基于Visual C#的OPC客户端实现

Implementation of OPC Client Based on Visual C#

OPC是连接数据源(OPC服务器)和数据的使用者(OPC应用程序)之间的软件接口标准。这里以C#为开发工具,按照OPC技术的规范标准,将OPC技术应用到虚拟仪器显示组件中。具体实现了OPC客户端数据访问服务器的过程,接口步骤及其读写数据的方法,并根据OPC服务器提供的数据,最终在虚拟仪器显示组件中生成了虚拟的正弦波、方波、锯齿波、三角波等。

OPC is the software interface standard between data sources （OPC server） and data users （OPC application）. Based on OPC technology standards, the virtual instrument is proposed and is applied to the virtual instrument display components by using C# language. The OPC client data access server process,the method of write and read data and interface steps are realized. According to the data provided by OPC server, finally, the waveform of sine, square, sawtooth, triangle are generated in the display eomponents of virtual instrument.
