This paper introduces the centralized monitoring and decentralized control of the water production system of the waterworks using PROFIBUS fieldbus. The system consists of PC, industrial control machine, PL C, industrial monitors and other components. Due to the design of the system network structure integrating PROFIBUS-FMS and PROFIBUS-DP, a reasonable system redundancy technology is adopted so that the system has More powerful features, higher accuracy and reliability, lower investment and operation and maintenance costs. The actual operation results show that the system meets the design requirements, and realizes the automation of waterworks production and improves the quality of production water
