本文介绍了由横河的YS-80系列可编程仪表与立石OMRON的SYSMAC系列C500可编程控制器相配套做为控制核心,组成间歇法生产聚丙烯的自控系统。本系统功能强、优点多,自投入生产以来,平均使每釜生产时间缩短了近15分钟,一级品率一直保持在98％以上。 This article describes the YS-80 series of Yokogawa programmable instrumentation and stand OMRON SYSMAC Series C500 programmable controller matched as the control center, composed of intermittent production of polypropylene control system. The system is powerful and has many advantages. Since it was put into production, the average production time of each pot has been shortened by nearly 15 minutes. The first class product rate has been maintained at over 98%.
