PLC & HMI Retrofits
Modernise obsolete Siemens panels with Unified HMIs
We replace discontinued Siemens operator panels with modern Unified HMIs, migrate existing projects, and rebuild screen logic where the original source code is no longer available.
How a retrofit runs
From evaluation to commissioning
01
Evaluate the panel
We record the installed Siemens hardware, its availability, and the production risk of leaving it in service.
02
Migrate the project
Existing projects are moved onto a modern Unified HMI, keeping operator screens and tag structure familiar where possible.
03
Rebuild the code
Where source code is missing, we reconstruct screen logic from the running system and verify each function with the team.
04
Commission on site
We test the new panel against the live process, plan the changeover window, and hand over documentation and backups.
