摘要
首先对OPC技术标准进行了简要介绍,同时对OPC技术标准在工业控制方面带来的优点作了介绍,然后对OPC技术标准中的OLE/COM技术作了较为详细的论述,详细论述了COM技术的语言无关性、可重用性和COM技术的通信机制(可连接点机制、数据通报机制和DCOM技术)。然后用Visual C++6.0环境详细介绍了为OPC客户端提供数据服务的功能。
This paper introduce the OPC standard, discusses the application of OPC standard and OPC standard, and the ad- vantages of OPC standard in industrial control are introduced in this paper. Then, the OLE/COM technology in OPC standard is discussed, and the communication mechanism of DCOM technology, which is independent of COM technology, reusability and COM technology, is discussed in detail. And then use the C＋＋ Visual 6 environment to provide data services for the OPC client.
