Reliability design of DCS in the Control of Process Industry

Shengyuan Li

Abstract

High reliability is the life of DCS development,is a basic requirement of the process industries continuous operation and the specific production environment.Reliability design of DCS is a rather broad topic.In the case of 250 kt/a ion-exchange membrane caustic soda plant DCS hardware system design,in this paper,we elaborated on the reliability design of DCS in process industry control,which includes the design of DCS network architecture,communication network design,operating station and field control station configuration,system power supply design,etc.
