A PLC CPU module is the "brain" of an industrial control system, responsible for reading inputs (sensors, switches), executing user programs (logic, math, timing), making decisions, and sending outputs (motors, lights, valves) to automate processes in manufacturing, energy, water treatment, and more, handling diagnostics, communication, and memory management. It replaces hardwired relays, timers, and counters with flexible software, enabling complex control, data processing, and system monitoring.
