The Monitoring System of Zinc Metallurgy Leaching Process

摘要

The paper introduces the characteristics and functions of fieldbus technology through control of pH value in wet zinc metallurgy process. S7-300 PLC is master station, S7-200 PLC with communication module are secondary stations, and hardware configuration or software designing on profibus-DP are use of SETP7, monitoring software WinCC of master station monitor the system state and process data. So realize the data acquisition, information interaction, failure diagnosis and so on, and lay the foundation for the information management of Zinc metallurgy.
