As a general industrial control computer, in the past 30 years, programmable controllers have developed from scratch, realizing the leap from wiring logic to storage logic in the field of industrial control; Its function is from weak to strong, realizing the progress from logic control to digital control; Its application field has grown from small to large, realizing the leap from simple control of single equipment to competent for various tasks such as motion control, process control, and distributed control. Today’s programmable controller is becoming the mainstream control equipment in the field of industrial control, playing an increasingly important role in the world.

Definition of programmable controller

Programmable logic controller (PLC) is a new industrial control device based on computer technology. In the draft PLC standard issued by the International Electrical Commission in 1987, PLC is defined as follows:

“PLC is an electronic device specially designed for digital operation in industrial environment. It uses programmable memory to store instructions for logic operation, sequential operation, timing, counting and arithmetic operation, and can control various types of machinery or production processes through digital or analog input and output. PLC and its related peripheral equipment should be easy to connect with The industrial control system is designed according to the principle of forming a whole and easy to expand its functions.
