flags indicating pause status (CH0: M1538; CH1: M1539; CH2: M1540; CH3: M1541). If target frequency other
than 0 is specified again, pulse output will ramp up to target frequency and operates untill target number of
pulses are completed.

Operands:
S1: Target frequency to be changed S2: Gap time and gap frequency D: Pulse output device (Y0, Y2)
Explanations:
1. The instruciton only supports V2.0 of EH2 series. It does not support EH/SV series.
2. Max frequency for S1: 100kHz. When ICF instruction executes, frequecy changing will start immediately with
ramp-up/down process.
3. ICF instruction has to be executed after the execution of DVSPO or DPLSY instructions. When the instruction is
used together with DVSPO, operands S1, S2, D of DICF has to be assigned the same device with S1, S3, D of
DVSPO. When the instruction is used with DPLSY, operands S1 and D has to be assigned the same device with
S1 and D of DPLSY.
4. If ICF instruction is used with DPLSY instruction, operand S2 is invalid.
5. When ICF instruction is used with DVSPO instruction, parameter setting of S2 functions the same as S3 in
DVSPO instruction, specifying the gap time and gap frequency of ramp-up/down process.
6. D pulse output device supports only Y0 and Y2.
7. The instruction is suggested to be applied in interrupt subroutines for obtaining the better response time and
execution results
8. For associated flags and registers, please refer to Points to note of API 198 DVSPO instruction.
Function Explanations:
1. If users change the target frequency by using DVSPO instruction, the actual changing timing will be delayed due
to the program scan time and the gap time as below.

Program Example:

Calculation of total shifts: (100,000 ﹣0) ÷ 1000 = 100.
2. When X6 external interrupt executes, target frequency is changed and ramp down to 50kHz immediately. Total
shifts: 150, Gap frequency: 800Hz, Gap time: 20ms. Calculation of total shifts: (100,000 ﹣50,000) ÷ 800 = 125
3. When X7 external interrupt executes, target frequency is changed and ramp down to 100Hz immediately. Total
shifts: 25, Gap frequency: 2000Hz, Gap time: 100ms. Calculation of total shifts: (50,000 ﹣100) ÷ 2000 = 25.
4. When pulse output reaches 100Hz, the frequency is kept constant and pulse output stops when 1,000,000 pulses
is completed.

Operands:
S1: Source device 1 S2: Source device 2 n: Data length/function D: Destination device
Explanations:
1. EH2/SV_V1.9 and versions above, and EH3/SV2 support the 16-bit instruction. EH3_V1.20 and version above,
and SV2 support the 32-bit instruction.
2. S1 and S2 can be T/C/D devices, for C devices only 16-bit devices are applicable (C0~C199).
3. The high 16-bit value in the operand n used in the 32-bit instruction is an invalid value.
4. The low 8-bit value in the operand n indicates the data length. The operand n used in the 16-bit instruction
should be within the range between 1 and 16. The operand n used in the 32-bit instruction should be within the
range between 1 and 32. PLC will take the upper/lower bound value if set value exceeds the available range.
5. The high 8-bit value in the operand n indicates the comparison condition.
Value K0 K1 K2 K3 K4
Comparison condition S1 = S2 S1 < S2 S1 <= S2 S1 > S2 S1 >= S2
6. If n used in the 16-bit instruction is set to H0108, it means that 8 pieces of data are compared to 8 pieces of data,
and the “larger than” comparison is performed. If n used in the 32-bit instruction is set to H00000320, it means
that 32 pieces data are compared to 32 pieces of data, and the “less than” comparison is performed.
7. If the setting value for the comparison condition exceeds the range, or the firmware version does not support the
comparison condition, the default “equal to” comparison is performed. EH3_V1.20 and version above, and SV2
and versions above support the setting value for the comparison condition.
8. The comparison values used in the 16-bit instruction are signed values. The comparison values used in the
32-bit instruction are 32-bit values (M1162=Off), or floating-point values (M1162=On).
9. Data written in operand D will all be stored in 16-bit format or in 32-bit format. When data length is less than 16
or 32, the null bits are fixed as 0, e.g. if n = K8, bit 0~7 will be set according to compare results, and bit 8~15 will
all be 0.
10. If the comparison result meets the condition, the corresponding bit is set to 1. Otherwise, it is set to 0.
Program example:
When M0 = ON, compare the 16-bit value in D0~D7 with D20~D27 and store the results in D100.

