PLC在超低速升降控制系统中的应用研究

A RESEARCH ON THE APPLICATION OF PLC TO THE ULTRA-LOW SPEED ELEVATION CONTROL SYSTEM

本文介绍了基于PLC控制的超低速升降系统,该系统采用组态软件实现与PLC、变频器等控制器的远程通讯,以实现对工业现场的实时控制.

In this paper,an ultra-low speed elevation system,with PLC used for controlling,is introduced.Making use of configuration software,this system has realized the remote communication with PLC,variable frequency-conversion controller and others and,thus,made the worksite real-time control available.
