Reference project

Migration of a process control system of a wastewater treatment plant

A client wants to migrate the old Contronic P process control system to Siemens PCS7 in his wastewater treatment plant. He is commissioning EXCO with:

  • The software projection and visualization with Simatic PCS7 V7.1
    • Configuration of the existing hardware components
    • Network design
    • Interfaces to other controllers
  • Setting up of the system
  • Optimization of the process
  • Coordination / consultations / schedule monitoring


With the support of EXCO, the existing basis could gradually be modernized without any breakdown of the system. This was a very large system with lots of participants and there was a major time pressure.

Technology used

Simatic PCS7 V7.1

EXCO has proven migration knowledge and lots of experience from countless migration projects.
