摘要
介绍了纸机碱回收蒸发工段一种新的DCS控制方法,它是由S7PLC CPU 414-2DP连接ET200系列的分布式I/O系统及标准伺服系统组成DP控制网络,由此对碱回收蒸发工段实施集散控制的优化控制方案。
This paper introduces a new control method. It applies S7 PLC CPU412 -2DP and connects DP controlled network that is formed by distributed input & output (I/O) system belongs to ET200 series and standard auto server system. Using the method, the evaporation workshop about recycling alkali can be intcgratedly and dispersedly controlled.
