Siemens SIMATIC S5 to S7 migration

Upgrading the mixing plant control system


  • Upgrading the central S5 PLC to S7 technology
  • Integrating the mixing plant control system into SCADA software for material and batch tracking


  • Retrofitting / replacing the S5 PLC hardware with/ by S7 hardware
  • Replacing the stand-alone intouch workstations by a server-client system with an application server consisting of redundant servers and client-workstations for the visualization of the plant processes, the operation of production orders and the database communication with SCADA

Customer benefits

  • Production is more efficient
  • Planning and processing of production orders and tracking of the resulting material movements are improved
  • Better failure protection for communication and data acquisition by redundant servers
  • Use of standard objects makes it easier to adapt changes to the automation structure of the production processes
