Programmable controller (PC for short). Different from the personal computer PC, it is represented by PLC. The International Electrotechnical Commission (IEC) has issued regulations on PLC: A programmable controller is an electronic system for digital operation, designed for use in industrial environments. It uses programmable memory to store instructions for performing logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital and analog inputs and outputs. Programmable controllers and related equipment should be designed according to the principle of being easy to form an integral part with industrial control systems and easy to expand their functions. Characteristics of PLC: strong versatility, easy to use, wide adaptability, high reliability, strong anti-interference ability, simple programming, etc. Structure of PLC Composition of PLC: For box-type PLC, there is a CPU board, I/O board, display panel, memory block, power supply, etc. Of course, it is divided into several models according to CPU performance, and there are several specifications according to the number of I/O points. For modular PLC, there are CPU module, I/O module, memory, power module, base plate or rack. The basic structure diagram of PLC is as follows:
