FCS：领域自动化底层技术中的数字通信

FCS:Digital Communication in the Low Level Technique of the World Automation

本文讨论了工业数字通信对领域自动化底层技术的影响及其变革，重点研究了现场总线网络的通信方式及ＦＣＳ的体系结构。针对工业数字通信的层次化概念和工业环境对数字通信的需求，采用ＬＡＮ技术分析了领域自动化中的通信问题，在总结了国际上若干现场总线网络在领域自动化中的应用之后得出结论：工业数字通信必将导致由物流控制向数据流控制的进化。

This paper discusses the digital communication that affects and changes the low level technique of the world automation. It mainly researches on the communication mode of fieldbus networks and the architecture of FCS. In accordance with the concept of levelization of the industrial digital communication and requirements of the environment, it analyzes the communication in the world automation with LAN tehnolopy. After summarizing the applications of fieldbus networks in the world automation, it draws one conclusion: the dagital communication in industries is sure to lead to the evolution that is from the mass control to the data flow control.
