factor affecting the PC operation. Not doing so may result in serious accidents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
xvii
Safety Precautions 3
• 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.
• If the 24-VDC output (service power supply) of the Power Supply Unit
(CPM2C-PA201) is overloaded or shorted, the voltage may drop causing
outputs to turn OFF. External safety measures must be provided to
ensure safety in the system in such an event.
!WARNING When handling the Memory Backup Battery, never drop, disassemble, distort,
short-circuit, recharge, heat to a temperature exceeding 100
°C, or throw into
fire. Otherwise the Battery may explode, catch fire, or leak fluid.
!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 Power Supply Unit (CPM2C-
PA201) to a torque of 0.74 to 0.9 N•m. Loose screws may result in burning or
malfunction.
!Caution Do not connect the 24-VDC output (service power supply) or the Power Sup-
ply Unit (CPM2C-PA201) to an AC power supply. Connecting it to an AC
power supply will damage the internal circuit.
!Caution When connecting a personal computer or other peripheral device to the
CPM2C, either ground the 0 V side of the CPM2C 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.

!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 such that the grounding resistance does not
exceed 100
Ω when installing the Units. Not connecting to the correct
ground 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.
• Assembling the Units.
• Connecting or disconnecting the Expansion I/O Units or Expansion
Units.
• Connecting or wiring the cables.
• Connecting or disconnecting the connectors.
• Setting DIP switches.
• Replacing the battery
xix
Application Precautions 5
!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.
• Use the correct power supply voltage.
• 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.)
• For models with only the super-capacitor installed, the contents of the
READ/WRITE enable area of the DM area, HR area, AR area, and CNT
data area may be damaged if the power is turned OFF for a long time. To
prevent such damage, provide ladder program that will check AR 1314 in
order to ensure proper operation of the system.
• The life expectancy of the output relay varies considerably according to its
switching capacity and switching conditions. If the output relay is used
beyond its life expectancy, its contacts may become fused or burned.
• Install the Units properly so that they will not fall off.
• 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 that the terminal blocks and other items with locking devices are
properly locked into place. Improper locking may result in malfunction.
• Be sure that terminal blocks and connectors are connected in the specified direction with the correct polarity. Not doing so may result in malfunction. If the power supply for the I/O circuits is turned ON with the input and
output connectors reversed, the fuse of output transistor may be blown.
• Use the Unit with the battery housing cover in place to prevent dust or foreign matter from entering inside the Unit. Not doing so may result in malfunction.
• Install the expansion I/O connector cover to the last Unit (Expansion Unit
or Expansion I/O Unit) to prevent dust or foreign matter from entering
inside the Unit. Not doing so may result in malfunction.
• Be sure to attach the labels supplied with the CPM2C or provide other
protective covers when wiring in order to prevent dust or wiring cuttings
from entering the Unit.
• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
• Use round crimp terminals for wiring the AC power supply input to the AC
Power Supply Unit (CPM2C-PA201). For wiring the ground terminals or
power supply service terminals, use crimp terminals or solid wires. Do not
connect bare stranded wires directly to terminals. Connection of bare
stranded wires may result in burning.
xx
Application Precautions 5
• Be sure to perform wiring in accordance with the CPM2C Operation Manual. Incorrect wiring may result in burning.
• Use specified connectors and wiring materials (connector models: C500CE241/C500-CE242/C500-CE243; terminal block models: AWG28-16
with stripped length of 7 mm; Power Supply Unit terminal block: AWG2214 with stripped length of 7 mm).
• Do not apply voltages to the input terminals in excess of the rated input
voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the output terminals in excess
of the maximum switching capacity. Excess voltage or loads may result in
burning.
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.
• Always use the power supply voltage specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected operation.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring or switch settings may result in burning.
• 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.
• 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 pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.
• Do not apply forces exceeding 50 N to connector sections.
• Do not place objects on top of the cables. Doing so may break the cables.
• 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.
• Install the Unit properly as specified in the operation manual. Improper
installation of the Unit may result in malfunction.
• When transporting the Units, use special packing boxes. Be careful not to
apply excessive vibration or shock during transportation and not to drop
the product.
• Store the Units within the following temperature and humidity ranges:
Storage temperature: –20 to 75
°C, storage humidity: 10% to 90% (with no
icing or condensation)
• When using a thermocouple-input Temperature Sensor Unit, do not touch
the cold junction compensator. Doing so may result in incorrect temperature measurement.

