工程控制计算机（又称工控机）是一种基于计算机技术的新型工控设备。 已成

Engineering control computer (also known as industrial control computer) is a new type of industrial control equipment based on computer technology. It has become the standard equipment for industrial control and is widely used in various fields. Industrial control computers are ideal supporting products for production automation. Industrial programmable logic controller (PLC) plays an important role in industrial control. PLC function, easy operation, strong adaptability, high reliability, strong anti-interference ability, simple programming and so on. . Programmable controllers first appeared in the United States in the late 1960s. At that time it was called a programmable logic controller. Its purpose is to replace the relay to perform sequence control, logic and other functions. The basic idea of ​​the project is to combine the comprehensive functions of the computer, the flexibility and versatility of the relay control system, simplicity, understanding, convenience, and low cost. General controller hardware standard. . . According to the actual application of the object, the control content is stored in the user program of the controller. The connection between the controller and the control object is very convenient. For the user, the programmable controller is a non-contact device. The production process can be changed by modifying the program, so that the programmable controller can be selected at the beginning of the project and during the implementation process. It has been implemented. On the other hand, from the perspective of the manufacturer's programmable controller, in the production stage suitable for mass production, there is no need to adjust the controller to meet the needs of users. These features make the programmable controller quickly recognized by the industrial control community shortly after its introduction.
