Sewage treatment plant (>120,000 EW)
KIMA was responsible for implementing the complete electrical and automation technology for, among other things, six different plant sections within a short period of time. These processes were completed in some cases in parallel and during ongoing operation. This included:
1 x Revitalization (six basins)
1 x Rain overflow basin (RÜB)
1 x Discharge pumping station
1 x Intermediate pumping station
2 x Wastewater pumping station
Control system:
- 7 x SIMATIC S7-300 CPU 315-2DP/PN
Operating and monitoring system:
- Extension of the process control system realized by KIMA (WinCC/Step7)
- 2 x redundant WinCC servers
- 10 x WinCC clients
- 2 x Remote access/stand-by
- 3 x Acron operating stations
- 1 x SIMATIC ST7CC
- 2 x TIA Panel TP2200 TIA Siplus
- 3 x TIA Panel TP900
Bus systems:
- Profinet:
- Connection of decentralised peripheral equipment
- Connection to the frequency converter
- Plant bus:
- Connection between the PLC and servers
Noteworthy aspects:
- Operating concept independent of the PLC
- IT security: including segmentation and secure communication between remote stations via ScalanceS
- Radio link or SHDSL modems for TCP/IP-based integration of the remote operating stations
- Explosive areas
- Measurement technology
- Lightning protection systems (internal and external)
