PLC already has the control function of analog quantity. Some PLC systems have even strong analog quantity processing capability, such as Siemens S7 400, AB’s Control Logix and Schneider’s Quantum system. DCS also has quite strong logic processing capability. For example, we have realized all possible process interlocks and equipment linkage start-stop on AC800F.
In terms of system structure.
The basic structure of PLC and DCS is the same. Today, PLC has been fully transplanted to computer system control, and the traditional programmer has long been eliminated. The small application PLC generally uses touch screen, and the large-scale application PLC fully uses computer system. Like DCS, the controller and the IO station use the 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, if only one computer is used, this bus will also be used for communication. However, if more than one computer is used, the system structure will be the same as DCS, and the upper computer platform uses Ethernet structure. This is one of the reasons why the concept of DCS is fuzzy after the PLC is large-scale.

Miniaturized PLC will develop towards a more professional use perspective, such as more targeted functions, more targeted application environment, and so on. The boundary between large PLC and DCS is gradually weakened until it is fully integrated.
DCS will continue to develop in the direction of FCS. In addition to more decentralized control system, the core of FCS is especially important for instrumentation. The application of FCS abroad has developed to instrument level. The control system only needs to process signal acquisition and provide human-machine interface and logic control. The control of the whole analog quantity is distributed to the field instrument. There is no need for traditional cable connection between the instrument and the control system. The field bus is used to connect the entire instrument system.
