Retrofit Simatic S5 to S7-400 – Aluchemie
On behalf of Aluchemie, Koster carried out the complete retrofit of an outdated Siemens Simatic S5 control system to a modern Simatic S7-400 PLC environment.
This migration was crucial to ensuring the continuity, reliability and performance of the production process. By switching to the S7-400, the installation is fully future-proof again, with improved diagnostic capabilities and higher availability.
For this project, we were commissioned to carry out the following work:
-
Engineering and migration study
-
Hardware engineering and modification of the control cabinets
-
Software conversion and rewriting of S5 code for S7
-
Panel building and component replacement
-
Extensive simulation and I/O testing
-
Installation, cutover and commissioning (including minimal downtime)
This retrofit provides stable, modern control, fully tailored to Aluchemie's demanding industrial requirements.
