WARNING Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
!
5Application Precautions
xiv
•Always connect to a class-3 ground (to 100 Ω or less) when installing the Units.
Not connecting to a class-3 ground may result in electric shock.
•Always turn off the power supply to the PC before attempting any of the follow-
ing. Not turning off the power supply may result in malfunction or electric
shock.
•Mounting or dismounting I/O Units, CPU Units, or any other Units.
•Assembling the Units.
•Connecting or wiring the cables.
•Connecting or disconnecting the connectors.
Caution Failure to abide by the following precautions could lead to faulty operation of the
PC or the system, or could damage the PC or PC Units. Always heed these pre-
cautions.
•Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes.
•Construct a control circuit so that power supply for the I/O circuits does not
come ON before power supply for the Unit. If power supply for the I/O circuits
comes ON before power supply for the Unit, normal operation may be tempo-
rarily interrupted.
•If the operating mode is changed from RUN or MONITOR mode to PROGRAM
mode, with the IOM Hold Bit ON, the output will hold the most recent status. In
such a case, ensure that the external load does not exceed specifications. (If
operation is stopped because of an operation error (including FALS instruc-
tions), the values in the internal memory of the CPU Unit will be saved, but the
outputs will all turn OFF.)
•Always use the power supply voltage specified in the operation manuals. An
incorrect voltage may result in malfunction or burning.
•Take appropriate measures to ensure that the specified power with the rated
voltage and frequency is supplied. Be particularly careful in places where the
power supply is unstable. An incorrect power supply may result in malfunction.
•Install external breakers and take other safety measures against short-circuit-
ing in external wiring. Insufficient safety measures against short-circuiting may
result in burning.
•Do not apply voltages to the Input Units in excess of the rated input voltage.
Excess voltages may result in burning.
•Do not apply voltages or connect loads to the Output Units in excess of the
maximum switching capacity. Excess voltage or loads may result in burning.
•Disconnect the functional ground terminal when performing withstand voltage
tests. Not disconnecting the functional ground terminal may result in burning.
•Install the Unit properly as specified in the operation manual. Improper installa-
tion of the Unit may result in malfunction.
•Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in the relevant manuals. Incorrect
tightening torque may result in malfunction.
•Be sure to attach the supplied labels when wiring in order to prevent wiring cut-
tings from entering in the Unit.
•Remove the label after the completion of wiring to ensure proper heat dissipa-
tion. Leaving the label attached may result in malfunction.
•Use crimp terminals for wiring. Do not connect bare stranded wires directly to
terminals. Connection of bare stranded wires may result in burning.
•Double-check all the wiring before turning on the power supply. Incorrect wir-
ing may result in burning.

5Application Precautions
xv
•Be sure that the terminal blocks, expansion cables, and other items with lock-
ing devices are properly locked into place. Improper locking may result in mal-
function.
•Check the user program for proper execution before actually running it on the
Unit. Not checking the program may result in an unexpected operation.
•Confirm that no adverse effect will occur in the system before attempting any of
the following. Not doing so may result in an unexpected operation.
•Changing the operating mode of the PC.
•Force-setting/force-resetting any bit in memory.
•Changing the present value of any word or any set value in memory.
•Resume operation only after transferring to the new CPU Unit the contents of
the DM and HR Areas required for resuming operation. Not doing so may result
in an unexpected operation.
•Do not pull on the cables or bend the cables beyond their natural limit. Doing
either of these may break the cables.
•Do not place objects on top of the cables. Doing so may break the cables.
•When replacing parts, be sure to confirm that the rating of a new part is correct.
Not doing so may result in malfunction or burning.
•Before touching the Unit, be sure to first touch a grounded metallic object in
order to discharge any static built-up. Not doing so may result in malfunction or
damage.
•Do not touch the Expansion I/O Unit Connecting Cable while the power is
being supplied in order to prevent any malfunction due to static electricity.
•When using a thermocouple-input type Temperature Sensor Unit, observe the
following precautions:
•Do not remove the cold junction compensator attached at the time of deliv-
ery. If the cold junction compensator is removed the Unit will not be able to
measure temperatures correctly.
•Each of the input circuits is calibrated with the cold junction compensator
attached to the Unit. If the Unit is used with the cold junction compensator
from other Units, the Unit will not be able to measure temperatures cor-
rectly.
•Do not touch the cold junction compensator. Doing so may result in incor-
rect temperature measurement.
Caution Always clear memory before beginning to program the CPM1A. Although
memory is cleared before the CPU Unit is shipped (except for bits with specific
functions), AR 1314, which turns ON when the internal capacitor cannot back up
memory, may have turned ON during shipment.
Caution If the CPM1A will be turned off for periods exceeding the data backup period of
the internal capacitor, design the system so that it will not be influenced if data in
the DM, HR, and CNT areas is cleared when power is turned off.
Caution Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to
the CPM1A after changing from a Programming Device any data that is backed
up in flash memory. This data includes the user program, read-only DM area
(DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).
5Application Precautions
xvi
•The user program and memory area data in the CPM1A are backed up either
by an internal capacitor or in flash memory as shown in the following table.
Backup method Data
Internal capacitor Read/write DM area (DM 0000 to DM 0999, DM 1022, and
DM 1023)
Error log area (DM 1000 to DM 1021)
HR area (HR 00 to HR 19)
Counter area (CNT 000 to CNT 127)
Flash memory User program
Read-only DM area (DM 6144 to DM 6599)
PC Setup (DM 6600 to DM 6655)
Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is
turned off and all contents will be cleared the next time power is turned on.
(The PC Setup setting in DM 6601 can be used to back up this data. Refer to
details on the PC Setup later in this manual for details.)
2. The bits in the AR and SR areas have special functions and are set accord-
ing to these functions when power is turned on.
•The capacitor backup time depends on the ambient temperature, as shown in
the following graph. The backup time, however, assumes that the capacitor is
fully charged, which requires that power be supplied to the CPU Unit continu-
ously for at least 15 minutes.
Backup time (days)
Ambient temperature (C)

