摘要
概述了OPC技术及其应用,讨论了它在现场设备间开放式数据交换,异构网段间数据共享,FCS、DCS与PLC的系统集成以及访问专有数据库中的作用。描述了工控系统如何通过OPC这一中间件技术实现集成以及不同应用软件间的即插即用。
The paper gave the overview of OPC technology and its application, discussed functions of OPC in open datainterchange among field devices, in data share among netsegments with different protocols, in system integration among FCS, DCS and PLC, in access to special database, and described how integration & 慞lug and Play 抋mong application software were implemented by OPC middleware in industrial controlsystems.
