What Is the L02CPU-CM?
The L02CPU-CM is a CPU module from Mitsubishi Electric's MELSEC iQ-L series of programmable controllers. The "CM" suffix identifies it as part of the iQ-L modular rack family, and the module is designed as the central processing unit of a compact, expandable PLC system. It is a current, actively referenced product in industrial automation catalogues and is widely used as a control brain for machines, production cells and utility systems.
In practical terms, the L02CPU-CM is not a general-purpose computer. It runs a deterministic scan-based program, executes ladder/structured logic, and exchanges I/O with digital and analogue modules across a backplane or base unit. Typical published attributes include a program capacity of 20K steps, a built-in