CSFO: 7 steps
PULSE 16-bit 32-bit
ES EX SS SA SX SC EH SV EH3 ES EX SS SA SX SC EH SV EH3 ES EX SS SA SX SC EH SV EH3
Operands:
S: Source device of signal input (Only X0~X3 are available)
S1: Sample time setting and the input speed information
D: Output proportion setting and output speed information
Explanations:
1. When S specifies X0, PLC only uses X0 input point and its associated high speed pulse output: Y0, in this case
Y1 is normal output point. When S specifies X1, PLC uses X0 (A phase) and X1 (B phase) input points and their
associated output: Y0 (Pulse) / Y1 (Dir).
2. The execution of CSFO requires hardware high speed counter function as well as the high speed output
function. Therefore, when program scan proceeds to CSFO instruction with high speed counter input points (X0,
X1) enabled by DCNT instruction, or high speed pulse outputs (Y0, Y1) enabled by other high speed output
instructions, CSFO instruction will not be activated.
3. If S specifies X1 with 2-phase 2 inputs, the counting mode is fixed as quadruple frequency.
4. During pulse output process of Y0, special registers (D1337, D1336) storing the current number of output pulses
will be updated when program scan proceeds to this instruction.
5. S1 occupies consecutive 4 16-bit registers. S1 +0 specifies the sampling times, i.e. when S1 +0 specifies K1,
PLC catches the speed every time when 1 pulse is outputted. Valid range for S1 +0 in 1-phase 1-input mode:
K1~K100, and 2-phase 2-input mode: K2~K100. If the specified value exceeds the valid range, PLC will take the
lower/upper bound value as the set value. Sample time can be changed during PLC operation, however the
modified value will take effect until program scan proceeds to this instruction. S1+1 indicates the latest speed
sampled by PLC (Read-only). Unit: 1Hz. Valid range: ±10kHz. S1+2 and S1+3 indicate the accumulated number
of pulses in 32-bit data (Read-only).
6. For single phase input, the max frequency is 10kHz; for 2-phase 2 inputs, the max frequency is 2kHz.
7. D occupies 3 consecutive 16-bit registers. D +0 specifies the output proportion value. Valid range: K1 (1%) ~
K10000 (10000%). If the specified value exceeds the valid range, PLC will take the lower/upper bound value as
the set value. Output proportion can be changed during PLC operation, however the modified value will take
effect until program scan proceeds to this instruction. D+2 and D+1 indicates the output speed in 32-bit data.
Unit: 1Hz. Valid range: ±100kHz.
8. The speed sampled by PLC will be multiplied with the output proportion D+0, then PLC will generate the actual
output speed. PLC will take the integer of the calculated value, i.e. if the calculated result is smaller than 1Hz,
10 Application Instructions API 200-249
DVP-PLC Application Manual
10-14
PLC will output with 0Hz. For example, input speed: 10Hz, output proportion: K5 (5%), then the calculation
result will be 10 x 0.05 = 0.5Hz. Pulse output will be 0Hz; if output proportion is modified as K15 (15%), then the
calculation result will be 10 x 0.15 = 1.5Hz. Pulse output will be 1Hz.
Program Example:
1. If D0 is set as K2, D10 is set as K100:
When the sampled speed on (X0, X1) is +10Hz (D1 = K10), (Y0, Y1) will output pulses with +10Hz (D12, D11 =
K10); When the sampled speed is -10Hz (D1 = K-10), (Y0, Y1) will output pulses with -10Hz (D12, D11 = K-10)
2. If D0 is set as K2, D10 is set as K1000:
When the sampled speed on (X0, X1) is +10Hz (D1 = K10), (Y0, Y1) will output pulses with +100Hz (D12, D11 =
K100); When the sampled speed is -100Hz (D1 = K-100), (Y0, Y1) will output pulses with -100Hz (D12, D11 =
K-100)
3. If D0 is set as K10, D10 is set as K10:
When the sampled speed on (X0, X1) is +10Hz (D1 = K10), (Y0, Y1) will output pulses with +1Hz (D12, D11 =
K1); When the sampled speed is -10Hz (D1 = K-10), (Y0, Y1) will output pulses with -1Hz (D12, D11 = K-1)

1. EH2/SV_V1.9 and versions above, and EH3/SV2 supports the function. EH series does not support the
dunction.
2. This instruction compares the content in S1 and S2. Take API281 (FAND =) for example, if the result is “=”, the
continuity of the instruction is enabled. If the result is “≠”, the continuity of the instruction is disabled.

