1.1
PLC Scan Method
PLC utilizes a standard scan method when evaluating user program.
Scanning process:
Scan input status
Read the physical input status and store the data in internal
memory.
Evaluate user program
Evaluate the user program with data stored in internal memory.
Program scanning starts from up to down and left to right until
reaching the end of the program.
Refresh the outputs
Write the evaluated data to the physical outputs
Input signal
Input X
Input signal:
PLC reads the ON/OFF status of each input and
stores the status into memory before evaluating
the user program.
Input terminal
Store to memory
Input signal memory
Read X0 status from memory
Program
Y0
Read Y0 state from memory
Y0
M0
Write M0 state into
Output
Output
Output latched memory
Output terminal
Device Memory
Write Y0 state into
X0
Once the external input status is stored into
internal memory, any change at the external
inputs will not be updated until next scan cycle
starts.
Program:
PLC executes instructions in user program from
top to down and left to right then stores the
evaluated data into internal memory. Some of this
memory is latched.
Output:
When END command is reached the program
evaluation is complete. The output memory is
transferred to the external physical outputs.
Output Y
Scan time
The duration of the full scan cycle (read, evaluate, write) is called “scan time.” With more I/O or
longer program, scan time becomes longer.
1-2
Read
scan time
PLC measures its own scan time and stores the value (0.1ms) in register
D1010, minimum scan time in register D1011, and maximum scan time in
register D1012.
Measure
scan time
Scan time can also be measured by toggling an output every scan and then
measuring the pulse width on the output being toggled.
Calculate
scan time
Scan time can be calculated by adding the known time required for each
instruction in the user program. For scan time information of individual
instruction please refer to Ch3 in this manual.
1 . P L C C o n c e p ts
Scan time exception
PLC can process certain items faster than the scan time. Some of these items interrupts and halt
the scan time to process the interrupt subroutine program. A direct I/O refresh instruction REF
allows the PLC to access I/O immediately during user program evaluation instead of waiting until
the next scan cycle.
1.2
Current Flow
Ladder logic follows a left to right principle. In the example below, the current flows through paths
started from either X0 or X3.
X1

Reverse Current
When a current flows from right to left, which makes a reverse current logic, an error will be
detected when compiling the program. The example below shows the reverse current flow.

Bit memory indicates PLC status in Step Function Control (SFC) mode. If no
STL instruction is applied in program, step point S can be used as an internal
relay M as well as an annunciator.
Device indication: Indicated as S and numbered in decimal, e.g. S0, S1,
S2…S1023
T
(Relay)
(Word)
(Dword)
Bit, word or double word memory used for timing and has coil, contact and
register in it. When its coil is ON and the set time is reached, the associated
contact will be energized. Every timer has its resolution (unit:
1ms/10ms/100ms).
Device indication: Indicated as T and numbered in decimal, e.g. T0, T1,
T2…T255
C
(Counter)
(Relay)
(Word)
(Dword)
Bit, word or double word memory used for counting and has coil, contact and
register in it. The counter count once (1 pulse) when the coil goes from OFF to
ON. When the predefined counter value is reached, the associated contact will
be energized. There are 16-bit and 32-bit high-speed counters available for
users.
Device indication: Indicated as C and numbered in decimal, e.g. C0, C1,
C2…C255
D
(Data register)
(Word)
Word memory stores values and parameters for data operations. Every
register is able to store a word (16-bit binary value). A double word will occupy
2 consecutive data registers.
Device indication: Indicated as D and numbered in decimal, e.g. D0, D1,
D2…D4999
E, F
(Index register)
(Word)
Word memory used as a modifier to indicate a specified device (word and
double word) by defining an offset. Index registers not used as a modifier can
be used as general purpose register.
Device indication: indicated as E0 ~ E7 and F0 ~ F7.

1.5.1 Creating a PLC Ladder Program
The editing of the program should start from the left side bus line to the right side bus line, and from
up to down. However, the right side bus line is omitted when editing in WPLSoft. A single row can
have maximum 11 contacts on it. If more than 11 contacts are connected, a continuous symbol “0”
will be generated automatically and the 12th contact will be placed at the start of next row. The
same input points can be used repeatedly. See the figure below:
X0

When evaluating the user program, PLC scan starts from left to right and proceeds to next row
down until the PLC reaches END instruction. Output coils and basic / application instructions
belong to the output process and are placed at the right of ladder diagram. The sample program
below explains the execution order of a ladder diagram. The numbers in the black circles indicate
the execution order.

Description
Start of branches. Stores current result of
program evaluation. Max. 8 MPS-MPP pairs can
be applied
Reads the stored current result from previous
MPS
End of branches. Pops (reads then resets) the
stored result in previous MPS
Note: When compiling ladder diagram with WPLSoft, MPS, MRD and MPP could be automatically
added to the compiled results in instruction format. However, sometimes the branch instructions
are ignored by WPLSoft if not necessary. Users programming in instruction format can enter branch
instructions as required.

Note: Ladder diagram editor in ISPSoft does not support MPS, MRD and MPP instructions. To
achieve the same results as branch instructions, users have to connect all branches to the left
hand bus bar.

1.5.11 STL (Step Ladder Programming)
STL programming uses step points, e.g. S0 S21, S22, which allow users to program in a clearer
and understandable way as drawing a flow chart. The program will proceed to next step only if the
previous step is completed, therefore it forms a sequential control process similar to SFC
(Sequential Function Chart) mode. The STL sequence can be converted into a PLC ladder diagram
which is called “step ladder diagram” as below.

Fuzzy Syntax
Generally, the ladder diagram programming is conducted according to the “up to down and left to
right” principle. However, some programming methods not following this principle still perform the
same control results. Here are some examples explaining this kind of “fuzzy syntax.”
Example 1:
X0

X4
X1

X5
Better method
OK method

OR

X5
ANB
LD
X4
OR
OR
X5
ANB
ANB
ANB
The two instruction programs can be converted into the same ladder diagram. The difference
between Better and OK method is the ANB operation conducted by MPU. ANB instruction cannot
be used continuously for more than 8 times. If more than 8 ANB instructions are used continuously,
program error will occur. Therefore, apply ANB instruction after a block is made is the better
method to prevent the possible errors. In addition, it’s also the more logical and clearer
programming method for general users.
Example 2:
Good method

The difference between Good and Bad method is very clear. With longer program code, the
required MPU operation memory increases in the Bad method. To sum up, following the general
principle and applying good / better method when editing programs prevents possible errors and
improves program execution speed as well.
Common Programming Errors
PLC processes the diagram program from up to down and left to right. When editing ladder
diagram users should adopt this principle as well otherwise an error would be detected by WPLSoft
when compiling user program. Common program errors are listed below:

Basic Program Design Examples
Example 1 - Stop First latched circuit
Y1
When X1 (START) = ON and X2 (STOP) = OFF, Y1 will be ON.
If X2 is turned on, Y1 will be OFF. This is a Stop First circuit
because STOP button has the control priority than START

Example 2 - Start First latched circuit

Y1
When X1 (START) = ON and X2 (STOP) = OFF, Y1 will be ON
and latched. If X2 is turned ON, Y1 remains ON. This is a Start
First circuit because START button has the control priority than
STOP
Y1
Example 3 - Latched circuit of SET and RST
The diagram opposite are latched circuits consist of RST and
SET instructions.

In PLC processing principle, the instruction close to the end of Start first
the program determines the final output status of Y1. Therefore,
X2
if both X1 and X2 are ON, RST which is lower than SET forms a
X1
Stop First circuit while SET which is lower than RST forms a
Start First circuit.

Example 4 - Power down latched circuit

retains its status before power down and resumes after power

NC contact Y1 is connected to Y2 output circuit and NC contact Y2 is connected Y1 output circuit.
If Y1 is ON, Y2 will definitely be OFF and vice versa. This forms an Interlock circuit which prevents
both outputs to be ON at the same time. Even if both X1 and X2 are ON, in this case only Y1 will
be enabled.

Connect NC contact Y2 to Y1 output circuit and

one of the conditions to turn on Y2. In addition, Y1
will be OFF when Y2 is ON, which forms an
sequential control process.
Example 8 - Oscillating Circuit

In the first scan, Y1 turns on. In the second scan, Y1 turns off due to the reversed state of contact
Y1. Y1 output status changes in every scan and forms an oscillating circuit with output cycleΔ
T(ON)+ΔT(OFF)

When X0 = ON, T0 starts timing (nT). Once the set time is reached, contact T0 = ON to enable
Y1(ΔT). In next scan, Timer T0 is reset due to the reversed status of contact Y1. Therefore contact
T0 is reset and Y1 = OFF. In next scan, T0 starts timing again. The process forms an oscillating
circuit with output cycle nT+ΔT.
Example 10 - Flashing Circuit
The ladder diagram uses two timers to form an oscillating circuit which enables a flashing indicator
or a buzzing alarm. n1 and n2 refer to the set values in T1 and T2 and T refers to timer resolution.

PLC Bits, Nibbles, Bytes, Words, etc
For different control purposes, there are five types of values inside DVP-PLC for executing the
operations.
Numeric
Description
Bit
Bit is the basic unit of a binary number system. Range is 0 or 1
Nibble
Consists of 4 consecutive bits, e.g. b3~b0. Range 0 ~ 9 in Decimal or 0~F in
Hex
Consists of 2 consecutive nibbles, e.g. b7~b0. Range 00 ~ FF in Hex
Byte
Consists of 2 consecutive bytes, e.g. b15~b0. Range 0000 ~ FFFF in Hex
Word
Double Word
Consists of 2 consecutive words, e.g. b31~b1. Range 00000000 - FFFFFFFF
in Hex

Binary, Octal, Decimal, BCD, Hex
For fulllfilling different kinds of internal manipulation, DVP-PLC appies 5 foramts of number systems.
Each number system has its specific purpose and function described as below.
1.
Binary Number, (BIN)
PLC internally calculates, operates, and stores the value in Binary format.
2.
Octal Number, (OCT)
The external I/O points of DVP-PLC are numbered in octal format.
e.g.
External inputs: X0～X7, X10～X17, …, X377. (No. of device)
External outputs: Y0～Y7, Y10～Y17, …, Y377. (No. of device)
3.
Decimal Number, (DEC)
DVP-PLC appies decimal operation in situations below:
z
z
z
Set value for timers and counters, e.g. TMR C0 K50. (K value)
No. of S, M, T, C, D, E, F, P, I devices, e.g. M10, T30. (No. of device)
For use of operand in API instructions, e.g. MOV K123 D0. (K value)
2-15
D V P - E S 2 / E X 2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
z
Constant K:
Decimal value in PLC operation is attached with an “K”, e.g. K100 indicates the value 100 in
Decimal format.
Exception:
When constant K is used with bit devices X, Y, M, S, the value specifed after K indicates
the groups of 4-bit unit, which forms a digit(4-bit), byte(8 bit), word(16bit), or double
word(32-bit) data, e.g. K2Y10, K4M100, representing Y10 ~ Y17 and M100~M115.
4.
BCD (Binary Coded Decimal)
BCD format takes 1 digit or 4 bits to indicate a Decimal value, so that data of consecutive 16
bits indicates a 4-digit decimal value. Used mainly for reading values from DIP switches or
sending data to 7-segement displays
5.
Hexadecimal Number, HEX
DVP-PLC appies Hexadecimal operation in situations below:
z
For use of operand in API instructions, e.g. MOV H1A2B D0。(H value)
z
Constant H:
Hexadecimal value in PLC operation is attached with an “H”, e.g. H100 indicates the value
100 in Hex format.

M Relay
The types and functions of special auxiliary relays (special M) are listed in the table below. Care
should be taken that some devices of the same No. may bear different meanings in different series
MPUs. Special M and special D marked with “*” will be further illustrated in 2.13. Columns marked
with “R” refers to “read only”, “R/W” refers to “read and write”, “-“ refers to the status remains
unchanged and “#” refers to that system will set it up according to the status of the PLC.

Starting instruction in Sequential Function Chart (SFC).
S0~S9, total 10 points.
Returns to zero point when using IST instruction in program. Zero
return step relays not used for IST instruction can be used as
general step relays.
S10~S19, total 10 ponits.
In sequential function chart (SFC), latched step relay will be saved
when power loss after running. The state of power on after power
loss will be the same as the sate before power loss.
S20 ~ S127, total 108 points.
General relays in sequential function chart (SFC). They will be
cleared when power loss after running.
S128 ~ S911, total 784 points.
Used with alarm driving instruction API 46 ANS as an alarm
contact for recording the alarm messages or eliminating external
malfunctions.
S912 ~ S1023, total 112 points.
2.10 T (Timer)
The units of the timer are 1ms, 10ms and 100ms and the counting method is counting up. When
the present value in the timer equals the set value, the associated output coil will be ON. The set
value should be a K value in decimal and can be specified by the content of data register D.
The actual set time in the timer = timer resolution× set value
Ex: If set value is K200 and timer resolution is 10ms, the actual set time in timer will be 10ms*200 =
2000ms = 2 sec.
General Timer
The timer executes once when the program reaches END instruction. When TMR instruction is
executed, the timer coil will be ON when the current value reaches its preset value.
When X0 = ON, TMR instruction is driven. When current value achieves K100, the assocailte timer
contact T0 is ON to drive Y0. If X0 = OFFor the power is off, the current value in T0 will be cleared
as 0 and output Y0 driven by contact T0 will be OFF.

Accumulative Timer
The timer executes once when the program reaches END instruction. When TMR instruction is
executed, the timer coil will be ON when the current value reaches its preset value. For
accumulative timers, current value will not be cleared when timing is interrupted.
Timer T250 will be driven when X0 = ON. When X0 = OFFor the power is off, timer T250 will pause
and retain the current value. When X0 is ON again, T250 resumes timing from where it was paused.

Timers for Subroutines and Interrupts
Timers for subroutines and interrupts count once when END instruction is met. The associated
output coils will be ON if the set value is achieved when End instruction executes. T184~T199 are
the only timers that can be used in subroutines or interrupts. Generals timers used in subroutines
and interrupts will not work if the subroutines or interrupts are not executing.

2.12 High-speed Counters
There are two types of high speed counters provided including Software High Speed Counter
(SHSC) and Hardware High Speed Counter (HHSC). The same Input point (X) can be designated
with only one high speed counter. Double designation on the same input or the same counter will
result in syntax error when executing DCNT instruction.

C243 and C244 support count-up mode only and occupy the associate input points X1 and
X3 as reset (“R”) function. If users do not need to apply reset function, set ON the associated
special M relays (M1243 and M1244) to disable the reset function.
8.
“Dir” refers to direction control function. OFF indicates counting up; ON indicates counting
down.
9.
When X1, X3, X4 and X5 is applied for reset function and associated external interrupts are
disabled, users can define the reset function as Rising/Falling-edge triggered by special M
relays

When X1, X3, X4 and X5 is applied for reset function and external interrupts are applied, the
interrupt instructions have the priority in using the input points. In addition, PLC will move the
current data in the counters to the associated data registers below then reset the counters.

2.14 E, F Index Registers
Index registers are used as modifiers to indicate a specified device (word, double word) by defining
an offset. Devices can be modified includes byte device (KnX, KnY, KnM, KnS, T, C, D) and bit
device (X, Y, M, S). E, F registers cannot be used for modifying constant (K, H) Index registers not
used as a modifier can be used as general purpose register.
Index register [E], [F]
Index registers are 16-bit registers which can be read and written. There are 16 points indicated as
E0~E7 and F0~F7. 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. It is recommended to use instruction DMOVP K0 E to reset E
(including F) at power-on.

Nest Level Pointer N: used with instruction MC and MCR. MC is master start instruction. When
the MC instruction is executed, the instructions between MC and MCR will be executed normally.
MC-MCR master control instruction is nested level structure and max. 8 levels can be applicable,
which is numbered from N0 to N7.
Pointer P: used with application instructions CJ, CALL, and SRET.
CJ condition jump:
When X0 = ON, program will jump from address 0 to N (designated label P1) and keep on the
execution. Instructions between 0 and N will be ignored.
When X0 = OFF, program will execute from 0 and keep on executing the followings. CJ instruction
won’t be executed at this time.

Interrupt pointer I: used with application instruction API 04 EI, API 05 DI, API 03 IRET. There are
four types of interruption pointers. To insert an interruption, users need to combine EI (enable
interruption), DI (disable interruption) and IRET (interruption return) instructions
1.
External interrupt
When input signal of input terminal X0~X7 is triggered on rising-edge or falling-edge, it will
interrupt current program execution and jump to the designated interrupt subroutine pointer
I000/I001(X0), I100/I101(X1), I200/I201(X2), I300/I301(X3), I400/I401(X4), I500/I501(X5),
I600/I601(X6), I700/I701(X7). When IRET instruction is executed, program execution returns
to the address before interrupt occurs.
When X0 (C243) works with I100/I101 (X1), X0/X1 (C246, C248, C252) works with I400/I401,
the value of C243, C246, C248, C252 will be stored in (D1240, D1241)
When X2 (C244) works with I300/I301 (X3), X2/X3 (C250, C254) works with I500/I501, the
value of C244, C250, C254 will be stored in (D1242, D1243).
2.
Timer interrupt
PLC automatically interrupts the currently executed program every a fixed period of time
(2ms~99ms) and jumps to the execution of a designated interruption subroutine
3.
Counter interrupt
The high-speed counter comparison instruction API 53 DHSCS can designate 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 ,I060, I070, I080..
4.
Communication interrupt
I140:
Communication instruction RS (COM1 RS-232) can be designated to send interrupt request when
specific charcters are received. Interrupt I140 and specific characters is set to low byte of D1167.
This function can be adopted when the PLC receives data of different length during the
2-53
D V P - E S 2 / E X 2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
communication. Set up the specific end word in D1167 and write the interruption subroutine I140.
When PLC receives the end word, the program will execute I140.
I150:
Communication instruction RS (COM2 RS-485) can be designated to send interrupt request when
specific charcters are received. Interrupt I150 and specific characters is set to low byte of D1168.
This function can be adopted when the PLC receives data of different length during the
communication. Set up the specific end word in D1168 and write the interruption subroutine I150.
When PLC receives the end word, the program will execute I150..
I160:
Communication instruction RS (COM3 RS-485) can be designated to send interrupt request when
specific charcters are received. Interrupt I160 and specific characters is set to low byte of D1169
This function can be adopted when the PLC receives data of different length during the
communication. Set up the specific end word in D1169 and write the interruption subroutine I160.
When PLC receives the end word, the program will execute I160

2.
The default in the monitor timer is 200ms. If the program is long or the operation is too
complicated, MOV instruction can be used to modify SV. See the example below for SV =
300ms.
M1002

MOV
K300
D1000
Initial pulse
3.
The maximum SV in the monitor timer is 32,767ms. However, care should be taken when
adjusting SV. If SV in D1000 is too big, it cost much longer for operation errors to be detected.
Therefore, SV is suggested to be shorter than 200ms.
4.
Scan time could be prolonged due to complicated instruction operations or too many I/O
modules being connected. Check D1010 ~ D1012 to see if the scan time exceeds the SV in
D1000. Besides modifying the SV in D1000, users can also apply WDT instruction (API 07).
When program execution progresses to WDT instruction, the internal monitor timer will be
reset and therefore the scan time will not exceed the set value in the monitor timer.

a) When the power goes from “OFF” to “ON”.
b) When WPLSoft writes the program into PLC.
c) When on-line editing is being conducted on WPLSoft.
3.
Errors might result from parameter error or grammar error. The error code of the error will be
placed in D1004. The address where the fault is located is saved in D1137. If the error
belongs to loop error it may not have an address associated with it. In this case the value in
D1137 is invalid.

If set value for RTC is invalid. RTC will display the time as Second→0, Minute→0, Hour→0,
Day→1, Month→1, Week→1, Year→0.
3.
Only when power is on can RTCs of SS2 series perform the fuction of timing. Memory of RTC
is latched. RTC will resume the time when power is down. For higher accuracy of RTC,
please conduction calibratoin on RTC when power resumes.
4.
RTCs of SA2 V1.0 及 ES2/EX2/SX2 V2.0 series can still operate for one or two weeks after
the power is off (they vary with the ambient temperature). Therefore, if the machine has not
operated since one or two weeks ago, please reset RTC.
5.
Methods of modifying RTC:
a)
Apply TWR instruction to modify the built-in real time clock. Please refer to TWR
instruction for detail.
b)
Use peripheral devices or WPLSoft to set the RTC value.

Contents:
1. The falgs should be used with EI instruction and should be inserted before EI instruction
2. The default setting of interrupt I101 (X0) is rising-edge triggered. If M1280 is ON and EI
instruction is executed, PLC will reverse the trigger direction as falling-edge triggered. The
trigger pulse direction of X1 will be set as rising-edge again by resetting M1280.
3. When M0 = OFF, M1280 = OFF. X0 external interrupt will be triggered by rising-edge pulse.
4. When M0 = ON, M1280 = ON. X0 external interrupt will be triggered by falling-edge pulse.
Users do not have to change I101 to I000.

and I100/I101, PLC will move the count value to D1241 and D1240.
b) When X0 (counter input) and X4 (external Interrupt) correspondingly work together with C246,
C248, C252 and I400/I401, PLC will move the count value to D1241 and D1240
c) When X2 (counter input) and X3 (external Interrupt) correspondingly work together with C244,
and I300/I301, PLC will move the count value to D1243 and D1242.
d) When X2 (counter input) and X5 (external Interrupt) correspondingly work together with C250,
C254 and I500/I501, PLC will move the count value to D1243 and D1242.

Explanation:
a)
b)
PLC LINK is based on MODBUS communication protocol
Baud rate and communication format of all phariferal devices connected to the Slave PLC
should be the same as the communication format of Master PLC, no matter which COM port
of Slave PLC is used.
When M1356 = OFF(Default), the station number of the starting Slave (ID1) can be
designated by D1399 of Master PLC through PLC LINK, and PLC will automatically assign
ID2~ID16 with consecutive station numbers according to the station number of ID1. For
example, if D1399 = K3, Master PLC will send out communication commands to ID1~ID16
which carry station number K3~K18. In addition, care should be taken when setting the
station number of Slaves. All station numbers of slaves should not be the same as the station
number of the Master PLC, which is set up in D1121/D1255.
When both M1353 and M1356 are ON, the station number of ID1~ID16 can be specified by
the user in D1900~D1915 of Master PLC. For example, when D1900~D1903 = K3, K3, K5,
K5, Master PLC will access the Slave with station number K3 for 2 times, then the slave with
station number K5 for 2 times as well. Note that all station numbers of slaves should not be
the same as the station number of the Master PLC, and M1353 must be set ON for this
function.
Station number selection function (M1356 = ON) is supported by versions of ES2/EX2 v1.4.2
or later, SS2/SX2 v1.2 or later, and SA2 v1.0 or later.

Operation:
a)
Set up the baud rates and communication formats. Master PLC and all connected Slave
PLCs should have the same communication settings. COM1_RS-232: D1036, COM2_RS-485:
D1120, COM3_RS-485: D1109.

b)
c)
d)
e)
Set up Master PLC ID by D1121 and the starting slave ID by D1399. Then, set slave ID of
each slave PLC. The ID of master PLC and slave PLC cannot be the same.
Set data length for accessing. (If data length is not specified, PLC will take default setting or
the previous value as the set value. For details of data length registers, please refer to the
tables above)
Set starting reference of the Slave to be accessed. (Default setting for starting reference to be
read: H1064 (D100); default setting for starting reference to be written: H10C8 (D200). For
details of starting reference registers, please refer to the tables above)
Steps to start PLC LINK:
Set ON M1354 to enable simultabeous data read/write in a polling of PLC LINK..
M1355 = ON, Slave status is user-defined. Set the linking status of Slave manually by
M1360~M1375. M1355 = OFF, Slave status is auto-detected. Linking status of Slave
can be monitored by M1360~M1375
Select auto mode on PLC LINK by M1351 or manual mode by M1352 (Note that the 2
flags should not be set ON at the same time.) After this, set up the times of polling cycle
by D1431.
Finally, enable PLC LINK (M1350)
8.
The Operation of Master PLC:
a)
M1355 = ON indicates that Slave status is user-defined. Set the linking status of Slave
manually by M1360~M1375.
M1355 = OFF indicates that Slave status is auto-detected. Linking status of Slave can be
monitored by M1360~M1375.
Enable PLC LINK (M1350). Master PLC will detect the connected Slaves and store the
number of connected PLCs in D1433. The time for detection differs by number of
connected Slaves and time-out setting in D1129.
M1360~M1375 indicate the linking status of Slave ID 1~16
If no slave is detected, M1350 will be OFF and PLC LINK will be stopped.
PLC will only detect the number of slaves at the first time when M1350 turns ON.
After auto-detection is completed, master PLC starts to access each connected slave.
Once slave PLC is added after auto-detection, master PLC cannot access it unless
auto-detection is conducted again.
Simultaneous read/write function (M1354) has to be set up before enabling PLC LINK. Setting
up this flag during PLC LINK execution will not take effect.
When M1354 = ON, PLC takes Modbus Function H17 (simultaneous read/write function) for
PLC LINK communication function. If the data length to be written is set to 0, PLC will select
Modbus Function H03 (read multiple WORDs) automatically. In the same way, if data length
to be read is set to 0, PLC will select Modbus Function H06 (write single WORD) or Modbus
Function H10 (write multiple WORDs) for PLC LINK communication function.
When M1353 = OFF, PLC LINK accesses the Slave with max 16 words, and the data is
automatically stored in the corresponding registers. When M1353 = ON, up to 50 words are

accessible and the user can specify the starting register for storing the read/written data.
For example, if the register for storing the read/written data on Slave ID1 is specified as
D1480 = K500, D1496 = K800, access data length D1434 = K50, D1450 = K50, registers of
Master PLC D500~D549 will store the data read from Slave ID1, and the data stored in
D800~D849 will be written into Slave ID1.
Master PLC conducts reading before writing. Both reading and writing is executed according
to the range specified by user.
Master PLC accesses slave PLCs in order, i.e. data access moves to next slave only when
access on previous slave is completed.
9.
Auto mode and Manual mode:
a)
Auto mode (M1351): when M1351 = ON, Master PLC will access slave PLCs as the operation
described above, and stop the polling till M1350 or M1351 is OFF.
Manual mode (M1352): When manual mode is selected, times of polling cycle in D1431 has
to be set up. A full polling cycle refers to the completion of accessing all Slaves. When PLC
LINK is enabled, D1432 starts to store the times of polling. When D1431 = D1432, PLC LINK
stops and M1352 is reset. When M1352 is set ON again, PLC will start the polling according
to times set in D1431 automatically.
b)
c)
Note:
Auto mode M1351 and manual mode M1352 cannot be enabled at the same time. If
M1351 is enabled after M1352 is ON, PLC LINK will stop and M1350 will be reset.
Communication timeout setting can be modified by D1129 with available range 200 ≦
D1129 ≦ 3000. PLC will take the upper / lower bound value as the set value if the
specified value is out of the available range. D1129 has to be set up before M1350 = ON.
PLC LINK function is only valid when baud rate is higher than 1200 bps. When baud
rate is less than 9600 bps, please set communication time-out to more than 1 second.
The communication is invalid when data length to be accessed is set to 0.
Access on 32-bit high speed counters (C200~C255) is not supported.
Available range for D1399: 1 ~ 230. PLC will take the upper / lower bound value as the
set value if the specified value exceeds the availanle range.
D1399 has to be set up before enabling PLC LINK. Setting up this register during PLC
LINK execution will not take effect.
Advantage of using D1399 (Designating the ID of starting Slave):
In old version PLC LINK, PLC detects Slaves from ID1 to ID16. Therefore, when PLC
LINK is applied in multi-layer networks, e.g. 3 layers of networks, the Slave ID of 2nd and
3rd layer will be repeated. When Slave ID is repeated, i.e. the same as Master ID, the
Slave will be passed. In this case, only 15 Slaves can be connected in 3rd layer. To
solve this problem, D1399 can be applied for increasing the connectable Slaves in multilayer network structure.

