PLC control system design of steel sculpting production line using PROFIBUS-DP
Yuan You-xin , Lan Yan, Lvlin （School of Automation, Wuhan University of Technology, Wuhan，Hubei 430070） Abstract: The paper introduces the technical reconstructing design of PLC control system about steel sculpting production line. PROFIBUS-DP process technologies are adopted to achieve data exchange and distribution control between the main station and substation. Through central monitoring control by main frame, various functions are carried out, such as visual operating interface between man and machine, communications, network and so on. The design can be applied in other industrial control systems.
Key words: PROFIBUS-DP; sculpting production line; programmable logical controller (PLC)