25 40 80
If the power remains off for a period exceeding the data backup period,
AR 1314 will turn ON to indicate that the capacitor can no longer back up data
and the data backed up by the capacitor will be cleared. AR 1314 will remain
ON unless it is turned OFF using I/O monitor operations, using memory clear
operations, or from the user program.
If desired, the PC Setup setting in DM 6604 can be set to create a fatal error
and thus stop the system when AR 1314 goes ON.
•The data stored in flash memory will not be lost even if power remains off for a
period exceeding the data backup period, because the data stored in flash
memory will be read to the CPU Unit when the CPM1A is turned on.
•If the power is turned off without changing the mode from PROGRAM mode to
RUN or MONITOR mode after having made changes in the data that is backed
up in flash memory, the changes will not be written to flash memory. If the
power is then left off for more than 20 days (at 25C), the changes (i.e., the
contents of the RAM) will be erased and the data values will become unde-
fined.

6 EC Directives
6-1 Applicable Directives
•EMC Directives
•Low Voltage Directive
6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan-
dards in the system used by the customer, however, must be checked by the
customer.
EMC-related performance of the OMRON devices that comply with EC Direc-
tives will vary depending on the configuration, wiring, and other conditions of the
equipment or control panel on which the OMRON devices are installed. The cus-
tomer must, therefore, perform the final check to confirm that devices and the
overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61131-2
EMI (Electromagnetic Interference): EN50081-2
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to
1,500 VDC meet the required safety standards for the PC (EN61131-2).
6-3 Conformance to EC Directives
The CPM1A PCs (transistor output models) comply with EC Directives. Relay
output models do not conform to the EC Directives. To ensure that the machine
or device in which the CPM1A PC is used complies with EC directives, the PC
must be installed as follows:
1, 2, 3... 1. The CPM1A PC must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. CPM1A PCs complying with EC Directives also conform to the Common
Emission Standard (EN50081-2). Radiated emission characteristics (10-m
regulations) may vary depending on the configuration of the control panel
used, other devices connected to the control panel, wiring, and other condi-
tions. You must therefore confirm that the overall machine or equipment
complies with EC Directives.
4. The CPM1A with relay output does not conform to the EC Directives. For
devices for use in the EC, use the CPM1, which meets the CE marking
requirements. Further information is available at any of the OMRON offices
or OMRON sales representatives listed on the inside back cover of this
manual.

1-1 CPM1A Features and Functions
1-1-1 CPM1A Features
One-piece Construction The CPM1A CPU Units feature a one-piece construction including 10, 20, 30, or
40 built-in I/O terminals. The following three model groups are available: relay
output models, sink-type transistor output models, and source-type transistor
output models.
CPM1A-10CDR-/10CDT-D/10CDT1-D
(10 I/O terminals) CPM1A-20CDR-/20CDT-D/20CDT1-D
(20 I/O terminals)
CPM1A-30CDR-/30CDT-D/30CDT1-D
(30 I/O terminals) CPM1A-40CDR-/40CDT-D/40CDT1-D
(40 I/O terminals)
Extra I/O Capacity Up to three Expansion I/O Units can be connected to a CPM1A-30CDR-/
30CDT-D/30CDT1-D or CPM1A-40CDR-/40CDT-D/40CDT1-D CPU Unit to
add an extra 8 or 20 I/O points for each, for a maximum of up to 100 I/O points.
Input Filter Function The CPM1A is equipped with a filter function to prevent incorrect operation
caused by chatter or noise in the input signal. The user can select an input time
constant of 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms, 64 ms, or 128 ms.
Low-maintenance Design Flash memory provides memory backup without a battery.
Input Interrupts The CPM1A-10CDR-/10CDT-D/10CDT1-D CPU Units can handle 2 interrupt
inputs; the CPM1A-20CDR-/20CDT-D/20CDT1-D, CPM1A-30CDR-/
30CDT-D/30CDT1-D, and CPM1A-40CDR-/40CDT-D/40CDT1-D CPU Units
can handle 4 interrupt inputs. In addition to normal input interrupts, the CPM1A
has a counter mode that counts high-speed input signals and triggers interrupts
at fixed count multiples.
Quick-response Inputs Quick-response inputs can detect input signals with a pulse width as short as
0.2 ms regardless of their timing during the PC cycle. Quick-response inputs
and interrupt inputs use the same input terminals.
Interval Timer CPM1A PCs have a high-speed interval timer which can be set from 0.5 ms to
319,968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or
repeat scheduled interrupts (scheduled interrupt mode).
High-speed Counter CPM1A PCs have a high-speed counter that can be used in incremental mode
or up/down mode. The high-speed counter can be combined with input inter-
rupts to perform target value control or zone comparison control that isn’t
affected by the PC’s cycle time.
Pulse Output Function The CPM1A transistor output models have an output function capable of output-
ting a pulse of 20 Hz to 2 kHz (single-phase output).
Analog Setting Function The CPM1A PCs have 2 analog volume controls that can be used to make
manual analog settings.
CPM1A Features and Functions Section 1-1
3
Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs.
Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 ana-
log inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O
Units.
The analog input range can be set to 0 to 10 VDC, 1 to 5 VDC, or 4 to 20 mA with a
resolution of 1/256. (The open-circuit detection function can be used with the 1 to
5 VDC and 4 to 20 mA settings.)
The analog output range can be set to 0 to 10 VDC, –10 to 10 VDC, or 4 to 20 mA
with a resolution of 1/256.
A Temperature Sensor Unit can be connected to provide up to 6 inputs for tem-
perature input from sensors, such as thermocouples or platinum resistance
thermometers.
Host Link Communications The CPM1A PCs are compatible with the Host Link, which allows communica-
tions with personal computers. The CPM1A using the Host Link can also com-
municate with Programmable Terminal using host link commands.
An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is
used for 1:N communications.
One-to-one PC Link A data link can be created with a data area in another CPM1A, CQM1, CPM1,
SRM1 or C200HS or C200HX/HE/HG PC. An RS-232C Adapter is used to make
the 1:1 connection.
NT Link Communications High-speed operations can be achieved by providing a direct access by con-
necting the CPM1A to the OMRON Programmable Terminal through the NT Link
Interface. An RS-232C Adapter is used for this connection.
Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a
Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (inter-
nal) and 8 output bits (internal).
The CompoBus/S Network provides distributed CPU control based on a “PC +
compact PC” configuration, which is an improvement on the earlier distributed
I/O control based on a “PC + remote I/O” configuration. The distributed CPU
control makes equipment modular, so designs can be standardized, special
needs can be addressed, and modules can be replaced easily in the event of a
breakdown.

