摘要
介绍西门子PLC在焦炉集气管压力自动控制系统中的应用 ,针对集气管压力对象之间互相干扰的特点 ,采用协调控制思想 ,实现压力系统设定值控制 (SCC)。系统采用西门子S7 30 0、S7 40 0PLC作为现场控制站、研华IPC作为操作员站及调度室站 ,各站通过PROFIBUS总线构成厂级监控网络。人机界面软件为FIXMMI7
In this paper,application of Siemens PLC in control system of coke furnace gas collector pressure is described In the light of actual features of inter disturbed objects,a coordinated control method is used to realize SCC of the pressure system The whole system is composed of Siemens S7 series PLC as field control station and Industrial PC as operator station and control center station All stations communicate each other through PROFIBUS The Machine Man Interface is FIX MMI7 0
