Frequently asked questions
Siemens cancelled part of the Comfort Panel range — what does that mean for me?
Siemens has issued cancellation notices covering the larger Comfort Panels, which pushes replacements toward lead time and migration projects. Repairing your existing panel keeps the exact validated hardware and project in service.
Is my WinCC project safe?
Yes — it is stored in flash / SD and untouched by the physical repair. If you have the TIA Portal source, keep it archived as normal practice, but the repair does not require it.