The area of ‘Operands’ lists the devices (operands) required for the instruction. Identification
letters are used to associate each operand with its function, e.g. D-destination, S-source, n,
m-number of devices. Additional numeric suffixes will be attached if there are more than one
operand with the same function, e.g. S1, S2.
3.
When using WPLSoft for programming user program, it is not necessary to remember the
API number of an instruction since WPLSoft offers drop down list to select an instruction.
4.
Applicable controllers are identified by the boxes at the right of the table. For individual
instruction properties of Pulse, 16-bit or 32-bit, please refer to the box down the table.
5.
Pulse operation requires a ‘P’ to be added directly after the mnemonic while 32 bit operation
requires a ‘D’ to be added before the mnemonic, i.e. if an instruction was being used with
both pulse and 32 bit operation it appears as “D***P” where *** is the basic mnemonic.
Instruction Composition
The application instructions are specified by API numbers 0~--- and each has its mnemonic. When
designing the user program with ladder editing program (WPLSoft), users only need to key in the
mnemonic, e.g. MOV, and the instruction will be inserted. Instructions consist of either just the
instruction or the instruction followed by operands for parameter settings. Take MOV instruction for
example:
X0
MOV

3. Instruction Set
Source: if there are more than one source is required, it will be indicated as S1, S2....etc.
Destination: if there are more than one destination is required, it will be indicated as D1,
D2....etc.
If the operand can only be constant K/H or a register, it will be represented as m, m1, m2, n, n1,
n2…etc.
Length of Operand (16-bit or 32-bit instruction)
The length of operand can be divided into two groups: 16-bit and 32-bit for processing data of
different length. A prefix ”D” indicates 32-bit instructions.

Applicable PLC models for 16-bit/32-bit/pulse execution instruction.
Continuous execution vs. Pulse execution
1.
There are two execution types for instructions: continuous execution instruction and pulse
instruction. Program scan time is shorter when instructions are not executed. Therefore,
using the pulse execution instruction can reduce the scan time of the program.
2.
The ‘pulse’ function allows the associated instruction to be activated on the rising edge of the
drive contact. The instruction is driven ON for the duration of one program scan.
3.
In addition, while the control input remains ON, the associate instruction will not be executed
for the second time. To re-execute the instruction the control input must be turned from OFF
to ON again.
Pulse execution instruction
When X0 goes from OFF to ON, MOVP
instruction will be executed once and the
X0
MOVP
D10
D12
instruction will not be executed again in the scan
period
Continuous execution instruction
When X1=ON, the MOV instruction can be
re-executed again in every scan of program. This
X1
MOV
D10
D12
is called continuous execution instruction.
Operands
1.
Bit devices X, Y, M, and S can be combined into word device, storing values and data for
operations 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 D consists of 16 bits, i.e. a 32-bit data register consists of 2 consecutive D
registers.
4.
If an operand of a 32-bit instruction designates D0, 2 consecutive registers D1 and D0 will be
occupied. D1 is thehigh word and D0 is the low word. This proncipal also applys to timer T
and 16-bit counters 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.
Operand Data format
3-16
3. Instruction Set
1. X, Y, M, and S are defined as bit devices which indicate ON/OFF status.
2. 16-bit (or 32-bit) devices T, C, D, and registers E, F are defined as word devices.
3. “Kn” can be placed before bit devices X, Y, M and S to make it a word device for performing
word-device operations. (n = 1 refers to 4 bits. For 16-bit instruction, n = K1 ~ K4; for 32-bit
instruction, n = K1 ~ K8). For example, K2M0 refers to 8 bits, M0 ~ M7.
When X0 = ON, the contents in M0 ~ M7 will be
X0

K2M0
moved to b0 ~b7 in D10 and b8 ~b15 will be

Flags
1.
General Flags
The flags listed below are used for indicating the operation result of the application
instruction:
M1020: Zero flag
M1021: Borrow flag
M1022: Carry flag
M1029: Execution of instruction is completed
All flags will turn ON or OFF according to the operation result of an instruction. For example,
the execution result of 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.

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.
3.
Flags to Extend Functions
Some instructions can extend their function by using some special flags.
Example: instruction RS can switch transmission mode 8-bit and 16-bit by using M1161.
Device
Explanation
M1067
When operational errors occur, M1067 = ON. D1067 displays the error code.
D1067
D1069 displays the address where the error occurs. Other errors occurring will
D1069
update the contents in D1067 and D1069. M1067 will be OFF when the error is
cleared.
When operational errors occur, M1068 = ON. D1068 displays the address
M1068
D1068
where the error occurs. Other errors occurring wil not update the content in
D1068. RST instruction is required to reset M1068 otherwise M1068 is latched.
Limitations for times of using instructions
Some instructions can only be used a certain number of times in a program. These instructions
can be modified by index registers to extend their functionality.
1.
Instructions can be used once in a program:
API 60 (IST)
2.
API 155 (DABSR)
Instruction can be used twice in a program:
API 77 (PR)
3.
Instruction can be used 8 times in a program:
API 64 (TTMR)
4.
For counters C232~C242, the total max times for using DHSCS, DHSCR and DHSZ
instructions: 6. DHSZ can only be used less than 6 times.
3-18
3. Instruction Set
5.
For counters C243, C245~C248, C251, C252, the total max times for using DHSCS, DHSCR
and DHSZ instructions: 4. DHSZ takes up 2 times of the total available times.
6.
For counters C244, C249, C250, C253, C254, the total max times for using DHSCS, DHSCR
and DHSZ instructions: 4. DHSZ takes up 2 times of the total available times.
Limitation of synchronized execution
Most instructions have no limitation on the times to be used in a program, but there are limitations
on the number of instruction to be executed in the same scan cycle.
1. Only 1 instruction can be executed at the same scan cycle: API 52 MTR, API 69 SORT, API
70 TKY, API 71 HKY, API 72 DSW, API 74 SEGL, API 75 ARWS.
2. Only 4 instruction can be executed at the same scan cycle: API 56 SPD, API 169 HOUR.
3. There is no limitation on the times of using the high-speed output instructions API 57 PLSY,
API 58 PWM, API 59 PLSR, API 156DZRN, API 158 DDRVI, API 159 DDRVA and API 195
DPTPO, but only one high-speed output instruction will be executed in the same scan time.
4. There is no limitation on the times of using the communication instructions API 80 RS, API
100 MODRD, API 101 MODWR, API 102 FWD, API 103 REV, API 104 STOP, API 105 RDST,
API 106 RSTEF , API 150 MODRW, but only one communication instruction will be executed
on single COM port during the same scan cycle.
Numeric Values
1.
Devices indicates ON/OFF status are called bit devices, e.g. X, Y, M and S. Devices used for
storing values are called word devices, e.g. T, C, D, E and F. Although bit device can only be
ON/OFF for a single point, they can also be used as numeric values in the operands of
instructions if the data type declaration device Kn is added in front of the bit device.
2.
For 16-bit data, K1~K4 are applicable. For 32-bit data, K1~K8 are applicable. For example,
K2M0 refers to a 8-bit value composed of M0 ~ M7.

3.
Transmit K1M0, K2M0, K3M0 to 16-bit registers. Only the valid bit data will be transmitted
and the upper bits in the 16-bit register will all be filled with 0. The same rule applies when
sending K1M0, K2M0, K3M0, K4M0, K5M0, K6M0, K7M0 to 32-bit registers.
4.
When the Kn value is specified as K1~K3 (K4~K7) for a 16-bit (32-bit) operation, the empty
upper bits of the target register will be filled with “0.” Therefore, the operation result in this
case is positive since the MSB(Most significant bit) is 0.
M0
The BCD value combined by X0 to X7 will be
K2X0
BIN
D0
converted to D0 as BIN value.
Assign Continuous Bit Numbers
As already explained, bit devices can be grouped into 4 bit units. The “n” in Kn defines the number
of groups of 4 bits to be combined for data operation. For data register D, consecutive D refers to
D0, D1, D2, D3, D4…; For bit devices with Kn, consecutive No. refers to:
K1X0
K1X4
K1X10
K1X14…
K2Y0
K2Y10
K2Y20
Y2X30…
K3M0
K3M12
K3M24
K3M36…
K4S0
K4S16
K4S32
K4S48…
Note: To avoid errors, please do not skip over the continuous numbers. In additoin, when K4Y0 is
used in 32-bit operation, the upper 16-bit is defined as 0. Therefore, it is recommended to use
K8Y0 in 32bit operation.
Floating Point Operation
The operations in DVP-PLC are conducted in BIN integers. When the integer performs division,
e.g. 40 ÷ 3 = 13, the remainder will be 1. When the integer performs square root operations, the
decimal point will be left out. To obtain the operation result with decimal point, please use floating
point instructions.

Binary Floating Point
DVP-PLC represents floating point value in 32 bits, following the IEEE754 standard:
S
8-bit
23-bit
exponent
mantissa
b31
b0
Sign bit
0: positive
1: negative
Equation (− 1) × 2 E − B × 1.M ; B = 127
S
Therefore, the range of 32-bit floating point value is from ±2-126 to ±2+128, i.e. from ±1.1755×10-38 to
±3.4028×10+38.
Example 1: Represent “23” in 32-bit floating point value
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: Represent “-23.0” in 32-bit floating point value
The steps required are the same as those in Example 1 and only differs in modifying the sign bit
into “1”.
1 10000011 011100000000000000000002=C1B8000016
DVP-PLC uses registers of 2 continuous No. to store a 32-bit floating point value. For example,
we use registers (D1, D0) for storing a binary floating point value as below:
D1(b15~b0)

Decimal Floating Point
Since the binary floating point value is not very user-friendly, we can convert it into a decimal
floating point value for use. However, please note that the floating point operation in DVP-PLC is
still operated in binary floating point format.
3-21
D V P - E S 2 / S A2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
The decimal floating point is represented by 2 continuous registers. The register of smaller
number is for the constant while the register of bigger number is for the exponent.
Example: Store 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 because 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: Convert binary floating point to decimal floating point
D EBIN: Convert decimal floating point to binary floating point
Zero flag (M1020), borrow flag (M1021), carry flag (M1022) and the floating point operation
instruction
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.
Index register E, F
The index registers are 16-bit registers. There are 16 devices including E0 ~ E7 and F0 ~ F7.
E and F index registers are 16-bit data registers
which can be read and written.
If you need a 32-bit register, you have to designate
16-bit
16-bit
F0
E0
32-bit
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
F0
E0
High byte
Low byte
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)
3-22
3. Instruction Set
The opposite diagram E, F index register modification
MOV K20E0 D10F0
refers to the content in the operand changes with the
contents in E and F.
E0 = 8
F0 = 14
For example, E0 = 8 and K20E0 represents constant
20 + 8 = 28 10 + 14 = 24
Transmission
K28
D24
K28 (20 + 8). When the condition is true, constant K28
will be transmitted to register D24.
Devices modifiable: P, X, Y, M, S, KnX, KnY, KnM, KnS, T, C, D.
E and F can modify the devices listed above but cannot modify themselves and Kn., e.g. 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.
If you need to modify device P, I, X, Y, M, S, KnX, KnY, KnM, KnS, T, C and D by applying E, F, you
have to select a 16-bit register, i.e. you can designate E or F.

Operands:
S: The destination pointer P of the conditional jump.
Explanations:
1.
If users need to skip 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.
2.
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.
3.
CJ instruction can designate the same pointer P repeatedly. However, CJ and CALL cannot
designate the same pointer P; otherwise operation error will occur
4.
Actions of all devices while conditional jump is being executed:
a) Y, M and S remain their previous status before the conditional jump takes place.
b) 10ms and 100ms timer 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) General counters stop executing.
f)
If timer is reset before CJ instruction executes, the timer will still be in the reset status while
CJ instruction is being executed.
g) The application instructions that are being executed, i.e. DHSCS, DHSCR, DHSZ, SPD,
PLSY, PWM, PLSR, PLSV, DRVI, DRVA, continue being executed.

3. Instruction Set
Program example 1:
When X0 = ON, the program will skip from address 0 to N (Pointer P1) automatically and keep on
executing. Instructions between address 0 and N will be skipped..
When X0 = OFF, program flow will proceed with the row immediately after the CJ instruction.

Program example 2:
1.
The instruction CJ between the instruction MC and the instruction MCR can be used in the five
conditions below.
a). The execution of the program jumps from the part of the program outside one MC/MCR
loop to the part of the program outside another MC/MCR loop.
b). The execution of the program jumps from the part of the program outside the MC/MCR loop
to the part of the program inside the MC/MCR loop.
c). The execution of the program jumps from the part of the program inside the MC/MCR loop
to the part of the program inside the MC/MCR loop.
d). The execution of the program jumps from the part of the program inside the MC/MCR loop
to the part of the program outside the MC/MCR loop.
e). The execution of the program jumps from the part of the program inside one the MC/MCR
loop to the part of the program inside another the MC/MCR loop.

When the instruction MC is executed, the previous state of the switch contact is put onto the
top of the stack inside the PLC. The stack is controlled by the PLC, and can not be changed by
3-43
D V P - E S 2 / S A2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
users. When the instruction MCR is executed, the previous state of the switch contact is
popped from the top of the stack. Under the conditions listed in (b), (d), and (e) above, the
number of times the items are pushed onto the stack may be different from the number of
times the items are popped from the stack. When this situation occurs, at most 32 items can
be pushed onto the stack, and the items can be popped form the stack until the stack is empty.
Therefore, when CJ or CJP is used with MC and MCR, users have to be careful of the pushing
of the item onto the stack and the popping of the item from the stack.

3. Instruction Set
*1: Y1 is dual output. When M0 is OFF, it is controlled by M1. When M0 is ON, M12 will control Y1
*2: When timer that subroutine used (T184~T199) executes first and then CJ instruction is
executed, the timer will keep counting. After the timer reaches the set value, output contact of
timer will be ON.
*3: When high-speed counters (C235~C254) executes first and then CJ instruction is executed,
the counter will keep counting and its associated output status remains.
Y1 is a dual output. When M0 = OFF, Y1 is controlled by M1. M0 = ON, Y1 is controlled by M12.

Operands:
S: The destination pointer P of the call subroutine.
Explanations:
1.
When the CALL instruction is active it forces the program to run the subroutine associated
with the called pointer.
2.
A CALL instruction must be used in conjunction with FEND (API 06) and SRET (API 02)
instructions.
3.
The program jumps to the subroutine pointer (located after an FEND instruction) and
processes the contents until an SRET instruction is encountered. This forces the program
flow back to the line of ladder immediately following the original CALL instruction.
Points to note:
1.
Subroutines must be placed after FEND instruction.
2.
Subroutines must end with SRET instruction.
3.
CALL pointers and CJ instruction pointers are not allowed to coincide.
4.
CALL instructions can call the same CALL subroutine any number of times.
5.
Subroutines can be nested 5 levels including the initial CALL instruction. (If entering the six
levels, the subroutine won’t be executed.)

Explanations:
SRET indicates the end of subroutine program. The subroutine will return to main program and
begin execution with the instruction after the CALL instruction.
Program example 1:
When X0 = ON, the CALL instruction will jump to P2 and run the subroutine. With the execution of
the SRET instruction, it will jump back to address 24 and continue the execution.

Program example 2:
1.
When the rising-edge of X20 is triggered, CALL P10 instruction will transfer execution to
subroutine P10.
2.
When X21 is ON, execute CALL P11, jump to and run subroutine P11.
3.
When X22 is ON, execute CALL P12, jump to and run subroutine P12.
4.
When X23 is ON, execute CALL P13, jump to and run subroutine P13.
5.
When X24 is ON, execute CALL P14, jump to and run subroutine P14. When the SRET
instruction is reached, jump back to the last P subroutine to finish the remaining instructions.
6.
The execution of subroutines will go backwards to the subroutine of upper level until SRET
instruction in P10 subroutine is executed. After this program execution will return to the main
program.

Explanations:
1.
EI instruction allows interrupting subroutine in the program, e.g. external interruption, timer
interruption, and high-speed counter interruption.
2.
In the program, interruption subroutines are enabled between EI and DI instructions. If there
is no section requires to be interrupt-disabled, DI instruction can be omitted.
3-49
D V P - E S 2 / S A2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
3.
Interrupt subroutines must be placed after the FEND instruction.
4.
Other interrupts are not allowed during execution of a current interrupt routine.
5.
When many interruptions occur, the priority is given to the firstly executed interruption. If
several interruptions occur at the same time, the priority is given to the interruption with the
smaller pointer No.
6.
Any interrupt request occurring between DI and EI instructions will not be executed
immediately. The interrupt will be memorized and executed when the next EI occurs.
7.
When using the interruption pointer, DO NOT repeatedly use the high-speed counter driven
by the same X input contact.
8.
When immediate I/O is required during the interruption, write REF instruction in the program
to update the status of I/O
Points to note:
Interrupt pointers (I):
a) External interrupts: 8 points including (I000/I001, X0), (I100/I101, X1), (I200/I201, X2),
(I300/I301, X3), (I400/I401, X4), (I500/I501, X5), (I600/I601, X6) and (I700/I701, X7) (00
designates interruption in falling-edge, 01 designates interruption in rising-edge)
b) Timer interrupts: 2 points including I605~I699 and I705~I799 (Timer resolution = 1ms)
c) High-speed counter interrupts: 8 points including I010, I020, I030, I040, I050, I060, I070, and
I080. (used with API 53 DHSCS instruction to generate interrupt signals)
d) Communication interrupts: 3 points including I140, I150 and I160

Note: Default setting of I000(X0) is falling-edge triggered. When M1280=ON and EI is enabled,
PLC will reverse X0 as rising-edge triggered. To reset X0 as falling-edge, reset M1280 first and

Program example:
During the PLC operation, the program scans the instructions between EI and DI, if X1 or X2 are
ON, the subroutine A or B will be interruptted. When IRET is reached, the main program will

Explanations:
1.
Use FEND instruction when the program uses either CALL instructions or interrupts. If no
CALL instruction or interrupts are used, use END instruction to end the main program.
2.
The instruction functions same as END instruction in PLC operation process.
3.
CALL subroutines must be placed after the FEND instruction. Each CALL subroutine must
end with the SRET instruction.
4.
Interrupt subroutines must be placed after the FEND instruction. Each interrupt subroutine
must end with the IRET instruction.
5.
When using the FEND instruction, an END instruction is still required, but should be placed
as the last instruction after the main program and all subroutines.
6.
If several FEND instructions are in use, place the subroutine and interruption service
programs between the final FEND and END instruction.
7.
When CALL instruction is executed, executing FEND before SRET will result in errors.
8.
When FOR instruction is executed, executing FEND before NEXT will result in errors.

Explanations:
1.
WDT instruction can be used to reset the Watch Dog Timer. If the PLC scan time (from
address 0 to END or FEND instruction) is more than 200ms, the ERROR LED will flash. In
this case, users have to turn the power OFF and then ON to clear the fault. PLC will
determine the status of RUN/STOP according to RUN/STOP switch. If there is no
RUN/STOP switch, PLC will return to STOP status automatically.
2.
Time to use WDT:
a) When an error occurs in the PLC system.
b) When the scan time of the program exceeds the WDT value in D1000. It can be modified by
using the following two methods.
i.
Use WDT instruction
STEP0
WDT
T1
ii.
END(FEND)
T2
Use the set value in D1000 (Default: 200ms) to change the time for watchdog.
Points to note:
1.
When the WDT instruction is used it will operate on every program scan as long as its input
condition has been made. To force the WDT instruction to operate for only ONE scan,
users have to use the pulse (P) format of the WDT instruction, i.e. WDTP.
2.
The watchdog timer has a default setting of 200ms. This time limit can be customized to
users requirement by editing the content in D1000, the wathdog timer register.

Program example:
If the program scan time is over 300ms, users can divide the program into 2 parts. Insert the WDT
instruction in between, making scan time of the first half and second half of the program being less
than 200ms.
300ms program
END
Dividing the program to two parts
so that both parts scan time are
less than 200ms.

Explanations:
1.
FOR and NEXT instructions are used when loops are needed. No contact to drive the
instruction is required.
2.
“N” (number of times loop is repeated) may be within the range of K1 to K32767. If the range
N≦K1, N is regarded as K1.
3.
4.
An error will occur in the following conditions:
•
NEXT instruction is before FOR instruction.
•
FOR instruction exists but NEXT instruction does not exist..
•
There is a NEXT instruction after the FEND or END instruction.
•
Number of FOR instructions differs from that of NEXT instructinos.
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.

Operands:
S1: Comparison Value 1
S2: Comparison Value 2
D: Comparison result
Explanations:
1.
The contents of S1 and S2 are compared and D stores the comparison result.
2.
The comparison values are signed binary values. If b15=1 in 16-bit instruction or b31=1 in
32-bit instruction, the comparison will regard the value as a negative binary value.
3.
Operand D occupies 3 continuous devices. D, D +1, D +2 hold the comparison results,
D = ON if S1 > S2,
4.
D +1 = ON if S1 = S2,
D +2 = ON if S1 < S2
If operand S1, S2 use index register F, only 16-bit instruction is available.
Program example:
1.
If D is set as Y0, then Y0, Y1, Y2 will display the comparison results as shown below.
2.
When X20 = ON, CMP instruction is executed and one of Y0, Y1, Y2 will be ON. When X20 =
OFF, CMP instruction is not executed and Y0, Y1, Y2 remain in their previous condition.
X20
CMP

D10

If K10>D10, Y0 = On
Y1
If K10=D10, Y1 = On

If K10 S2, the instruction takes S1 as the
1st comparison value and performs normal comparison similar to CMP instruction.
4.
If operand S1, S2 , and S use index register F, only 16-bit instruction is available.
5.
Operand D occupies 3 continuous devices. D, D +1, D +2 hold the comparison results,
D = ON if S1 > S,
D +1 = ON if S1 ≦ S ≦ S2,
D +2 = ON if S2 < S
Program example:
1.
If D is set as M0, then M0, M1, M2 will work as the program example below.
2.
When X0 = ON, ZCP instruction is driven and one of M0, M1, M2 is ON. When X0 = OFF,
ZCP instruction is not driven and M0, M1, M2 remain in the previous status.

Operands:
S: Source of data
D: Destination of data
Explanations:
1.
When this instruction is executed, the content of S will be moved directly to D. When this
instruction is not executed, the content of D remains unchanged
2.
If operand S and D use index register F, only 16-bit instruction is applicable
Program example:
1.
MOV will move a 16-bit value from the source location to the destination.
a) When X0 = OFF, the content of D0 remains unchanged. If X0 = ON, the data in K10 is
moved to D0.
b) When X1 = OFF, the content of D10 remains unchanged. If X1 = ON, the data of T0 is
moved to D10 data register.
2.
DMOV will move a 32-bit value from the source location to the destination.
a) When X2 = OFF, the content of (D31, D30) and (D41, D40) remain unchanged.
b) When X2 = ON, the data of (D21, D20) is moved to (D31, D30) data register. Meanwhile, the
data of C235 is moved to (D41, D40) data register.

m1: Start digit to be moved from source device m2: Number of digits to be
D: Destination device
n: Start digit of the destination device for the moved digits
Explanation:
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.
M1168 is used for designating SMOV working mode. When M1168 = ON, the instruction is in
BIN mode. When M1168 = OFF, the instruction is in BCD mode.
Points to note:
1.
The range of m1: 1 – 4
2.
The range of m2: 1 – m1
3.
The range of n: m2 – 4
3-64
3. Instruction Set
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 detects an operation error and will
not execute the instruction. M1067, M1068 = ON and D1067 stores the error code OE18
(hex).

Explanations:
1.
The contents in the devices designated by D1 and D2 will exchange
2.
It is better to apply a pulse execution for this instruction (XCHP).
3.
If operand D1 and D2 use index register F, only 16-bit instruction is available.

2.
As a 32-bit instruction, when the devices designated by D1 and D2 are the same and M1303
= ON, the upper and lower 16 bits in the designated device exchange with each other.
3.
When X0 = ON and M1303 = ON, 16-bit contents in D100 and those in D101 will exchange
with each other.

Operands:
S: Source of data

Explanations:
1.
The content in S (BIN value) is converted into BCD value and stored in D
2.
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)
3.
If operand S and D use index register F, only 16-bit instruction is available.
4.
Flags: M1067 (Program execution error), M1068 (Execution error locked), D1067 (error
code)
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).

2.
The valid range of source S: BCD (0 to 9,999), DBCD (0 to 99,999,999)
3.
If the content of S is not a valid BCD value, an operation error will occur, error flags M1067
and M1068 = ON, and D1067 holds error code H0E18.
4.
If operand S and D use index register F, only 16-bit instruction is available.
5.
Flags: M1067 (Program execution error), M1068 (Execution error locked), D1067 (error

Points to note:
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.
On the contrary when PLC needs to display a value on a BCD format 7-segment displayer,
BCD instruction is required to convert the internal data into BCD value then sent the value to
the displayer.
3.
When X0 = ON, the BCD value of K4X20 is converted into BIN value and sent to D100. The
BIN value of D100 will then be converted into BCD value and sent to K4Y20.

D: Device to store the operation result of 2’s Compliment
Explanations:
1. This instruction conducts operation of 2’s complement and can be used for converting a
negative BIN value into an absolute value.
2. This instruction is generally used in pulse execution mode (NEGP, DNEGP).
3. If operand D uses index F, only a 16-bit instruction is available.
Program Example 1:
When X0 goes from OFF to ON, the phase of each bit in D10 will be reversed (0→1, 1→0) and
then 1 will be added to the Least Significant Bit (LSB) of the register. Operation result will then be
stored in D10.
X0
NEGP
D10
Program Example 2:
To obtain the absolute value of a negative value:
1.
When MSB (b15) of D0 is “1”, M0 = ON. (D0 is a negative value).
2.
When M0 = ON, the absolute value of D0 can be obtained by NEG instruction.

