摘要
介绍了一种基于WinCC和S7-300 PLC实现PID控制的方法,利用FB41功能模块实现PID控制,通过WinCC进行实时监控,具有图形显示直观,参数设置方便等优点。
A STEP7 and WinCC based method of controlling PID is introduced.The PID control is realized by the FB41 function of S7-300 PLC.In this way,the real-time monitoring system can run based on WinCC.This method has advantages of direct-viewing display of graphical and easy setup of parameters,etc.
