And the Profi

3、bus is a kind of Fieldbus broadly used in many situations of process control of industry such as automation of processing, automation of machining and automation of building. According to the actuality of the studied water station, the thesis combine the advanced Fieldbus technique, Ethernet and the

4、 traditional machine and electric technique together, and use them to design the supervise controlling system of the water station. During the designing of the electricity control system, the thesis used the mode that made up of monitor system and control system, formatted a network that is combined by far concentrates control system and nearly control system. The monitor system chooses the functional monitoring softwarethe king monitor and the man-machine interface, which operated conveni
