摘　　要：可编程逻辑控制器(PLC)是种专门为工业环境下应用而设计的数字运算电子系统[1],代替继电器控制系统。学校组建一个功能多样,有实际的教学研究应用的网络化实验平台。此实验平台将由控制层、现场层、管理层这三层网络组成。在此实验平台上可搭建各种PLC设备之间的通信子网。本文研究PROFIBUS现场总线通信、西门子PLC的MPI通信、工业以太网通信。在相应的各个子网下还可以实现对多种被控对象的控制实验。Programmable Logic Controller （PLC） is a digital computing electronics system designed specifically for industrial applications, replacing the relay control system. The school set up a diverse, practical teaching and research application of the network experimental platform. This experimental platform will be the control layer, the scene layer, the management of this three-tier network. In this experimental platform can build a variety of PLC equipment between the communication subnet. This paper studies PROFIBUS fieldbus communication, Siemens PLC MPI communication, Industrial Ethernet communication. In the corresponding sub-network can also be achieved under a variety of controlled object control experiments .