Program Example 3:
Obtain the absolute value of the remainder of the subtraction. When X0 = ON,
a) If D0 > D2, M0 = ON.
b) If D0 = D2, M1 = ON.
c) If D0 < D2, M2 = ON.
d) D4 is then able to remain positive.

Operands:
S: Source device
D: Head address of data stack
n: Length of data stack
Explanations:
1.
This instruction defines the data stack of n words starting from D as a “first-in, first out
(FIFO)” data stack and specifies the first device as the pointer (D). When SFWRP is
executed, content in pointer pluses 1, and the content in S will be written into the device
designated by the pointer. When the content in pointer exceeds n-1, the instruction stops and
carry flag M1022= ON.
2.
This instruction is generally used in pulse execution mode (SFWRP).
3.
Valid range of operand n: 2≤ n ≤512
Program Example:
1.
First, reset the content of D0. When X0 goes from OFF to ON, the content of D0 (pointer)
becomes 1, and D20 is written into D1. If the content of D20 is changed and X0 is triggered
again, pointer D0 becomes 2, and the content of D20 is then written into D2.
2.

n: Length of data stack
Explanation:
1.
This instruction defines the data stack of n words starting from S as a FIFO data stack and
specifies the first device as the pointer (S). The content of pointer indicates current length of
the stack. When SFRDP is executed, first data (S+1) will be read out to D, all data in this
stack moves up to fill the read device and content in pointer minuses 1. When the content in
pointer = 0, the instruction stops and carry flag M1022= ON
2.
This instruction is generally used in pulse execution mode (SFRDP).
3.
Valid range of operand n: 2≤ n ≤512
Program Example:
1.
When X0 goes from OFF to ON, D9~D2 are all shifted to the right and the pointer D0 is
decremented by 1 when the content of D1 is read and moved to D21.
2.
The figure below illustrates the shift and reading of the instruction.

n: Number of consecutive device from S
Explanations:
1.
The instruction obtains the mean value from n consecutive registers from S and stores the
value in D.
2.
Remainders in the operation will be ignored.
3.
If S is not within the valid range, only those addresses within the valid range will be
processed.
4.
If n is out of the valid range (1~64), PLC will determine it as an “instruction operation error”.
5.
If operand D uses index F, only a 16-bit instruction is available.
6.
Valid range of operand n : n = 1~64
Program Example:
When X10 = ON, the contents in 3 (n = 3) registers starting from D0 will be summed and then
divided by 3 to obtain the mean value. The result will be stored in D10 and the remainder will be

Explanations:
1.
ANR instruction is used to reset an alarm.
2.
When several alarm devices are ON, the alarm with smaller number will be reset.
3.
This instruction is generally used in pulse execution mode (ANRP).
Program Example:
1.
If X20 and X21 are ON at the same time for more than 2 sec, the alarm S912 will be ON. If
X20 or X21 is reset, alarm S912 will remain ON but T10 will be reset and present value is
cleared.
2.
If X20 and X21 are ON less than 2 sec, the present value of T10 will be cleared.
3.
When X3 goes from OFF → ON, activated alarms S912 will be reset.
4.
When X3 goes from OFF → ON again, the alarm device with second lower number will be
reset.

Points to note:
Flags:
1.
M1048 (indicating alarm status): When M1049 = ON, enabling any of the alarm S912~S1023
turns M1048 ON.
2.
M1049 (Enabling alarm monitoring): When M1049 = ON, D1049 will automatically hold the
lowest alarm number in active alarms.
Application example of alarm device (production line):
X0 = Forward switch
X1 = Backward switch
X2 = Front position switch
X3 = Back position switch
X4 = Alarm reset button
Y0 = Forward
Y1 = Backward
Y2 = Alarm indicator
S912 = Forward alarm

When Y0 = ON for more than 10 sec and the product fails to reach the front position X2,
S912 = ON
3.
When Y1 = ON for more than 10 sec and the product fails to reach the back position X3,
S920= ON.
4.
When backward switch X1 = ON and backward device Y1 = ON, Y1 will go OFF only when
the product reaches the back position switch X3.
5.
Y2 is ON when any alarm is enabled.
6.
Whenever X4 is ON, 1 active alarm will be reset. If there are several active alarms, the reset
will start from the alarm with the lowest number and then the alarm with second lower
number, etc.

Explanation:
1.
This instruction performs a square root operation on S and stores the result in D.
2.
S can only be a positive value. Performing a square root operation on a negative value will
result in an error and the instruction will not be executed. The error flag M1067 and M1068 =
ON and D1067 records error code H0E1B.
3.
The operation result D should be integer only, and the decimal will be left out. When decimal
is left out, borrow flag M1021 = ON.
4.
When the operation result D = 0, zero flag M1020 = ON.
Program Example:
When X20 = ON, square root of D0 will be stored in D12.

Operands:
S: Source device
D: Device for storing the conversion result
Explanations:
1.
When M1081 = OFF, the source S is converted from BIN integer to binary floating point value.
At this time, 16-bit instruction FLT occupies 1 register for S and 2 registers for D.
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 conversion result is 0, zero flag M1020 = ON.
2.
When M1081 is ON, the source S is converted from binary floating point value to BIN integer.
(Decimal ignored). At this time, 16-bit instruction FLT occupies 2 registers for S and 1
register for D. The operation is same as instruction INT.
a) If the conversion result exceeds the available range of BIN integer 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 the decimal is ignored, borrow flag M1021=ON.
c) If the conversion result = 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 X20 = ON, D0 is converted to D13, D12 (floating point).
3.
When X21 = ON, D1, D0 are converted to D21, D20 (floating point).
4.
Assume D0 is K10. When X10 is ON, the converted 32-bit value will be H41200000 and
stored in 32-bit register D12 (D13)
5.
If 32-bit register D0 (D1)=K100,000, X21 = ON. 32-bit of floating point after conversion will be
H47C35000 and it will be saved in 32-bit register D20 (D21)

When M1081 = ON, the source data is converted from floating point value to BIN integer.

2.
When X20 = ON, D1 and D0 (floating point) are converted to D12 (BIN integer). If D0 (D1) =
H47C35000, the result will be 100,000 which exceeds the available range of BIN integer in
16-bit register D12. In this case the result will be D12 = K32767, and M1022 = ON
3.
When X21 = ON, D1 and D0 (floating point) are converted to D21, D20 (BIN integer). If D0
(D1) = H47C35000, the result is 100,000 and will be saved in 32-bit register D20 (D21).

Operands:
D: Start device for I/O refresh
n: Number of devices for I/O refresh
Explanations:
1.
PLC updates I/O status between END instruction and the start of next program scan. If an
immediate I/O refresh is needed, REF can be applied for performing I/O refresh immediately.
2.
D can only be a multiple of 10, i.e. X0 or Y0, and the instruction is NOT applicable for I/O
points on DIO modules.
3.
Only the I/O points on MPU can be specified for operand D for I/O refresh.
z
When D specifies X0 and n ≦ 8, only X0~X7 will be refreshed. If n > 8, all I/O points on
MPU will be refreshed.
z
When D specifies Y0 and n = 8, only Y0~X7 will be refreshed. If n > 8, all I/O points on
MPU will be refreshed.
z
When D specifies X10 or Y10, I/O points on MPU except for X0~X7 or Y0~Y3 will all be
refreshed regardless of n value, i.e. only status of X0~X7 or Y0~Y3 remains.
4.
For EX2/SX2 MPU only: If M1180 = ON and REF instruction executes, PLC will read the A/D
value and update the read value to D1110~D1113. If M1181 = ON and REF instruction
executes, PLC will output the D/A value in D1116 and D1117 immediately. When A/D or D/A
values are refreshed, PLC will reset M1180 or M1181 automatically.
5.
Range for n (ES2/EX2): 4 ~ total I/O points on MPU. n should always be a multiple of 4.
6.
Range for n (SS2/SA2/SE/SX2): 8 ~ total I/O points on MPU.

When X0 = ON, PLC will refresh the status of input points X0 ~ X7 immediately without delay.

n: Response time (unit: ms)
Explanation:
1.
PLC provides digital input filters to avoid interference. The response time (n) of X0 ~ X7 input
filters can be adjusted by REFF instruction. The instruction sets the value specified in n to
D1020 (X0 ~ X7 input filter time) directly.
2.
When PLC turns from OFF to ON or the END instruction is reached, the response time is
dictated by the value of D1020.
3.
During program execution, the value in D1020 can be changed by using MOV instruction.
4.
When using REFF instruction during program execution, the modified response time will be
move to D1020 and refreshed until next program scan..
5.
Range of n: = K2 ~ K20.
Program Example:
1.
When the power of PLC turns from OFF to ON, the response time of X0~X7 inputs is
specified by the value in D1020.
2.
When X20 = ON, REFF K5 instruction is executed, response time changes to 5 ms and takes
affect the next scan.
3.
When X20 = OFF, the REFF instruction will not be executed, the response time changes to
20ms and takes affect the next scan.

Operands:
S: Head address of input device
matrix scan
D1: Head address of output device
D2: Head address of
n: Number of arrays in the matrix
Explanations:
1.
S is the source device of the matrix input and occupies 8 consecutive points.
D1 is the trigger device (transistor output Y) to read input signals and occupies n consecutive
points
D2 is the head address of the matrix which stores the read status from inputs
2.
This instruction allows 8 continuous input devices starting from S to be used n times, which
means the operation result can be displayed with a matrix table starting from D2 . Each set of
8 input signals are grouped into an “array” and there are n number of arrays. Each array is
selected to be read by triggering output devices starting from D1. The result is stored in a
matrix-table which starts at corresponding head address D2.
3.
Maximum 8 arrays can be specified (n = 8) to obtain 64 input points (8 × 8 = 64).
4.
The processing time of each array is approximately 25ms, i.e. an 8 array matrix would cost
200ms to finish reading. In this case, input signals with ON/OFF speed faster than 200ms are
not applicable in the matrix input.
5.
It is recommended to use special auxiliary relay M1000 (normally open contact).
6.
Whenever this instruction finishes a matrix scan, M1029 will be ON for one scan period..
7.
There is no limitation on the number of times for using the instruction, but only one instruction
can be executed in the same time.
8.
Flag: M1029, execution completed flag.
Program Example:
When PLC runs, MTR instruction executes. The status of input points X40~X47 is read 2 times in
the driven order of output points Y40 and Y41, i.e. 16 signals will be generated and stored in
internal relay M10~M17 and M20~M27.

Operands:
S1: Comparative value
S2: No. of high-speed counter
D: Compare result
Explanations:
1.
Functions related to high-speed counters adopt an interrupt process; therefore, devices
specified in D which indicates comparison results are updated immediately. This instruction
compares the present value of the designated high-speed counter S2 against a specified
comparative value S1. When the current value in counters equals S1, device in D will be ON
even when values in S1 and S2 are no longer equal.
2.
If D is specified as Y0~Y3, when the instruction is executed and the count value equals to S1 ,
the compare result will immediately output to the external outputs Y0~Y3. However, other Y
outputs will still be updated till the end of program. Also, M and S devices, not affected by the
program scan time, will be immediate updated as the Y devices specified by this instruction.
3.
Operand D can designate I0□0, □=1~8
4.
High speed counters include software high speed counters and hardware high speed
counters. In addtiion, there are also two types of comparators including software
comparators and hardware comparators. For detailed explanations of high speed counters
please refer to section 2.9 in this manual.
5.
Explanations on software comparators for DHSCS/DHSCR instruction:
¾
There are 6 software comparators for the high-speed compare Set/Reset.
¾
There are 6 software comparators available corresponding to associated high speed
counter interrupts. Numbers of the applied interrupts should also be specified correctly
in front of the associated interrupt subroutines in the program.
¾
When programming DHSCS and DHSCR instructions, the total of Set/Reset
comparisons for both instructions can not be more than 6, otherwise syntax check error
will occur.

Explanations on hardware comparators DHSCS/DHSCR instruction:
¾
There are 2 groups of hardware comparators provided respectively for 2 groups of
hardware counters (A group and B group), and each group shares 4 comparators with
individual Compare Set/Reset function.
¾
When programming DHSCS and DHSCR instructions, the total of Set/Reset
comparisons for both instructions can not be more than 4, otherwise syntax check error
will occur.
¾
Each high-speed counter interrupt occupies an associated hardware comparator,
consequently the interrupt number can not be repeated. Also, I010~I040 can only be
applied for group A comparators and I050~I080 for group B.

Count value storage function of high speed interrupt:
¾
When X1, X3, X4 and X5 is applied for reset function and associated external interrupts
are disabled, users can define the reset function as Rising/Falling-edge triggered by
special M relays specified in the table: Applicable Software High Speed Counters.
However, if external interrupts are applied, the interrupt instructions have the priority in
using the input points. In addition, PLC will move the current data in the counters to the
associated data registers below then reset the counters
¾
When X0 (counter input) and X1 (external Interrupt I100/I101) work with C243, the
count value will be moved to D1240 and D1241 when interrupt occurs and then the
counter will be reset.
¾
When X2 (counter input) and X3 (external Interrupt I300/I301) work with C244, the
count value will be moved to D1242 and D1243 when interrupt occurs and then the
counter will be reset.
¾
When X0 (counter input) and X4 (external Interrupt I400/I401) work with C246, C248,
C252, the count value will be moved to D1240 and D1241 when interrupt occurs and
then the counter will be reset.
¾
When X2 (counter input) and X5 (external Interrupt I500/I501) work with C244, C250,

1.
DHSCR compares the current value of the counter S2 against a compare value S1. When the
counters current value changes to a value equal to S1, then device D is reset to OFF. Once
reset, even if the compare result is no longer unequal, D will still be OFF.

For SS2/SA2/SX2/SE and ES2/EX2 V1.00 or later: when X0, X2, X4 and X6 are used, they will
be detected as 1-phase input. When X1, X3, x5, X7 are used, X0, X2, X4, X6 will be applied
together as AB-phase input.

16-bit instruction: -32,768~32,767. 32-bit instruction: -2,147,483,648~2,147,483,647.
When S2 is specified as K0, the pulse will be output continuously regardless of the limit of
pulse number.
24.
When D1220/D1221 = K1 or K2, the positive/negative sign of S2 denotes pulse output direction
(Positive/negative).

28.
While the PLSY instruction is being executed, the output will not be affected if S2 is changed.
To change the pulse output number, stop the PLSY instruction, then change the pulse number.
29.
S1 can be changed during program execution and the change will take effects until the
modified PLSY instruction is being executed.
30.
The ratio of OFF time and ON time of the pulse output is 1:1.
31.
If operand S1, S2 use index F, only 16-bit instruction is available.

3. Instruction Set
32.
There is no limitation on the times of using this instruction, however the program allows only 4
instructions (PLSY, PWM, PLSR) to be executed at the same time. If Y1 is used for several
high speed pulse output instructions, PLC will output according to the execution order of these
instructions.
Program Example:
33.
When X0 = ON, 200 pulses of 1kHz are generated from output Y0, after the pulse output has
been completed, M1029 = ON to set Y20.
34.
When X0 = OFF, pulse output Y0 will immediately stop. When X0 turns ON again, the pulse
output will start from the first pulse.

More explanations for M1347,M1348, M1524, M1525:
Generally when pulse output is completed, PLSY instruction has to be reset so that the
instruction can start pulse output one more time. When M1347, M1348, M1524 or M1525 is
enabled, the associated output terminals (Y0~Y3) will be reset automatically when pulse
output is completed, i.e. the PLSY instruction is reset. When PLC scans to PLSY instruction
again, the pulse output starts automatically. In addition, PLC scans the 4 flags after END
instruction, hence PLSY instruction in continuous pulse output mode requires a delay time of
one scan cycle for next pulse output operation.
The function is mainly used in subroutines or interrupts which require high speed pulse output.

41.
When several pulse output instructions (PLSY, PWM, PLSR) use Y1 or Y3 as the output
device in the same scan cycle, PLC will perform the instruction which is executed first.
42.
When S1≦0, S2≦0 or S1＞S2 , errors will occur (M1067 and M1068 will not be ON) and no
output will be generated from pulse output devices. When S1 = S2, the pulse output device will
be ON continuously.
43.
S1, S2 can be changed when PWM instruction is being executed.
44.
When M1112 = ON, the unit of Y0 output pulse is 10μs, when M1112 = OFF, the unit is 100μs.
45.
When M1070 = ON, the unit of Y1 output pulse is 100μs, when M1070 = OFF, the unit is 1ms.

49.
When M1116 is ON, M1112 and M1113 do not work. The time unit of the pulse output through
Y0 and Y2 is 1μs. DVP-ES2 version 3.00/SS2 version 2.80/SA2 version 2.60/SE version

51.
If M1116 for DVP-SS2 is enabled, the minimum pulse output width should be larger than 20.
Otherwise, due to the limitations on the hardware bandwidth of Y0 and Y2, the output result is
not the correct time width.

Explanations:
52.
PLSR instruction performs a frequency ramp up/down process when positioning. Speed ramp
up process is activated between static status to the target speed. Pulse output persists in
target speed before getting close to target position. When target position is near, speed ramp
down process executes, and pulse output stops when target position is achieved.

When output device is specified with Y0, Y2, the start/end frequency of Y0 is set by D1340 and
start/end frequency of Y2 is set by D1352.
55.
When output device is specified with Y1, Y3, the start/end frequency is 0Hz.
56.
When D1220/D1221 = K1 or K2, positive/negative sign of S2 denotes pulse output direction.

When assigning Y0 and Y2 output mode as Pulse, i.e. D1220 = K0, D1221 = K0, the available
range for S2 is 1~32,767 (16-bit instruction) and 1~2,147,483,647 (32-bit instruction).
59.
When assigning Y0 and Y2 output mode as Pulse/Dir, i.e. D1220 = K1, D1221 = K1, the
available range for S2 is 1~32,767 or -1~-32,768 (16-bit instruction) and 1~2,147,483,647 or
-1~-2,147,483,648 (32-bit instruction)
60.
When assigning output device as Y1 and Y3, the available range for S2 is 1~32,767 (16-bit
instruction) and 1~2,147,483,647 (32-bit instruction).
61.
S3: Ramp up/down time (unit: ms, min. 20ms).
When assigning output device as Y1 and Y3, the set value of ramp up and ramp down time
should be the same.
When assigning output device as Y0 and Y2, and if:
M1348 = OFF (Y0) and M1535 = OFF (Y2), the ramp up and ramp down time should be
the same.
M1348 = ON and M1535 = ON, then S3 specifies ramp up time only. The ramp down time
is specified by value set in D1348 (Y0) and D1349 (Y2).
62.
When M1257 = OFF, ramp up/down curve of Y0 and Y2 is straight line. When M1257 = ON,
ramp up/down curve will be S curve. The ramp up/down curve of Y1 and Y3 is fixed as straight
line
63.
The output will not be affected if S1, S2 or S3 are changed when PLSR instruction is being
executed. PLSR instruction has to be stopped if changing values in S1, S2 or S3 is required.

65.
During the ramp up process, the pulse numbers (frequency x time) of each speed shift may not
all be integer values, but PLC will operate integer value only. In this case, the omitted decimals
will result in errors between each speed shift, i.e. pulse number for each shift may differ due to
this operation. For ensuring the required output pulse number, PLC will fill in pulses as need
automatically in order to correct the deviation.
3-146
3. Instruction Set
66.
There is no limitation on the times of using this instruction in the program. However, only 4
instructions can be executed at the same scan time. When several pulse output instructions
(PLSY, PWM, PLSR) use Y1 as the output device in the same scan cycle, PLC will execute
pulse output according to the driven order of these instructions.
67.
Set value falls out of the available range of operands will be automatically corrected with the
min. or max available value.
Program Example:
68.
When X0 = ON, PLSR performs pulse output on Y0 with a target speed of 1000Hz, output
pulse number D10 and ramp up/down time of 3000ms. Ramp up process begins to increase
1000/20 Hz in every shift and every shift outputs D10/40 pulses for 3000/20 ms.
69.
When X0 = OFF, the output stops immediately and starts from the count value in D1030,
D1031 when PLSR is executed again.

3. Instruction Set
When M1156/M1158 = ON, enable ramp-down pause (Mark function) on Y0/Y2 when X4/X6
receives interrupt signals.
When Mark function is enabled, ramp down time is independent of the ramp up time. Users
can set ramp up time in S3 and ramp down time in D1348/D1349. (Range: 20ms~32767ms)
When Mark function is executed and the ramp-down stop pulses (DD1232/DD1234) are
specified, PLC will execute ramp-down stop with specified pulses after Mark is detected.
However, if DD1232/DD1234 are less than the specified ramp-down time (D1348 / D1349),
PLC will fill DD1232/DD1234 with the value of ramp-down time. In addition, if DD1232/DD1234
is more than the half of total output pulses, PLC will modify DD1232/DD1234 to be less than
half of the total output pulses.
Ramp-down stop pulses (DD1232/DD1234) are 32-bit value. Set value K0 will disable the
Mark function.

Explanations:
When M0 is triggered, Y0 executes pulse output. If external interrupt is detected on X4,
pulse output will perform ramp down process for 10,000 pulses and then stop. M1108 will
be ON to indicate the pause status (ramp down). If no interrupt is detected, Y0 pulse

output will stop after 1,000,000 pulses are completed.
When pulse output ramps down and stops after Mark is detected, M1538 will be ON to
indicate the pause status. If users need to complete the remaining pulses, set OFF the
flag M1108 and pulse output will resume.

Mask function on Y0 will be enabled when D1026 and D1027 are specified with values other
than 0. Mask function is disabled when D1026 and D1027 are specified with 0. If pulse output
process can not reach the target speed, PLC will clear DD1026 to disable the Mask function. If
the Mask range is set to be within the ramp-up section, PLC will automatically modify DD1026
to be longer than the ramp-up section. On the other hand, if DD1026 is set between rampdown section, PLC will modify DD1026 to be the range before the beginning of ramp-down
process. Mask function setting method on Y2 is the same as Y0.

3. Instruction Set
Explanations:
When M0 is triggered, Y0 executes pulse output. When external interrupt is detected on X4
after 50,000 pulses, pulse output will perform ramp down process for 10,000 pulses and then
stop. M1108 will be ON. If no interrupt is detected on X4, Y0 pulse output will stop after
1,000,000 pulses are completed.
Interrupt triggered between 0 ~ 50,000 pulses will be invalid, i.e. no ramp-down process will be
performed before 50,000 pulses are achieved.
Points to note:
1. When Mark function is executed with Mask function, PLC will check the validity of Mask
range first, then ramp-down stop pulses of Mark function. If the above set values exceed
the proper range, PLC will automatically modify the set values after the instruction is
executed.
2. When PLSR or positioning instructions with ramp-up/down section are enabled, the user
can check the pulses of ramp-up section in DD1127 and pulses of ramp-down section in
DD1133.
3. Users can perform single speed positioning when ramp-up/down time setting is not
specified.

D2: The greatest No. of step points in auto mode.
Explanations:
75.
The IST is a handy instruction specifically for the initial state of the step ladder operation
modes.
76.
The range of D1 and D2 : S20~S911, D1 < D2.
77.
IST instruction can only be used one time in a program.

X20
S20
S60
X20: Individual operation (Manual operation)
X24: Continuous operation
X21: Zero return
X25: Zero return start switch
X22: Step operation
X26: Start switch
X23: One cycle operation
X27: Stop switch
When IST instruction is executed, the following special auxiliary relays will be assigned
automatically.
M1040: Movement inhibited
S0: Manual operation/initial state step point
M1041: Movement start
S1: Zero point return/initial state step point
M1042: Status pulse
S2: Auto operation/initial state step point
M1047: STL monitor enable
79.
When IST instruction is used, S10~S19 are occupied for zero point return operation and
cannot be used as a general step point. In addition, when S0~S9 are in use, S0 initiates
“manual operation mode”, S1 initiates “zero return mode” and S2 initiates “auto mode”. Thus,
the three step points of initial state have to be programmed in first priority.
3-152
3. Instruction Set
80.
When S1 (zero return mode) is initialized, i.e. selected, zero return will NOT be executed if any
of the state S10~S19 is ON.
81.
When S2 (auto mode) is initialized, i.e. selected, auto mode will NOT be executed if M1043 =
ON or any of the state between D1 to D2 I is ON.

Flag explanation:
M1040:
Disable step transition. When M1040 = ON, all motion of step points are disabled.
91.
Manual operation mode: M1040 remains ON in manual mode.
92.
Zero return mode/one cycle operation mode: M1040 remains ON in the interval after Auto
Stop and before Auto Start is pressed.
93.
Step operation mode: M1040 remians ON until Auto Start is pressed.
94.
Continuous operation mode: When PLC goes from STOP→RUN, M1040 = ON. When Auto
Start is pressed, M1040 turns OFF.
M1041:
Step transition starts. This special M indicates the transition from step point S2 to the next step
point.
95.
Manual operation mode/Zero return mode: M1041 remians OFF.
96.
Step operation mode/One cycle operation mode: M1041 = ON when Auto Start is pressed.
97.
Continuous operation mode: M1041 stays ON when Auto Start is pressed and turns OFF
when Auto Stop is pressed.
M1042:
Enable pulse operation: When Auto Start is pressed, PLC sents out pulse once for operation. .
M1043:
Zero return completed: M1043 = ON indicates that zero return is completed.
M1044:
Zero point condition: In continuous operation mode, M1044 has to be ON as a condition for enabling
step transition from S2 to the next step point.
M1045:
Disable “all output reset” function.
y
If the machine (not at the zero point) goes,
-
from manual (S0) to zero return (S1)
-
from auto (S2) to manual (S0)
-
from auto (S2) to zero return (S1)
And
M1045 = OFF, any of the S among D1 ~ D2 in action will be reset as well as the output Y.
M1045 = ON, output Y will be retained but the step in action will be reset.
y
If the machine (at the zero point) goes from zero return (S1) to manual (S0), no matter M1045
is ON or OFF, Y output will be retained but the step in action will be reset.

3. Instruction Set
M1046:
Indicates STL(Step Ladder) status. When STL operation is activate, M1046 = ON if any of the step
point S is ON. If M1047 = ON, M1046 also activates to indicate ON status of step points. In addition,
D1040 ~ D1047 records 8 step numbers from the current ON step to the previous 7 ON steps.
M1047:
Enable STL monitoring. When IST instruction executes, M1047 will be forced ON, i.e. M1047
remains ON in every scan cycle as long as IST instruction is executing. This flag is used to monitor
all step points (S).
D1040~D1047:
Records 8 step numbers from the current ON step to the previous 7 ON steps.

