建立新型开放的自动化网络

A Construction of New Automation Networks of Openness

本文指出网络开放的重要性和意义，从结构上、设备上和网络的相互关系上分析了开放性，在此基础之上，提出一个新型的工业自动化三层模型，作为建立新型自动化网络的基础。按此新三层模型建立的自动化网络，就是一个简单、实用、开放的网络，以保证工业控制系统比较理想地运行。

This paper points out significances in the networks of openness,and analyses opennes on the basis of architecture,deveice,and network perspectives. Upon these,it puts forth a new three - layer model in industrial automation,as a foundation for new automation networks. The automation networks made by the model are simple,practical and open ones in order to ensure an ideal operation of industrial control systems.
