用DCOM技术实现DCS与其OPC服务器的通信

本文介绍了如何使用DCOM技术将DCS改造成进程外COM服务器,为DCS提出了一种简单的对象模型并设计了较通用的COM接口,利用该接口实现了DCS与其OPC服务器的通信。该接口具有良好的抽象性,很好的隔离了DCS及其OPC服务器,使得OPC服务器不再依赖于DCS的具体实现。

This paper introduced how to change DCS to out-of-process COM Server using DCOM technology,and present a simple object model and a general COM interface for DCS,to realize the communication between DCS and its OPC server based on that interface.With good abstractness,the interface isolates DCS from its OPC server so that the OPC server no longer depends on the concrete implementation of DCS.
