Design And Implementation Of DCS System For Hebei Silicon Valley Chemical

DCS is Distributed Control System. Along with the industrial product line increases ceaselessly. The Distributed Control System (DCS) has been applied more and more widely and has become the mainstream in the controlling field. As a developing system, applications of many New technologies promote the development of DCS.A long with the rapid applications of Field bus technology and Industrial Ethemet, there is a new model of structure for DCS. That is, it combines with Field bus technology and Industrial Ethemet, and becomes a new type which is more competitive.The DCS of Hebei adopts redunctance design.It is composed of server,industry control computer and PLC. The system is configurated with configuration software on the basis of different flows,the computers of system commucate by LAN. The system carries out data gather and control with distributed locale control station,data gather station and so on,and transmits the data to production monitor grade computer which centralize the administration of data coming from process control grade,such as optimizing calculation, statistic report forms and trouble diagnosis, alarm display.The Distributed Control System has been desiened and debugged. The system has good currency high re liability and high performance/price ratio and it has good market reliability and high foreground.
