摘　　要：OPC是现场总线必不可少的系统集成工具。针对PROFIBUSPAOPC服务器的研究不足、开发复杂的情况,本文提出了一种PAOPC服务器的开发模型,并给出了接口设计。然后按照设计进行开发,搭建了PROFIBUSPA硬件平台,配置了软硬件并建立了OPC服务器的开发环境。为PA总线的访问开发了OPC服务器使用的驱动程序。在此基础上开发了PROFIBUSPA的OPC服务器。利用常用控制软件对开发的服务器进行了测试。测试结果表明PAOPC服务器功能齐备、运行稳定。现在正准备在某化工厂进行实际应用。OPC is a system integration tool which is necessary to field bus. The study an PROFIBUS PA OPC server is not enough and it is hard to develop such a server. So this paper introduced a PA OPC server＇s developing model and then gave out the interfaces design. According the design, we set up PROFIBUS PA hardware platform, configured software and hardware and completed developing environment for OPC server. Drivers were developed for OPC server to access PA field bus. Then a PROFIBUS OPC server was built based on them. Commonly used control software was used to test the server. Test results showed that the PROFIBUS PA OPC server has complete functionalities and runs stably. The server will be used in a chemical plant in next step.
