摘要
针对生产管理层中上位机须实时了解现场监控系统的情况,研究了基于OLE/COM/DCOM技术的工业控制标准OPC,着重分析了利用Visual C++语言编程以实现OPC客户端的技术。同时利用WinCC作为数据存取服务器并对其与OPC客户端的同步通信进行了研究。实践证明,该方法可靠性高,数据交换实时性好。
In order to meet the situation that the upper monitor in the production management need to realize the real-time status and need to carry on data exchange with the on-site supervisory system,the industry control criterion OPC which based on OLE,COM and DCOM is studied.The realization of the OPC client based on Visual C++ programming language is analyzed emphatically.WinCC server is used as the data access server and conducts the research to the OPC synchronous communication between the client and the server.The practice proved that this method has a high reliability and a timeliness data exchange.
