The CQM1H’s rack-less modular design lets you customize your control

system by adding “inner boards” for advanced functions, as well as

specialized I/O and communications modules.

CQM1H offers the most flexibility of all PLC systems in its class.

• 4 different base CPUs to choose from; 16 DC inputs built in;

expands up to 512 points

• No separate backplane required

• Inner Boards allow “customized” configuration of the CPU

• Serial communications inner board supports protocol macro feature

for communication with third-party serial devices

• Supports all existing and new CQM1 I/O and specialized I/O modules

• Optional memory cassettes allow backup of sensitive data, provides

a real-time clock

• ControllerLink network transmits 8 kword data packets at up to 2 Mbps;

32 nodes

• Advanced instruction set includes PID, floating point math, protocol

macro instructions and more

• CompoBus/S, SYSMAC BUS and AS-interface masters support remote I/O

• Up to 15.2 kwords of program memory

Basic Configuration

Select the CPU and I/O modules (discrete, analog and dedicated special

function types) then determine the power supply based on the current

consumption. The I/O Control and Interface adapters give you the option

of dividing the CPU and I/O system into two narrower units than the

examples shown below. The CQM1H-CPU51/CPU61 models offer space-saving

position and motion control solutions as well as additional analog and serial

communications capabilities right at the CPU.
