摘要
介绍了OPC技术产生的背景 ,通过指出传统技术的缺陷引出OPC技术 ,说明了OPC技术的优势所在。接着简单介绍了OPC规范 ,并描述了它的主要特点与发展状况 ,进一步说明了开发OPC应用程序的必要性。重点介绍了OPC服务器程序设计的理论基础和设计方法 ,其中包括它的核心技术COM DCOM技术的介绍 ,OPC服务器程序设计总体框架的介绍。最后对OPC服务器开发方式进行了分析与比较 ,说明了使用ATL和MFC开发COM组件的优缺点。
The background and the advantage of OPC technique are discussed in the paper.Through pointing out the disadvantage of tradition technique, OPC protocol ,feature and development status of OPC protocol are also described.So it's necessary to develop OPC applications,but it isn't easy.This paper emphatically introduces the theories foundation and the method of designing OPC Server, among them including the introduction of technique COM/ DCOM of its core and the introduction of the total frame.Finally the paper analyses and compares the development method towards OPC server,and points out the weakness and advantage of two development tools such ATL and MFC.
