分布式工业控制系统通信功能的研究

Study on a Communication Function of a Distributed Control System in Industry

本文在提出由IBM—PC/XT微型机作为上位机,若干台SR—400可编程序控制器作为下位机所组成的分布式工业控制系统方案基础上,对系统的关键——通信软件的设计思想和设计方法作了比较深入的探讨.

Based on a distributed control system with master(IBM-PC/XT)-slave(SR-400pc)computers,a key problem of the system-the design of communication software is profoundly discussed in the paper.
