The PLC control system, or Programmable Logic Controller, is a digital operation electronic device designed specifically for industrial production. It uses a type of programmable memory to internally store programs, execute logical operations, sequential control, timing, counting, and arithmetic operations based on user instructions, and controls various types of machinery or production processes through digital or analog input/output. It is a core component of industrial control.Since the introduction of the Programmable Logic Controller (PLC) in the United States in the 1960s, which replaced traditional relay control devices, PLCs have rapidly developed and been widely used around the world. At the same time, the functionality of PLCs has continuously improved. With the ongoing development of computer technology, signal processing technology, control technology, and network technology, as well as the increasing demands of users, PLCs have added functions such as analog processing and motion control on top of basic discrete control. Today’s PLCs are no longer limited to logical control; they also play a very important role in motion control and process control. Let’s take a look at these animated diagrams!PLC Sequential Control
