1. Equipment overview

The PLC programming controller is a new type of industrial control device developed based on the foundation of a microblog machine. With the characteristics of small size, strong function, high reliability, and convenient application installation, it quickly occupies a dominant position in my country's industrial control and continuously develops. According to this development situation, the major college branches of the country and various vocational and technical schools of the major national colleges and vocational and technical schools include PLC teaching into teaching tasks as a compulsory course for electronics, electrical and industrial automation. The PLC programming experiment system is a new generation of PLC teaching products developed based on this teaching requirements. Since its launch, it has received unanimous pr--se from teaching teachers and experts in major colleges. The full set of devices are reasonable, powerful, simple and convenient to operate, and have great help for students' understanding and mastering the control principles and methods of programming controllers, and accelerating the programming method of learning PLC. It is an ideal tool for PLC teaching.
