It uses programmable memory to internally store programs, execute logical operations, sequential control, timing, counting and arithmetic operations and other user-oriented instructions, and control various types of machinery or production processes through digital or analog input / output. The working principle of PLC controller is mainly based on the interaction between input, output and central processing unit (CPU). External devices input signals into PLC, and after processing, PLC outputs the corresponding signals to other devices. Specifically, the working process of PLC controller includes the following steps: Input stage: PLC control The controller receives signals from external devices through the input interface. These signals can be from various input devices such as sensors, buttons, switches, encoders, etc. Calculation stage: The received input signal will be passed to the central processing unit (CPU). The CPU is the core component of the PLC and contains one or more processors for executing programs written by the user. In the calculation stage, the CPU will process the input signal through algorithms, logical operations, and conditional statements. Output stage: After the CPU processes the input signal, it sends the control command to the output module.
