| Abstract: | Process control system based on two-level networks for experiment equipment is studied in this paper. The Profibus is used for the first floor and the industry Ethernet is used for the upper floor,the controlled object is a experiment equipment imitating electrothermal boiler. The constitution and work principles of experiment equipment are analyzed and the technologic flow diagram is obtained. The S7-400 series PLC is selected as the field control and PC is adopted for up machine. Then,Fuzzy-PID control experiment is taken as an example for exhibiting this system. This system can not only set up the basic experiment about the process control,but also benefit for the experiment about the comprehensive type and design type. |
