Abstract

The realizing process of series communication with OVATION system has been analysed in detail. In retrofitting distributed control system (DCS) of unit No.2 at Huaneng Luohuang Power Plant

data communication among different DCS. as well as data exchange between OVATION DCS and field PLC has been successfully realized by using MODBUS communication protocal. Both the retrofitting purpose of all-round upgrading the main unit control system and of retaining usable field control facilities have been achieved

saving retrofitting cost for the said system.