D: Start device for storing search
n: Stack length
Explanations:
98.
SER instruction searches for the value stored in S2 from the data stack starting with S1, with a
stack length n. The search results are stored in the 5 registers starting from D
99.
D stores the total of the matched results; D+1 stores the No. of device storing the first matched
result; D+2 stores the No. of device storing the last matched result; D+3 stores the No. of
device storing the smallest value; D+4 stores the No. of device storing the biggest value..
100. If operand S2 uses index F, only 16-bit instruction is available
101. If the instruction applied 32-bit instruction, operands S1, S2, D, n will specify 32-bit registers.
102. The range of operand n: n = 1~256 (16-bit instruction), n = 1~128 (32-bit instruction)
Program Example:
103. When X0 = ON, the data stack D10~D19 are compared with D0 and the result is stored in
D50~D54. If there is no matched result, the content of D50~D52 will all be 0.
104. D53 and D54 store the location of the smallest and biggest value. When there are more than
one smallest and biggest values, the devices with bigger No. will be recorded.

Operands:
S1: Start device of the data table

S2: No. of counter
D: Start device for indicating comparison
n: Groups of data to be compared (n: 1~64)
Explanations:
105. ABSD instruction creates various output wave forms according to the current value of the
counter designated by S2. Usually, the instruction is applied for absolute cam control.
106. 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.
107. When operand S1 uses KnX, KnY, KnM, KnS patterns, Kn should be K4 for 16-bit instruction
and K8 for 32-bit instruction.
Program Example:
108. 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.
109. 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 comparison results will be stored in M10 ~
M13.
110. When X10 = OFF, the original ON/OFF status of M10 ~ M13 will be retained.

Operands:
S1: Start device of the data table
result
S2: No. of counter
D: Start device for indicating comparison
n: Number of data to be compared (n: 1~64)
Explanations:
113. INCD instruction creates various output wave forms according to the current value of the
counter designated by S2. and S2.+1. Usually, the instruction is applied for relative cam control
114. The current value in S2 is compared with the set points specified by S1 (n consecutive devices)
When value in S2 reaches the first set point, S2.+1 counts once for indicating the number of
present section, associated D turns ON, and S2 is reset then counts up from 0 again. When the
drive contact of INCD instruction is OFF, the content in S2. and S2.+1 will be cleared.
115. When operand S1 uses KnX, KnY, KnM, KnS patterns, Kn should be K4 for 16-bit instruction.
116. Operand S2 should be C0~C198 and occupies 2 consecutive counters.
117. When the comparison of n data has been completed, the execution completed flag M1029 =
ON for one scan cycle.
Program Example:
118. Before the execution of INCD instruction, use MOV instruction to write all the set values into
D100 ~ D104 in advance. D100 = 15, D101 = 30, D102 = 10, D103 = 40, D104 = 25.
119. The current value of counter C10 is compared against the set-point value of D100~D104.
Once the current value is equal to the set-point value, C10 will be reset and count up from 0
again. Meanwhile C11 counts once for indicating the number of present section
120. When the content of C11 increase 1, M10~M14 will be ON sequentially. Please refer to the
following timing diagram.
121. When the comparison of 5 data has been completed, the execution completed flag M1029 =
ON for one scan cycle and C11 is reset for next comparison cycle.

Operands:
D: Device No. for storing the ON time of the input
n: setting of multiple (n: K0~K2)
Explanations:
123. The ON time of the external button switch is measured and stored in D + 1(unit: 100ms). Value
in D + 1 is multiplied with a multiple specified by n and stored in D (unit: sec).
124. When n = K0, the value in D + 1(unit: 100ms) is multiplied with 1 and converted to D (unit: sec).
When n = K1, the value in D + 1(unit: 100ms) is multiplied with 10 and converted to D (unit:
sec). When n = K2, the value in D + 1(unit: 100ms) is multiplied with 100 and converted to D
(unit: sec).
125. TTMR instruction can be used max 8 times in a program.
Program Example 1:
126. The duration that input X0 is pressed (ON duration of X0) will be stored in D1. The value in D1,
multiplied by a multiple specified by n, is then moved to D0. In this case, the button switch can be
used to adjust the set value of a timer.
127. When X0 = OFF, the content of D1 will be reset but the content of D0 remains.

Program Example 2:
129. Use TMR instruction to write in 10 groups of set time.
130. Write the set values into D100 ~ D109 in advance
131. The timer resolution is 0.1 sec for timers T0 ~ T9 and 1 sec for the teaching timer.
132. Connect the 1-bit DIP switch to X0 ~ X3 and use BIN instruction to convert the set value of the
switch into a bin value and store it in E.
133. The ON duration (in sec) of X20 is stored in D200.
134. M0 is a pulse for one scan cycle generated when the teaching timer button X20 is released.
135. Use the set number of the DIP switch as the index pointer and send the content in D200 to
D100E (D100 ~ D109).

Explanations:
136. STMR instruction is specifically used for delay-OFF, ON/OFF triggered timer and flashing
circuit.
137. The timer number (S) specified by STMR instruction can be used only once
Program Example:
138. When X20 = ON, STMR sets T0 as the 5 sec special timer.
139. Y0 is the delay-OFF contact. When X20 is triggered, Y0 = ON; When X20 is OFF, Y0 = OFF
after a 5 sec delay.
140. When X20 goes from ON to OFF, Y1 = ON for 5 seconds.
141. When X20 goes from OFF to ON, Y2 = ON for 5 seconds.
142. When X20 goes from OFF to ON, Y3 = ON after a 5 second delay. When X20 turns from ON to

145. When ALT instruction is executed, ON/OFF state of D will be switched which is usually applied
on switching two operation modes, e.g. Start/Stop
146. This instruction is generally used in pulse execution mode (ALTP).

Operands:
S1: Start of ramp signal
consecutive devices)
S2: End of ramp signal
D: Current value of ramp signal (occupies 2
n: Times for scan (n: 1~32,767)
Explanations:
147. This instruction creates a ramp output. A ramp output linearity depends on a consistent scan
time. Therefore, scan time has to be fixed before executing RAMP instruction.
148. When RAMP instruction is executed, the ramp signal will vary from S1 to S2. Current value of
ramp signal is stored in D and D+1 stores the current number of accumulated scans. When
ramp signal reaches S2, or when the drive contact of RAMP instruction turns OFF, the content
in D varies according to the setting of M1026 which is explained later in Points to note.
149. When n specifies a D register, the value in D cannot be modified during the execution of the
instruction. Please modify the content of D when the instruction is stopped.
150. When this instruction is applied with analog output function, Ramp start and Ramp stop
function can be achieved.
Program example:
1.
Before executing the instruction, first drive M1039 = ON to fix the scan time. Use MOV
instruction to write the fixed scan time to the special data register D1039. Assume the scan
time is 30ms and take the below program for example, n = K100, the time for D10 to increase
to D11 will be 3 seconds (30ms × 100).
2.
When X20 goes OFF, the instruction will stop its execution. When X10 goes ON again, the
content in D12 will be reset to 0 for recalculation
3.
When M1026 = OFF, M1029 will be ON to indicate the completion of ramp process and the
content in D12 will be reset to the set value in D10.
4.
Set the Start and End of ramp signal in D10 and D11. When X20 = ON, D10 increases towards
D11, the current value of the variation is stored in D12 and the number of current scans is
stored in D13.

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.
3-174
3. Instruction Set
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)

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: Proportional Value Calculation Function of Multi-point Areas (16-bit values)
Explanation on operands (16-bit values):
S: input value
S+1, S+2….. S+n: set values of multi-point areas. S+1 must be the minimum value, S+2 must
be larger than S+1 and so on. Therefore, S+n must be the maximum value.
D: output value gotten from the proportional value calculation
D+1, D +2 … D+n: the range of values gotten from the proportional value calculation

The explanation of the sample:
1. When input value S is larger than S+1 (S1 for short) and smaller than S+2 (S2 for short),
D+1 (D1 for short) and D+2 (D2 for short), D= ( ( S – S1) x ( D2 – D1 ) / ( S2 – S1 ) ) + D1.
2. When input value S is smaller than S+1, D= D+1; when input value S is larger than S+n,
D= D+n.
3. The operation of instructions uses floating-point values. After the decimal value of the
output values is omitted, the value will be output in the 16-bit form.
K13: Proportional Value Calculation Function of Multi-point Areas (32-bit values)
The explanations of source and destination devices are illustrated as the explanation of K12,
but devices S and D are indicated by 32-bit values.
K14: Proportional Value Calculation Function of Multi-point Areas (floating-point values)
The explanations of source and destination devices are illustrated as the explanation of K12,
but devices S and D are indicated by 32-bit floating-point values.
K16: String combination
Explanation:
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.

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:
Hi-byte Lo-byte

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.

D V P - E S 2 / E X 2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
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 0~9 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:
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.

columns in the table (m2 =1~6) D: Start device for the sorted data n: The No. of column to be
sorted. (n=1~ m2)
Explanations:
154. The sorted data is stored in the m1 × m2 registers starting from the device designated in D.
Therefore, if S and D designate the same register, the sorted results will be the same.
155. SORT instruction is completed after m1 times of scan. Once the SORT instruction is completed,
the Flag M1029 (Execution completed flag) = ON.
156. There is no limitation on the times of using this instruction in the program. However, only one
instruction can be executed at a time
Program Example:
When X0 = ON, the sorting process starts. When the sorting is completed, M1029 will be ON. DO
NOT change the data to be sorted during the execution of the instruction. If the sorting needs to be
executed again, turn X0 from OFF to ON again.

Operands:
S: Start device for key input (occupies 10 consecutive devices)
value
D1: Device for storing keyed-in
D2: Output signal (occupies 11 consecutive devices)
Explanations:
157. This instruction designates 10 external input points (corresponding to decimal numbers 0 ~ 9)
starting from S, connecting to 10 keys respectively. Input point started from S triggers
associated device in D2 and D2 maps to a decimal value, a 4-digit decimal value 0~9,999
(16-bit instruction) or an 8-digit value 0~99,999,999 (32-bit instruction). The decimal value is
stored in D1.
158. There is no limitation on the times of using this instruction in the program, however only one
instruction is allowed to be executed at the same time.
Program Example:
159. Connect the 10 input points starting from X30 to the 10 keys (0 ~ 9). When X20 = ON, the
instruction will be executed and the key-in values will be stored in D0 in BIN form. The key
status will be stored in M10 ~ M19.

160. As shown in the timing diagram below, four keys connected with X35, X33, X31 and X30 are
pressed in order. Therefore, the number 5,301 is generated and stored in D0. 9,999 is the
maximum value allowed for D0. If the entered number exceeds the available range, the
highest digit performs overflow.
161. When X35 is pressed, M15 remains ON until another key is pressed and the rule applies to
other inputs.
162. M20 = ON when any of the keys is pressed.
163. When X20 is OFF, the value in D0 remains unchanged but M10~M20 will be OFF.

(occupies 4 consecutive devices)
D1: The start of output devices
D2: Device for storing key input value
D3: Key input status
(occupies 8 consecutive devices)
Explanations:
164. This instruction creates a 16-key keyboard by a multiplex of 4 consecutive external input
devices from S and 4 consecutive external output devices from D1. By matrix scan, the key
input value will be stored in D2. D3 stores the condition of keys A~F and indicates the key input
status of both 0~9 and A~F..
165. M1029 = ON for a scan cycle every time when a key is pressed.
166. If several keys are pressed, only the first pressed key is valid.
167. D2 maps to a decimal value, a 4-digit decimal value 0~9,999 (16-bit instruction) or an 8-digit
value 0~99,999,999 (32-bit instruction). If the entered number exceeds the available range, i.e.
4 digit in 16-bit and 8 digits in 32-bit instruction, the highest digit performs overflow
168. There is no limitation on the times of using this instruction in the program, but only one
instruction is allowed to be executed in the same scan time.
Program Example:
169. Designate 4 input points X20 ~ X23 and the other 4 output points Y20 ~ Y23 to construct a
16-key keyboard. When X4 = ON, the instruction will be executed and the keyed-in value will
be stored in D0 in BIN form. The key status will be stored in M10 ~ M19.

Points to note:
175. When HKY instruction is executed, 8 scan cycles (matrix scan) are required for reading the
input value successfully. A scan cycle that is too long or too short may cause the input to be
read incorrectly. In this case we suggest the following solutions:
If the scan cycle is too short, I/O may not be able to respond in time, resulting in incorrect input
values. To solve this problem please fix the scan time.
If the scan period is too long, the key may respond slowly. In this case, write this instruction into
the time-interrupt subroutine to fix the execution time for this instruction.
176. The function of flag M1167:
When M1167 = ON, HKY instruction can input hexadecimal value consists of 0~F.
When M1167 = OFF, A~F of HKY instruction are used as function keys.

n: Groups of switches (n = 1~2)
Explanations:
177. This instruction creates 1(2) group of 4-digit DIP switch by the combination of 4(8) consecutive
input points starting from S and 4 consecutive output points starting from D1. The set value will
be read in D2 and the value in n specifies the number of groups (1~2) of the DIP switch.
178. n = K1, D2 occupies 1 register. n = K2, D2 occupies 2 consecutive registers..
179. There is no limitation on the times of using this instruction in the program, however only one
instruction is allowed to be executed at the same scan time.
Program Example:
180. The first group of DIP switches consists of X20 ~ X23 and Y20 ~ Y23. The second group of
switches consists of X24 ~ X27 and Y20 ~ Y23. When X10 = ON, the instruction will be
executed and the set value of the first switch will be read and converted into BIN value then
stored in D20. BIN value of 2nd switch will be stored in D21.

Points to note:
When the terminals to be scanned are relay outputs, the following program methods can be applied:
183. When X30 = ON, DSW instruction will be executed. When X30 goes OFF, M10 remains ON
until the current scan cycle of output terminals is completed..
184. If the drive contact X30 uses button switch, M10 turns off only when the current scan cycle on
outputs is completed, so that a correct value from DIP switch can be read. In addition, the
continuous scan cycle on outputs will be performed only when the drive contact is pressed and
held. Applying this method can reduce the driving frequency of relay outputs so as to extend to
life-span of relays.

Operands:
S: Source device storing the value to be displayed in 7-segment display
D: Output device for
7-segment display
n: Configuration setting of output signal (n = 0~7)
Explanations:
185. This instruction occupies 8 or 12 consecutive external output points starting from D for
displaying the data of 1 or 2 sets of 4-digit 7-segment display. Every digit of the 7-segment
display carries a “Drive” which converts the BCD codes into 7-segment display signal. The
drive also carries latch control signals to retain the display data of 7-segment display.
186. n specifies the number of sets of 7-segment display (1 set or 2 sets ), and designates the
positive / negative output of PLC and the 7-segment display.
187. When there is 1 set of 4-digit output, 8 output points will be occupied. When there are 2 sets
of 4-digit output, 12 output points will be occupied
188. When the instruction is executed, the output terminals will be scanned circularly. When the
drive contact goes from OFF to ON again during the execution of instruction, the scan will
restart from the beginning of the output terminals.
189. Flag: When SEGL is completed, M1029 = ON for one scan cycle.
190. There is no limitation on the times of using this instruction in the program, however only one
instruction is allowed to be executed at a time.
Program Example:
191. When X20 = ON, SEGL instruction executes and Y24~Y27 forms an output scan loop for
7-segment display. The value of D10 will be mapped to Y20~Y23, converted to BCD code
and sent to the 1st set of 7-segment display. The value of D11 will be mapped to Y30~Y33,
converted to BCD code and sent to the 2nd set of 7-segment display. If the values in D10 and
D11 exceed 9,999, operational error will occur.

192. When X20 = ON, Y24~Y27 will be scanned in circles automatically. Each circle requires 12
scan cycles. M1029 = ON for a scan cycle whenever a circle is completed.
193. When there is 1 set of 4-digit 7-segment display, n = 0 ~ 3
Connect the 7-segment display terminals 1, 2, 4, 8 in parallel then connect them to Y20 ~ Y23 on
PLC. After this, connect the latch terminals of each digit to Y24 ~ Y27 on PLC.
1. When X20 = ON, the content of D10 will be decoded through Y20 ~ Y23 and sent to
7-segment display in sequence by the circulation of Y24 ~ Y27
194. When there are 2 sets of 4-digit 7-segment display, n = 4 ~ 7
Connect the 7-segment display terminals 1, 2, 4, 8 in parallel then connect them to Y30 ~ Y33 on
PLC. After this, connect the latch terminals of each digit to Y24 ~ Y27 on PLC.
2. The content in D10 is sent to the 1st set of 7-segment display. The content in D11 is sent to
the 2nd set of 7-segment display. If D10 = K1234 and D11 = K4321, the 1st set will display 1 2
3 4, and the 2nd set will display 4 3 2 1.

Points to note:
195. For executing this instruction, scan time must be longer than 10ms. If scan time is shorter
than 10ms, please fix the scan time at 10ms.
196. If the output points of PLC is transistor output, please apply proper 7-segment display.
197. Operand n is used for setting up the polarity of the transistor output and the number of sets of
the 4-digit 7-segment display.
198. The output point must be a transistor module of NPN output type with open collector outputs.
The output has to connect to a pull-up resistor to VCC (less than 30VDC). When wiring,
output should connect a pull-high resistor to VCC (less than 30VDC). Therefore, when output
point Y is ON, the output signal will be LOW.

setting of output signal (n = 0~3). Please refer to explanations of SEGL instruction for the n usage.
Explanations:
1.
ARWS instruction displays the value set in device D1 on a set of 4-digit 7 segment display.
PLC automatically converts the decimal value in D1 to BCD format for displaying on the 7
segment display. Each digit of the display can be modified by changing the value in D1 through
the operation of the arrow switch.
2.
Number of D2 only can be specified as a multiple of 10, e.g. Y0, Y10, Y20…etc.
3.
Output points designated by this instruction should be transistor output.
4.
When using this instruction, please fix the scan time, or place this instruction in the timer
interruption subroutine (I610/I699, I710/I799).
5.
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.
Program Example:
1.
When the instruction is executed, X20 is defined as the Minus key, X21 is defined as the Add
key, X22 is defined as the Right key and X23 is defined as the Left key. The keys are used to
modify the set values (range: 0 ~ 9,999) stored in D20..
2.
When X0 = ON, digit 103 will be the valid digit for setup. When Left key is pressed, the valid
digit will shift as the following sequence: 103→100→101→102→103→100.
3.
When Right key is pressed, the valid digit will shift as the following sequence: 103→102→101
→100→103→102. Besides, the digit indicators (LED, Y24 to Y27) will be ON for indicating the
position of the valid digit during shift operation.
4.
When Add key is pressed, the content in the valid digit will change as 0 → 1 → 2 … → 8 →
9 → 0 →1. When Minus key is pressed, the content in the valid digit will change as 0 → 9
→ 8 … → 1 → 0 → 9. The changed value will also be displayed in the 7-segment display.

Operands:
S: Device for storing ASCII code (occupies 4 consecutive devices)
D: External ASCII code output
points (occupies 10 consecutive devices)
Explanations:
1.
This instruction will output the ASCII codes in the 4 registers starting from S through output
points started from D.
2.
D0 ~ D7 map to source data (ASCII code) directly in order, D10 is the scan signal and D11 is the
execution flag.
3.
This instruction can only be used twice in the program.
4.
Flags: M1029 (PR execution completed); M1027 (PR output mode selection).
Program Example 1:
1.
Use API 76 ASC to convert A ~ H into ASCII codes and store them in D0 ~ D3. After this, use
this instruction to output the codes in sequence.
2.
When M1027 = OFF and X20 = ON, the instruction will designate Y20 (lowest bit) ~ Y27
(highest bit) as the output points and Y30 as scan signals, Y31 as execution flag. In this mode,
users can execute an output for 8 letters in sequence..
3.
If X20 turns from ON → OFF during the execution of the instruction, the data output will be
interrupted, and all the output points will be OFF. When X20 = ON again, the data output will
start from the first letter again.

Program Example 2:
1.
PR instruction supports ASCII data output of 8-bit data string when M1027 = OFF. When
M1027 = ON, the PR instruction is able to execute an output of 1~16 bit data string.
2.
When M1027 = ON and X20 = ON, this instruction will designate Y20 (lowest bit) ~ Y27
(highest bit) as the output points and Y30 as scan signals, Y31 as execution flag. In this mode,
users can execute an output for 16 letters in sequence. In addition, if the drive contact X20 is
OFF during execution, the data output will stop until a full data string is completed.
3.
The data 00H (NULL) in a data string indicates the end of the string and the letters coming
after will not be processed.
4.
If the drive contact X20 is OFF during execution, the data output will stop until a full data string
is completed. However, if X20 remains ON, execution completed flag M1029 will not be active
as the timing diagram below.

Operands:
S: Start device for data to be sent
data to be received
m: Length of data to be sent (m = 0~256)
D: Start device for
n: Length of data to be received (n = 0~255)
Explanations:
1.
RS instruction is used for data transmitting and receiving between PLC and external/peripheral
equipment (AC motor drive, etc.). Users have to pre-store word data in registers starting from
S, set up data length m, specify the data receiving register D and the receiving data length n.
2.
RS instruction supports communication on COM1 (RS-232), COM2 (RS-485) and COM3
(RS-485, ES2/EX2/SA2). (COM3 is only applicable to DVP-ES2/EX2/SA2/SE, and is not
applicable to DVP-ES2-C.)
3.
Designate m as K0 if data sending is not required. Designate n as K0 if data receiving is not
required.
4.
Modifying the communication data during the execution of RS instruction is invalid.
5.
There is no limitation on times of using this instruction, however, only 1 instruction can be
executed on one communication port at the same time..
6.
If the communication format of the peripheral device is Modbus, DVP series PLC offers handy
communication instructions MODRD, MODWR, and MODRW, to work with the device.
7.
If the connected peripheral devices are Delta VFD series products, there are several
communication instructions available including FWD, REV, STOP, RDST and RSTEF.
Program Example 1: COM2 RS-485
1.
Write the data to be transmitted in advance into registers starting from D100 and set M1122
(Sending request) as ON.
2.
When X10 = ON, RS instruction executes and PLC is ready for communication. D100 will then
start to send out 10 data continuously. When data sending is over, M1122 will be automatically
reset. (DO NOT apply RST M1122 in program). After approximate 1ms, PLC will start to
receive 10 data and store the data in 10 consecutive registers starting from D120.

D V P - E S 2 / E X 2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
3.
When data receiving is completed, M1123 will automatically be ON. When data processing on
the received data is completed, M1123 has to be reset (OFF) and the PLC will be ready for
communication again. However, DO NOT continuously execute RST M1123, i.e. it is
suggested to connect the RST M1123 instruction after the drive contact M1123.

Switching between 8-bit mode (M1161 = ON) and 16-bit mode (M1161 = OFF)
8-bit mode:
1.
STX (Start of Text) and ETX (End of text) are set up by M1126 and M1130 together with
D1124~D1126. When PLC executed RS instruction, STX and ETX will be sent out
automatically.
2.
When M1161 = ON, only the low byte (lower 8 bits) is valid for data communication, i.e. high
byte will be ignored and low byte will be received and transmitted.

When RS instruction is applied for communication between PLC and peripheral devices on
COM2 RS-485, usually STX (Start of the text) and ETX (End of the text) have to be set into
communication format. In this case, b8~10 of D1120 should be set to 1, so that users can set
up STX/ETX as user-defined or system-defined by using M1126, M1130, and D1124~D1126.
For settings of M1126 and M1130, please refer to the following table.

CRC checksum: Starting from Address and ending at Data Content. The calculation is as follows:
Step 1: Set the 16-bit register (CRC register) = FFFFH
Step 2: Operate XOR on the first 8-bit message (Address) and the lower 8 bits of CRC
register. Store the result in the CRC register.
Step 3: Right shift CRC register for a bit and fill “0” into the highest bit.
Step 4: Check the lowest bit (bit 0) of the shifted value. If bit 0 is 0, fill in the new value
obtained at step 3 to CRC register; if bit 0 is NOT 0, operate XOR on A001H and the
shifted value and store the result in the CRC register.
Step 5: Repeat step 3 – 4 to finish all operation on all the 8 bits.

value obtained in the CRC register is the CRC checksum. Care should be taken when
placing the LOW byte and HIGH byte of the obtained CRC checksum.

Explanations:
1.
This instruction sends the content in S to D in the form of octal system
2.
The start device of X, Y, M in KnX, KnY, KnM format should be a multiple of 10, e.g. X20, M20,
Y20.
3.
When operand S is specified as KnX, operand D should be specified as KnM.
4.
When operand S is specified as KnM, operand D should be specified as KnY.

Operands:
S: Source device
D: Destination device
n: Number of nibbles to be converted (n = 1~256)
Explanations:
1.
16-bit conversion mode: When M1161 = OFF, the instruction converts every nibble of the Hex
data in S into ASCII codes and send them to the higher 8 bits and lower 8 bits of D. n = the
converted number of nibbles.
2.
8-bit conversion mode: When M1161 = ON, the instruction converts every nibble of the Hex
data in S into ASCII codes and send them to the lower 8 bits of D. n = the number of converted
nibbles. (All higher 8 bits of D = 0).
3.
Flag: M1161 (8/16 bit mode switch)
4.
Available range for Hex data: 0~9, A~F
Program Example 1:
1.
M1161 = OFF, 16-bit conversion.
2.
When X0 = ON, convert the 4 hex values (nibbles) in D10 into ASCII codes and send the result
to registers starting from D20.

Operands:
S: source data
D: Destination device for storing check sum
n: Number of byte (n = 1~256)
Explanations:
1.
This instruction performs a sum check for ensuring the validity of the communication data.
2.
16-bit conversion: If M1161 = OFF, n bytes of data starting from low byte of S will be summed
up, the checksum is stored in D and the parity bits are stored in D+1.
3.
8-bit conversion: If M1161 = ON, n bytes of data starting from low byte of S (only low byte is
valid) will be summed up, the check sum is stored in D and the parity bits are stored in D+1.
Program Example 1:
1.
M1161 = OFF, 16-bit conversion.
2.
When X0 = ON, 6 bytes from low byte of D0 to high byte of D2 will be summed up, and the
checksum is stored in D100 while the parity bits are stored in D101.

Operands:
S: Variable resistor number (0~1)
D: Destination device for storing read value
Explanations:
1.
VRRD instruction is used to read the two variable resistors on PLC. The read value will be
converted as 0 ~ 255 and stored in destination D.
2.
If the VR volume is used as the set value of timer, the user only has to turn the VR knob and
the set value of timer can be adjusted. When a value bigger than 255 is required, plus D with a
certain constant.
3.
Flags: M1178 and M1179. (See the Note)
Program Example:
1.
When X0 = ON, the value of VR No.0 will be read out, converted into 8-bit BIN value (0~255),
and stored in D0.
2.
When X1 = ON, the timer which applies D0 as the set value will start timing.