Standard Peripheral Devices The CPM1A uses the same Programming Consoles and SYSMAC Support
Software (SSS) as the C200H/HS, C200HX/HE/HG, CPM1, SRM1, and CQM1
PCs.
Programming operation is possible through the PT screen by using an OMRON

Analog Setting Function CPM1A PCs have 2 variable-resistor adjustment knobs used to control analog
timer and counter settings manually. When one of the adjustments is turned, the
content of the corresponding IR word is set automatically between 0 and 200
(BCD).
Turn the adjustment knob with a Phillips screwdriver.

Analog adjustment 0 IR 250 0000 to 0200
Analog adjustment 1 IR 251
Input Filter Function The input time constant for the CPM1A’s external inputs can be set to 1, 2, 4, 8,
16, 32, 64, or 128 ms. Increasing the input time constant can reduce the effects
of chatter or noise in the input signal.

With the CPM1A, actual response time for each set input time constant for word
000 is different from that for word 001 or later.
Set value Word 000 Word 001 or later
1 ms 1 to 1.5 ms 0.1 to 0.3 ms
2 ms 2 to 2.5 ms 0.7 to 1.5 ms

64 ms 64 to 64.5 ms 24 to 35 ms
128 ms 128 to 128.5 ms 50 to 70 ms
The input response time of the CPM1A is obtained with the following:
2 ms max. (hardware performance) + input time constant (see above table)
+ cycle time

Input Interrupts The CPM1A-10CDR-/10CDT-D/10CDT1-D PCs have 2 interrupt input termi-
nals and the CPM1A-20CDR-/20CDT-D/20CDT1-D, CPM1A-30CDR-/
30CDT-D/30CDT1-D, and CPM1A-40CDR-/40CDT-D/40CDT1-D PCs have
4 interrupt input terminals. There are two modes for input interrupts: input inter-
rupt mode and counter mode.
1, 2, 3... 1. When an interrupt occurs in Input Interrupt Mode, the main program is inter-
rupted and the interrupt program is executed immediately, regardless of the
cycle time.
2. In Counter Mode, external input signals are counted at high speed (up to
1 kHz) and an interrupt is generated each time the count reaches the set
value. When an interrupt occurs, the main program is interrupted and the
interrupt program is executed. The set value can be set from 0 to 65,535.
The following diagram shows the program execution when an interrupt occurs.

Note When not using as interrupt input terminals, the input bits IR 00003 to IR 00006
can be used as normal input terminals.
Caution Although IORF(97) can be used in interrupt subroutines, you must be careful of
the interval between IORF(97) executions. If IORF(97) is executed too frequent-
ly, a fatal system error may occur (FALS 9F), stopping operation. The interval
between executions of IORF(97) should be at least 1.3 ms + total execution time
of the interrupt subroutine.

Quick-response Inputs The CPM1A-10CDR-/10CDT-D/10CDT1-D PCs have 2 quick-response input
terminals and the CPM1A-20CDR-/20CDT-D/20CDT1-D, CPM1A-
30CDR-/30CDT-D/30CDT1-D and CPM1A-40CDR-/40CDT-D/40CDT1-D
PCs have 4 quick-response input terminals. (The same terminals are used for
quick-response inputs and interrupt inputs.)
Quick-response inputs have an internal buffer, so input signals shorter than one
cycle can be detected.

Pulse Output Function Since the CPM1A with transistor output has a pulse output function capable of
outputting a pulse of 20 Hz to 2kHz (single-phase output), a stepping motor can
be controlled by the CPU Unit alone.

A PC with up to 6 temperature inputs for input from thermocouples or platinum
resistance thermometers can be assembled by connecting Temperature Sensor
Units.
CompoBus/S I/O Link Units (Slave Units) can be connected to a CPU Unit. I/O
data (8 inputs and 8 outputs) is transferred between the CPU Unit and the area
allocated to the CompoBus/S Slave. (The I/O data exchanged with the Slave is
internal data; there are no external input or output terminals.)
Note Different types of Expansion Units can be connected at the same time. For ex-
ample, an Expansion I/O Unit, Analog I/O Unit, and CompoBus/S I/O Link Unit,
or an Expansion I/O Unit, Analog I/O Unit, and Temperature Sensor Unit can be
connected to the CPU Unit.

1-2-6 CompoBus/S I/O Link Connections
A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input
points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The
connection is made through a CompoBus/S I/O Link Unit.
From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-
Bus/S I/O Link Unit can be treated just like the area allocated to an Expansion I/O
Unit. The difference is that the bits are not actual I/O points, but I/O bits in the
Master Unit.

capacitor for 20 days at 25C. The capacitor backup time depends on the ambient
temperature. See the graph on the following page for details.

