A brief introduction to the PLC controller system

The PLC control system is a new generation of industrial control equipment that introduces microelectronics technology, computer technology, automatic control technology, and communication technology on the basis of traditional sequential controllers. Its purpose is to replace relay, execution logic, timing, counting and other sequential control functions, and establish a flexible remote control system. It has the characteristics of strong universality, convenient use, wide adaptability, high reliability, strong anti-interference ability, and simple programming.
