摘要
二聚造粒的控制系统将由日本三菱FX系列PLC改造升级为PCS7系统,而三聚造粒已于2013年升级为PCS7系统,根据监控需要,要将两系统并网,实现在同一台操作站可以监控二三聚造粒的目的。文章主要介绍了二聚造粒控制系统升级情况以及升级遇到的难点,最终实现与三聚并网。
The control system of dimer granulation will be upgraded from Japan’s Mitsubishi FX series PLC to PCS7 system,and trimer granulation has been upgraded to PCS7 system in 2013.For the monitoring needs,the two systems must be connected to the network to achieve simultaneous control of dimer and trimer granulation in the same operation station.This article mainly introduces the upgrade of the control system of dimer granulation and the difficulties encountered in the process,and finally realizes integration with the trimer granulation.
