摘要
介绍了一种新的蒸发工段DCS控制方法,采用S7PLC CPU 414-2DP,连接ET200系列的分布式I/O系统及标准服务系统所组成的DP控制网络,对碱回收黑液蒸发过程实施集散控制的优化控制方案。
The article introduces a new distributed Control System(DCS) for black liquor evaporating process. use a SRPLC CPU414-2DP module is corporated to the DP control net. composed of a distributed I/O System and an ET200Series Standard Service System are adopted.