Note 1. Use TIM 000 to TIM 003 when creating a timer using the high-speed timer
instruction to perform interrupt processing.
2. The input interrupt response time is 0.3 ms max.
Memory Backup The user program and memory area data in the CPM1A are backed up either by
an internal capacitor or in flash memory as shown in the following table.
Backup method Data
Internal capacitor Read/write DM area (DM 0000 to DM 0999, DM 1022, and
DM 1023)
Error log area (DM 1000 to DM 1021)
HR area (HR 00 to HR 19)
Counter area (CNT 000 to CNT 127)
Flash memory User program
Read-only DM area (DM 6144 to DM 6599)
PC Setup (DM 6600 to DM 6655)
Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is
turned off and all contents will be cleared the next time power is turned on.
(The PC Setup setting in DM 6601 can be used to back up this data. Refer to
details on the PC Setup later in this manual for details.)
2. The bits in the AR and SR areas have special functions and are set accord-
ing to these functions when power is turned on.
The capacitor backup time depends on the ambient temperature, as shown in
the following graph. The backup time, however, assumes that the capacitor is
fully charged, which requires that power be supplied to the CPU Unit continu-
ously for at least 15 minutes.
Backup time (days)
Ambient temperature (C)

25 40 80
If the power remains off for a period exceeding the data backup period,
AR 1314 will turn ON to indicate that the capacitor can no longer back up data
and the data backed up by the capacitor will be cleared. AR 1314 will remain
ON unless it is turned OFF using I/O monitor operations, using memory clear
operations, or from the user program.
If desired, the PC Setup setting in DM 6604 can be set to create a fatal error
and thus stop the system when AR 1314 goes ON.
The data stored in flash memory will not be lost even if power remains off for a
period exceeding the data backup period, because the data stored in flash
memory will be read to the CPU Unit when the CPM1A is turned on.
If the power is turned off without changing the mode from PROGRAM mode to
RUN or MONITOR mode after having made changes in the data that is backed
up in flash memory, the changes will not be written to flash memory. If the power
is then left off for more than 20 days (at 25C), the changes (i.e., the contents of
the RAM) will be erased and the data values will become undefined.
Specifications Section 2-1
23
Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to
the CPM1A after changing from a Programming Device any data that is backed
up in flash memory. This data includes the user program, read-only DM area
(DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).

3-1 Design Precautions
Observe the following precautions when designing a system incorporating a
CPM1A PC.
3-1-1 Power Supply Wiring
Separate the power supply wiring from the control system, CPM1A system, and
DC I/O system wiring. Separate the control circuits that supply power to the main
Unit from the main circuits using dedicated circuit protectors and fuses.
3-1-2 Interlock and Limit Circuits
WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits (i.e., not in the
Programmable Controller) to ensure safety in the system if an abnormality
occurs due to malfunction of the PC or another external factor affecting the PC
operation. Not providing proper safety measures may result in serious
accidents.
Construct an external interlock circuit if CPM1A outputs are used to perform
reciprocal operations such as controlling the forward and reverse operation of a
motor or if incorrect PC operation could cause accidents or mechanical damage.
Also, construct an external limit circuit to prevent run-away movement in sys-
tems such as position control.
The following diagram shows an example of an interlock circuit.
Interlock Circuit
Motor forward
Motor reverse
MC1
01005 MC2
MC2
01006 MC1
CPM1A
In the interlock circuit above, MC1 and MC2 can’t be ON at the same time even if
CPM1A outputs 01005 and 01006 are both ON (an incorrect PC operation).
3-1-3 Power Supply Voltage
Caution Use the power supply voltages indicated in Section 2 Unit Specifications and
Components. Failure to adhere to the specifications may result in fire. In places
where power supply conditions are poor, take steps to ensure that power is sup-
plied at the rated voltage. Be sure to adhere to safety precautions, such as pro-
viding breakers to prevent short circuits in external wiring. When conducting any
of the following operations, turn OFF the power to the PC. Electric shock, prod-
uct damage and malfunction may result.
•Connecting or disconnecting Expansion I/O Units and CPU Units.
•Assembling Units
•Connecting cables and wiring.
3-1-4 CPM1A Power Interruptions
Supply Voltage Drop
When the supply voltage falls below 85% of the rated value, the PC will stop and
the outputs will go OFF.
Design Precautions Section 3-1
!
37
Momentary Power Failure Detection
A momentary power failure lasting less than 10 ms with an AC power supply and
2 ms with a DC power supply is not detected and the CPU Unit continues to oper-
ate.
A momentary power failure lasting longer than 10 ms with an AC power supply
and 2 ms with a DC power supply may or may not be detected in an uncertain
area.
When a momentary power failure is detected, the CPU Unit stops operating and
the output goes OFF.
Automatic Restart
When the supply voltage recovers to a value higher than 85% of the rated value,
operations resumes automatically.
Duration of power interrupt
(Below 85% of rated voltage)
10 ms (2 ms)
Under Over
Normal operation Operation may stop.
All outputs go OFF when
operations stop.
Note The CPM1A may repeat stop/start operations if the supply voltage of less than
85% of the rated value gradually goes up or down.
If this affects the equipment, etc., provide a protection circuit which shuts off the
output if the supply voltage is not above the rated value.
Time Up to the Start of Operation
The time from when the power supply is turned on to when the operation starts
varies depending on the operation conditions such as power supply voltage,
configuration, ambient temperature, etc. The minimum time is approximately
300 ms.
3-2 Selecting an Installation Site
The CPM1A is resistant to harsh conditions and highly reliable, but installing the
PC in a favorable site will maximize its reliability and operating lifetime.
Caution Be sure to install the CPM1A correctly, as outlined in this manual. Failure to do so
may result in Unit malfunction.
3-2-1 Installation Site Conditions
Note Do not install the CPM1A under any of the following conditions.
•Locations subject to direct sunlight.
•Locations subject to a temperature below 0°C or over 55°C.
•Locations subject to a humidity below 10% or over 90%.
•Locations subject to condensation as the result of severe changes in tempera-
ture.
•Locations subject to corrosive or flammable gases.
•Locations subject to dust (especially iron dust) or salts.
•Locations subject to shock or vibration.
•Locations subject to exposure to water, oil, or chemicals.
Be sure that the conditions at the installation site conform to the CPM1A’s gen-
eral specifications. Refer to 2-1-1 General Specifications for details.

