PLC already has the control function of analog quantity, and some PLC systems have even quite powerful analog quantity processing capability, such as Siemens S7-400, ABB control board Control Logix and Schneider Quantum system. And DCS also has quite strong logic processing capabilities.
The basic structure of PLC and DCS is the same. PLC has developed to today and has been fully transplanted to computer system control. Traditional programmers have long been Be 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
Just like DCS, the host computer platform uses the Ethernet structure. This is one of the reasons why the concept of DCS is blurred after the large-scale PLC.
3. The development direction of PLC and DCS:
Miniaturized PLC will develop towards a more professional use perspective, such as more targeted functions, more targeted application environment, and so on. Large
The boundary between PLC and DCS gradually fades until it is completely integrated.
