Distributed control system is the product of the combination of computer technology, communication technology, display technology and control technology, and has been widely used in different industries. Electric actuator is a common electrical equipment in industrial process control systems.
It is a multi-level computer system composed of a process control level and a process monitoring level with a communication network as the link. It integrates 4C technologies such as computer, communication, display (CRT) and control (Control). The idea is decentralized control, centralized operation, hierarchical management, flexible configuration, and convenient configuration.
The realization process of a remote control is: the field sensor inputs the field process parameters to the CPU through the I/O module and the communication interface, the CPU processes according to the designed program, and outputs the result to the scene through the communication interface and the I/O module. controller, thus realizing a simple remote control.