Operands:
S: Variable resistor number (0~1)
D: Destination device for storing scaled value
Explanations:
VRSC instruction reads the scaled value (0~10) of the 2 VRs on PLC and stores the read data in
destination device D as an integer, i.e. if the value is between 2 graduations, the value will be
rounded off.
Program Example 1:
When X0 = ON, VRSC instruction reads the scaled value (0 to10) of VR No. 0 and stores the read
value in device D10.

Program Example 2:
Apply the VR as digital switch: The graduations 0~10 of VR correspond to M10~M20, therefore only
one of M10 ~M20 will be ON at a time. When M10~M20 is ON, use DECO instruction (API 41) to
decode the scaled value into M10~M25.
1.
When X0 = ON, the graduation (0~10) of VR No.1 will be read out and stored in D1.
2.
When X1 = ON, DECO instruction will decode the graduation (0~10) into M10~M25.

consecutive devices, for 32-bit instruction, uses 21 consecutive devices)
D: Output value (MV)
Explanations:
1.
This instruction is specifically for PID control. PID operation will be executed only when the
sampling time is reached. PID refers to “proportion, integration and derivative”. PID control is
widely applied to many mechanical, pneumatic and electronic equipment.
2.
After all the parameters are set up, PID instruction can be executed and the results will be
stored in D. D has to be unlatched data register. (If users want to designate a latched data
register area, please clear the latched registers to 0 in the beginning of user program.
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
= OFF, the instruction will not be executed and the previous data in D150 will stay intact.

Points to note:
1.
There is no limitation on the times of using this instruction. However, the register No.
designated in S3~ S3+19 cannot be repeated.
2.
For 16-bit instruction, S3 occupies 20 registers. In the program example above, the area
designated in S3 is D100 ~ D119.
3.
Before the execution of PID instruction, users have to transmit the parameters to the
designated register area by MOV instruction. If the designated registers are latched, use
MOVP instruction to transmit all parameters only once

7.
PID instruction can be used in interruption subroutines, step ladders and CJ instruction.
8.
The maximum error of sampling time TS = - (1 scan time + 1ms) ~ + (1 scan time). When the
error affects the output, please fix the scan time or execute PID instruction in timer interrupt.
9.
PV of PID instruction has to be stable before PID operation executes. If users need to take the
value input from AIO modules for PID operation, care should be taken on the A/D conversion
time of these modules
10.
For 32-bit instruction, S3 occupies 21 registers. In the program example above, the area
designated in S3 will be D100 ~ D120. Before the execution of PID instruction, users have to
transmit the parameters to the designated register area by MOV instruction. If the designated
registers are latched, use MOVP instruction to transmit all parameters only once.

The equation above illustrates that this operation is different from a general PID
operation on the application of the derivative value. To avoid the fault that the transient
derivative value could be too big when a general PID instruction is first executed, our PID
instruction monitors the derivative value of the PV. When the variation of PV is excessive, the
instruction will reduce the output of MV/.

Notes and suggestion:
1.
S3 + 3 can only be the value within 0 ~ 30,000.
2.
There are a lot of circumstances where PID instruction can be applied; therefore, please
choose the control functions appropriately. For example, when users select parameter
auto-tuning for the temperature (S3 + 4 = K3), the instruction can not be used in a motor control
environment otherwise improper control may occur.
3.
When you adjust the three main parameters, KP, KI and KD (S3 + 4 = K0 ~ K2), please adjust KP
first (according to your experiences) and set KI and KD as 0. When the output can roughly be
controlled, proceed to increase KI and KD (see example 4 below for adjustment methods). KP =
100 refers to 100%, i.e. the proportional gain to the error is 1. KP < 100% will decrease the
error and KP > 100% will increase the error
4.
When temperature auto-tuning function is selected(S3 + 4 = K3, K4), it is suggested that
store the parameters in D register in latched area in case the adjusted parameters will
disappear after the power is cut off. There is no guarantee that the adjusted parameters are
suitable for every control requirement. Therefore, users can modify the adjusted parameters
according to specific needs, but it is suggested to modify only KI or KD.
5.
PID instruction has to be controlled with many parameters; therefore care should be taken
when setting each parameter in case the PID operation is out of control.

Set KI and KD as 0, and KP as 5, 10, 20, 40. Record the SV and PV respectively and the results are
as the figure below.

Step 2:
When KP is 40, response overshoot occurs, so we will not select it.
When KP is 20, PV response is close to SV and won’t overshoot, but transient MV will be to large
due to a fast start-up. We can put it aside and observe if there are better curves.
When KP is 10, PV response is close to SV and is smooth. We can consider using it.
When KP is 5, the response is too slow. So we won’t use it.
Step 3:
Select KP = 10 and increase KI gradually, e.g. 1, 2, 4, 8. KI should not be bigger than KP. Then,
increase KD as well, e.g. 0.01, 0.05, 0.1, 0.2. KD should not exceed 10% of KP. Finally we obtain the
figure of PV and SV below.

Application 1:
PID instruction in pressure control system. (Use block diagram of example 1)
Control purpose:
Enabling the control system to reach the target pressure.
Control properties:
The system requires a gradual control. Therefore, the system will be overloaded or out of
control if the process progresses too fast.
Suggested solution:
Solution 1: Longer sampling time
Solution 2: Using delay instruction. See the figure below

Application 2:
Speed control system and pressure control system work individually (use diagram of Example 2)
Control purpose:
After the speed control operates in open loop for a period of time, adding pressure control
system (PID instruction) to perform a close loop control.
Control properties:
Since the speed and pressure control systems are not interrelated, we have to structure an
open loop for speed control first following by a close loop pressure control. If users afraid that
the pressure control system changes excessively, consider adding the SC ramp-up function
illustrated in Application 1 into this control. See the control diagram below.

Application 3:
Using auto-tuning for temperature control
Control purpose:
Calculating optimal parameter of PID instruction for temperature control
Control properties:
Users may not be familiar with a new temperature environment. In this case, selecting
auto-tuning (S3+4 = K3) for an initial adjustment is suggested. After initial tuning is completed,
the instruction will auto modify control mode to the mode exclusively for adjusted temperature
(S3+4 = K4). In this example, the control environment is a heating oven. See the example
program below.

3. Instruction Set
From the figure above, we can see that the temperature control after auto-tuning is working fine and
it spent only 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, temperature control works
fine and costs only 20 minutes same as that in 80°C.

S2: Set value (K-2,147,483,648~K2,147,483,647, D0~D9,999)
Explanations:
1.
DCNT is the startup instruction for the 32-bit counters C200 to C254.
2.
For general counting up/down counters C200~C231(SS2/SA2/SE/SX2: C200~C232), the
present value will plus 1 or minus 1 according to the counting mode set by flags
M1200~M1231 when instruction DCNT is executed.
3.
For high speed counters C232~C254(SS2/SA2/SE/SX2: C233~C254), when the specified
high speed counter input is triggered by pulse, the counters will start counting. For details
about high-speed input terminals (X0~X7) and counting modes (count up/down), please refer
to section 2.12 C (Counter).
4.
When DCNT instruction is OFF, the counter will stop counting, but the count value will not be
cleared. Users can use RST instruction to remove the count value and reset the contact, or
use DMOV instruction to move a specific value into the register. For high-speed counters
C232~C254, use specified external input point to clear the count value and reset the contacts.

Operands:
S1: Device address (K0~K254)
S2: Data address
n: Data length (K1＜n≦K6)
Explanations:
1.
MODRD instruction supports COM2 (RS-485).
2.
MODRD is an instruction exclusively for peripheral communication equipment in MODBUS
ASCII/RTU mode. The built-in RS-485 communication ports in Delta VFD drives (except for
VFD-A series) are all compatible with MODBUS communication format. MODRD can be used
for communication (read data) of Delta drives.
3.
If the address of S2 is illegal for the designated communication device, the device will respond
with an error, PLC will record the error code in D1130 and M1141 will be ON.
4.
The feedback (returned) data from the peripheral equipment will be stored in D1070 ~ D1085.
After data receiving is completed, PLC will check the validity of the data automatically. If there
is an error, M1140 will be ON.
5.
The feedback data are all ASCII codes in ASCII mode, so PLC will convert the feedback data
into hex data and store them in D1050 ~ D1055. D1050 ~ D1055 is invalid in RTU mode.
6.
If peripheral device receives a correct record (data) from PLC after M1140/M1141 = ON, the
peripheral device will send out feedback data and PLC will reset M1140/M1141 after the
validity of data is confirmed.
7.
There is no limitation on the times of using this instruction, but only one instruction can be
executed at a time on the same COM port.
8.
Rising-edge contact (LDP, ANDP, ORP) and falling-edge contact (LDF, ANDF, ORF) can not
be used with MODRD instruction, otherwise the data stored in the receiving registers will be
incorrect.
9.
For associated flags and special registers, please refer to Points to note of API 80 RS
instruction.

Operands:
S1: Device address (K0~K254)
S2: Data address
n: Data to be written
Explanations:
1.
MODWR instruction supports COM2 (RS-485).
2.
MODWR is an instruction exclusively for peripheral communication equipment in MODBUS
ASCII/RTU mode. The built-in RS-485 communication ports in Delta VFD drives (except for
VFD-A series) are all compatible with MODBUS communication format. MODRD can be used
for communication (write data) of Delta drives.
3.
If the address of S2 is illegal for the designed communication device, the device will respond
with an error, PLC will record the error code in D1130 and M1141 will be ON. For example, if
8000H is invalid to VFD-B, M1141 will be ON and D1130 = 2. For error code explanations,
please see the user manual of VFD-B.
4.
The feedback (returned) data from the peripheral equipment will be stored in D1070 ~ D1085.
After data receiving is completed, PLC will check the validity of the data automatically. If there
is an error, M1140 will be ON
5.
If peripheral device receives a correct record (data) from PLC after M1140/M1141 = ON, the
peripheral device will send out feedback data and PLC will reset M1140/M1141 after the
validity of data is confirmed.
6.
There is no limitation on the times of using this instruction, but only one instruction can be
executed at a time on the same COM port.
7.
If rising-edge contacts (LDP, ANDP, ORP) or falling-edge contacts (LDF, ANDF, ORF) is used
before MODWR instruction, sending request flag M1122 has to be executed as a requirement.
8.
For associated flags and special registers, please refer to Points to note of API 80 RS

M1177 = OFF (Default), FWD, REV, STOP instructions support COM2(RS-485).
2.
M1177= ON, FWD, REV, STOP instructions support COM2(RS-485), COM3(RS-485).
3.
M1177 has to be set up in advance for selecting the target model of VFD. When M1177 = OFF
(Default), FWD, REV, STOP instructions support Delta’s VFD-A inverter. When M1177 = ON,
these instructions support other models of VFD inverters, e.g. VFD-B, VFD.
4.
There is no limitation on the times of using FWD, REV, STOP instruction, however only one
instruction can be executed on single COM port at a time.
3-278
3. Instruction Set
5.
If rising-edge (LDP, ANDP, ORP) or falling-edge (LDF, ANDF, ORF) contacts are used before
FWD, REV, STOP instructions, sending request flags M1122 (COM2) / M1316 (COM3) has to
be enabled in advance for obtaining correct operation.
6.
For detailed information of associated flags and special registers, please refer to RS
instruction.
7.
M1177 = OFF, only Delta VFD-A is supported and the definition of each operand is:
a)
S1 = Address of VFD-A. Range of S1: K0 ~ K31
b)
S2 = Operation frequency of VFD. Set value for VFD A-type inverter: K0 ~ K4,000
(0.0Hz ~ 400.0Hz).
c)
n = Communication mode. Range: K1 ~ K2. n = 1: communicate with VFD at designated
address. n = 2: communicate with all connected VFDs. .
d)
The feedback data from the peripheral equipment will be stored in D1070 ~ D1080 After
data receiving is completed, PLC will check if all data are correct automatically. If there
is an error, M1142 will be ON. When n = 2, PLC will not receive any data.

M1177 = OFF (Default), RSTEF instruction supports COM2(RS-485).
2.
M1177= ON, RSTEF instruction supports COM2(RS-485), COM3(RS-485).
3.
M1177 has to be set up in advance for selecting the target model of VFD. When M1177 = OFF
(Default), RSTEF instruction supports Delta’s VFD-A inverter. When M1177 = ON, these
instructions support other models of VFD inverters, e.g. VFD-B, VFD.
4.
There is no limitation on the times of using RSTEF instruction, however only one instruction
can be executed on single COM port at a time.
5.
If rising-edge (LDP, ANDP, ORP) or falling-edge (LDF, ANDF, ORF) contacts are used before
RSTEF instruction, sending request flags M1122 (COM2) / M1316 (COM3) has to be enabled
in advance for obtaining correct operation.
6.
For detailed information of associated flags and special registers, please refer to RS
instruction.
7.
M1177 = OFF, only Delta VFD-A is supported and the definition of each operand is:
a)
S1 = Address of VFD-A. Range of S1: K0 ~ K31
b)
n = Communication mode. Range: K1 ~ K2. n = 1: communicate with VFD at designated
address. n = 2: communicate with all connected VFDs. .
c)
RSTEF is a handy communication instruction used for reset when errors occur in AC
motor drive operation.
d)
The feedback data from the peripheral equipment will be stored in D1070 ~ D1080.
When n = 2, PLC will not receive any data.
8.
M1177 = ON, other Delta VFDs are supoported
S1 = Address of VFD. Range of S1: K0 ~ K255, when S1 is specified as K0, PLC will
broadcast to all connected VFDs

Operands:
S: Starting device for ASCII mode checksum
n: Data length for LRC operation (n = K1~K256)
D: Starting device for storing the operation result
Explanations:
1.
n: n must be an even number. If n is out of range, an error will occur and the instruction will not
be executed. At this time, M1067 and M1068 = ON and error code H’0E1A will be recorded in
D1067.
2.
16-bit mode: When LRC instruction operates with M1161 = OFF, hexadecimal data starting
from S is divided into high byte and low byte and the checksum operation is operated on n
number of bytes. After this, operation result will be stored in both hi-byte and low byte of D.
3.
8-bit mode: When LRC instruction operates with M1161 = ON, hexadecimal data starting from
S is divided into high byte (invalid) and low byte and the checksum operation is operated on n
number of low bytes. After this, operation result will be stored in low bytes of D (Consecutive 2
registers).

Operands:
S: Starting device for RTU mode checksum
n: Data length for CRC operation (n = K1~K256)
D:
Starting device for storing the operation result
Explanations:
1.
n: n must be an even number. If n is out of range, an error will occur and the instruction will not
be executed. At this time, M1067 and M1068 = ON and error code H’0E1A will be recorded in
D1067.
2.
16-bit mode: When CRC instruction operates with M1161 = OFF, hexadecimal data starting
from S is divided into high byte and low byte and the checksum operation is operated on n
number of bytes. After this, operation result will be stored in both hi-byte and low byte of D.
3.
8-bit mode: When CRC instruction operates with M1161 = ON, hexadecimal data starting from
S is divided into high byte (invalid) and low byte and the checksum operation is operated on n
number of low bytes. After this, operation result will be stored in low bytes of D (Consecutive 2
registers).

Explanations:
1.
The data of S is compared to the data range of S1 ~ S2 and the result (＞, ＝, ＜) is indicated

Explanation:
1.
The instruction converts the decimal floating point value in S to a binary floating point value
and stores the results in the register specified by D.
2.
For example, S = 1234, S +1 = 3. The decimal floating point value will be: 1.234 x 106
3.
D must be binary floating point format. S and S +1 represent the real number and exponent of
the floating point number.
4.
EBIN instruction is the specific instruction used to convert decimal floating point value to binary
floating point value
5.
Range of real number: -9,999 ~ +9,999. Range of exponent: - 41 ~ +35. Range of PLC decimal
floating point value. If the conversion result is 0, zero flag M1020 = ON.
Program Example 1:
When X1 = ON, the decimal floating point value in (D1, D0) will be converted to binary floating point
and the conversion result is stored in (D3, D2).

Operands:
S1: Dividend
S2: Divisor
D: Quotient and Remainder
Explanation:
1.
S1 ÷ S2 = D. The floating point value in S1 is divided by the floating point value in S2 and the
result is stored in D. The division is conducted in binary floating point format.
2.
If S1 or S2 is designated as constant K or H, the instruction will convert the constant into a
binary floating point value before the operation.
3.
If S2 = 0, operation error will occur, the instruction will not be executed
4.
Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)
If absolute value of the result exceeds max. floating point value, carry flag M1022 = ON.
If absolute value of the result is less than min. floating point value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example 1:
When X1 = ON, binary floating point value of (D1, D0) is divided by binary floating point (D11, D10)
and the quotient and remainder is stored in (D21, D20).

Operands:
S: Exponent
D: Operation result
Explanations:
1.
The base is e = 2.71828 and exponent is S
2.
EXP [ S +1, S ] = [ D +1, D ]
3.
Both positive and negative values are valid for S. Register D has to be 32-bit format. Operation
is conducted in floating point value, so the value in S needs to be converted into floating value
before exponent operation.
4.
The content in D: e S, e =2.71828 and S is the specified exponent..
5.
Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag).
If absolute value of the result is larger than max. floating value, carry flag M1022 = ON.
If absolute value of the result is smaller than min. floating value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example:
1.
When M0 = ON, convert (D1, D0) to binary floating value and save the result in (D11, D10).
2.
When M1= ON, perform exponent operation with (D11, D10) as the exponent. The value is
saved in register (D21, D20) in binary floating format.
3.
When M2 = ON, convert the value in (D21, D20) into decimal floating point value and save the
result in (D31, D30). (At this time, D31 indicates powers of 10 for D30)

Explanations:
1.
Perform natural logarithm (LN) operation on operand S:
LN[S +1, S ]=[ D +1, D ]
2.
Only a positive number is valid for S. Register D has to be 32-bit format. Operation is
conducted in floating point value, so the value in S needs to be converted into floating value
before natural logarithm operation.
3.
eD = S. The content of D = LN S, where the value in S is specified by users.
4.
Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag).
If absolute value of the result is larger than max. floating value, carry flag M1022 = ON.
If absolute value of the result is smaller than min. floating value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON
Program Example:
1.
When M0 = ON, convert (D1, D0) to binary floating value and save the result in (D11, D10).
2.
When M1= ON, perform natural logarithm operation with (D11, D10) as the antilogarithm. The
value is saved in register (D21, D20) in binary floating format.
3.
When M2 = ON, convert the value in (D21, D20) into decimal floating point value and save the

Explanations:
1.
Perform logarithm operation with S1 as the base and S2 as the antilogarithm and save the
result in D.
2.
Only a positive number is valid for S. Register D has to be 32-bit format. Operation is
conducted in floating point value, so the value in S needs to be converted into floating value
before logarithm operation.
3.
Logarithm operation: S1D = S2, D = ?

Example: Assume S1 = 5, S2 = 125, S1D = S2, D = ?
4.
5D = 125
D = LogS1S2 = log5125 = 3.
Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag).
If absolute value of the result is larger than max. floating value, carry flag M1022 = ON.
If absolute value of the result is smaller than min. floating value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example:
1.
When M0 = ON, convert (D1, D0) and (D3, D2) to binary floating value and save the result in
register (D11, D10) and (D13, D12) individually.
2.
When M1= ON, perform logarithm operation with (D11, D10) as base and (D13, D12) as
antilogarithm. The results are saved in register (D21, D20) in binary floating format.

Operands:
S: Source device
D: Operation result
Explanations:
1.
This instruction performs a square root operation on the floating point value in S and stores the
result in D. All data will be operated in binary floating point format and the result will also be
stored in floating point format.
2.
If the source device S is specified as constant K or H, the integer value will automatically be
converted to binary floating value.
3.
If operation result of D is 0 (zero), Zero flag M1020 = ON.
4.
S can only be a positive value. Performing any square root operation on a negative value will
result in an “operation error” and instruction will not be executed. M1067 and M1068 = ON and
error code “0E1B” will be recorded in D1067.
5.
Flags: M1020 (Zero flag), M1067 (Program execution error), M1068 (Execution Error Locked)
Program Example 1:

Explanations:
1.
Perform power operation on binary floating value S1 and S2 and save the result in D.
POW [S1+1, S1 ]^[ S2+1, S2 ] = D
2.
Only a positive number is valid for S. Register D has to be 32-bit format. Operation is
conducted in floating point value, so the value in S1 and S2 needs to be converted into floating
value before power operation.
3.
Example of power operation:
When S1S2 = D, D = ? Assume S1 = 5, S2 = 3, D = 53 =125
4.
Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag).
If absolute value of the result is larger than max. floating value, carry flag M1022 = ON.
If absolute value of the result is smaller than min. floating value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example:
1.
When M0 = ON, convert (D1, D0) and (D3, D2) to binary floating value and save the result in
register (D11, D10) and (D13, D12) individually.
2.
When M1 = ON, perform power operation with (D11, D10) as base and (D13, D12) as
exponent. The value is saved in register (D21, D20) in binary floating format.
3.
When M2 = ON, convert the value in (D21, D20) into decimal floating point value and save the

Operands:
S: Delay time, unit: 0.1ms (K1~K1000)
Explanations:
When DELAY instruction executes, in every scan cycle, the execution of the program after DELAY
instruction will be delayed according to the delay time.
Program Example:
When interrupt input X0 is triggered from OFF to ON, interrupt subroutine executes DELAY
instruction first, therefore the program after DELAY instruction (X1 = ON, Y0 = ON…) will be delayed
for 2ms.

Points to note:
1.
User can adjust the delay time according to the actual needs.
2.
The delay time of DELAY instruction could be increased due to the execution of
communication, high-speed counter and high-speed pulse output instructions.
3.
The delay time of DELAY instruction could be increased due to the delay of transistor or relay
when external output (transistor or relay) is specified.

Operands:
S1: Width of output pulse
S2: Pulse output cycle (occupies 3 devices)
D: Pulse output device
Explanations:
1.
When GPWM instruction executes, pulse output will be executes on device specified by D
according to pulse output width S1 and pulse output cycle S2.
2.
S1: pulse output width. Range: t = 0~32,767ms.
3.
S2: pulse output cycle. Range: T = 1~32,767ms, S1 ≦ S2.
4.
S2 +1 and S2 +2 are system-defined parameters, please don’t use them.
5.
D: pulse output device: Y, M and S.
6.
When S1 ≦ 0, no pulse output will be performed. When S1 ≧ S2, the pulse output device
remains ON.
7.
S1 and S2 can be modified when GPWM instruction is being executed
Program Example:
Assume D0 = K1000, D2 = K2000. When X0 = ON, Y20 will output pulses as the following diagram.
When X0 = OFF, Y20 output will be OFF.
t

T
D2
Y20
t=1000ms
Output Y20
T=2000ms
Points to note:
1.
The instruction operates by the scan cycle; therefore the maximum error will be one PLC
scan cycle. S1, S2 and (S2 - S1) should be bigger than PLC scan cycle, otherwise malfunction
will occur during GPWM outputs.
2.
Please note that placing this instruction in a subroutine will cause inaccurate GPWM outputs

Explanations:
1.
There are 5,000 16-bit file registers. The register numbers range from K0 to K4999.
2.
The 32-bit instruction is not supported.
3.
If m, D, or n is not within the range, an operation error occurs, the instruction is not executed,
M1067 and M1068 is ON, and the error code in D1067 is H’0E1A.
4.
If no data is written into the file register, the default value which will be read from it is -1.

DVP-ES2/EX2/SS2 version 2.80 and above, DVP-SA2/SX2 version 2.40 and above are
supported. The instruction is not applicable to DVP-ES2-C.
6.
The file registers do not support M1101. If users want to read the data from the file register
when the PLC runs, they can use LD M1002 and MEMR to read the data.
Program Example:
1.
Use MEMR to read the data from the 100 file registers starting from the tenth file register to the
data registers starting from D2000.
2.
When X0 is ON, the instruction is executed. When X0 becomes OFF, the instruction is not
executed, and the data which is read previous is unchanged.

Explanations:
1.
There are 5,000 16-bit file registers. The register numbers range from K0 to K4999.
2.
The 32-bit instruction is not supported.
3.
If m, D, or n is not within the range, an operation error occurs, the instruction is not executed,
M1067 and M1068 is ON, and the error code in D1067 is H’0E1A.
4.
Owing to the fact that the file registers take flash ROM as the memories, 100 words at most
can be written into the file registers, and only when the conditional contact turns from OFF to
ON can the data be written into the file registers once. Note: The data only can be written into
the file registers 100,000 times. Please use them with care.

Rising-edge contact (LDP, ANDP, ORP) and falling-edge contact (LDF, ANDF, ORF) can not
be used as drive contact of MODRW (Function code H02, H03) instruction, otherwise the data
stored in the receiving registers will be incorrect.
9.
If rising-edge contacts (LDP, ANDP, ORP) or falling-edge contacts (LDF, ANDF, ORF) is used
before MODWR instruction, sending request flag M1122(COM2) / M1312(COM1) /
M1316(COM3) has to be executed as a requirement.
10.
MODRW instruction determines the COM port according to the communication request. The
COM port determination is made following the order: COM1ÆCOM3ÆCOM2. Therefore,
please insert every MODRW instruction right after the sending request instruction for avoiding
errors on the target location for data access.

