基于NI OPC的DCS实时网络通信实现

Implementation of DCS real-time network communication based on NI OPC

由于现场智能设备之间没有统一的接口标准,OPC为其提供公用接口。该文提出了一种采用Lab VIEW作为上位机软件,基于OPC技术,实现DCS和Lab VIEW实时通信的方法,并通过实验证明此方法的可行性和优越性。

There is no universal standard for interface between intelligent devices,OPC can provide it. The communication between DCS and LabVIEW is realized by adapting LabVIEW as upper computer software,based on OPC technology. The method is tested to be feasible and superior.
