Issue:
Does Schneider Electric have the PFHd value for 30 years life-cycle of the Preventa XPSMCM Safety Controller?

Resolution:
According to the standard IEC13849 the calculation is always based on 20 year life-cycle, so we have no idea how the value might change.
There is no simple "rule of thumb" to use to get a new value.

In general the PFHd value was calculated based on different aspects such as
- used components
- used schematic
- used HW structure
- ...

PFHd is expected to be worse for longer life time but we cannot determine the exact value without a complete "re-investigation" in the product.
