Abstract:
Combiningthe characteristics ofPLCand WINCCand the actual control requirement ofautomatic reagent-adding system of circulating water in the water factory,the PLC of SIMATICS7-200 series and WINCC configurationsoftware applied to the technologic design and implementing technology of online-monitor for the water quality ofindustrial circulating water is introduced.The system composition and the requirement of technical control areanalyzed firstly,and,then,the configuration of hardware and software and control strategy are described concretely.This system has been put into operation in the water factory.It is proven that the man-machine interaction of the control system is good,its reliability is high,and the ability of anti-jamming is strong.It has satisfied the requirement of supervising the water quality of modern industrial circulating water.