11.1 Appendix A: Table for Self-Detecting Abnormality
When you encounter abnormality using the product, you can analyze the problem first by doing the self
detections below.
Abnormality Possible cause Suggested correction
Loosened terminal block Check if the removable terminal block is
loosened.
Output point abnormality The input counting specification may not
match the pulse output frequency of the
PLC model in use.
Check if the hardware is normal by
low-frequency pulse counting.
The length of communication cable
Make sure the RS-232 cable is at least 3
meters long to ensure normal
communication (specification unknown).
Communication
abnormality Incorrect communication protocol or
address setting
Broadcast from station 0 first by RS-232
to search for communication protocol and
address and later confirm by RS-485
communication.
Extension module unable
to work Poor connection or MPU problem
Make sure the MPU is tightly connected
to the extension module and compare to
make sure whether the problem lies in
the MPU or the extension module.
Counter (input point)
abnormality
The applicable frequency exceeds the
maximum bandwidth.
The frequency should be within the
allowed PLC specifications.
ERROR LED flashes Incorrect program syntax
Record the error code first, and write
whether the ERROR LED should not
flash anymore by syntactically correct
program. Model with battery should be
checked whether the time of RTC is
correct (not being correct means the
battery might once be unattached,
causing reset of time).
L.V. LED On Low input power supply Make sure the power supply voltage is
normal.
RUN LED Off after
execution
There is no program inside the new
PLC, resulting in misjudgment. Write in the program first.

DVP-PLC Application Manual 11-9
11.4 Appendix D: Difference between EH2 and EH3
The capacity of the program is upgraded to 30k Steps, and the number of D devices is increased to 12000.
The capacity of the memory card has doubled. To prevent the wrong insertion, the new memory card and the old
one are not interchangeable
Some function cards of DVP-EH2 can not be used in DVP-EH3. The function cards which can be used are all
communication cards, 02AD card and 02DA card.
When the position of the basic instruction is below 16k Step, the execution speed does not make any change.
When its position is above 16k Step, the execution speed becomes 2.8μs.
The execution speed of MOV instruction is improved to 4.8μs, and that of other application instructions is also
improved by 4~5 times.
The high-speed input/output functions of DVP-EH3
A. The number of external input interruptions is 16. (Please refer to section 2.1.)
B. There are 3 sets of masking functions of the interruption. (Please refer to section 2.11.)
C. Newly added CSFO instruction has the speed-tracing function and can be used with the manual pulse
generator. (Please refer to API 207.)
D. Newly added DVSPO and DICF instructions have various speed-changing functions. (Please refer to API
198 and API 199.)
E. The zero return instruction (DZRN) has the function of detecting limit switches, stopping at the positive
position, seeking Z phase, and outputting the displacement. (Please refer to API 156.)
F. The direction outputs of DZRN instruction are used with Y1, Y3, Y5, and Y7. (Please refer to API 156.)
G. That special M can set the start and reset functions of C235~C240 is cancelled. The bandwidth of
C235~C240can be up to 10 KHz.
Other newly added functions of DVP-EH3
A. COM1 card and COM3 card can be masters. COM3 is an independent communication port which does not
occupy COM2. The flag of the transmitting function in the master is the same as that in DVP-ES2.
B. The solar energy instructions DSPA and GPS instruction are added. (Please refer to API 177 and API
178)。
C. We add the m servo convenience instruction ASDRW.(Please refer to API 206.)
D. The program can be automatically backuped, and will not disappear even if the battery has run down.
E. The second-backup function can store the second program and data.
F. We add the basic instructions which are used exclusively for words. For example, BLD, BOUT, and etc.
(Please refer to API 266~274)
G. The comparison instruction of the floating point number (FLD>=….).is added. (Please refer to API
275~292)
H. M1356 can be used in PLC-LINK to designate the station numbers. Only when M1353 is on can
D1900~D1931 be used.
I. ISPSoft and WPLSoft can set the read-only function of the communication and function of downloading the
program.
J. It can connect with at most 12 right-side analog extension modules.
