摘要
本文首先对SCADA(Supervisory Control And Data Acquisition,数据采集与监视控制系统)系统和OPC(OLE for Process Control,用于过程控制的OLE)技术进行了简要的介绍,在SCADA系统功能要求的基础上提出了OPC在该系统中的应用方法,阐述了OPC的技术优势。然后描述了OPC服务器的主要接口函数与客户端的设计流程,最后本文提供了OPC服务器与客户端在SCADA系统中的运行结果。
Firstly, this paper briefly introduces the system of SCADA （Supervisory Control and Data Acquisition） and the technology of OPC （OLE for Process Control）, and shows the application and advantages of OPC based on SCADA system function requirement. Secondly, this paper provides the main interface functions of OPC Server and the design of OPC Client. Finally the operational status of OPC Server and Client in SCADA system is showed.