38
Note Provide proper shielding when installing in the following locations:
•Locations subject to static electricity or other sources of noise.
•Locations subject to strong electromagnetic fields.
•Locations subject to possible exposure to radiation.
•Locations near to power supply lines.
3-2-2 Panel/Cabinet Installation
Consider PC operation, maintenance, and surrounding conditions when instal-
ling the CPM1A in a panel or cabinet.
Overheating The operating temperature range for the CPM1A is 0C to 55C. Be sure that
there is adequate ventilation for cooling.
•Allow enough space for air circulation.
•Do not install the CPM1A above equipment that generates a large amount of
heat, such as heaters, transformers, or large resistors.
•Install a cooling fan or system when the ambient temperature exceeds 55C.

Caution Disconnect the functional earth terminal when performing withstand voltage
tests. Not disconnecting the functional earth terminal may result in burning.
Crimp Connectors
Caution Always use crimp connectors for the CPM1A’s power lines and I/O lines or else
use a solid wire (instead of a stranded wire). Do not connect bare stranded wires
directly to terminals. Bare stranded wires connected directly to the terminal can
cause a fire.
Use M3 terminal screws and tighten the screws securely (0.5 N m).

The recommended wire size for solid wires is 0.4 to 1.2 mm (AWG26 to AWG18).
3-4-3 Power Supply Wiring
Wire a separate circuit for the CPM1A’s power supply circuit so that there isn’t a
voltage drop from the inrush current that flows when other equipment is turned
on.
When several CPM1A PCs are being used, it is recommended to wire the PCs
on separate circuits to prevent a voltage drop from the inrush current or incorrect
operation of the circuit breaker.
Use twisted power supply wires to prevent noise from the power supply lines.
Adding a 1:1 isolating transformer reduces electrical noise even further.
Considering the possibility of voltage drops and the allowable current, be sure to
use thick power lines.

Note 1. Before connecting the power supply, make sure that the CPU Unit requires
an AC power supply and not a DC power supply. The CPU Unit’s internal
circuitry will be damaged if AC power is mistakenly supplied to a CPU Unit
that requires a DC power supply.
2. The power supply input terminals are at the top of the CPU Unit; the termi-
nals at the bottom of the CPU Unit output 24-VDC power for external de-
vices. The CPU Unit’s internal circuitry will be damaged if AC power is mis-
takenly supplied to a CPU Unit’s power supply output terminals.

Leakage Current (24 VDC) A leakage current can cause false inputs when using 2-wire sensors (proximity
switches or photoelectric switches) or limit switches with LEDs.
False inputs won’t occur if the leakage current is less than 1.0 mA (2.5 mA for
IN00000 to IN00002), but if the leakage current exceeds these values, insert a
bleeder resistor in the circuit to reduce the input impedance, as shown in the fol-
lowing diagram.

Caution Double-check the polarity of the power supply for the load before turning it on.
Output Wiring Precautions Observe the following precautions to protect the PC’s internal components.
Output Short Protection
The output or internal circuitry might be damaged when the load connected to an
output is short-circuited, so it is recommended to install a protective fuse (0.5 to
1.0 A) in each output circuit.
Polarity of Power Supply for the Load
Double-check the polarity of the DC power supply for the load before wiring the
transistor output. If the polarity of the power supply is reversely connected, the
load will malfunction and internal components may be damaged.

3-4-10 CompoBus/S I/O Link Connections
A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input
points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The
connection is made through a CompoBus/S I/O Link Unit.
From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-
Bus/S I/O Link Unit can be treated just like the area allocated to an Expansion I/O
Unit. The difference is that the bits are not actual I/O points, but I/O bits in the
Master Unit.

4-1 Support Software Capabilities
The SSS is a complete programming and control package designed for C-series
and CVM1 PCs. It provides not only programming capabilities, but also
advanced debugging, monitoring, and program/data management. The follow-
ing tables provide only a brief introduction to the capabilities of the SSS. For fur-
ther information and actual operating procedures, please refer to the SYSMAC
Support Software Operation Manuals: Basics and C-series.
CPM1A programming can be performed with any version of the SSS.
In addition, the SYSMAC-CPT can be used for programming the CPM1A. Refer
to the SYSMAC-CPT Support Software Quick Start Guide (W332) and User
Manual (W333) for operation procedures. When programming the CPM1A
using the SYSMAC-CPT, be sure to set the “PC model” on the Support Software
to “CPM1 (CPM1A).”
Operations for the WS02-CXPC1-E CX-Programmer are provided in the
WS02-CXPC1-E CX-Programmer User Manual (W361) and the CX-Server
User Manual (W362).
4-1-1 SSS System Setup
Set the PC Model to “CQM1” and the PC Interface to “PERIPHERAL.” Follow the
directions in the SSS operating manuals for other System Setup settings.
PC Model If the CPM1A PC doesn’t appear as an option in the SSS’s System Setup, set the
PC Model to “CQM1.” The CPM1A is compatible with the CQM1.
PC Interface Set the PC Interface to the Peripheral Device Port by selecting “PERIPHERAL”
from the submenu. After selecting the Peripheral Device Port, set the commu-
nications baud rate to 9,600 baud.
4-1-2 CPM1A Restrictions and Precautions
When programming the CPM1A, set the PC Model on the SSS to “CQM1.” Heed
the following restrictions when programming the CPM1A.
Programming Check Since the data area of the CQM1 is larger than that of the CPM1A, some parts of
the area cannot be checked as the CPM1A PC. Pay careful attention to the
usable data area when programming.
Note If a program that contains addresses not supported by the CPM1A are trans-
ferred to the CPM1A, a memory error will occur when operation is begun and
AR 1308 will turn ON. Refer to the Programming Manual (W353) for differences
in memory areas.
Memory Usage Since the memory of the the CQM1 is larger than that of the CPM1A, the dis-
played available memory capacity is larger than the actual available memory
capacity. Pay careful attention to the actual available memory capacity when
programming.
Expansion Instructions When a program is transferred after changing the assignment of function codes
for the 18 expansion instructions, a message to “Turn on the DIP switch of the
PC and execute again” is displayed. Change the assignment of the function
codes for the expansion instructions to the default settings before programming.
The default settings for the CQM1 are as shown in the following table.