Program Example 2: COM1(RS-232) / COM3(RS-485), Function Code H02
1.
Function code K2 (H02): read multiple bit devices. Up to 64 bits can be read.
2.
PLC1 connects to PLC2: (M1320 = OFF, ASCII mode), (M1320 = ON, RTU mode)
3.
For both ASCII and RTU modes, PLC COM1/COM3 only stores the received data in registers
starting from S, and will not store the data to be sent. The stored data can be transformed and
moved by using DTM instruction for applications of other purposes.
4.
Take the connection between PLC1 (PLC COM3) and PLC2(PLC COM1) for example, the
tables below explains the status when PLC1 reads Y0~Y17 of PLC2
z
If PLC1 applies COM1 for communication, the below program can be usable by
changing:
1. D1109→D1036: communication protocol
2. M1136→M1138: retain communication setting
3. D1252→D1249: Set value for data receiving timeout
4. M1320→M1139: ASCII/RTU mode selection
5. M1316→M1312: sending request

Operands:
S1: Target frequency for zero return
S2: JOG frequency for DOG
S3: input device for DOG
D:
Pulse output device
Explanations:
1.
S1 (zero return speed): max. 100kHz. S2 (JOG speed for DOG) has to be lower than S1. JOG
speed for DOG also refers to the start frequency.
2.
S3 and D operands have to be used as an input/output set according to the table below, i.e. when
S3 is specified as X4, D has to be specified as Y0; also when S3 is specified as X6, D has to be
specified as Y2.
3.
M1307 enables (ON) / disables (OFF) left limit switch of CH0 (Y0, Y1) and CH1 (Y2, Y3). M1307
has to be set up before the instruction executes. M1305 and M1306 can reverse the pulse output
direction on Y1 and Y3 and have to be set up before instruction executes. Associated left limit
switch for CH0 (Y0, Y1) is X5; associated left limit switch for CH1 (Y2, Y3) is X7. All functions,
input points and output points are arranged as follows:
Channel

4.
When D is specified as Y0, its direction signal output is Y1; when D is specified as Y2, its direction
signal output is Y3.
5.
When pulse output reaches zero point, pulse output execution completed flag M1029 (CH0),
M1102 (CH1) is ON and the register indicating current position is reset to 0.
6.
When DZRN instruction executes, external interrupt I400/I401(X4)) or I600/I601(X6) in program
will be disabled until DZRN instruction is completed. Also. If left limit switch (X5 / X7) is enabled
during instruction execution, external interrupt I500501(X5) or I700/I701(X7) will be disabled as
well.
7.
Zero point selection: the default position of zero point is on the left of DOG switch (the input point
On→Off) (as mode 1 shows). If the user needs to change the zero point to the right of DOG switch,
set ON M1106(CH0) or M1107(CH1) before DZRN instruction executes. (The function supports
ES2/EX2 series, V1.20 or above.)
8.
Start the pulse-clearing function of the output. When DOG leaves DOG switch and is going to stop,
it will output another pulse (the width of On is about 20ms). When the pulse is On→Off, there will
be a completed flag output. Please refer to state 4 for the timing diagram of this function. (The
function supports ES2/EX2 series, V1.20 or above.)
9.
When D1312 is not set to be 0, and M1308=Off, the function of seeking Z phase is started. When
D1312 is a positive value (the maximum value is 10), it indicates that the search for Z-phase signal
is toward the positive direction. When D1312 is a negative value (the minimum value is -10), it
indicates that the search for Z-phase signal is toward the negative direction. For example, if D1312
is k-2, it means that DOG stops immediately after DOG leaves DOG switch and searches in the
negative direction for second Z-phase signal (the fixed right-edge trigger) with JOG frequency.
Please refer to state 5 for the timing diagram of this function. (The function supports ES2/EX2
series of V1.20 or above, and SS2/SX2 series of V1.20 or above.)
10.
When D1312 is not set to be 0 and M1308=On, the function of outputting the designated number
of pulses is started. When Dd1312 is a positive value (the maximum value is 30000), it indicates
that the pulses are output in the positive direction. When D1312 is a negative value (the minimum
value is -30000), it indicates that the pulses are output in the negative direction. For example, if
D1312 is k-100, it means that DOG stops immediately after DOG leaves DOG switch and another
100 pulses will be output in the negative direction with JOG frequency. Please refer to state 6 for
the timing diagram of this function. (The function supports ES2/EX2 series of V1.40 or above, and
SS2/SX2 series of V1.20 or above.)

Operands:
S: Pulse output frequency
D1: Pulse output device (Y0, Y2)
D2: Direction signal output
Explanations:
1.
The instruction only supports the pulse output type: Pulse + Direction.
2.
S is the designated pulse output frequency. Available range: -100,000Hz ~ +100,000 Hz. “+/-”
signs indicate forward/reverse output direction. The frequency can be changed during pulse
output. However, if the specified output direction is diferent from the current output direction, the
instruction will stop for 1 scan cycle then restart with the changed frequency.
3.
D1 is the pulse output device. It can designate CH0(Y0) and CH1(Y2).
4.
D2 is the direction signal output device. It can designate CH0(Y1) and CH1(Y3).
5.
The operation of D2 corresponds to the “+” or “-“ of S. When S is “+”, D2 will be OFF; when S is “-“,
D2 will be ON.
6.
M1305 and M1306 can change the output direction of CH0/CH1 set in D2. When S is “-“, D2 will
be ON, however, if M1305/M1306 is set ON before instruction executes, D2 will be OFF during
execution of instruction.
7.
PLSV instruction does not support settings for ramp up or ramp down. If ramp up/down process is
required, please use API 67 RAMP instruction.
8.
If the drive contact turns off during pulse output process, pulse output will stop immediately.
Program Example:
When M10 = ON, Y0 will output pulses at 20kHz. Y1 = OFF indicates forward direction.

Operands:
S1: Number of pulses (relative positioning)
S2: Pulse output frequency
D1: Pulse output device
D2: Direction signal output
Explanations:
1.
The instruction only supports the pulse output type: Pulse + Direction.
2.
S1 is the number of pulses (relative positioning). Available range: -2,147,483,648 ~
+2,147,483,647. “+/-” signs indicate forward and reverse direction.
3.
S2 is the pulse output frequency. Available range: 6 ~ 100,000Hz.
4.
D1 is the pulse output device. It can designate CH0 (Y0) and CH1 (Y2).
5.
D2 is the direction signal output device. It can designate CH0 (Y1) and CH1 (Y3).
6.
The operation of D2 corresponds to the “+” or “-“ of S. When S is “+”, D2 will be OFF; when S is
“-“, D2 will be ON. D2 will not be OFF immediately after pulse output completion and will be
OFF when the drive contact is OFF.
7.
The set value in S1 is the relative position of
- current position (32-bit data) of CH0 (Y0, Y1) which is stored in D1031(high), D1030 (low)
- current position (32-bit data) of CH1 (Y2, Y3) which is stored in D1337(high), D1336 (low).
In reverse direction pulse output, value in (D1031, D1330) and (D1336, D1337) decreases.
8.
D1343 (D1353) is the ramp up/down time setting of CH0 (CH1). Available range: 20 ~
32,767ms. Default: 100ms. PLC will take the upper/lower bound value as the set value when
specified value exceeds the available range.
9.
D1340 (D1352) is start/end frequency setting of CH0 (CH1). Available range: 6 to 100,000Hz.
PLC will take the upper/lower bound value as the set value when specified value exceeds the
available range.
10.
M1305 and M1306 can change the output direction of CH0/CH1 set in D2. When S is “-“, D2 will
be ON, however, if M1305/M1306 is set ON before instruction executes, D2 will be OFF during
execution of instruction..

3. Instruction Set
11.
Ramp-down time of CH0 and CH1 can be particularly modified by using (M1534, D1348) and
(M1535, D1349). When M1534 / M1535 = ON, CH0 / CH1 ramp-down time is specified by
D1348 / D1349.
12.
If M1078 / M1104 = ON during instruction execution, Y0 / Y2 will pause immediately and
M1538 / M1540 = ON indicates the pause status. When M1078 / M1104 = OFF, M1538 /
M1540 = OFF, Y0 / Y2 will proceed to finish the remaining pulses.
13.
DRVI instruction supports Alignment Mark and Mask function. Please refer to the explanation
in API 59 PLSR instruction.
Program Example:
When M10= ON, 20,000 pulses (relative position) at 2kHz frequency will be generated from Y0. Y1=
OFF indicates positive direction.

Operands:
S1: Numbers of pulses (Absolute positioning)
device
S2: Pulse output frequency
D1: Pulse output
D2: Direction signal output
Explanations:
1.
The instruction only supports the pulse output type: Pulse + Direction.
2.
S1 is the number of pulses (Absolute positioning). Available range: -2,147,483,648 ~
+2,147,483,647. “+/-” signs indicate forward and reverse direction.
3.
S2 is the pulse output frequency. Available range: 6 ~ 100,000Hz.
4.
D1 is the pulse output device. It can designate CH0 (Y0) and CH1 (Y2).
5.
D2 is the direction signal output device. If Y output is designated, only CH0 (Y1) and CH1 (Y3)
are available.
6.
S1 is the target position for absolute positioning. The actual number of output pulses (S1 –
current position) will be calculated by PLC. When the result is positive, pulse output executes
forward operation, i.e. D2 = OFF; when the results is negative, pulse output executes reverse
operation, i.e. D2 = ON.
7.
The set value in S1 is the absolute position from zero point. The calculated actual number of
output pulses will be the relative position of
- current position (32-bit data) of CH0 (Y0, Y1) which is stored in D1031(high), D1030 (low)
- current position (32-bit data) of CH1 (Y2, Y3) which is stored in D1337(high), D1336 (low).
In reverse direction pulse output, value in (D1031, D1330) and (D1336, D1337) decreases.
8.
D1343 (D1353) is the ramp up/down time (between start frequency and pulse output
frequency) setting of CH0 (CH1). Available range: 20 ~ 32,767ms. Default: 100ms. PLC will
take 20ms as the set value when specified value is below 20ms or above 32,767ms.
9.
D1340 (D1352) is start/end frequency setting of CH0 (CH1). Available range: 6 ~ 32,767Hz.
PLC will take the start/end frequency as the pulse output frequency when pulse output
frequency S2 is smaller or equals the start/end frequency.
3-374
3. Instruction Set
10.
M1305 and M1306 can change the output direction of CH0/CH1 set in D2. When S is “-“, D2 will
be ON, however, if M1305/M1306 is set ON before instruction executes, D2 will be OFF during
execution of instruction..
11.
Ramp-down time of CH0 and CH1 can be particularly modified by using (M1534, D1348) and
(M1535, D1349). When M1534 / M1535 = ON, CH0 / CH1 ramp-down time is specified by
D1348 / D1349.
12.
If M1078 / M1104 = ON during instruction execution, Y0 / Y2 will pause immediately and
M1538 / M1540 = ON indicates the pause status. When M1078 / M1104 = OFF, M1538 /
M1540 = OFF, Y0 / Y2 will proceed to finish the remaining pulses.
13.
DRVA/DDRVA instructions do NOT support Alignment Mark and Mask function.
Program Example:
When M10 = ON, DRVA instruction executes absolute positioning on Y0 at target position 20000,
target frequency 2kHz. Y5 = OFF indicates positive direction.

S: Current time of RTC (occupies 3 consecutive devices)
D:
Comparison result (occupies 3 consecutive devices)
Explanations:
1.
TCMP instruction compares the time set in S1, S2, S3 with RTC current value in S and stores
the comparison result in D.
2.
S: “Hour” of current time of RTC. Content: K0~K23. S +1: “Minute” of current time of RTC.
Content: K0~K59. S +2: “Second” of current time of RTC. Content: K0~K59.
3.
Usually the time of RTC in S is read by TRD instruction first then compared by TCMP
instruction. If operand S exceeds the available range, operation error occurs and M1067 = ON,
M1068 = ON. D1067 stores the error code 0E1A (HEX).
Program Example:
1.
When X0 = ON, the instruction executes and the RTC current time in D20~D22 is compared
with the set value 12:20:45. Comparison result is indicated by M10~M12. When X0 goes from
ON→OFF, the instruction is disabled however the ON/OFF status of M10~M12 remains.

TZCP instruction compares current RTC time in S with the range set in S1~ S2 and the
comparison result is stored in D.
2.
S1, S1 +1, S1 +2: The “hour”, “minute” and “second” of the lower bound value for comparison.

4.
S, S +1, S +2: The “hour”, “minute” and “second” of the current time of RTC.
5.
Usually the time of RTC in S is read by TRD instruction first then compared by TZMP
instruction. If operand S, S1, S2 exceed the available range, operation error occurs and M1067
= ON, M1068 = ON. D1067 stores the error code 0E1A (HEX).
6.
If S < S1 and S < S2, D is ON. When S > S1 and S > S2, D+2 is ON. For other conditions, D + 1
will be ON. (Lower bound S1 should be less than upper bound S2.)
Program Example:
When X0 = ON, TZCP instruction executes and M10~M12 will be ON to indicate the comparison
results. When X0 = OFF, the instruction is disabled but the ON/OFF status of M10~M12 remains.

3.
If the addition result is larger than 24 hours, the carry flag M1022 will be ON and the value in D
will be the result of “sum minuses 24 hours”.
4.
If the sum equals 0 (00:00:00), Zero flag M1020 will be ON.
Program Example:
When X0 = ON, TADD instruction executes and the time value in D0~D2 is added with the time

= ON. D1067 stores the error code 0E1A (HEX).
3.
If the subtraction result is a negative value (less than 0), Borrow flag M1020 = ON and the
value in D will be the result of “the negative value pluses 24 hours”.
4.
If the subtraction result (remainder) equals 0 (00:00:00), Zero flag M1020 will be ON.
5.
Besides using TRD instruction, MOV instruction can also be used to move the RTC value to
D1315 (Hour), D1314 (Minute), D1313 (Second) for reading the current time of RTC..
Program Example:
When X0 = ON, TSUB instruction executes and the time value in D0~D2 is subtracted by the time
value in D10~D12. The subtraction result is stored in D20~D22.

Operand:
D: Current time of RTC (occupies 7 consecutive devices)
Explanations:
1.
TRD instruction reads the 7 real-time data of RTC (year (A.D.), day(Mon.Sun.), month, day,
hour, minute, second from D1319~D1313 and stores the read data in registers specified by D.
2.
Only when power is on can RTCs of SS2 series perform the fuction of timing. The RTC data
registers D1319~D1313 are latched. When power is resumed, the RTC will resume the stored
time value before power down. Therefore, we suggest users modify the RTC value every time
when power is ON.
3.
RTCs of SA2/SE V1.0 及 ES2/EX2/SX2 V2.0 series can still operate for one or two weeks after
the power is off (they vary with the ambient temperature). Therefore, if the machine has not
operated since one or two weeks ago, please reset RTC.
4.
D1319 only stores the 2-digit year in A.D. If 4-digit year data is required, please refer to Points
to note below.
5.
For relative flags and registers please refer to Points to note.
Program Example:
When X0 = ON, TRD instruction reads the current time of RTC to the specified register D0~D6.

Operands:
S1: Source device 1
S2: Bits to be masked (OFF)
D: D =( S1 & S2) | ( D & ~ S2)
Explanations:
1.
The instruction conducts logical AND operation between S1 and S2 first, logical AND operation
between D and ~S2 secondly, and combines the 1st and 2nd results in D by logical OR
operation.
2.
Rule of Logical AND operation: 0 AND 1 = 0, 1 AND 0 = 0, 0 AND 0 = 0, 1 AND 1 = 1
3.
Rule of Logical OR operation: 0 OR 1= 1, 1 OR 0 = 1, 0 OR 0 = 0, 1 OR 1 = 1.
Program Example 1 :
When X0 = ON, MVM instruction conducts logical AND operation between 16-bit register D0 and
H’FF00 first, logical AND operation between D4 and H’00FF secondly, and combines the 1st and 2nd
results in D4 by logical OR operation.

Operands:
S: Set-point value for driving the output device (Unit: hour)
D1: Current time being measured
D2: Output device
Explanations:
1.
HOUR instruction drives the output device D2 when the measured current time D1 reaches the
set-point value in S.
2.
Range of S: K1~K32,767; unit: hour. Range of D1 in 16-bit instruction: K0~K32,767. Range of
D1 +1 (current time less than an hour): K0 ~K3,599; unit: second.
3.
When the ON-time of the drive contact reaches the set-point value, output device will be ON.
The instruction can be applied for controlling the working hours of machine or conducting
preventive maintenance.
4.
After output device is ON, the current time will still be measured in D1.
5.
In 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.
6.
In 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.
7.
If operand S uses device F, only 16-bit instruction is available.
8.
HOUR instruction can be used for four times in the program.
Program Example 1:
In 16-bit instruction, when X0 = ON, Y20 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). D1 will
record the current time less than an hour (0 ~ 3,599; unit: second)..

2.
Available range of S:
16-bit instruction: 0~32,767
32-bit instruction: 0~2,147,483,647
3.
If operand S exceeds the available range, operation error occurs and M1067 = ON, M1068 =
ON. D1067 stores the error code 0E1A (HEX)
4.
If operands S and D use device F, only 16-bit instruction is applicable.

Explanations:
1.
GBIN instruction converts the Gray Code in S to BIN value and stores the converted result in
specified register D.
2.
This instruction can be used to read the value from an absolute position type encoder
(generally a Gray Code encoder) which is connected to the PLC inputs. The Gray code is
converted to BIN value and stored in the specified register.
3.
Available range of S:
16-bit instruction ：0~32,767
32-bit instruction ：0~2,147,483,647
4.
If operand S exceeds the available range, operation error occurs and the instruction is
disabled.
5.
If operands S and D use device F, only 16-bit instruction is applicable.
Program Example:
When X20 = ON, the Gray Code value in the absolute position type encoder connected to X0~X17
inputs is converted to BIN value and stored in D10.

Operands:
S1: Floating point summand
S2: Floating point addend

Explanations:
1. ADDR instruction adds the floating point summand S1 with floating point addend S2 and stores
the operation result in D.
2. In ADDR instruction, floating point values can be directly entered into S1 and S2.
3. In DADDR instruction, floating point values (e.g. F1.2) can be either entered directly into S1
and S2 or stored in data registers for operation.
4. When S1 and S2 is specified as data registers, the function of DADDR instruction is the same
as API 120 EADD instruction.
5. S1 and S2 can designate the same register. In this case, if the instruction is specified as
“continuous execution instruction” (generally DADDRP instruction) and the drive contact is ON,
the register will be added once in every scan.
6. Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)
If absolute value of the result exceeds max floating point value, carry flag M1022 = ON.
If absolute value of the result is less than min. floating point value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON
Program Example 1:
When X0 = ON, add floating point number F1.200E+0 (Input F1.2, and scientific notation
F1.200E+0 will be displayed on ladder diagram. Users can set monitoring data format as float on
the function View) with F2.200E+0 and store the obtained result F3.400E+0 in register D10 and

2. In SUBR instruction, floating point values can be directly entered into S1 and S2..
3. In DSUBR instruction, floating point values (e.g. F1.2) can be either entered directly into S1

4. When S1 and S2 is specified as data registers, the function of DSUBR instruction is the same
as API 121 ESUB instruction.
5. S1 and S2 can designate the same register. In this case, if the instruction is specified as
“continuous execution instruction” (generally DSUBRP instruction) and the drive contact is ON,
the register will be subtracted once in every scan.
6. Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)
If absolute value of the result exceeds max floating point value, carry flag M1022 = ON.

Operands:
S1: Floating point multiplicand
S2: Floating point multiplicator
D: Product
Explanations:
1. MULR instruction multiplies S1 with S2 and stores the operation result in D.
2. In MULR instruction, floating point values can be directly entered into S1 and S2.
3. In DMULR instruction, floating point values (e.g. F1.2) can be either entered directly into S1
and S2 or stored in data registers for operation.
4. When S1 and S2 is specified as data registers, the function of DMULR instruction is the same
as API 122 EMUL instruction.
5. S1 and S2 can designate the same register. In this case, if the instruction is specified as
“continuous execution instruction” (generally DMULRP instruction) and the drive contact is ON,
the register will be multiplied once in every scan
6. Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)
If absolute value of the result exceeds max floating point value, carry flag M1022 = ON.
If absolute value of the result is less than min. floating point value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example 1:
When X0= ON, multiply floating point number F1.200E+0 (Input F1.2, and scientific notation
F1.200E+0 will be displayed on ladder diagram. Users can set monitoring data format as float on
the function View) with F2.200E+0 and store the obtained result F2.640E+0 in register D10 and
D11.

Program example 2:

Operands:
S1: Floating point n dividend

D: Quotient
Explanations:
1. DIVR instruction divides S1 by S2 and stores the operation result in D
2. In DIVR instruction, floating point values can be directly entered into S1 and S2.
3. In DDIVR instruction, floating point values (e.g. F1.2) can be either entered directly into S1 and
S2 or stored in data registers for operation.
4. When S1 and S2 is specified as data registers, the function of DDIVR instruction is the same as
API 123 EDIV instruction.
5. If S2 = 0, operation error occurs and M1067 = ON, M1068 = ON. D1067 stores the error code
0E19 (HEX).
6. Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)
If absolute value of the result exceeds max floating point value, carry flag M1022 = ON.
If absolute value of the result is less than min. floating point value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program example 1:
When X0 = ON, divide floating point number F1.200E+0 (Input F1.2, and scientific notation
F1.200E+0 will be displayed on ladder diagram. Users can set monitoring data format as float on

1.
MAND instruction performs matrix AND operation between matrix source device 1 and 2 with
matrix length n and stores the operation result in D.
2.
Rule of AND operation: the result is 1 only when both two bits are 1; otherwise the result is 0.
3.
If operands S1, S2, D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
Program Example:
When X0 = ON, MAND performs matrix AND operation between 16-bit registers D0~D2 and 16-bit

Points to note:
1.
A matrix consists of more than 1 consecutive 16-bit registers. The number of registers is
indicated as the matrix length (n). A matrix contains 16 × n bits (points) and the matrix
instructions conduct bit operation, i.e. operation is performed bit by bit.
2.
Matrix instructions designate a single bit of the 16 × n bits (b0 ~ b16n-1) for operation. The bits
in matrix are not operated as value operation.
3.
The matrix instructions process the moving, copying, comparing and searching of
one-to-many or many-to-many matrix operation, which are a very handy and important
application instructions.
4.
The matrix operation requires a 16-bit register for designating a bit among the 16n bits in the
matrix. The register is the Pointer (Pr) of the matrix, designated by the user in the instruction.
The valid range of Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix.
5.
The bit number decreases from left to right (see the figure below). With the bit number, matrix
operation such as bit shift left, bit shift right, bit rotation can be performed and identified.

6.
The matrix width (C) is fixed as 16 bits.
7.
Pr: matrix pointer. E.g. if Pr is 15, the designated bit is b15.
8.
Matrix length (R) is n: n = 1 ~ 256.
Example: This matrix is composed of D0, n = 3; D0 = HAAAA, D1 = H5555, D2 = HAAFF

D: Operation result
n: Matrix length (n = K1~K256)
Explanations:
1.
MOR instruction performs matrix OR operation between matrix source device 1 and 2 with
matrix length n and stores the operation result in D.
2.
Rule of matrix OR operation: the result is 1 if either of the two bits is 1. The result is 0 only
when both two bits are 0.
3.
If operands S1, S2, D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
Program Example:
When X0 = ON, MOR performs matrix OR operation between 16-bit registers D0~D2 and 16-bit
registers D10~D12. The operation result is then stored in 16-bit registers D20~D22.

Operands:
S1: Matrix source device 1
S2: Matrix source device 2
n: Matrix length (K1~K256)
D: Pointer Pr; comparison result (bit number)
Explanations:
1.
MCMP instruction compares each bit between matrix S1 and matrix S2 and stores the bit
number of the comparison result in D. The comparison starts from the next bit of the pointer.
2.
The matrix comparison flag (M1088) decides to compare between equivalent values (M1088
= ON) or different values (M1088 = OFF). When the comparison is completed, it will stop
immediately and M1091= ON to indicate that matched result is found. When the comparison
progresses to the last bit, M1089 = ON to indicate that the comparison has come to the end of
the matrix and the number of the last bit will be stored in D. In next scan cycle, comparison
starts again from the first bit (bit 0), at the same time M1090 = ON to indicate the start of the
comparison. When D (Pr) exceeds the valid range, M1092 = ON to indicate pointer error, and
the instruction will be disabled.
3.
The matrix operation requires a 16-bit register for designating a bit among the 16n bits in the
matrix. The register is the Pointer (Pr) of the matrix, designated by the user in the instruction.
The valid range of Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix. The value of
pointer should not be modified during the execution of matrix instructions so as to prevent
execution errors.
4.
When M1089 and M1091 take place at the same time, both flags will ON..
5.
If operands S1, S2, or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
Program Example:
When X0 goes from OFF to ON with M1090 = OFF (comparison starts from Pr), the search will
start from the bit marked with “*” (current Pr value +1) for the bits with different status (M1088 =
OFF).
Assume pointer D20 = 2, the following four results (n, o, p, q) can be obtained when X0 goes
from OFF→ON for four times.
n D20 = 5, M1091 = ON (matched result found), M1089 = OFF

Operands:
S: Matrix source device
n: Matrix length (K1~K256).
D: Pointer Pr (bit number)
Explanations:
1.
MBRD instruction reads the bit status of the matrix. When MBRD executes, the status of
M1094 (Matrix pointer clear flag) will be checked first. If M1094 = ON, Pr value in D will be
cleared and the instruction reads from the first bit. The bit status is read out and mapped to
M1095 (Carry flag for matrix operation). After a bit is read, MBRD checks the status of
M1093 (Matrix pointer increasing flag). If M1093 = ON, MBRD instruction will proceed to read
the next bit, i.e. Pr value plus 1. When MBRD proceeds to the last bit, M1089 = ON,
indicating the end of the Matrix, and D records the last bit number. After this, MBRD
instruction stops.
2.
The Pointer (Pr) of the matrix is designated by the user in the instruction. The valid range of
Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix. If the Pr value exceeds the valid
range, M1092 = ON and the instruction will be disabled.
3.
If operands S or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
Program Example:
1.
When X0 goes from OFF→ON with M1094 = ON (Clear Pr value) and M1093 = ON (Increase
Pr value), the reading will start from the first bit and Pr value increases 1 after a bit is read.
2.
Assume present value of pointer D20 = 45, the following 3 results (n, o, p) can be obtained
when X0 is executed from OFF→ON for 3 times.
n D20 = 45, M1095 = OFF, M1089 = OFF
o D20 = 46, M1095 = ON (bit status is ON), M1089 = OFF.
p D20 = 47, M1095 = OFF, M1089 = ON. (reading proceeds to the last bit)

D: Pointer Pr (bit number).
Explanations:
1.
MBWR instruction writes the bit status of the matrix. When MBWR executes, the status of
M1094 (Matrix pointer clear flag) will be checked first. If M1094 = ON, Pr value in D will be
cleared and the instruction writes from the first bit. The bit status of M1096 (Borrow flag for
matrix operation) is written into the first bit of the matrix. After a bit is written, MBWR checks
the status of M1093 (Matrix pointer increasing flag). If M1093 = ON, MBWR instruction will
proceed to write the next bit, i.e. Pr value plus 1. When MBWR proceeds to the last bit,
M1089 = ON, indicating the end of the Matrix, and D records the last bit number. After this,
MBWR instruction stops.
2.
The Pointer (Pr) of the matrix is designated by the user in the instruction. The valid range of
Pr is 0 ~ 16n -1, corresponding to b0 ~ b16n-1 in the matrix. If the Pr value exceeds the valid
range, M1092 = ON and the instruction will be disabled.
3.
If operands S or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
Program Example:
1.
When X0 goes from OFF→ON with M1094 = OFF (Starts from Pr value) and M1093 = ON
(Increase Pr value), the writing will start from the bit number in Pr and Pr value increases 1
after a bit is written.

Explanations:
1.
MBS instruction shifts the bits in the matrix to the left or the right. M1097 = OFF, bits shift to
the left, M1097 = ON, bits shift to the right. The empty bit (left shift: b0; right shift: b16n-1)
after every bit is shifted once will be filled with the value of M1096 (Borrow flag for matrix
operation). The bit which is shifted out of the matrix (left shift: b16n-1; right shift: b0) will be
sent to M1095 (Carry flag for matrix operation) and operation result is stored in D.
2.
The pulse execution instruction (MBSP) is generally adopted.
3.
If operands S or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable
4.
Associated flags:
M1095: Carry flag for matrix rotation/shift/output

Explanations:
1.
MBR instruction rotates the bits in the matrix to the left or the right. M1097 = OFF, bits rotate
to the left, M1097 = ON, bits rotate to the right. The empty bit (left rotate: b0; right rotate:
b16n-1) after rotation performed once will be filled with the bit which is rotated out of the
matrix (left rotate: b16n-1; right rotate: b0) and the operation result is stored in D. In addition,
the bit which is rotated out of the matrix will also be moved to M1095 (Carry flag for matrix
operation).
2.
The pulse execution instruction MBRP is generally adopted.
3.
If operands S or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
4.
Associated flags:
M1095: Carry flag for matrix rotation/shift/output.
M1097: Direction flag for matrix rotation/shift
Program Example 1:
When X0 = ON, M1097 = OFF, indicating a left matrix rotation is performed. The 16-bit registers
D0 ~ D2 will perform a left matrix rotation and the result will be stored in the matrix of the 16-bit

Explanations:
1.
MBC instruction counts the number of bit 1 or bit 0 in the matrix with matrix length n and
stores the counted number in D.
2.
If operands S or D use KnX, KnY, KnM, KnS format, only n = 4 is applicable.
3.
When M1098 = ON, MBC instruction counts the number of bit 1. M1098 = OFF, MBC counts
the number of bit 0. If bits counting result is 0, M1099 = ON
4.
Associated flags:
M1098: Counting the number of bits which are “1” or “0”
M1099: ON when the bits counting result is “0”..
Program Example:
When X0 = ON with M1098 = ON, MBC instruction counts the number of bit 1 in D0~D2 and store
the counted number in D10. When X0 = ON with M1098 = OFF, the instruction counts the number
of bit 0 in D0~D2 and store the counted number in D10.

Operands:
S1: Number of output pulses on X axis S2: Number of output pulses on Y axis
point output frequency D: Pulse output device
S: Max. point to
Explanations:
1.
For ES2/EX2 models, only V1.20 or above supports the function.
2.
The instruction only supports the pulse output type: Pulse / Direction.
3.
S1 and S2 specify the number of output pulses (relative positioning) on X axis (Y0) and Y axis
(Y2). Range: -2,147,483,648 ~ +2,147,483,647 (The “+/-“ sign indicates the forward/backward
direction). In forward direction, the present value of pulse output on CH0 (D1031 High, D1030
low), CH1 (D1337 high, D1336 low) increases. In reverse direction pulse output, value in
(D1031, D1330) and (D1336, D1337) decreases.
4.
S: If the max output frequency is smaller than 100Hz, the output will be operated at 100Hz. If
the setting is bigger than 100kHz, the output will be operated at 100kHz
5.
D can designate Y0 only.
Y0 is the pulse output point of X axis;
Y1 is the direction signal output of X axis.(OFF: positive; ON: negative)
Y2 is the pulse output point of Y axis;
Y3 is the direction signal output of Y axis (OFF: positive; ON: negative)
When the pulse output is completed, the direction output signal will not be OFF unless the
drive contact is OFF.
6.
D1340 is start/end frequency setting of X/Y axis. When the set value is smaller than 6Hz, PLC
will take 6 Hz as the set value. D1343 is the ramp up/down time setting of X/Y axis. If the ramp
up/down time is shorter than 20ms, the frequency will be operated at 20ms. Default: 100ms.
7.
When PPMR instruction is enabled, the start frequency and acceleration/deceleration time in Y
axis will be the same as the settings in X axis. In addition, setting ramp-down time individually
by D1348/D1349 is not recommended because it could lead to the inconsistency between X
and Y axes. Also, the flags of “pulse output pause (immediate)” are not applicable. To stop the
pulse output, simply turn off the drive contact of this instruction.
3-424
3. Instruction Set
8.
For pulse output with ramp-up/down section, if only 1 axis is specified with pulse output
number, i.e. another axis is 0, the pulse output will only be performed on the axis with output
pulse number. However, if the output pulse number is less than 20 in any of the 2 axes, the
ramp-up/down section will be disabled and pulse output will be executed with the frequency
not higher than 3kHz.
9.
There is no limitation on the number of times for using the instruction. However, assume CH0
or CH1 pulse output is in use, the X/Y axis synchronized output will not be performed.
10. M1029 will be ON when 2-axis synchronized pulse output is completed.
Program Example:
1. Draw a rhombus as the figure below.
Y
(0, 0)
(-2700 0,-27 000)
X
(270 00,-27 000)
(0, -5 5000)
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 registers
(D200, D202), (D204, D206), (D208, D210), (D212, D214).
b) Design instructions as follows.
c) RUN the PLC. Set ON M0 to start the 2-axis line drawing.

S2: Number of output pulses of Y axis
S: Parameter
D: Pulse output device
Explanations:
1. For ES2/EX2 models, only V1.20 or above supports the function.
2. The instruction only supports the pulse output type: Pulse / Direction.
3. S1 and S2 specify the number of output pulses (relative positioning) on X axis (Y0) and Y axis
(Y2). Range: -2,147,483,648 ~ +2,147,483,647 (The “+/-“ sign indicates the forward/backward
direction). In forward direction, the present value of pulse output on CH0 (D1031 High, D1030
low), CH1 (D1337 high, D1336 low) increases. In reverse direction pulse output, value in
(D1031, D1330) and (D1336, D1337) decreases.
4. The low word of S (settings of direction and resolution): K0 refers to clockwise 20-segment
output; K1 refers to counterclockwise 20-segment output; A 90° arc can be drawn (see figure 1
and 2).
5. The high word of S (settings of motion time, unit: 0.1sec): Setting range: K2 ~ K200 (0.2 sec. ~
20 secs.) This instruction is restricted by the maximum pulse output frequency; therefore when
the set time is faster than the actual output time, the set time will be automatically modified.

6. Draw four 90° arcs as the figure below.
When the direction signal is ON, the direction is positive(QI, QIV). When the direction signal is
OFF, the direction is negative(QII, QIII). When S is set as K0, the arcs will be clockwise (see
figure 3). When S is set as K, the arcs will be counterclockwise (see figure 4).

8. The settings of motion time in the high word of S shall not be faster than the fastest suggested
time. If the motion time is not specified, PLC will use the fastest suggested motion time as the
setting. Refer to the table below.

9. D can designate Y0 only.
Y0 is the pulse output point of X axis;
Y1 is the direction signal output of X axis.(OFF: positive; ON: negative)
Y2 is the pulse output point of Y axis;
Y3 is the direction signal output of Y axis (OFF: positive; ON: negative)
When the pulse output is completed, the direction output signal will not be OFF unless the drive
contact is OFF
10. When the 2-axis interpolation is being executed in 20 segments, it takes approximately 2ms for
the initialization of this instruction. If only 1 axis is specified with pulse output number (with
ramp-up/down section), i.e. another axis is 0, PLC will only execute single-axis positioning
according to the specified motion time. If one of the two axes is specified with the pulse number
less than 500, PLC will execute 2-axis linear interpolation automatically. However, when either
axis is specified for pulse number over 10,000,000, the instruction will not work.
11. If the number of pulses which exceeds the above range is required, the user may adjust the
gear ratio of the servo for obtaining the desired results.
12. Every time when the instruction is executed, only one 90° arc can be drawn. It is not necessary
3-430
3. Instruction Set
that the arc has to be a 90° 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 ramp-up/down time.
14. There is no limitation on the number of times for using the instruction. However, assume CH0 or
CH1 output is in use, the X/Y axis synchronized output will not be performed
Program Example 1:
1. Draw an ellipse as the figure below.
Y
( 16 00 ,22 00 )
X
( 0,0 )
( 32 00 ,0)
(1 6 00 ,-2 20 0)
2. Steps:
a) Set the four coordinates (0,0), (1600, 2200), (3200, 0), (1600, -2200) (as the figure above).
Calculate the relative coordinates of the four points and obtain (1600, 2200), (1600, -2200),
(-1600, -2200), and (-1600, 2200). Place them in the 32-bit registers (D200, D202), (D204,
D206), (D208, D210), (D212, D214).
b) Select “draw clockwise arc” and default “motion time” (S = D100 = K0).
c) RUN the PLC. Set ON M0 to start the drawing of the ellipse.

(Y2). Range: -2,147,483,648 ~ +2,147,483,647. When S1 and S2 are bigger than PV of pulse
output in CH0 (D1031 High, D1030 low) / CH1 (D1337 high, D1336 low), pulse output will
operate in positive direction and the direction signal output Y1, Y3 will be OFF. When S1 and
S2 are smaller than PV of pulse output, pulse output will operate in negative direction and the
direction signal output Y1, Y3 will be ON.

Operands:
S1: Source start device
S2: Number of segments
D: Pulse output device
Explanations:
1. S1 specifies the output frequency and the number of pulses according to the number of
segments set by S2. Each segment occupies consecutive 4 registers, i.e. (S1+0), (S1+1), (S1+2)
and (S1+3). (S1+0) and (S1+1) stores the output frequency; (S1+2) and (S1+3) stores the
number of output pulses.
2. Available output frequency for S1 : 6Hz~100,000Hz.
3. S2 + 0: total number of segments (range: 1 ~ 40). S2 + 1: The No. of current executing
segment. The number in S2 + 1 will be updated when the PLC scan reaches this instruction.
4. D can only be designated with output devices Y0 and Y2, i.e. only pulse output is supported.
Users need to apply other instructions if a control on direction signal output is required.
5. This instruction does not offer ramp up/down function. Therefore, when the instruction is
disabled, the output pulses will stop immediately.
6. There is no limitation on the times of using this instruction, however during each scan cycle,
Y0 and Y2 can be driven by one instruction at a time.
7. When the instruction is being executed, changes to the instruction parameter will be invalid.
8. Cyclic output can be performed on this instruction by driving ON M1262.
Program Example:
1. When X0 = ON, pulse output will be operated according to the set frequency and number of
pulses in every segment.
2. Format of the table:
S2 = D300, number of
segments (D300 = K40)

a) When S1 designates input points X and the pulse output reaches the target number of
feedbacks in S2, the output will continue to operate by the frequency of the last shift (end
frequency) until interrupts occur on input points X.
b) When S1 designates high speed counters and the pulse output reaches the target
number of feedbacks in S2, the output will continue to operate by the frequency of the
last shift (end frequency) until the feedback pulses reaches the target number.
c) S1 can be a high speed counter C or an input point X with external interrupt. If S1 is C,
DCNT instruction should be executed in advance to enable the high-speed counting
function, and EI instruction with I0x0 should be enabled for external interrupts. If S1 is X,
EI instruction with I0x0 should be enabled for external interrupts.
d) If S1 is specifed with counters, DHSCS instruction has to be programmed in user
program. Please refer to Program example 2 for details.
2. Range of S2: -2,147,483,648 ~ +2,147,483,647 (+ / - indicates the positive / negative rotation
direction). the present value of pulse output in CH0 (Y0, Y1) and CH1 (Y2, Y3) increases in
positive direction and decreases in negative direction. Registers storing present value of
pulse output: CH0(D1031 High, 1030 Low), CH1(D1337 High, D1336 Low)
3. If S3 is lower than 6Hz, the output will operate at 6Hz; if S3 is higher than 100kHz, the output
will operate at 100kHz.

D V P - E S 2 / E X 2 / S S 2 / S A2 / S X 2 O p e r a t i o n M a n u a l - P r o g r a m m i n g
4. D can only designate Y0 (Direction signal output: Y1) or Y2 (Direction signal output: Y3). The
direction signal output will be OFF only when the drive contact of the instruction is OFF, i.e.
completion of pulse output will not reset Y1 or Y3.
5. D1340 and D1352 stores the start/end frequencies of CH0 and CH1. Min. 6Hz, default:
100Hz.
6. D1343 and D1353 stores the ramp up/down time of CH0 and CH1. If the ramp up/down time
is shorter than 20ms, PLC will operate in 20ms. Dafault: 100ms.
7. Ramp-down time of CH0 and CH1 can be particularlily specified by the setting of (M1534,
D1348) and (M1535, D1349). When M1534 / M1535 is ON, ramp-down time of CH0 and CH1
is set by D1348 and D1349.
8. D1131 and D1132 are the output/input ratio(%) of the close loop control in CH0 and CH1. K1
refers to 1 output pulse out of 100 feedback pulses; K200 refers to 200 output pulses out of
the 100 feedback pulses. In general percentage equation, the value set in D1131 and D1132
represents numerators (output pulses, available range: K1 ~ K10,000) and the denominator
(the input feedbacks) is fixed as K100 (System defined).
9. M1305 and M1306 can reverse the direction of CH0, CH1 pulse output. For example, when
direction signal output (Y1/Y3) is OFF, pulse output will operate in positive direction. If
M1305/M1306 is set ON before the execution of this instruction, the pulse output will be
reversed as negative output direction.
10. When S1 designates input points X with interrupt pointers, D1244 / D1255 can be applied for
setting the idle time as limited pulse number, in case the interrupt is not properly triggered.
11. DCLLM instruction supports Alignment Mark and Mask function. Please refer to PLSR
instruction for details.

feedback pulses or external interruption signals.

3. Principles for adjusting the completion time of positioning:
a) The completion time of positioning refers to the total time of “ramp up + high speed +
ramp down + idle” (see the figure above). When percentage value (D1131/D1132) is
modified, the total number of output pulses will be increased or decreased as well as the
completion time.
b) When S1 designates input points X with interrupt pointers, D1244 / D1255 can be
applied for setting the idle time as limited pulse number, in case the interrupt is not
properly triggered.Users 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 idle 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 (target
number of feedbacks x percentage value / 100), users can improve the situation by
adjusting the percentage value, ramp-up/ramp-down time or target frequency.
Program Example1: Immediate stop high-speed pulse output by external interrupt
1. Adopt X4 as the input for external interrupt and I401 (rising-edge trigger) as the interrupt
pointer. Set target number of feedbacks = 50,000; target frequency = 100kHz; pulse output
device: Y0, Y1 (CH0); start/end frequency (D1340) = 100Hz; ramp-up time (D1343) = 100ms;
ramp-down time (D1348) = 100ms; percentage value (D1131) = 100; present value of output
pulses (D1030, D1031) = 0.

Operands:
S1: Target frequency of output
frequency
S2: Target number of pulses
S3: Gap time and gap
D: Pulse output device (Y0, Y2)
Explanations:
1.
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.
2.
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, however, if
the output direction is not specified in D1220/D1221, PLC will take this value as a positive
value. When target number of pulses are specified with 0, PLC will perform continuous
output.
3.
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: 1Hz ~ 32767Hz; set range for S3+0: 1ms ~ 80ms. If set value exceeds the available
range, PLC will take the upper or lower bound value.
4.
D pulse output device supports only Y0 and Y2. If Y1 and Y3 is required for output direction
control, D1220 or D1221 has tobe set as K1(Pulse/Dir).
5.
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 (Y0: M1538, Y2:
M1540). 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.

D: Pulse output
device (Y0, Y2)
Explanations:
1.
Max frequency for S1: 100kHz. When ICF instruction executes, frequecy changing will start
immediately with ramp-up/down process.
2.
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.
3.
If ICF instruction is used with DPLSY instruction, operand S2 is invalid.
4.
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.
5.
D pulse output device supports only Y0 and Y2.
6.
The instruction is suggested to be applied in interrupt subroutines for obtaining the better
response time and eexecution results
7.
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.

2.
If users change the target frequency by applying DICF instruction in insterupt subroutines, the

(execution time of DICF instruction).
The timing diagram is as below:

Program Example:
1. When M0 = ON, pulse output ramps up to 100kHz. Total shifts: 100, Gap frequency: 1000Hz,
Gap time: 10ms. 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.

SCAL instruction performs a proportional calculation according to the internal slope equation.
2.
Operation equation in the instruction: D = (S1 × S2) ÷ 1000 + S3
3.
Users have to obtain S2 and S3 (decimals are rounded up into 16-bit integers) by using the
slope and offset equations below.
Slope equation: S2 = [(max. destination value – min. destination value) ÷ (max. source value –
min. source value)] × 1,000
Offset equation: S3 = min. destination value – min. source value × S2 ÷ 1,000

This instruction is applicable for known slope and offset. If slope and offset are unknown,
please use SCLP instruction for the calculation.
2.
S2 has to be within the range -32,768 ~ 32,767. If S2 exceeds the applicable range, use SCLP
instruction instead.
3.
When adopting the slope equation, the max source value must be larger than min source
value, but the max destination value does not need to be larger than min destination value.
4.
If D > 32,767, D will be set as 32,767. If D < -32,768, D will be set as -32,768.

6.
Substitute the above parameters into y = kx + b and the operation instruction can be obtained.
y = kx + b = D = k S1 + b = slope × S1 + offset = slope × S1 + min. destination value – min.
source value × slope = slope × (S1 – min. source value) + min. destination value = (S1 – min.
source value) × (max. destination value – min. destination value) ÷ (max. source value – min.
source value) + min. destination value
7.
If S1 > max. source value, S1 will be set as max. source value. If S1 < min. source value, S1 will
be set as min. source value. When the source value and parameters are set, the following

instruction executes and the result of proportional calculation will be stored in D10.
2.
Equation: D10 = [(500 – 200) × (500 – 30)] ÷ (3000 – 200) + 30 = 80.35. Rounding off the

n: Data length (n = 1~16)
D: Destination device
Explanations:
1.
S1 and S2 can be T/C/D devices, for C devices only 16-bit devices are applicable (C0~C199).
2.
The value in the high 16 bits of n used in the 32-bit instruction is an invalid value.
3.
The value in the low 8 bits of n indicates the data length. For the 16-bit instruction, n is
between 1 and 16. For the 32-bit instruction, n is between 1 and 32. If n is less than 1, it is
count as 1. If n is larger than the maximum value, it is count as the maximum value.
4.
The 16-bit data is written into D. If the data length is less than 16 bits, the bit which does not
have a corresponding value is 0. For example, if n is K8, bit0~7 have corresponding values,
and bit8~15 are 0.
5.
The 32-bit instruction supports DVP-ES2/EX2 version 3.0 and above, DVP-SS2 version 2.8
and above, DVP-SA2 version 2.6 and above, DVP-SX2 version 2.4 and above, and DVP-SE.
6.
The value in the high 8 bits of n indicates the comparison condition. The relation between the
comparison conditions and the values are shown in the following table.

condition
7.
The example of setting n: If n used in the 16-bit instruction is H0108, eight pieces of data are
compared with eight pieces of data in terms of “larger than”. If n used in the 32-bit instruction is
H00000320, 32 pieces of data are compared with 32 pieces of data in terms of “less than”.
8.
If the setting value of the comparison condition exceeds the range, or the firmware version
does not support the comparison condition, the default comparion condition “equal to” is
executed. DVP-ES2/EX2 version 3.0and above, DVP-SS2 version 2.8 and above, DVP-SA2
version 2.6 and above, DVP-SX2 version 2.4 and above, and DVP-SE support the setting of
the comparison condition.

3. Instruction Set
9.
The 16-bit comparison values used in the 16-bit instruction are signed values. The comparison
values used in the 32-bit instruction are 32-bit signed values (M1162=OFF), or floating-point
numbers (M1162=ON).
10.
The 16-bit data or 32-bit data is written into D. If the data length is less than 16 bits or 32 bits,
the bit which does not have a corresponding value is 0. For example, if n is K8, bit0~7 have
corresponding values, and bit15~31 are 0.
11.
If the comparison result meets the comparison condition, the corresponding bit is 1. If the
comparison result does not meet the comparison condition, the corresponding bit is 0.
Program example:
When M0 = ON, compare the 16-bit value in D0~D7 with D20~D27 and store the results in D100.

Operands:
S: Source device of signal input (Only X0~X3 are available)
input speed information
S1: Sample time setting and the
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). When S specifies
X2, PLC only uses X2 input point and its associated high speed pulse output: Y2, in this case
Y3 is normal output point. When S specifies X3, PLC uses X2 (A phase) and X3 (B phase)
input points and their associated output: Y2 (Pulse) / Y3 (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) or (X2, X3) enabled by DCNT instruction, or high speed
pulse outputs (Y0, Y1) or (Y2, Y3) enabled by other high speed output instructions, CSFO
instruction will not be activated.
3.
If S specifies X1 / X3 with 2-phase 2 inputs, the counting mode is fixed as quadruple
frequency.
4.
During pulse output process of Y0 or Y2, special registers (D1031, D1330 / 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).
3-466
3. Instruction Set
6.
S1 +0 specifies the sampling times. The set value of sampling times is recommended to be
bigger when the input speed increases, so as to achieve a higher accuracy for speed catching.
For example, set S1 +0 as K1 for the speed range 1Hz~1KHz, K10 for the speed range
10Hz~10KHz, K100 for the speed range 100Hz~10KHz. 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, 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)

Communication Ports
DVP-ES2/EX2/SA2/SE/SX2 offers 3 communication ports (COM1~COM3), and DVP-SS2 offers 2
COM ports (COM1~COM2). COM ports of the above models support DELTA Q-link communication
format on HMI. Refresh rate of HMI can be increased by this function.
COM1: RS-232 communication port. COM1 can be used as master or slave and is the major COM port
for PLC programming. (It is not applicable to DVP-SE.)
COM2: RS-485 communication port. COM2 can be used as master or slave.
COM3 (ES2/EX2/SA2/SE): RS-485 communication port. COM3 can be used as master or slave. (For
DVP-ES2-C, COM3 is the CANopen port.)
COM3 (SX2): Conversion from the USB port to RS-232 port. COM3 can be used as slave only.
The 3 COM ports on the models mentioned above support Modbus ASCII or RTU communication
format.
USB (COM1) (SE): USB communication port. It only can be used as a slave. The communication
mode and format can not be modified.

4.2.1 ADR (Communication Address)
Valid communication addresses are in the range of 0~254. Communication address equals to 0 means
broadcast to all PLCs. PLC will not respond to a broadcast message. PLC will reply a normal message
to the master device when communication address is not 0.
Example, ASCII codes for communication address 16 in Decimal. (16 in Decimal = 10 in Hex)
(ADR 1, ADR 0)=’1’,’0’Ö’1’=31H, ‘0’ = 30H

4.2.3 LRC CHK (checksum)
LRC (Longitudinal Redundancy Check) is calculated by summing up the Hex values from ADR1 to last
data character then finding the 2’s-complement negation of the sum.
Example: Read the content of register at address 0401H. 01H+03H+04H+01H+00+01H = 0AH.

Exception response:
The PLC is expected to return a normal response after receiving command messages from the master
device. The following table depicts the conditions that either a no response or an error response is
replied to the master device.
1.
The PLC did not receive a valid message due to a communication error; thus the PLC has no
response. The master device will eventually process a timeout condition.
2.
The PLC receives a valid message without a communication error, but cannot accommodate it,
an exception response will return to the master device. In the exception response, the most
significant bit of the original command code is set to 1, and an exception code explaining the
condition that caused the exception is returned.

4.3.3 CRC CHK (check sum)
The CRC Check starts from “Slave Address” and ends in “The last data content.” Calculation of CRC:
Step 1: Set the 16-bit register (CRC register) = FFFFH.
Step 2: Operate XOR on the first 8-bit message (Address) and the lower 8 bits of CRC register. Store
the result in the CRC register
Step 3: Right shift CRC register for a bit and fill “0” into the highest bit.
Step 4: Check the lowest bit (bit 0) of the shifted value. If bit 0 is 0, fill in the new value obtained at step
3 to CRC register; if bit 0 is NOT 0, operate XOR on A001H and the shifted value and store the result in
the CRC register.
Step 5: Repeat step 3 – 4 to finish all operation on all the 8 bits.
Step 6: Repeat step 2 – 5 until the operation of all the messages are completed. The final value
obtained in the CRC register is the CRC checksum. Care should be taken when placing the LOW byte
and HIGH byte of the obtained CRC checksum.
Calculation example of the CRC Check using the C language:
unsigned char* data
Å // index of the command message
unsigned char length
Å // length of the command message
unsigned int crc_chk(unsigned char* data, unsigned char length)
{
int j;
unsigned int reg_crc=0Xffff;

Exception response:
The PLC is expected to return a normal response after receiving command messages from the master
device. The following content depicts the conditions that either no response situation occurs or an error
response is replied to the master device.
1.
The PLC did not receive a valid message due to a communication error; thus the PLC has no
response. In this case, condition of communication timeout has to be set up in the master device
2.
The PLC receives a valid message without a communication error, but cannot accommodate it. In
this case, an exception response will return to the master device. In the exception response, the
most significant bit of the original command code is set to 1, and an exception code explaining
the condition that caused the exception is returned.

Explanation:
STL Sn constructs a step point. When STL instruction appears in the program, the main program will
enter a step ladder status controlled by steps. The initial STL program has to start from S0 ~ S9 as
initial step points. The No. of Step points cannot be repeated.

Explanation:
RET instruction indicates the end of a step ladder program starting from S0 ~ S9, i.e. the execution
returns to main program after RET is executed. Maximum 10 initial steps (S0 ~ S9) can be applied
and every initial step requires a RET instruction as an end of STL program. With the step ladder
program composed of STL/RET instructions, SFC can perform a step by step control process.

Sequential Function Chart (SFC)
In the application of automation control, a seamless combination between electrical control and
mechanical control is required for completing an automation process. The sequential control of
automation process can be divided into several steps (states). Each step is designated with own
5-2

action and the transition from one step to another generally requires some transition criteria
(condition). The action of the previous step finishes as long as all criteria is true. When next step
begins, the action of previous step will be cleared. The step-by-step transition process is the
concept for designing sequential function chart (SFC).
Features:
1.
Users do not have to consider the sequential relationship

between outputs as general ladder logic because STL

operation process can execute multiple outputs or interlocked
outputs automatically. An easy sequential design between the
steps is the only thing required to control the machines.

2.
The actions in SFC are easy to understand. Also, it’s easy to
do a trial operation, error detecting or period maintenance.
3.
S24
X3
SFC functions as a flow chart. The STL operation works on
the internal step relay S, which is also the step points
representing each state in SFC. When current step is finished,
the program proceeds to the next step according to the
transition condition and the desired continuous control
purpose can be achieved by this process.

