The CQM1 is a compact, high-speed PC made up of a CPU Unit, Power Supply Unit, and I/O Units that together provide up to 256 total I/O points. These components lock together at the sides, allowing simple changes in the size and capacity of the PC. There are six types of CPU Unit, shown in the table below. All of the CPU Units except for the CQM1-CPU11-E have a built-in RS-232C interface.
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
