PLC在沉砂沉淀池行车控制系统中的应用

Application of PLC SLC500 in the Control System of the Traveling Crane for the Sand Precipitating Pool

本文简要介绍了罗克韦尔SLC500系列可编程控制器的主要特点，以我厂沉砂沉淀池控制系统中的应用为例，详细论述了采用SLC500可编程控制器，并通过DH-485网络构建的行车控制系统，以及DH-485网络与DH＋网络实现通讯的方法。

This paper introduces briefly the main characteristics of the programmable controller SLC50. Taking the control system of the traveling crane for the sand precipitating pool in our factory as an example, we discuss in detail the control system of the traveling crane, which is constructed by SLCS00 programmable controller and networks DH-485. The implementation of the commu- nication between the networks DH-485 and DH＋ is also studied.
