Project Background
This project is the sewage treatment self-control system of a certain sewage treatment plant. The construction scale is 48000m3/d. With the increasingly prominent problems of domestic production and domestic water pollution, as well as the government's increasing efforts in environmental protection, the requirements for automatic control systems in sewage treatment are also becoming higher and higher. Shijiazhuang Sewage Treatment Plant has selected Siemens' new type after considering various aspects of the previous sewage self-control systemS7-1500+The WINCC combination method realizes functions such as data collection, device control, and report statistics for the entire system.

Solution
1. The control system adopts S7-1500 control system, which completes the control of the entire system through PN bus and ET 200SP/ET200MP slave station
2. Two sets of Siemens Wincc are used for monitoring at the upper level
3. The total number of I/O points in this system is over 600
4. The system communication adopts a redundant fiber optic ring network, greatly improving the communication reliability of the system

Project Highlights
In this system, the use of S7 1500 highlights the powerful performance advantages of this series of PLC products in terms of product processing speed, module accuracy, powerful PROFINET networking capabilities, fault diagnosis capabilities, and many other aspects; TIA Botu software can save technicians a lot of time in efficient programming and debugging, making the debugging process smoother; The WINCC DataMonitor function makes the implementation of related report functions more convenient and more in line with the actual needs on site.

Overall, S7 1500+Boruto+WINCC DataMonitor provides a good configuration solution for the sewage treatment industry.
