Development and Application of Hart OPC Server
Liu Fen · Microcomputer Information · 2009
Intelligent instruments basing on hart are wildly existing in industry control system. For perfomaning hart instruments more perfectly,a seamless integration must be implemented between instruments and control system .OPC server is an opening solution. But conventional OPC server doesn't support configuration,adjusting, management and diagnosis of instruments' parameter fully but the realtime data. For overcoming the disadvantage above, a general HART-OPC model is put forward and interpreted meanwhile this model unifies the drivers of different devices and different manufactories.At last,a opc server basing on the model applies on the press transmitter and is tested by a configuration tool.
