1. High reliability Because DCS disperses the system control function on each computer, and the system structure adopts a fault-tolerant design, the failure of one computer will not lead to the loss of other functions of the system. In addition, due to the fact that the tasks undertaken by the various computers in the system are comparatively ...

There are many new developments in the field of DCS-related, which are mainly manifested in the following aspects. (1) The system function is developing in the direction of openness. The structure of traditional DCS is closed, and it is difficult to be compatible with DCSs from different manufacturers. The open DCS will allow users to set a larger system ...

Examining the hierarchical structure of DCS, DCS level and control management level are the two most basic links that make up DCS. The process control stage specifically realizes the decentralized control functions such as signal input, conversion, operation and output. The controls at the process control level vary in different DCS, ...

To put it simply, DCS is mainly used for process automation, PLC is mainly used for factory automation (production lines), and SCADA is mainly for wide-area needs, such as oil fields and pipelines that stretch for thousands of miles. If from the point of view of computers and networks, they are unified, and the reason for the difference is mainly in ...
