摘要
OPC技术为组成开放式工控系统提供了有效工具,促进了工控系统朝着开放的方向发展。本文在简述OPC技术及其应用背景的基础上,讨论了OPC技术在信息集成中的作用:通过OPC接口实现对现场实时数据的一致访问,实现不同应用软件间的即插即用,实现控制系统的集成与数据共享。
OPC (OLE for Process Control ) provided effective tool for composing open control system, accelerated their development forward open direction. The paper gave the overview of OPC technology and its application, described OPC action in information integration. Real time data was conformably accessed by OPC interface. Plug and play for different software, system integration and data share were implemented.
