Control system migration in a special waste incineration plant
Water
GSB Sonderabfall-Entsorgung Bayern GmbH
Aschaffenburg Germany
With its eleven sites, GSB ensures the environmentally sound disposal of industrial waste for the whole of Bavaria. Approximately 380,000 tons of material are processed safely and reliably each year under strict environmental guidelines. The incineration plant for hazardous waste in Baar-Ebenhausen forms the backbone of the area-wide disposal infrastructure.
The regular renewal of the control technology was the decisive factor for the modernization of the incineration lines including the auxiliary plants. The focus of the upgrade was on the long-term availability of the new control system. Through strategic planning, GSB wanted to secure the longest possible period for service and support as well as the supply of spare parts.
For monitoring and controlling the individual processes, the Simatic PCS 7 process control system replaced the previous system with Simatic S5 controllers.
In the marshalling cabinets, the previous Termi-Point posts were replaced by push-in terminals and the new control cabinets were connected in which a completely newly developed peripheral line from Siemens now performs its services: Simatic ET 200SP HA.
We now get a uniform marshalling level: two wires go into the field per encoder, there is no extra power supply, no additional circuit brakers or similar. This is very simple, clear and extremely diagnostics-friendly.

Saving in installation costs: due to the individual power supply of the inputs, no potential distributions are necessary, and all inputs can be wired directly to the terminals and supplied with 24 volts
Saving of engineering costs: the customer was able to build the cabinets in a standardized way according to a recurring layout
Easy troubleshooting, root cause analisys and process improvement capabilities due to comprehensive and intuitive curve and trend display in Simatic PCS 7
Very long lifecycle period for service and support as well as the supply of spare parts
