7Safety Precautions
WARNING It is extremely important that a PC and all PC Units be used for the specified
!
purpose and under the specified conditions, especially in applications that can
directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PC System to the above-mentioned
applications.
3 Safety Precautions
WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing so
!
may result in electric shock.
WARNING Do not touch any of the terminals or terminal blocks while the power is being
!
supplied. Doing so may result in electric shock.
WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so
!
may result in malfunction, fire, or electric shock.
WARNING Provide safety measures in external circuits (i.e., not in the Programmable
!
Controller), including the following items, in order 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 doing so may result in serious accidents.
xvi
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
• 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. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.
• The PC outputs may remain ON or OFF due to deposition or burning of the
output relays or destruction of the output transistors. As a countermeasure for
such problems, external safety measures must be provided to ensure safety in
the system.
• When the 24-VDC output (service power supply to the PC) is overloaded or
short-circuited, the voltage may drop and result in the outputs being turned
OFF. As a countermeasure for such problems, external safety measures must
be provided to ensure safety in the system.
WARNING When transferring programs to other nodes, or when making changes to I/O
!
memory, confirm the safety of the destination node before transfer. Not doing so
may result in injury.
Caution Execute online edit only after confirming that no adverse effects will be caused
!
by extending the cycle time. Otherwise, the input signals may not be readable.
Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the
!
torque specified in the operation manual. The loose screws may result in burning
or malfunction.
4Operating Environment Precautions
Caution When connecting a personal computer or other peripheral device to the CPM1A,
!
either ground the 0 V side of the CPM1A or do not ground at all. Depending on
the method of grounding, the 24-V power supply may short-circuit; do not
ground the 24-V side as shown in the following diagram.
Example: Connections where 24-V Power Supply Will Short-circuit
Non-isolated DC
power supply

4 Operating Environment Precautions
Caution Do not operate the control system in the following places:
!
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified in
the specifications.
• 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 exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
Caution Take appropriate and sufficient countermeasures when installing systems in the
!
following locations:
xvii
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
Caution The operating environment of the PC System can have a large effect on the lon-
!
gevity and reliability of the system. Improper operating environments can lead to
malfunction, failure, and other unforeseeable problems with the PC System. Be
sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.
5 Application Precautions
Observe the following precautions when using the PC System.
WARNING Always heed these precautions. Failure to abide by the following precautions
!
could lead to serious or possibly fatal injury.
• Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground of 100 Ω or less may result in electric shock.
• Always turn off the power supply to the PC before attempting any of the following. 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.
5Application Precautions
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 precautions.
• 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 temporarily 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 instructions), 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-circuiting in external wiring. Insufficient safety measures against short-circuiting may
result in burning.
xviii
5Application Precautions
• 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 installation 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.
• With version-1 CPU Units, leave the label attached wiring in order to prevent
wiring cuttings from entering in the Unit.
• With pre-version-1 CPU Units, be sure to attach the supplied labels when wiring in order to prevent wiring cuttings from entering in the Unit.
• Remove the label after the completion of wiring to ensure proper heat dissipation. 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 wiring may result in burning.
• Be sure that the terminal blocks, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.
• 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 correctly.
xix
• 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).
• 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
Flash memory User program
DM 1023)
Error log area (DM 1000 to DM 1021)
HR area (HR 00 to HR 19)
Counter area (CNT 000 to CNT 127)
Read-only DM area (DM 6144 to DM 6599)
PC Setup (DM 6600 to DM 6655)
5Application Precautions
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 according 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 continuously for at least 15 minutes.
20

