Study Of The Central Control Of The Coal Selection Factory Based On Indusrial Ethernet And Profibus-Dp

The central control of the coal selection factory is to control the process in a fixed program, such as the start, stop, and failure of the machine which is connected to each other .This passage, aiming at the practical control demand, has developed the process control system which is based on the industrial Ethernet and Profibus-dp.This passage has introduced the demand for the central control system according to the working procedures of coal selection, illustrated the main equipments in brief, and also studied the procedure of coal selection, which has supplied enough preparation for the development of the network control system. What's more, this passage has illustrated the structure, composition, characteristics, and the S7-industrial communication networks, and also explained the communication protocols, the communication modes, the hardware configuration of the developing platform and the software we used .Aiming to the software design and function completion of the network control system, this passage has illustrated the hardware configuration, network configuration, the downloading and programming of the hardware and also introduced the communication configuration between Wincc and PLC, and the picture configution.
