PLC is a new generation of industrial control device that introduces microelectronics, computer technology, automatic control technology, and communication technology on the basis of traditional sequential controllers. Its purpose is to replace relay, execution logic, timing, counting and other sequential control functions, and establish a flexible program control system. The International Electrotechnical Commission (IEC) has issued regulations for PLCs: Programmable controllers are electronic systems designed for digital operations and are specifically designed for use in industrial environments. It uses programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations internally, and controls various types of mechanical or production processes through digital and analog inputs and outputs. Programmable controllers and related equipment should be designed according to the principle of easy integration with industrial control systems and easy expansion of their functions.
PLC has the characteristics of strong universality, convenient use, wide adaptability, high reliability, strong anti-interference ability, and simple programming. It can be expected that in the field of industrial control, the application of PLC control technology will inevitably form a world trend
The PLC program includes both manufacturer’s system programs and user developed application programs. The system program provides a running platform, while also providing necessary public processing for the reliable operation of the PLC program and the conversion of information and information. The user program is designed by the user according to control requirements
PLC is divided into two types: box type and modular type. But their composition is the same. For box type PLCs, there is a CPU board, I/O board, display panel, memory block, power supply, etc. Of course, they are divided into several models based on CPU performance, and there are also several specifications based on I/O points. For modular PLCs, there are CPU modules, I/O modules, memory, power modules, backplanes or racks. PLCs of any type of structure belong to a bus based open architecture, and their I/O capabilities can be expanded and combined according to user needs.