Ambient temperature (C)
xx
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.
6 EC Directives
6-1 Applicable Directives
• EMC Directives
• Low Voltage Directive
6EC Directives
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 standards 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 Directives will vary depending on the configuration, wiring, and other conditions of the
equipment or control panel on which the OMRON devices are installed. The customer 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): EN61000-6-4
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to
1,500 VDC meet the required safety standards for the PC (EN61131-2).
6-3 Conformance to EC Directives
All CPM1A CPU Units with model numbers ending in “-V1” conform to EC directives.
The following restrictions apply to CPM1A CPU Units with model numbers not
ending in “-V1.”
• Relay Output Units and Transistor Output Units of CPU Units with DC power
supplies conform to EC Directives. Relay Output Units, however, conform to
EC Directives only when the output load power supply is outside the ranges
specified for the Low Voltage Directive (less than 75 VDC or less than 50 VAC).
• Relay Output Units and Transistor Output Units of CPM1A CPU Units with AC
power supplies do not conform to EC Directives.
(Radiated emission: 10-m regulations)
xxi
All Expansion I/O Units except for the CPM1A-20EDR conform to 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 PC and I/O power supplies.
3. CPM1A PCs complying with EC Directives also conform to the Common
Emission Standard (EN61000-6-4). 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
conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives.
6-4 Relay Output Noise Reduction Methods
All CPM1A CPU Units with model numbers ending in “-V1” conform to the Common Emission Standards (EN61000-6-4) of the EMC Directives.
For CPM1A CPU Units with model numbers not ending in “-V1,” Relay Output
Units and Transistor Output Units of CPU Units with DC power supplies conform
to the Common Emission Standards (EN61000-6-4) of the EMC Directives.
Relay Output Units, however, conform to the Common Emission Standards
(EN61000-6-4) only when the output load power supply is outside the ranges
specified for the Low Voltage Directive (less than 75 VDC or less than 50 VAC).
6EC Directives
When a Unit is built into another device, however, it may not satisfy these standards due to noise generated by relay output switching. In such a case, a noise
filter must be connected to the load side or other appropriate countermeasures
must be provided external to the PC.
Countermeasures taken to satisfy the standards vary depending on the devices
on the load side, wiring, configuration of machines, etc. Following are examples
of countermeasures for reducing the generated noise.
Countermeasures
Refer to EN50081-2 for more details.
Countermeasures are not required if the frequency of load switching for the
whole system including the PC is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system including the PC is more than 5 times per minute.
Countermeasure Examples
When switching an inductive load, connect a surge protector, diodes, etc., in parallel with the load or contact. For detailed circuit examples, refer to the relevant
parts of this manual.

Immunity testing conditions when using the current I/O of the CPM1A-MAD01
are as follows.
• Total accuracy: +10%/-1%
• Insert the following core in each line as shown below.

CPM1A Features and Functions Section 1-1
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, sinking transistor output models, and sourcing transistor output
models.
CPU Units with 10 I/O Points
CPM1A-10CD--V1 CPM1A-10CD-
CPU Units with 30 I/O Points
CPM1A-30CD--V1 CPM1A-30CD-
CPU Units with 40 I/O Points
CPM1A-40CD--V1 CPM1A-40CD-
CPU Units with 20 I/O Points
CPM1A-20CD--V1 CPM1A-20CD-
Extra I/O Capacity Up to three Expansion I/O Units can be connected to a CPM1A-30CD-(-V1)
or CPM1A-40CD-(-V1) 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-10CD-(-V1) CPU Units can handle 2 interrupt inputs; the
CPM1A-20CD-(-V1), CPM1A-30CD-(-V1), and CPM1A-40CD-
(-V1) 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.
2
CPM1A Features and Functions Section 1-1
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 interrupts 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.
Analog I/O Units
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 analog inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O
Units.

Pt100: –200.0° to 650.0°C (–300.0° to 1,200.0°F)
JPt100: –200.0° to 650.0°C (–300.0° to 1,200.0°F)
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 communicate 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/HG/HE 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.
CompoBus/S I/O Link
Units
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 (internal) and 8 output bits (internal).
3
CPM1A Features and Functions Section 1-1
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.
CompoBus/S Master Unit

DeviceNet I/O Link Units DeviceNet I/O Link Units can be connected to enable using the CPM1A as a De-
viceNet slave. Up to 32 internal input and 32 internal outputs points are supported for each Unit, and up to 3 Units can connected. DeviceNet application
allows networks to be constructed including devices from other manufacturers.