Cycle process can be performed. Please refer to the SFC
opposite. Initial step S0 transfers to general step S21 by
transition condition X0. S21 transfers to S22 or jumps to S24
by the condition X1 and X2. The process finally proceeds to
S25 then a single cycle process is completed when S25
returns to S0 with transition condition X6 fulfilled.

Step jump. Used for a step to jump to another non-adjacent step. (Jumping
up/down to non-adjacent steps in the same sequence, returning to initial step, or
jumping among different sequences.)
Transition condition. The transition condition to move between each step point.
Alternative divergence. Alternative divergence is used for a step point to
transfer to different corresponding step points by different transition conditions.
Alternative convergence. Alternative convergence is used for two step points or
more to transfer to the same step point according to transition condition.
Simultaneous divergence. Simultaneous divergence is used for a step point to
transfer to two step points or more by the same transition condition.
Simultaneous convergence. Simultaneous convergence is used for two step
points or more to transfer to the same step point with the same transition
condition when multiple conditions are fulfilled at the same time.
5.3
The Operation of STL Program
Step ladder diagram (STL) is a programming method for users to write a program which functions
similar to SFC. STL provides PLC program designers a more readable and clear programming
method as drawing a flow chart. The sequences or steps in the below SFC is quite understandable
and can be translated into the ladder diagram opposite.
STL program starts with STL instruction and ends with RET instruction. STL Sn constructs a step
point. When STL instruction appears in the program, the main program will enter a step ladder
status controlled by steps. RET instruction indicates the end of a step ladder program starting from
initial steps S0 ~ S9 and every initial step requires a RET instruction as an end of STL program.
If there is no RET instruction at the end of a step sequence, errors will be detected by WPLSoft.

5. Sequential Function Chart
Actions of Step Points:
STL program is composed of many step points, and each step point represents a single task in the
STL control process. To perform a sequential control result, every step point needs to do 3 actions.
1.
Drive output coils
2.
Designate the transition condition
3.
Designate which step will take over the control from the current step
Example:

Explanation:
When S10 = ON, Y0 and Y1 will be ON. When X0 = ON, S20 will be ON and Y20 will be ON. When
S10 = OFF, Y0 will be OFF but Y1 will still be ON (SET instruction is applied on Y1, so Y1 will be ON
and latched.)
STL Transition:
When step point Sn is ON, its following output circuit will be activated. When Sn = OFF, its following
output circuit will be OFF. The interval between the activation of the step point and its following
output circuit is one scan cycle.
Repeated Usage of Output Coil:
4.
Output coils of the same number could be used
in different step points.

of output coils should be avoided. 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.

repeatedly in non-adjacent steps.

Transfer of Step Points:
SET Sn and OUT Sn instructions are used to enable (or transfer to) another step. Because there
can be many step control sequences (i.e. the initial steps starting with S0 ~ S9) existing in the
program. The transfer of a step can take place in the same step sequence, or be transferred to
different step sequence. Usages of SET Sn and OUT Sn are different according to the transfer
methods. Please see the explanations below

Used for driving the next step in the same sequence. After the transition, all output in the previous
step will be OFF.

When SET S12 executes,

OUT Sn
Used for 1: returning to the initial step in the same step sequence, 2: jumping up/down to
non-adjacent steps in the same sequence, or 3: driving steps in different sequences. After the
transition, all outputs in the previous step will be cleared.

Cautions for Driving Output Point:
Once LD or LDI instructions are written into the second line after the step point, the bus will not be
able to connect output coils directly otherwise errors will occur when compiling the ladder diagram.

DO NOT use MC/MCR instruction in the step.
2.
DO NOT use STL instruction in a general subroutine or interruption subroutine.
3.
CJ instruction can be used in STL instruction, however this is not recommended because the
actions will thus become more complicated.

The execution results by the PLC are the same. However, if there are many conditions or
actions in S10, it is recommended to modify the diagram in the left into the diagram in the right,
which executes SET S20 after all actions are completed. The sequence will be more
understandable and clear with this modification.

Points to Note for Designing a Step Ladder Program
The first step in the SFC is called the “initial step", S0 ~ S9. Use the initial step as the start of a
sequence and ends with RET instruction.
2.
If no STL instruction is in use, step point S can be used as a general-purpose auxiliary relay..
3.
When STL instruction is in use, the No. of step S cannot be repeated.
4.
Types of sequences:
Single sequence: Only one simple sequence without alternative divergence, alternative
convergence, simultaneous divergence or simultaneous convergence in the program.
Complicated single sequence: Only one sequence with alternative divergence, alternative
convergence, simultaneous divergence and simultaneous convergence in the program.
Multiple sequences: More than one sequence in a program, maximum 10 sequences, S0 ~ S9.
5.
Sequence jump: Multiple sequences are allowed to be written into the step ladder diagram.
z
There are two sequences, S0 and S1. PLC writes in
OUT
S0
OUT
S1
S0 ~ S30 first and S1 ~ S43 next..
z
Users can assign a step in the sequence to jump to
S21
any step in another sequence.
z
S41
OUT
S42
When the condition below S21 is fulfilled, the sequence
will jump to step S42 in sequence S1, which is called
S30
S43
“sequence jump.”

Restrictions on diverging sequence: Please refer to section 5.5 for examples
a)
Max. 8 step points could be used for single divergence sequence.
b)
Max. 16 step points could be used for the convergence of multiple diverted sequences.
c)
Users can assign a step in the sequence to jump to any step in another sequence.
Reset step points and disable outputs
a)
Use the ZRST instruction to reset (turn off) a specified step sequence..
b)
Set ON the flag M1034 to disable Y outputs.
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 powered up again, PLC will resume the status before power-off
and executes from the interrupted point. Please be aware of the area for the latched steps.

Types of Sequences
Single Sequence: The basic type of sequence
The first step in a step ladder diagram is called initial step, ranged as S0 ~ S9. The steps following
the initial step are general steps numbered as S10 ~ S1023. When IST instruction is applied, S10 ~
S19 will become the steps for zero return operation.
1.
Single Sequence without Divergence and Convergence
After a sequence is completed, the control power on the steps will be transferred to the initial
step.

1.
Structure of Simultaneous Divergence
When the condition at the current step is true, the step can be transferred to multiple steps. For
example, when X0 = ON, S20 will be simultaneously transferred to S21, S22, S23 and S24.

When the individual condition at the current status is true, the step will be transferred to
another individual step. For example, 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.

D1 The
D2: The greatest No. of step points in auto mode.
Explanations:
1.
The IST is a handy instruction specifically for the initial state of the step ladder operation
modes.
2.
The range of D1 and D2 : S20~S911, D1 < D2.
3.
IST instruction can only be used one time in a program.

X20
S20
S60
X20: Individual operation (Manual operation)
X24: Continuous operation
X21: Zero return
X25: Zero return start switch
X22: Step operation
X26: Start switch
X23: One cycle operation
X27: Stop switch
When IST instruction is executed, the following special auxiliary relays will be assigned
automatically.
M1040: Movement inhibited
S0: Manual operation/initial state step point
M1041: Movement start
S1: Zero point return/initial state step point
M1042: Status pulse
S2: Auto operation/initial state step point
M1047: STL monitor enable
2.
When IST instruction is used, S10~S19 are occupied for zero point return operation and
cannot be used as a general step point. In addition, when S0~S9 are in use, S0 initiates

5. Sequential Function Chart
“manual operation mode”, S1 initiates “zero return mode” and S2 initiates “auto mode”. Thus,
the three step points of initial state have to be programmed in first priority.
3.
When S1 (zero return mode) is initialized, i.e. selected, zero return will NOT be executed if any
of the state S10~S19 is ON.
4.
When S2 (auto mode) is initialized, i.e. selected, auto mode will NOT be executed if M1043 =
ON or any of the state between D1 to D2 I is ON.

Control purpose:
Select the big balls and small balls and move them to corresponding boxes. Configure the
control panel for each operation.
2.
Motion of the Robot arm:
lower robot arm, clip balls, raise robot arm, shift to right, lower robot arm, release balls, raise
robot arm, shift to left to finish the operation cycle.

Single step: the operation proceeds with one step every time when Auto ON is
pressed.
z
One cycle operation: press Auto ON at zero position, the operation performs one full
cycle operation and stops at zero point. If Auto OFF is pressed during the cycle, the
operation will pause. If Auto ON is pressed again, the operation will resume the cycle
and stop at zero point.
z
Continuous operation: press Auto ON at zero position, the operation will perform
continuous operation cycles. If Auto OFF is pressed, the operation will stop at the end
of the current cycle.

Common Problems and Solutions
The following tables list some common problems and troubleshooting procedures for the PLC system
in the event of faulty operation.
System Operation
Symptom
All LEDs are OFF
Troubleshooting and Corrective Actions
1.
2.
Check the power supply wiring.
Check If the power supplied to the PLC control units is in the range of
the rating.
3.
Be sure to check the fluctuation in the power supply.
4.
Disconnect the power supply wiring to the other devices if the power
supplied to the PLC control unit is shared with them.
If the LEDs on the PLC control unit turn ON at this moment, the
capacity of the power supply is not enough to control other devices
as well. Prepare another power supply for other devices or increase
the capacity of the power supply.
ERROR LED is
flashing
5.
If the POWER LED still does not light up when the power is on after
the above corrective actions, the PLC should be sent back to the
dealer or the distributor whom you purchased the product from.
1.
If the ERROR LED is flashing, the problem may be an invalid
commands, communication error, invalid operation, or missing
instructions, error indication is given by self-checking function and
corresponding error code and error step are stored in special
registers. The corresponding error codes can be read from the
WPLSoft or HPP. Error codes and error steps are stored in the
following special registers.
Error code: D1004
Error step: D1137
6-2
2.
If the connections between the PLC are failed and the LED will flash
rapidly, this indicates the DC24V power supply is down and please
check for possible DC24V overload.
3.
The LED will be steady if the program loop execution time is over the
preset time (set in D1000), check the programs or the WDT (Watch
Dog Timer). If the LED remains steady, download user program
again and then power up to see if the LED will be OFF. If not, please
check if there is any noise interference or any foreign object in the
PLC.

Troubleshooting and Corrective Actions
When input indicator LEDs are OFF,
1.
Check the wiring of the input devices.
2.
Check that the power is properly supplied to the input terminals.
3.
If the power is properly supplied to the input terminal, there is
probably an abnormality in the PLC’s input circuit. Please contact
your dealer.
4.
If the power is not properly supplied to the input terminal, there is
probably an abnormality in the input device or input power supply.
Check the input device and input power supply.
When input indicator LEDs are ON,
Diagnosing Output
Malfunction
1.
Monitor the input condition using a programming tool. If the input
monitored is OFF, there is probably an abnormality in the
PLC’s input circuit. Please contact your dealer.
2.
If the input monitored is ON, check the program again. Also, check
the leakage current at the input devices (e.g., two-wire sensor) and
check for the duplicated use of output or the program flow when a
control instruction such as MC or CJ is used.
3.
Check the settings of the I/O allocation.
When output indicator LEDs are ON,
1.
Check the wiring of the loads.
2.
Check if the power is properly supplied to the loads.
3.
If the power is properly supplied to the load, there is probably an
abnormality in the load. Check the load again.
4.
If the power is not supplied to the load, there is probably an
abnormality in the PLC’s output circuit. Pleas contact your dealer.
When output indicator LEDs are OFF,
1.
Monitor the output condition using a programming tool. If the output
monitored is turned ON, there is probably a duplicated output error.
2.
Forcing ON the output using a programming tool. If the output
indicator LED is turned ON, go to input condition check. If the output
LED remains OFF, there is probably an abnormality in the PLC’s
output circuit. Please contact your dealer.

Error code Table (Hex)
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.

7.1
The Introduction of CANopen
¾
Due to the simple wiring, immediate communication, strong debugging ability, stable
communication, and low cost, the CANopen network is widely used in fields such as industrial
automation, automotive industry, medical equipment industry, and building trade.
¾ The CAN port, which conforms to the basic communication protocol of CANopen DS301, is
built in the PLC, can work in a master mode or a slave mode.
¾ This chapter explains the functions of CANopen. The functions are mainly controlled by the
special auxiliary relay M1349. If M1349 is ON, the CANopen functions are enabled. If M1349
is OFF, the CANopen functions are disabled. In a master mode, the CANopen functions can
support slave 1~slave 16.
¾ The CANopen network configuration software for DVP-ES2-C is CANopen Builder. The
CANopen station address and the communication rate are set by means of this software. The
programming software for DVP-ES2-C is WPLSoft or ISPSoft.
¾ This chapter mainly focuses on the CANopen functions. If users do not understand the
professional terms mentioned in the introduction of the functions, they can refer to section 7.3
for more information.
7.1.1 The Description of the CANopen Functions
¾ If the CAN port functions as a master, it has the following functions.
It support the standard CANopen protocol DS301 V4.02.
It supports the NMT (network management object) service.
It supports the NMT state control.
The NMT state control can be used to control the state of a slave in the CANopen
network.
It supports the NMT error control.
The NMT error control is used to detect the disconnection of a slave. The NMT error
control can be classified into two types, i.e. Heartbeat and Node Guarding. The PLC
supports Heartbeat, but do not support Node Guarding.
It supports the PDO (process data object) service.
The PDO message is used to transmit the immediate input data and output data.
It supports 128 RxPDO at most, and 390 bytes at most.
It supports 128 TxPDO at most, and 390 bytes at most.
The PDO transmission type: The synchronous mode, and the asynchronous mode
It supports the SDO (service data object) service.
The SDO can be used to read the parameter from a slave, write the parameter into a
slave, or configure the parameter for a slave.
It supports the standard SDO transmission mode.
It supports the automatic SDO functions. Twenty pieces of data at most can be written
into a slave.
It supports the use of the SDO service in a PLC ladder diagram to read the data from a
slave or write the data into a slave.
It supports the service of reading the emergency from a slave.
The service of reading the emergency from a slave can be used to read an error or an
alarm from a slave.
Five emergencies can be stored in a slave.
The emergency can be read through a PLC ladder diagram.
It supports the SYNC object (synchronous object) service.
Several devices can operate synchronously through the synchronous object service
The CANopen communication rates which are supported are 20K, 50K, 125K, 250K, 500K,
1Mbps.

1) Users should use standard Delta cables when creating the CANopen network. These cables
are the thick cable TAP-CB01, the thin cable TAP-CB02, and the thin cable TAP-CB10. The
communication cables should be away from the power cables.
2) TAP-TR01. CAN+ and CAN-, which are at the endpoints of the network, should be connected
to 120 ohm resistors. Users can purchase the standard Delta terminal resistor TAP-TR01.
3) The limitation on the length of the CANopen network
The transmission distance of the CANopen network depends on the transmission rate of the
CANopen network. The relation between the transmission rate and the maximum

The CANopen Protocol
7.3.1 The Introduction of the CANopen Protocol
The CAN (controller area network) fieldbus only defines the physical layer and the data link layer.
(See the ISO11898 standard.) It does not define the application layer. In the practical design, the
physical layer and the data link layer are realized by the hardware. The CAN fieldbus itself is not
complete. It needs the superior protocol to define the use of 11/29-bit identifier and that of 8-bytedata.
The CANopen protocol is the superior protocol base on CAN. It is one of the protocols defined and
maintained by CiA (CAN-in-Automation). It is developed on the basis of the CAL (CAN application
layer) protocol, using a subset of the CAL communication and service protocols.
The CANopen protocol covers the application layer and the communication profile (CiA DS301). It
also covers a framework for programmable devices (CiA 302), the recommendations for cables
and connectors (CiA 303-1), and SI units and prefix representations (CiA 303-2).
In the OSI model, the relation between the CAN standard and the CANopen protocol is as follow.

¾ The object dictionary
CANopen uses an object-based way to define a standard device. Every device is represented
by a set of objects, and can be visited by the network. The model of the CANopen device is
illustrated below. As the figure below shows, the object dictionary is the interface between the
communication program and the superior application program.
The core concept of CANopen is the device object dictionary (OD). It is an orderly object set.
Every object adopts a 16-bit index for addressing. In order allow the visit to the single element
in the data structure, it also defines, an 8-bit subindex. Every node in the CANopen network
has an object dictionary. The object dictionary includes the parameters which describe the
device and the network behavior. The object dictionary of a node is described in the electronic
data sheet (EDS).
7.3.2 The CANopen Communication Object
The CANopen communication protocol contains the following communication objects.
¾ PDO (process data object)
The PDO provides the direct visit channel for the device application object, is used to
transmit the real-time data, and has high priority. Every byte in the PDO CAN message
data list is used to transmit the data. The rate of making use of the message is high.
There are two kinds of uses for PDOs. The first is data transmission and the second data
reception. They are distinguished by Transmit-PDOs (TxPDOs) and Receive-PDOs
(RxPDOs). Devices supporting TxPDOs are PDO producers, and devices which are able to
7-9
D V P - E S 2 / E X 2 / S S 2 / S A2 / S X 2 / S E O p e r a t i o n M a n u a l - P r o g r a m m i n g
receive PDOs are called PDO consumers.
The PDO is described by means of the “producer/consumer mode”. The data is transmitted
from one producer to one or many consumers. The data which can be transmitted are
limited to 1-byte data to 8-byte data. After the data is transmitted by the producer, the
consumer does not need to reply to the data. Every node in the network will detect the data
information transmitted by the transmission node, and decides whether to process the data
which is received.
Every PDO is described by two objects in the object dictionary: The PDO communication
parameters and the PDO mapping parameters
The PDO communication parameters: The COB-ID which will be used by PDO, the
transmission type, the prohibition time, and the cycle
of the counter
The PDO mapping parameters: They include the object list in an object dictionary. These
objects are mapped into the PDO, including the data length
(in bits). To explain the contents of the PDO, the producer
and the consumer have to understand the mapping.
The PDO transmission mode: synchronous and asynchronous
Synchronous: Synchronous periodic and synchronous non-periodic
Asynchronous: The PDO is transmitted when the data changes, or it is transmitted after a
trigger.
The transmission modes supported by are as follows.
Type

Periodic
Non-periodic Synchronous Asynchronous

Mode 0: The PDO information is transmitted only when the PDO data changes and the
synchronous signal comes.
Modes 1~240: One piece of PDO information is transmitted every 1~240 synchronous
signals.
Mode 254: The trigger is defined the manufacturer. The definition of the PLC is the same as
mode 255.
Mode 255: PDO is transmitted when the data changes, or it is transmitted after a trigger.
All the data in the PDO has to be mapped from the object dictionary. The following is an
example of the PDO mapping.

Data
¾ SDO (service data object)
The SDO is used to build the client/server relation between two CANopen devices. The
client device can read the data from the object dictionary of the server device, and write the
data into the object dictionary of the server device. The visit mode of the SDO is
“client/server” mode. The mode which is visited is the SDO server. Every CANopen device
has at least one service data object which provides the visit channel for the object
dictionary of the device. SDO can read all objects in the object dictionary, and write all
objects into the object dictionary.
The SDO message contains the index information and the subindex information which can
be used to position the objects in the object dictionary, and the composite data structure
can easily pass the SDO visit. After the SDO client sends the reading/writing request, the
SDO server replies. The client and the server can stop the transmission of the SDO .The
requested message and the reply message are divided by different COB-IDs.
The SDO can transmit the data in any length. If the data length is more than 4 bytes, the
data has to be transmitted by segment. The last segment of the data contains an end flag.
The structures of the SDO requested message and reply message are as follows.

¾ NMT (network management object)
The CANopen network management conforms to the “master/slave” mode. Only one NMT
master exists in the CANopen network, and other nodes are considered slaves. NMT realized
three services. They are module control services, error control services, and boot-up services.
Module control services
The master node in the CANopen network controls the slave by sending the command. The
slave executes the command after it received the command. It does not need to reply. All
CANopen nodes have internal NMT states. The slave node has four states. They are the
initialization state, the pre-operational state, the operational state, and the stop state. The
state of the device is illustrated below.

(2) After the initialization is complete, the device automatically enters the Pre-operational
state.
(3)(6) The remote node is started.
(4)(7) The device enters the Pre-operational state.
(5)(8) The remote node is stopped.
(9)(10)(11) The application layer is rest.
(12)(13)(14) The communication is reset.
(15) After the initializing is complete, the device automatically enters the “reset application”
state.
(16) After the “reset application” state is complete, the device automatically enters the
“reset communication” state.
The relation between the communication object and the state is shown below. The
communication object service can be executed only in a proper state. For example, SDO
can be executed only in the operational state and in the pre-operational state.

Error control services
The error control service is used to detect the disconnection of the node in the network. The
error control services can be classified into two types, i.e. Heartbeat and Node Guarding.
The PLC only supports Heartbeat. For example, the master can detect the disconnection of
the slave only after the slave enables the Heartbeat service.
The Heartbeat principle is illustrated as follows. The Hearbeat producer transmits the
Heartbeat message according to the Heartbeat producing time which is set. One or many
Heartbeat consumers detect the message transmitted by the Heartbeat producer. If the
consumer does not receive the message transmitted by the producer within the timeout
period, the CANopen communication is abnormal.

Boot-up services
After the slave completes the initialization and enters the pre-operational state, it transmits
the Boot-up message.
¾ Other predefined CANopen communication objects (SYNC and EMCY)
SYNC Object (Synchronous object)
The synchronous object is the message broadcasted periodically by the master node in the
CANopen network. This object is used to realize the network clock signal. Every device
decides whether to use the event and undertake the synchronous communication with other
network devices according to its configuration. For example, when controlling the driving
device, the devices do not act immediately after they receive the command sent by the
master. They do act until they receive the synchronous message. In this way, many devices
can act synchronously.
The format of the SYNC message:
COB-ID
80 (hex)
Emergency object
The emergency object is used by the CANopen device to indicate an internal error. When
an emergency error occurs in the device, the device sent the emergency message
(including the emergency error code), and the device enters the error state. After the error
is eliminated, the device sends the emergency message, the emergency error code is 0,
and the device enters the normal state.

If the value is 0, no error occurs. If the value is 1, a normal error occurs. If the value is
H’80, an internal error occurs in the device.
7.3.3 The Predefined Connection Set
In order to decrease the configuration workload of the network, CANopen defines a default
identifier. In the predefine connection set, the structure of the 11-bit identifier is as follows.

When M0=ON, DVP-ES2-C sends out the first request message and D6000 should be
101(hex) after the response message is transmitted back successfully. In program, if the
value of D6000 is judged as 101(hex), the ReqID is changed into 2 and D6250 is given a new
value 201(hex) and DVP-ES2-C sends out the request message again. By dong so, the
real-time reading can be realized. After reading succeeds, the data returning from the target
device are stored in D6000~D6005. The value of D6005: 100（hex）is the read value of P0-09.

Application Example
DVP-ES2-C is used to control Delta A2 servo rotation and monitor the actual rotation speed of
motor in real time. The principle of operation is to map the relevant parameters of servo drive to the
corresponding PDO and read or write the relevant parameters of servo drive through the CAN bus
to accomplish the control requirement.

“PDO Mapping” and “Properties”
Used for setting the mapping parameter and transmission type of PDO.
For the details on the function buttons mentioned above, please refer to Section 11.1.1 in
the help file of CANopen Builder software.
PDO Mapping:
RxPDO1: the mapping parameter P1-09; transmission type 255.
RxPDO2: the mapping parameter P3-06, P4-07; transmission type 255.
TxPDO1: the mapping parameter P0-09; transmission type 1.
PDO transmission type :
PDO can be classified into RxPDO and TxPDO. RxPDO data are sent from master to slave
and TxPDO data are sent from slave to master.
7-32
7 C AN o p e n F u n c t i o n a n d O p e r a t i o n
PDO transmission type can be synchronous transmission and asynchronous transmission.
In synchronous transmission, master will send out the SYNC message in the fixed cycle.
The length of the cycle is set in master properties dialog box with the default value: 50ms.
In asynchronous transmission, the message is sent out once the PDO mapping parameter
is changed.
PDO Transmission types in details are introduced in the following table.
Transmission Type
RxPDO
Description
Once any change for the mapped data
happens, RxPDO data are sent out
immediately. The data that slave receives
are valid only when receiving the next
SYNCH message. If no change for RxPDO
data, they are not sent out.
0
TxPDO
Once any change for the mapped data
happens and slave receives the SYNC
message, the data are sent out immediately.
The TxPDO data are valid immediately after
master receives them. If no change for
TxPDO data, the data are not sent out.
RxPDO
After N messages are sent out and no
matter whether the mapped data are
changed, the data that slave receives will be
valid only when receiving the next SYNCH
message.
N
（N:1~240）
TxPDO
After N messages are sent out and no
matter whether the mapped data are
changed, the data that master receives will
be valid at once.
RxPDO
The mapped data are sent out immediately
once changed and they are valid once they
are received by slave. RxPDO data will not
be sent out if no change for the data.
TxPDO
Slave sends out the data once every one
Event timer time and after that, the TxPDO
data are not allowed to be sent out within an
inhibit timer time.
When Event timer and Inhibit timer are both
equal to 0, TxPDO data are sent to master
immediately once changed and the data
that master receives will be valid at once.

Note:
1> Synchronous transmission type can fulfill multi-axis motion at the same time.
2> If user is going to monitor the real-time changing parameter such as the actual rotation
speed of the motor, we suggest TxPDO should be set as the synchronous transmission
type in case the frequent changing of slave data causes to block the CANopen network.

Program explanation:
While DVP-ES2-C is running for the first time, set the parameter P3-06 of servo drive to F.
When M0 turns from OFF to ON, write K256 to D6282 and then the value is written to P1-09
of servo parameter through RxPDO1.
When M1 turns from OFF to ON, turn P2-12 on and call the speed specified by parameter
P1-09 of servo for rotation.
When M1 turns from ON to OFF, the speed command becomes 0 and the motor stops
running.

A.1 Installing the USB Driver
This section introduces the installation of the DELTA PLC USB driver in the computer. After the
driver is installed, the USB interface can be used as the serial port (RS-232). Please use the
standard USB cable. The length of the cable should be within fiver meters.
Installing the driver
The personal computer and the PLC are connected through the USB and the mini USB cable. After
they are connected, users can find USB Device in the Device Manager window.
Click the right mouse button, and select Update Driver… to open the Hardware Update Wizard
window. Click Browse to specify the folder, and then click Next to start the installation of the driver.

Ap p e d n d i x A
After the driver is installed, users can find the Delta PLC device and the communication port
assigned to it in the Device Manger window. The usage of this device is the same as that of
RS-232.

Select Communication Setting in Options to open the Communication Setting window. Select
RS232 in the Connection Setup box, select the communication port assigned by the USB in the
Communication Setting box, and click OK. After the communication setting is complete, users
can find that RS232 in the communication work area is checked. They can download the program
to the PLC and upload the program from the PLC through the USB, and can use the online mode.
