What is PLC Architecture and Module Overview about?
The document describes the basic architecture of a programmable logic controller (PLC). It explains that a PLC has a central processing unit (CPU), memory, input and output modules, and a power supply. Inputs come from field devices like sensors and switches, while outputs control devices like motors and lights. The input and output modules electrically isolate signals and transfer them to and from the CPU. Common types of input modules include discrete and analog modules for DC, AC, and electronic signals.