1-1-3 CPM1A Functions
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.

CPM1A Features and Functions Section 1-1
The following table shows which IR words are allocated to the analog adjustments on the CPM1A’s CPU Unit.
Control Corresponding IR word Setting range (BCD)
Analog adjustment 0 IR 250
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.

Input time constant
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
4 ms 4 to 4.5 ms 1.5 to 2.5 ms
8 ms 8 to 8.5 ms 3 to 4.5 ms
16 ms 16 to 16.5 ms 6 to 9 ms
32 ms 32 to 32.5 ms 12 to 18 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-(-V1)/10CDT-D(-V1)/10CDT1-D(-V1) PCs have 2 inter-
rupt input terminals and the CPM1A-20CDR-(-V1)/20CDT-
D(-V1)/20CDT1-D(-V1), CPM1A-30CDR-(-V1)/ 30CDT-D/30CDT1-D(-V1),
and CPM1A-40CDR-(-V1)/40CDT-D(-V1)/40CDT1-D(-V1) PCs have 4 inter-
rupt input terminals. There are two modes for input interrupts: input interrupt
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.

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 frequently, 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 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

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.

CPM1A Features and Functions Section 1-1
The pulse output can be set to either the continuous mode, under which the output can be stopped by an instruction, or the single mode, under which the output
can be stopped by the preset pulse rate (1 to 16,777,215).

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
Flash memory User program

Error log area (DM 1000 to DM 1021)
HR area (HR 00 to HR 19)
Counter area (CNT 000 to CNT 127)
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 according 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 continuously for at least 15 minutes.

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.
Specifications Section 2-1
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.
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).

Design Precautions Section 3-1
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 systems such as position control.
The following diagram shows an example of an interlock circuit.
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 supplied at the rated voltage. Be sure to adhere to safety precautions, such as providing breakers to prevent short circuits in external wiring. When conducting any
of the following operations, turn OFF the power to the PC. Electric shock, product 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.
42
Selecting an Installation Site
Section 3-2
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 operate.
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)
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.
Under Over
Normal operation Operation may stop.
10 ms (2 ms)
All outputs go OFF when
operations stop.
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 general specifications. Refer to 2-1-1 General Specifications for details.
43
Selecting an Installation Site
Section 3-2
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 installing 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.
Control panel
Air vent

CPM1A
Electrical Noise Power lines and high-voltage equipment can cause electrical noise in the PC.
• Do not install the CPM1A in a panel or cabinet with high-voltage equipment.
• Allow at least 200 mm between the CPM1A and nearby power lines.
200 mm min.

Accessibility Ensure that the CPM1A can be accessed for normal operation and mainte-
nance.
• Provide a clear path to the CPM1A for operation and maintenance. High-volt-
age equipment or power lines could be dangerous if they are in the way during
routine operations.
• The PC will be easiest to access if the panel or cabinet is installed about 3 to 5
feet off of the floor.

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 following diagram.

Sensor Surge Current If a sensor power supply is turned ON when the PC is ON and ready to receive
inputs, surge current from the sensor may result in an incorrect input. To prevent
improper operation, use the following type of programming in the ladder program to delay accepting inputs from a sensor from when the sensor is turned ON
until the sensor reaches stable operation.

Note The SV of TIM 000 can be set to #0001 (0.1 s) to achieve a delay time of 100 ms,
but the timer accuracy is 0 to 0.1 s, meaning that the timer’s Completion Flag
may turn ON immediately after the timer input. The SV must thus be set to #0002

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.

Wiring and Connections
3-4-10 CompoBus/S I/O Link Unit Connections
A CompoBus/S I/O Link Unit 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 CompoBus/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.
