Misunderstanding and Correction Method of PLC Decryption
Programmable controller is a new type of industrial control device developed by microprocessor as the core, integrated computer technology, automatic control technology and communication technology. It combines the advantages of both traditional relay control technology and modern computer information processing, and becomes the first of the three pillars of industrial automation (PLC, ROBOT, CAD/CAM). The software of PLC is easy to learn, the hardware operation of PLC is stable and reliable (average time between failures is 20,000 to 50,000 hours), and the engineering design and construction period of PLC is short (even several hours).
