Micro Programmable Controller
CPM2A
The CPM2A brick-style controllers offer one of
the most powerful, small-scale control solutions
in the industry today. They provide 20, 30, 40
or 60 I/O point CPUs, pulse I/O for position
control, multiple communications ports and a
powerful instruction set.
DExpandable up to 120 I/O points
DPeripheral and RS-232C ports standard for direct
connection to serial devices and programming tools
DRemovable terminals
DSynchronized pulse control coordinates input devices
with control devices
DAuxiliary 24 VDC supply (AC type only)
DRelay or Transistor outputs
DAnalog I/O expansion modules available
DTemperature sensor input expansion modules available
DReal-time clock
D20 kHz high-speed counter input
DTwo, 10 kHz pulse outputs for position control
applications
Basic Configuration
Up to three Expansion I/O Modules or Special I/O Modules can be connected to any CPM2A CPU. The mounting order does not affect
the number of modules that can be mounted.

JCONFIGURATION
The CPM2A PLCs incorporate a variety of features, including
synchronized pulse control, interrupt inputs, pulse outputs,
analog settings, and a clock function. Use the CPM2A CPU as a
stand-alone controller for a broad range of machine control
applications.
The CPM2A easily communicates with personal computers, other
OMRON PLCs, and OMRON Programmable Terminals. These
communications capabilities allow the user to design a low-cost
distributed production system.
The CPU contains 20, 30, 40, or 60 I/O points and Expansion I/O
blocks can be added to provide a total I/O capacity of up to 120 I/O
points. Analog I/O modules, Temperature Sensor modules, and
CompoBus/S I/O Link modules can also be connected.
Peripheral Port
Use this port for programming devices (compa-
tible with other OMRON PLCs) as well as Host
Link and no-protocol communications.
RS-232C Port
This port can be used for a Host
Link, no-protocol, 1:1 data link, or
1:1 NT Link communications.
JTIME-PROPORTIONAL CONTROL
The CPM2A performs simple-to-program, time-proportional
control using up to three Analog I/O modules (maximum 6 analog
inputs and 3 analog outputs) and the PID and PWM expansion
instructions. These instructions set the parameters for PID
control and a pulse output with variable duty ratio. For increased
reliability, an open-circuit detection function can be used with the
1 to 5 VDC and 4 to 20 mA analog input settings.
For temperature monitoring applications, CPM2A accepts up to 6
inputs (two per module) from Temperature Sensor Input modules.
The PID instruction can manipulate the input from either
thermocouple or platinum resistance thermometer sensors.
JDISTRIBUTED I/O CONTROL
Omron’s CompoBus/S Network provides distributed CPU control
based on a “PLC + compact PLC” configuration which provides
improvements over distributed control based on “PLC + remote
I/O” configurations. The distributed CPU control makes
equipment module, so designs can be standardized, special
needs can be addressed and modules can be replaced easily in
the event of breakdown without affecting the main CPU.

JBUILT-IN MOTOR CONTROL CAPABILITY
Synchronized Pulse Control (transistor output models only)
Synchronized output pulse control provides an easy way to
coordinate the operation of a peripheral piece of equipment with
the main equipment. The output pulse frequency can be
controlled as a 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.
Encoder CPM2A Motor
Pulses are output as a fixed multiple of the input frequency.
3G3MV Drive
A--65
Micro Programmable Controller CPM2A
JHIGH-SPEED COUNTERS AND INTERRUPTS
The CPM2A has a total of five high-speed counter inputs. The
one high-speed counter input has a response frequency of
20 kHz/5 kHz, and the four interrupt inputs (in counter mode)
have a response frequency of 2 kHz.
Four Input Modes
The 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.
Interrupt Inputs
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. Use this for target-value comparison or
range comparison control that is unaffected by the cycle time.
Easy Position Control with Pulse Outputs
(transistor output models only)
The CPM2A PLCs 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.

The CPM2A has two pulse outputs. You can configure these outputs as two single-phase outputs without acceleration and deceleration,

JHIGH-SPEED INPUT CAPABILITIES FOR
MACHINE CONTROL
High-speed Interrupt Input Function
There are four inputs used for interrupt inputs (shared with quick-
response inputs and interrupt inputs in counter mode) with a
minimum input signal width of 50 µs and a 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
There are four inputs used for quick-response inputs (shared with
interrupt inputs and interrupt inputs in counter mode) that can
reliably read input signals with a signal width as short as 50 µs.
Quick-response inputs are received into an internal buffer, so
signals that change status within a cycle can be processed.
Stabilizing Input Filter Function
The input time constant for all inputs can be set to 1 ms, 2 ms,
3ms,5ms,10ms,20ms,40ms,or80ms.Theeffectsof
chattering and external noise can be reduced by increasing the
input time constant.
Interval Timer Interrupts
The interval timer offers a 0.5 and 319,968 ms range and can be
set to generate just one interrupt (one-shot mode) or periodic
interrupts (scheduled interrupt mode) to match the application.
JOTHER FUNCTIONS
Analog Settings
There are two controls on the CPU that can be turned to change
the analog settings (0 to 200 BCD) of timers and counters. These
controls can be used to easily change or fine-tune machine
settings such as a conveyor belt’s pause time or feed rate.
Calendar/Clock
The built-in 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
The long-term timer provides an easy way to control equipment
scheduling. Use two instructions to set this up. The long-term
timer instruction (TIML) lets you set values up to 99,990 seconds
(27 hours, 46 minutes, 30 seconds) and the Seconds-to-Hours
conversion instruction (HMS) lets you schedule this with other
clock functions.