EC Directives 6

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
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
(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 CPM2C PCs comply with EC Directives. To ensure that the machine or
device in which the CPM2C PC is used complies with EC Directives, the PC
must be installed as follows:
1,2,3... 1. The CPM2C 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. Basic insulation is provided between the commons of different polarities of
the output relay for the CPM2C-20@@R (model with 20 relay output
points).
When connecting devices that operate at voltages higher than 50 VAC and
those that operate on DC power supplies to adjoining relay output terminals, use different DC power supplies for output devices from those for input devices and the CPM2C power supply.
4. CPM2C 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.

EC Directives 6
6-4 Relay Output Noise Reduction Methods
The CPM2C PCs conform to the Common Emission Standards (EN61000-6-
4) of the EMC Directives. However, the noise generated when the PC is
switched ON or OFF using the relay output may not satisfy these standards. 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 EN61000-6-4 for more details.)
Countermeasures are not required if the frequency of load switching for the
whole system with the PC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system with the PC included is 5 times or more per minute.
Countermeasure Examples
When switching an inductive load, connect a surge protector, diodes, etc., in
parallel with the load or contact as shown below.
Circuit Current Characteristic Required element
AC DC
Yes Yes If the load is a relay or solenoid, there
is a time lag between the moment the
circuit is opened and the moment the
load is reset.
If the supply voltage is 24 to 48 V,
insert the surge protector in parallel
with the load. If the supply voltage is
100 to 200 V, insert the surge protector
between the contacts.
The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from experiments, and take into consideration that
the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the
current that flows into the load when
the circuit is closed again.
The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.
CR method
Powe r
supply
Inductive
load
xxiii
EC Directives 6
No Yes The diode connected in parallel with
the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current
will be converted into Joule heat by the
resistance of the inductive load.
This time lag, between the moment the
circuit is opened and the moment the
load is reset, caused by this method is
longer than that caused by the CR
method.
The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.
The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.
Yes Yes The varistor method prevents the impo-
sition of high voltage between the contacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the circuit is opened and the moment the load
is reset.
If the supply voltage is 24 to 48 V,
insert the varistor in parallel with the
load. If the supply voltage is 100 to
200 V, insert the varistor between the
contacts.

CPM2C Features and Functions Section 1-1
1-1 CPM2C Features and Functions
1-1-1 CPM2C Features
The CPM2C PCs incorporate a variety of features in a compact Unit, including
synchronized pulse control, interrupt inputs, pulse outputs, and a clock function. The CPM2C CPU Unit is a stand-alone Unit that can handle a broad
range of machine control applications and it is small enough to be incorporated as the control unit in almost any free-standing machine.
The full complement of communications functions provide communications
with personal computers, other OMRON PCs, and OMRON Programmable
Terminals. These communications capabilities allow the user to design a lowcost distributed production system.
Basic Functions
CPU Unit Variations The CPM2C PCs are one-piece PCs with 10, 20, or 32 I/O points in I/O termi-
nals or a built-in connector. There are 3 types of outputs available (relay outputs, sinking transistor outputs, and sourcing transistor outputs). All CPM2C
PCs require a 24-VDC power supply.
Expansion I/O Units Up to 5 Expansion I/O Units can be connected to the CPU Unit to increase the
PC’s I/O capacity to a maximum of 192 I/O points. There are 23 different
Expansion I/O Units available, including Units with 10 I/O points, 24 I/O points,
32 I/O points, 8 input points, 8 output points, 16 inputs points, and 16 output
points. The maximum I/O capacity of 192 I/O points is achieved by connecting
five 32-point Expansion I/O Units to a CPU Unit with 32 built-in I/O points.
Share Programming
Devices
Programming and monitoring for the CPM2C can be performed with CX-Programmer version 2.1 or higher or with a Programming Console. Programming
is also possible with the SYSMAC-CPT or SYSMAC Support Software.
The communications port can be used simultaneously as two ports: Peripheral and RS-232C.
The peripheral port supports Programming Devices,
Host Link, and no-protocol communications.
The RS-232C port supports Host Link, no-protocol
(
serial),1:1 Link,and 1:1 NT Link communications.
CPU Units with 10 I/O points (relay or transistor
outputs) or with 20 or 32 I/O points (transistor
outputs only) are available. Expansion I/O Units
can be connected to increase capacity to 192 I/O
points.

