The working principle of the PLC (programmable logic controller) control system is as follows:

Input signal collection: PLC collects status signals of external sensors or switches through input modules, such as button switches, sensors, switch signals, etc. These input signals are converted into digital signals for internal processing by the PLC.

Program execution: There is a memory inside the PLC that stores programs, usually called the memory area. In the memory, the user can write a control program, usually using a programming language similar to Ladder Diagram or Structured Text. The PLC executes different instructions according to the sequence of the program to control the output device.

Logic processing: PLC performs logic processing according to the written control program. It will judge, calculate and make decisions based on the status of the input signal, and then determine the control operations that need to be performed.

Output control: According to the results of logical processing, PLC controls external actuators or execution devices, such as motors, valves, lights, etc., through the output module. The output module converts the digital signals inside the PLC into analog signals or switching signals that can control external devices.

Monitoring and communication: PLC usually has a monitoring function, which can monitor input and output status, and provide alarm, fault detection and other functions. In addition, PLC can also exchange data with other devices through communication interfaces, such as communicating with host computers or other PLCs, to achieve more complex control functions.
