基于OPC的国产DCS与PLC的集成及应用

Integration and Application Between Domestic DCS and PLC Based on OPC

研究设计了和利时HOLLIAS-MACSV DCS与西门子SIEMENS PLCS7-300基于OPC的网络通信方案,详述了DCS的组态设计,该方案应用于火电厂蒸汽吹灰控制系统中,将DCS与PLC构成一个可以交换信息的整体,实现了由DCS集控运行人员监控吹灰控制系统的运行,减少监控点,节约了电厂的运行成本。

This paper studies and designs the communication scheme of HOLLIAS—MACSV distributed control system（DCS） and SIEMENS programmable logic controller（PLC） based on OPC . Configuration specification of DCS and applications in soot blow control system of power plant are also described in this paper. DCS and PLC are designed as a whole, which can exchange information, and achieve monitoring of the soot blow control system of power plant with fewer monitoring points and less cost, by operation of DCS.
