Automation of a sewage treatment plant
with pumping station and stormwater overflow tank
with pumping station and stormwater overflow tank
Symbolic technical representation of a sewage treatment plant
Uniform control of the complete wastewater network
• SIMATIC PCS 7 process control system in the sewage treat-
ment plant
• SIMATIC PCS 7 TeleControl with SIPLUS RIC telecontrol tech-
nology on the basis of the IEC 870-5-104 protocol
• Combination of process control at one operator station
(PCS 7 OS client)
• Compliant process control with uniform faceplates, alarms,
trends etc.
Cost-effective RTUs exactly matched to the respective unit
• S7-300 controller for pumping station
• ET 200S with integral CPU for stormwater overflow tank
• ET 200S with integral CPU for stormwater overflow tank
Secure communications
• Protection of telecontrol network by SCALANCE S613
industrial security module
• Application of GPRS technology
Reporting and archiving in compliance with
