Learn DCS system ---a large system

(1) The DCS system is a large system. Its controller has powerful functions and plays an important role in the system.

The data highway is the key to the system. Therefore, the overall investment must be made in one step, and sub-

sequent expansion is difficult. However, the functions of FCS are completely decentralized, information processing is

on-site, and digital intelligent field devices are widely used, which makes the functions and importance of the controller

relatively weak. Therefore, the investment starting point of the FCS system is low, and it can be used, expanded, and

put into operation at the same time.

 

(2) The DCS system is a closed system, and the products of various companies are basically incompatible. The FCS system

is an open system, and users can choose various devices from different manufacturers and brands to connect to the field-

bus to achieve the best system integration.