CPM2C Features and Functions Section 1-1
Built-in Motor Control Capability
Synchronized Pulse
Control
(Transistor Outputs Only)
Synchronized pulse control provides an easy way to synchronize the operation of a peripheral piece of equipment with the main equipment. The output
pulse frequency can be controlled as some multiple of the input pulse frequency, allowing the speed of a peripheral piece of equipment (such as a supply conveyor) to be synchronized with the speed of the main piece of
equipment.
High-speed Counters and
Interrupts
The CPM2C has a two kinds of high-speed counter inputs. The high-speed
counter input has a response frequency of 5 or 20 kHz and the interrupt inputs
(in counter mode) have a response frequency of 2 kHz.
The single high-speed counter can be used in any one of the four input
modes: differential phase mode (5 kHz), pulse plus direction input mode
(20 kHz), up/down pulse mode (20 kHz), or increment mode (20 kHz). Interrupts can be triggered when the count matches a set value or falls within a
specified range.
The interrupt inputs (counter mode) can be used for incrementing counters or
decrementing counters (2 kHz) and trigger an interrupt (executing the interrupt program) when the count matches the target value. Four interrupt inputs
can be used in the 20- and 32-point CPU Units and two interrupt inputs can be
used in the 10-point CPU Units.
Easy Position Control with
Pulse Outputs
(Transistor Outputs Only)
CPM2C PCs with transistor outputs have two outputs that can produce 10 Hz
to 10 kHz pulses (single-phase outputs).
When used as single-phase pulse outputs, there can be two outputs with a
frequency range of 10 Hz to 10 kHz with a fixed duty ratio or 0.1 to 999.9 Hz
with a variable duty ratio (0 to 100% duty ratio).
When used as pulse plus direction or up/down pulse outputs, there can be
just one output with a frequency range of 10 Hz to 10 kHz.
High-speed Input Capabilities for Machine Control
High-speed Interrupt Input
Function
The 20-point and 32-point CPU Units have 4 inputs that can be used as interrupt inputs and the 10-point CPU Units have 2 inputs that can be used as
interrupt inputs. These inputs are shared with quick-response inputs and interrupt inputs in counter mode and have a minimum input signal width of 50
µs
and response time of 0.3 ms. When an interrupt input goes ON, the main program is stopped and the interrupt program is executed.
Quick-response Input
Function
Regardless of the cycle time, the 20-point and 32-point CPU Units have 4
inputs that can be used as quick-response inputs and the 10-point CPU Units
have 2 inputs that can be used as quick-response inputs. These inputs are
shared with interrupt inputs and interrupt inputs in counter mode; they can
reliably read input signals with a signal width as short as 50
µs.
Stabilizing Input Filter
Function
The input time constant for all inputs can be set to 1 ms, 2 ms, 3 ms, 5 ms,
10 ms, 20 ms, 40 ms, or 80 ms. The effects of chattering and external noise
can be reduced by increasing the input time constant.