This is the CPM1A’s normal operating mode. The CPM1A’s operating status can
be monitored from a Programming Device, but bits can’t be force-set/force-reset
and the SV/PV of timers and counters can’t be changed.
Caution Check the system thoroughly before changing the operating mode of the PC to
prevent any accidents that might occur when the program is first started.
Caution Never change the mode while pressing any of the keys.

4-2-4 Preparation for Operation
This section describes the procedures required to begin Programming Console
operation when using the Programming Console for the first time.
Caution Always confirm that the Programming Console is in PROGRAM mode when
turning ON the PC with a Programming Console connected unless another
mode is desired for a specific purpose. If the Programming Console is in RUN
mode when PC power is turned ON, any program in Program Memory will be
executed, possibly causing a PC-controlled system to begin operation.
The following sequence of operations must be performed before beginning ini-
tial program input.
1, 2, 3... 1. Be sure that the PC is OFF.
2. Connect the Programming Console to the CPU Unit’s peripheral port. See
4-2-3 Connecting the Programming Console for details.
(The CPU Unit’s Communications Switch setting has no effect on commu-
nications with the Programming Console.)
3. Set the mode switch to PROGRAM mode.
4. Turn ON the PC.
5. Enter the password. See 4-2-5 Entering the Password for details.
6. Clear (All Clear) the PC’s memory. See 4-3-2 Clearing Memory for details.
7. Read and clear all errors and messages. See 4-3-3 Reading/Clearing Error
Messages for details.
8. Start programming.
4-2-5 Entering the Password
To gain access to the PC’s programming functions, you must first enter the pass-
word. The password prevents unauthorized access to the program.
The PC prompts you for a password when PC power is turned on or, if PC power
is already on, after the Programming Console has been connected to the PC. To
gain access to the system when the “Password!” message appears, press CLR
and then MONTR. Then press CLR to clear the display.

5-1 Initial System Checks and Test Run Procedure
5-1-1 Initial System Checks
Note Check the following items after setting up and wiring the CPM1A. Be sure to
check the wiring and connections before performing a test run.
Item Points to check
Power supply and
I/O connections Is the wiring correct?
Are the terminals securely tightened?
Are there any shorts between crimp connectors or wires?
Refer to 3-4 Wiring and Connections for details.
Connecting cables Are the cables all connected correctly and locked?
Refer to 3-4 Wiring and Connections for details.
Dustproof label Has the dustproof label been removed?
Note 1. Always clear memory before beginning to program the CPM1A. Although
memory is cleared before the CPU Unit is shipped (except for bits with spe-
cific functions), AR 1314, which turns ON when the internal capacitor cannot
back up memory, may have turned ON during shipment.
2. If the CPM1A will be turned off for periods exceeding the data backup period
of the internal capacitor, design the system so that it will not be influenced if
data in the DM, HR, and CNT areas is cleared when power is turned off.
3. Either switch the CPM1A to RUN or MONITOR mode, or turn off and on
power to the CPM1A after changing from a Programming Device any data
that is backed up in flash memory. This data includes the user program,
read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to
DM 6655).
5-1-2 CPM1A Test Run Procedure
1, 2, 3... 1. Power Supply Application
a) Check the CPM1A’s power supply voltage and terminal connections.
b) Check the I/O devices’ power supply voltage and terminal connections.
c) Turn on the power supply and check that the “PWR” indicator lights.
d) Use a Peripheral Device to set the CPM1A to PROGRAM mode.
2. I/O Wiring Checks
a) With the CPM1A in PROGRAM mode, check the output wiring by turning
on the output bits with the force set and force reset operations.
Refer to 4-3-23 Force Set, Reset for details.
b) Check the input wiring with the CPM1A’s input indicators or a Peripheral
Device’s monitor operations.
3. Test Run
a) Use a Peripheral Device to set the CPM1A to RUN or MONITOR mode
and check that the “RUN” indicator lights.
b) Check the sequence of operation with the force set/reset operations, etc.
4. Debugging
Correct any programming errors that are detected.
5. Saving the Program
a) Use a Peripheral Device to write the program to a backup floppy disk.
b) Print out a hard copy of the program with a printer.
Note Refer to Section 4 Using Peripheral Devices for details on SYSMAC Support
Software or Programming Console operations.
Initial System Checks and Test Run Procedure Section 5-1
111
5-1-3 Flash Memory Precautions
Observe the following precautions to protect the flash memory and ensure
proper operation.
1, 2, 3... 1. If the power is turned off without changing the mode after having made chan-
ges in the read-only DM area (DM 6144 through DM 6599), or PC Setup (DM
6600 through DM 6655), the contents of changes will not be written to flash
memory. Therefore, if the power is turned off for more than 20 days (at
25C), contents of changes (contents of the RAM) will disappear and the
data values will become undefined values. For details, refer to 2-1-2 Char-
acteristics.
The changes can be saved by switching the CPM1A to RUN or MONITOR
mode or turning on the CPM1A soon after the changes are made.
2. When the CPM1A is operated for the first time after changing the program,
the read-only DM area (DM 6144 through DM 6599) or PC Setup (DM 6600
through DM 6655) will take about 600 ms longer than usual. Be sure to take
this one-time startup delay into account.
3. If one of the following three operations is performed in MONITOR or RUN
mode, the CPM1A will extend the cycle time for up to 600 ms and interrupts
will be disabled while the program or PC Setup is being overwritten.
•Program changes with the online edit operation
•Changes to the read-only DM area (DM 6144 through DM 6599)
•Changes to the PC Setup (DM 6600 through DM 6655)
A “SCAN TIME OVER” error won’t occur during these operations. The
CPM1A’s I/O response times may be affected when the online edit operation
is being performed.
Initial System Checks and Test Run Procedure Section 5-1
112
5-2 The CPM1A Cycle
The overall flow of CPM1A operation is as shown in the following flowchart. The
CPM1A is initialized internally when the power is turned on. If no errors are
detected, the overseeing processes, program execution, I/O refreshing, and
Peripheral Device servicing are executed consecutively (cyclically). The aver-
age cycle time can be monitor from a Peripheral Device.

