Development of OPC Server Based on WIA-PA
-
摘要: 论述了基于WIA-PA的OPC服务器的开发流程及具体实现步骤；以OPC客户端软件连接温度传感器为例，介绍了基于WIA-PA的OPC服务器将工业现场仪表采集的数据实时显示在上位机上的实现方法。测试结果表明，该OPC服务器能够规范化地添加现场设备及更新设备数据，并能使OPC客户端实时获取现场测控数据。Abstract: The paper discussed developing process and concrete realizing steps of OPC server based on WIA-PA, and introduced how the OPC server sent data collected by meters in industrial field to upper computer for real-time display by an example of connecting OPC client software with temperature sensor. The testing result showed that the OPC server can add field devices in normalization, update data of devices, and make OPC clients obtain monitored data real-timely.
