This document introduces the features and uses of the CQM1 series CPUs, including designing systems, creating sequence diagrams, installing and wiring, allocating I/O bits, drawing ladder diagrams, coding ladder diagrams, turning on PCs, inputting programs, debugging, testing runs, saving programs, and running systems.
This manual introduces the SYSMAC CQM1 PLC series, describing the overall system configuration, the six‑unit architecture (CPU, power supply, and I/O units), and the steps needed to design, install, and operate a CQM1 system.
It covers hardware installation, wiring, DIP‑switch settings, communication options (RS‑232C, host link, peripheral port), interrupt functions, and detailed technical specifications for each CPU model, including programming and troubleshooting guidance.
