The Application of PROFIBUS Technology in the Fengchan River Project´s Electronic Control System Reform

This paper is about the application of the PROFIUBS technology which is used in the electrical control system of Fengchan River´s purification project in Tianjin. The Profibus-dp card is designed which can convert the data format from PROFIBUS protocol to MODBUS protocol. The system taking IPC(Industrial Personal Computer) as the master station, using the configuration software to realize centralized control and management, controlling multigroup Profibus-dp board as the slaver station by the CP5611 card and using optical fiber converter to realize remote communication by the optical fiber is to monitor the input and output devices in the field and ensure the four pump wells and nurseries to realize centralized management and monitoring.
