Omron CQM1H-CPU21 (CQM1HCPU21) PLC programmable controller CPU Unit
The original modular PLC system for versatile machine control
Distributed control with the high-speed,
high-capacity Controller Link network
Use Controller Link to automatically exchange data between PLCs, and
to maintain programs and data of all connected PLC’s from a single PC.
You can share operating data among machines without any programming, and centralize the supervision of machine productivity, production progress and quality data.
Advanced inner boards enable flexible system
configuration
Omron CQM1H-CPU21
Advanced Inner Boards can be added to the CPU Unit to respond flexibly to the applications of each machine. Use of the Serial Communications Board, for example, enables connection with peripheral
components, like temperature controllers and bar-code readers, that
are equipped with serial ports. This kind of flexibility lets you build
systems that better match the specifications and scale of the machine
or equipment being controlled.
I/O points and memory capacity doubled to provide
an extra margin of control
The I/O capacity, program capacity, and Data memory have been
doubled over those of previous CQM1 models. This gives you an extra
margin of control to meet the data processing load that accompanies
the growing complexity and advanced functions of today’s control
systems, and assures you of plenty of capacity for the I/O points of
dedicated I/O Units for your applications.
Omron CQM1H-CPU21
Establish distributed control with the Controller Link Network to transfer data easily between PLCs in the
network.
Advanced Inner Boards allow flexible system
configurations.
A variety of advanced Inner Boards, such as the High-speed Counter
Board and Serial Communications Board, are available. Mount the
desired Inner Board in the CPU Unit to meet the requirements of each
machine application. A Serial Communications Board can communicate with essentially any device with a serial port, such as temperature
controllers or bar-code readers. The optimum system can be configured to match the specifications and scale of the machine or equipment
being controlled.
Increased capacity and speed provide extra capacity
for control applications.

The program capacity, I/O capacity, and DM capacity have been doubled compared to the original CQM1 series. A 16 Kword Memory Cassette can be installed to accommodate the storage and transfer of the
program. Furthermore, the execution times have been reduced from
0.50 ms to 0.375 ms for basic instructions and from 23.5 ms to 17.7 ms
for special instructions (MOV). Overall, the cycle time has been reduced by about 25%.
Flexible System Configuration
The CQM1H does not require a Backplane and is constructed by connecting Units via a parallel bus connector at the side of each Unit, allowing flexible system configuration and the most efficient use of space.
The CPU Unit contains 16 built-in DC input points. Two Inner Boards
can be mounted in the CPU Unit. One Controller Link Unit (a Communications Unit) and a combined maximum of eleven I/O Units can also
be connected.
