基于S7-400PLC的三盘磨浆机控制系统的应用与实现

摘要

The twinflo_43 refiner operation in a paper production line taken as the main control object.The DCS was built based on S7-400PLC,Profibus-DP and internet.The goal of completely auto-controlling was achieved.The application results indicated that this system achieved shorter feeding time,faster tuning speed,smaller overshoot,and the disc blade could be protected effectively.%以制浆生产线为背景,以三盘磨浆机为主要控制对象,基于S7-400PLC、Profibus-DP总线、工业以太网通信技术构建DCS,实现对磨浆机的全自动控制.实际运行效果表明,该方案不仅进刀时间短、调节速度快、超调量小,而且可以有效地保护盘磨机的磨盘.
