The basic structure of PLC and DCS is the same. PLC has developed to this day and has been fully transplanted to the computer system control, and the traditional programmer has long been eliminated. PLCs for small applications generally use touch screens, and PLCs for large-scale applications use computer systems in an all-round way. Like DCS, the controller and IO station use field bus (generally based on the RS485 or RS232 asynchronous serial communication protocol), if there is no expansion requirement between the controller and the computer, that is to say, only one computer is used. In this case, this bus communication is also used. But if more than one computer is used, the system structure will be the same as DCS, and the upper computer platform uses the Ethernet structure. This is one of the reasons why the PLC has become larger and the concept of DCS is blurred.
