This article will tell you in detail! What is PLC PLC (Programmable Logic Controller) can be used as a programmable controller, and its most basic and widespread application field is to replace traditional relay circuits and achieve logic control and sequence control. PLC consists of CPU and input/output modules. It has multiple control functions, data acquisition, storage and processing functions, mathematical operation functions, and input/output interface conditioning functions. In addition, there are communication networking functions, human-machine interface functions, and editing and debugging functions. Mainly applied in traditional industrial control fields, such as steel, petroleum, chemical, textile, transportation, machinery manufacturing and other industries. What is RTU RTU (Remote Terminal Unit) is a remote measurement
