首发时间:2013-09-05
摘要:OPC技术的产生,使得各个数据源能在工业控制环境中进行灵活地通信。本文以地铁转向架空载试验台为例,设计了通过OPC与下位机西门子S7-200 PLC进行通讯的上下位机测控系统。开发了以Visual Basic为平台的OPC客户端程序,通过使用不同的OPC通讯方式,实现了对OPC服务器数据的读取。整个测控系统运行稳定,数据读取实时性较强。

Application of the OPC Technology in the No-load Test Platform of the Metro Bogie
Abstract:The generation of the OPC technology makes each data source communicate flexibly in the industrial control environment. This paper takes the no-load test platform of the metro bogie as an example to design a lower and upper computer measurement and control system which is consist of IPC and PLC by the OPC technology. The OPC client is developed based on the platform of Visual Basic. By using the different communication mode, it is realized to access the OPC server data.
Keywords: Automatic control technology OPC VB Test Platform of the Metro Bogie