113
5-3 Self-diagnosis Functions
The CPM1A is equipped with a variety of self-diagnosis functions to help identify
and correct errors that might occur and reduce down time.
PC errors are divided into 2 categories based on the severity of the errors. Fatal
errors are more serious errors which stop CPM1A operation. Non-fatal errors
are less serious and don’t stop CPM1A operation.
5-3-1 Non-fatal Errors
PC operation and program execution will continue after one or more of these
errors have occurred. Although PC operation will continue, the cause of the error
should be corrected and the error cleared as soon as possible.
When one of these errors occurs, the POWER and RUN indicators will remain lit
and the ERR/ALM indicator will flash.
Message FAL No. Meaning and appropriate response
SYS FAIL FAL**
(** is 01 to 99 or 9B.) 01 to 99 An FAL(06) instruction has been executed in the program. Check the FAL number to
determine conditions that would cause execution, correct the cause, and clear the
error.
9B An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and
correct as directed.
AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to
DM 6614) when power was turned on. Correct the settings in PROGRAM Mode and
turn on the power again.
AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to
DM 6644) when switching to RUN Mode. Correct the settings in PROGRAM Mode
and switch to RUN Mode again.
AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to
DM 6655) during operation. Correct the settings and clear the error.
SCAN TIME OVER F8 Watchdog timer has exceeded 100 ms. (SR 25309 will be ON.)
This indicates that the program cycle time is longer than recommended. Reduce cycle
time if possible. (The CPM1A can be set so that this error won’t be detected.)
Communication
Errors (no message) None If an error occurs in communications through the peripheral port, the COMM indicator
will be off. Check the connecting cables and restart. Check the error flags in AR 0812
ON.
5-3-2 Fatal Errors
PC operation and program execution will stop and all outputs from the PC will be
turned OFF when any of these errors have occurred. CPM1A operation can’t be
restarted until the PC is turned off and then on again or a Peripheral Device is
used to switch the PC to PROGRAM mode and clear the fatal error.
All CPU Unit indicators will be OFF for the power interruption error. For all other
fatal operating errors, the POWER and ERR/ALM indicators will be lit. The RUN
indicator will be OFF.
WARNING The PC will turn OFF all outputs when its self-diagnosis function detects any
error or when a severe failure alarm (FALS) instruction is executed. External
safety measures must be provided to ensure safety in the system. Not providing
proper safety measures may result in serious accidents.
Self-diagnosis Functions Section 5-3
114
Message FALS
No. Meaning and appropriate response
Power interruption
(no message) None Power has been interrupted for at least 10 ms (2 ms for DC power types.) Check
power supply voltage and power lines. Try to power-up again.
MEMORY ERR F1 AR 1308 ON: An unspecified bit area exists in the user program. Check the program
and correct errors.
AR 1309 ON: An error has occurred in reading or writing flash memory. Replace the
CPU Unit.
AR 1310 ON: A checksum error has occurred in read-only DM (DM 6144 to DM 6599).
Check and correct the settings in the read-only DM area.
AR 1311 ON: A checksum error has occurred in the PC Setup. Initialize all of the PC
Setup and reinput.
AR 1312 ON: A checksum error has occurred in the program. Check the program and
correct any errors detected.
AR 1314 ON: The internal capacitor can no longer back up data. Clear the error and
check/correct the contents of the data areas backed up by the capacitor.
NO END INST F0 END(01) is not written in the program. Write END(01) at the end of the program.
I/O BUS ERR C0 An error has occurred during data transfer between the CPU Unit and Expansion I/O
Unit. Check the Expansion I/O Unit’s connecting cable.
I/O UNIT OVER E1 Too many I/O Units have been connected. Check the I/O Unit configuration.
SYS FAIL FALS**
(** is 01 to 99 or 9F.) 01 to 99 A FALS(07) instruction has been executed in the program. Check the FALS number to
determine the conditions that caused execution, correct the cause, and clear the error.
9F The cycle time has exceeded the FALS 9F Cycle Time Monitoring Time (DM 6618).
Check the cycle time and adjust the Cycle Time Monitoring Time if necessary.
5-3-3 Identifying Errors
PC errors can be identified from error messages displayed on the Programming
Console, error flags in the SR or AR areas, and the error code in SR 25300 to
SR 25307.
Error Messages Error messages generated by the self-diagnosis function can be read from a
Programming Console or host computer running SYSMAC Support Software.
Error Flags When the self-diagnosis function detects a hardware error, it will turn on the cor-
responding error flags in the SR and AR areas.
Error Code When an error is detected by the self-diagnosis function, the corresponding
error code is written to SR 25300 to SR 25307. (The error code is an 2-digit hex-
adecimal code.)
5-3-4 User-defined Errors
There are three instructions that the user can use to define his own errors or
messages. FAL(06) causes a non-fatal error, FAL(07) causes a fatal error, and
MSG(46) sends a message to the Programming Console or host computer con-
nected to the PC.
FAILURE ALARM – FAL(06) FAL(06) is an instruction that causes a non-fatal error. The following will occur
when an FAL(06) instruction is executed:
1, 2, 3... 1. The ERR/ALM indicator on the CPU Unit will flash. PC operation will con-
tinue.
2. The instruction’s 2-digit BCD FAL number (01 to 99) will be written to
SR 25300 to SR 25307.
The FAL numbers can be set arbitrarily to indicate particular conditions. The
same number cannot be used as both an FAL number and an FALS number.
To clear an FAL error, correct the cause of the error and then execute FAL 00 or
clear the error using the Programming Console.
Self-diagnosis Functions Section 5-3
115
FALS(07) is an instruction that causes a fatal error. The following will occur when
an FALS(07) instruction is executed:
1, 2, 3... 1. Program execution will be stopped and outputs will be turned OFF.
2. The ERR/ALM indicator on the CPU Unit will be lit.
3. The instruction’s 2-digit BCD FALS number (01 to 99) will be written to
SR 25300 to SR 25307.
4. The FALS number and time of occurrence will be recorded in the PC’s error
log area if a Memory Cassette with a clock (RTC) is used.
The FALS numbers can be set arbitrarily to indicate particular conditions. The
same number cannot be used as both an FAL number and an FALS number.
To clear an FALS error, switch the PC to PROGRAM Mode, correct the cause of
the error, and then clear the error using the Programming Console.
MESSAGE – MSG(46) MSG(46) is used to display a message on the Programming Console. The mes-
sage, which can be up to 16 characters long, is displayed when the instruction’s
execution condition is ON.
5-4 Programming Console Operation Errors
The following error messages may appear when performing operations on the
Programming Console. Correct the error as indicated and continue with the
operation. Refer to the SYSMAC Support Software Operation Manuals: Basics
and C-series PCs for errors that may appear when operating the SSS.
Message Meaning and appropriate response
REPL ROM An attempt was made to write to write-protected memory. Set bits
00 to 03 of DM 6602 to “0.”
PROG OVER The instruction at the last address in memory is not NOP(00). Erase
all unnecessary instructions at the end of the program.
ADDR OVER An address was set that is larger than the highest memory address
in Program Memory. Input a smaller address.
SETDATA
ERR FALS 00 has been input, and “00” cannot be input. Reinput the
data.
I/O NO. ERR A data area address has been designated that exceeds the limit of
the data area, e.g., an address is too large. Confirm the
requirements for the instruction and re-enter the address.
5-5 Programming Errors
These errors in program syntax will be detected when the program is checked
using the Program Check operation.
SEVERE FAILURE ALARM –
FALS(07)
Programming Errors Section 5-5
116
Three levels of program checking are available. The desired level must be des-
ignated to indicate the type of errors that are to be detected. The following table
provides the error types, displays, and explanations of all syntax errors. Check
level 0 checks for type A, B, and C errors; check level 1, for type A and B errors;
and check level 2, for type A errors only.

