According to some problems of shortcomings such as large investment, serious waste of the specific small stirring equipment adopts DCS control system and simple PLC control system not friendly display, design of computer monitoring system based on MCGS for the stirring equipment is put forwar-ded.The control system adopts PLC as the core service, PC as host computer, PLC realizes communica-tion with the host computer through a dedicated communication lines.By using PLC to realize the auto-matic control of stirring equipment controlled objects, using configuration software MCGS to realize the re-al-time operation monitoring of the whole system.The results show that:the system is stable and relia-ble during running, the design required of control objectives and functions are achieved, the actual oper-ating conditions of polypropylene catalyst stirring equipment is fulfilled.
