远程智能I/O与DCS系统的互连通信

Interconnected Communication of Remote Intelligent I/O and DCS

结合远程智能Ｉ／Ｏ 在大型火电厂的几种典型应用情况，论述远程智能Ｉ／Ｏ（ 特别是国产远程智能Ｉ／Ｏ 产品） 在大型火电厂应用时与主控ＤＣＳ系统互连通信的意义，以及实现联网通信的途径和工程设计应考虑和协调的有关通信技术约定。

In accordance with several typical application status of remote intelligent I/O in large size thermal power plants,the significance of interconnected communication of remote intelligent I/O(inparticular,domestically made remote intelligent I/O products) and main control DCS in their application in large size thermal power plants,as well as the means to realize interconnected communication and the associated communication technique agreement to be considered and coordinated in project design are discussed.