program so that each IL(02) has a unique ILC(03).
Although this error message will appear if more than one
IL(02) is used with the same ILC(03), the program will
executed as written. Make sure your program is written as
desired before proceeding.
JMP-JME ERR JMP(04) and JME(05) are not used in pairs. Make sure
your program is written as desired before proceeding.
SBN-RET ERR If the displayed address is that of SBN(92), two different
subroutines have been defined with the same subroutine
number. Change one of the subroutine numbers or delete
one of the subroutines. If the displayed address is that of
RET(93), RET(93) has not been used properly. Check
requirements for RET(93) and correct the program.
CCOIL DUPL The same bit is being controlled (i.e., turned ON and/or
OFF) by more than one instruction (e.g., OUT, OUT NOT,
DIFU(13), DIFD(14), KEEP(11), SFT(10)). Although this is
allowed for certain instructions, check instruction
requirements to confirm that the program is correct or
rewrite the program so that each bit is controlled by only
one instruction.
JMP UNDEFD JME(05) has been used with no JMP(04) with the same
jump number. Add a JMP(04) with the same number or
delete the JME(05) that is not being used.
SBS UNDEFD A subroutine exists that is not called by SBS(91). Program
a subroutine call in the proper place, or delete the
subroutine if it is not required.

5-7 Maintenance Inspections
In order that your SYSMAC system operates in optimum condition, be sure to
carry out daily or periodical inspections.
Inspection Items The main system components of a SYSMAC system are semiconductors, and it
contains few components with limited lifetimes. Environmental conditions, how-
ever, can lead to electrical element deterioration, making regular maintenance
necessary.
The standard period for maintenance checks is 6 months to 1 year, but depend-
ing on the environment checks may need to be more regular.
If the criteria are not met, adjust to within the specified ranges.

ate outputs to external devices according to a program held in memory. Pro-
grammable Controllers are used to automate control of external devices.
Although single-unit Programmable Controllers are available, building-block
Programmable Controllers are constructed from separate components. Such
Programmable Controllers are formed only when enough of these separate
components are assembled to form a functional assembly.

an incrementing counter counts up (i.e., the maximum count), or the time from
which or for which a timer starts timing. Set value is abbreviated SV.
shift input signal An input signal whose OFF to ON transition causes data to be shifted one bit.
shift register One or more words in which data is shifted a specified number of units to the right
or left in bit, digit, or word units. In a rotate register, data shifted out one end is
shifted back into the other end. In other shift registers, new data (either specified
data, zero(s) or one(s)) is shifted into one end and the data shifted out at the
other end is lost.
