概述了OPC技术的概念及其应用,讨论了TRACE MODE使用OPC技术在现场设备间开放式数据交换,异构网段间数据共享中的作用。介绍了TRACE MODE作为OPC服务器和OPC客户端的设置方法。最后介绍了TRACE MODE中的 OPC通讯方式。其必将在大型SCADA系统中得到越来越广泛的应用。
The concept of OPC technology and its application are summarized. The role of TRACE MODE in using OPC technology to open data exchange between field devices and data sharing among heterogeneous networks is discussed. Describes how to set up TRACE MODE as an OPC server and OPC client. Finally, we introduce the OPC communication in TRACE MODE. It is bound to be more and more widely used in large SCADA systems.
