摘要
从系统构成和通信软件两方面介绍了一种基于RS -4 85网络的集散型控制系统。该系统的RS -4 85网络由1台工控机和 10台可编程控制器构成。工控机通过RS -4 85网络控制 10台独立的 3自由度数控液压小车。本文提出了一种RS -4 85网络通信协议。
A total distributed control system based on RS-485 network is presented from system composition and communication software in the paper. RS-485 network in the system is composed of one industrial control computer and ten programmed logical controllers. The industrial control computer controls ten independent numerical controlled hydraulic vehicles in three degrees of freedom. A RS-485 network communication protocol is designed in the paper.