CPM2C Features and Functions Section 1-1
Other Functions
Interval Timer Interrupts The interval timer can be set between 0.5 and 319,968 ms and can be set to
generate just one interrupt (one-shot mode) or periodic interrupts (scheduled
interrupt mode).
Calendar/Clock In CPU Units with a built-in clock, the clock (accuracy within 1 minute/month)
can be read from the program to show the current year, month, day, day of the
week, and time. The clock can be set from a Programming Device (such as a
Programming Console) or the time can be adjusted by rounding up or down to
the nearest minute.
Long-term Timer TIML(
−−) is a long-term timer that accommodates set values up to 99,990
seconds (27 hours, 46 minutes, 30 seconds). When combined with the SECONDS TO HOURS conversion instruction (HMS(
−−)), the long-term timer pro-
vides an easy way to control equipment scheduling.
Greater Data Handling Capability with Expansion Units
Analog I/O Supported Up to 4 Analog I/O Units can be mounted to the CPM2C. For each Analog I/O
Unit mounted to the Unit, 2 analog input points and 1 analog output point are
available. By mounting 3 (see note) Analog I/O Units, a maximum of 8 analog
input points and 4 analog output points can be made available. (By using a
combination of the PID(
−−) instruction and PWM(−−) instruction, time propor-
tional control is possible.)
• The ranges supported for analog input signals are 0 to 5 V, 0 to 10 V, –10
to 10 V, 0 to 20 mA, and 4 to 20 mA, and the resolution is 1/6000 (full
scale). The average processing function and power interruption detection
function can be used.
• The ranges supported for analog output signals are 1 to 5 V, 0 to 10 V,
–10 to 10 V, 0 to 20 mA, and 4 to 20 mA, and the resolution is 1/6000 (full
scale).
Note When using the CPM2C-PA201, there is a limit to the number of CPM2C-
MAD11 Units that can be connected. This limit ensures that the power consumption of the CPU Unit, Expansion Units, and Expansion I/O Units does not
exceed the total power capacity of the service power supply from the Power
Supply Unit (24 V x 600 mA = 14.4 W).
• CPU Unit with 4-W power consumption: Connect no more than two
CPM2C-MAD11 Units
• CPU Unit with 3-W power consumption: Connect no more than three
CPM2C-MAD11 Units
Temperature Sensor Units Up to 4 Temperature Sensor Units can be mounted to the CPM2C. There are
2 models of Temperature Sensor Unit: One for input from a thermocouple sensor and one for input from a platinum resistance thermometer sensor. There
are 2 input points on each Temperature Sensor Unit.
• Thermocouple inputs (and measurement ranges): K (–200 to 1,300
°C,
0.0 to 500.0
°C), J (–100 to 850°C, 0.0 to 400.0°C).
• Platinum resistance thermometer inputs (and measurement ranges):
Pt100 (–200.0 to 650.0
°C), JPt100 (–200.0 to 650.0°C).
CompoBus/S I/O Link
Units
The CPM2C can be used as a CompoBus/S Slave (with 8 built-in inputs and 8
built-in outputs) by connecting a CompoBus/S I/O Link Unit. Up to
5 CompoBus/S I/O Link Units can be connected to the CPM2C. In addition to
the conventional “PC + Remote I/O” type of distributed I/O control, “PC + miniature PC” distributed CPU control is now possible. This means increased
5
CPM2C Features and Functions Section 1-1
modularization, allowing greater standardization of design, improved suitability to special needs, and easier replacement of malfunctioning Units.
Simple Communications
Unit
A Simple Communications Unit can be added to achieve data transfers with
general-purpose communications components without preparing communications programs in the PC. Up to 32 communications components can be connected, including a combination of communications components supporting
the CompoWay/F protocol along with temperature controllers and Digital
Panel Meters supporting the SYSWAY protocol.
Complete Communications Capabilities
Host Link A Host Link connection can be made through the PC’s communications port
used as a RS-232C or peripheral port. A personal computer or Programmable
Terminal connected in Host Link mode can be used for operations such as
reading/writing data in the PC’s I/O memory or reading/changing the PC’s
operating mode.
No-protocol
Communications
The TXD(48) and RXD(47) instructions can be used in no-protocol mode to
exchange data with standard serial devices. For example, data can be
received from a bar code reader or transmitted to a serial printer. The serial
devices can be connected to the communications port as a RS-232C or
peripheral port.
High-speed 1:1 NT Link
Communications
In a 1:1 NT Link, an OMRON Programmable Terminal (PT) can be connected
directly to the CPM2C. The PT must be connected to the communications
port as an RS-232C port (not as a peripheral port).

CPM2A, SRM1(-V2), or a C200HS or C200HX/HG/HE PC. The 1:1 PC Link
allows automatic data link connections. The PC must be connected to the
communications port as an RS-232C port (not as a peripheral port).
