一种OPC客户端实现WinCC数据转存

主要介绍了用Visual Basic设计一种OPC客户端,该客户端符合OPC标准。通过该客户端成功地实现了Visual Basic与西门子WinCC组态软件的OPC服务器进行通讯（该软件内嵌OPC支持）,完成它们之间的动态数据交换,并在Visual Basic中利用其ADO数据库接口,把WinCC组态中监控到的数据实时存储到SQL数据库中,从而解决了WinCC组态软件中实时数据转储到标准数据库的难题,为用户分析调用监控数据提供了更有效的途径,最后给出了具体的实现步骤和关键程序。

OPC Client Implement WinCC Data Dump

This paper describes using Visual Basic to design a OPC client,the client in line with OPC standards.Through which the client has successfully achieved a Visual Basic and SIEMENS WinCC Configuration Software OPC server communication （the software embedded OPC support）,the completion of the dynamic data exchange between them,and in Visual Basic,to use its ADO database interface,WinCC configuration to monitor real-time storage of the data into the SQL database,so as to solve the Wincc configuration software in real-time data dumps to the standard database problem,call the monitoring data analysis for the user to provide a more effective way.
