In PROFIsafe-based F-system only use S7-12xx CPUs with firmware version ≥ 4.1. 
When using a S7-12xx CPU with firmware version <4.1 in a PROFIsafe-based F-system, 
faults can occur in the PROFIsafe communication. 
If you are using an S7-12xx CPU in a PROFIsafe-based F-system, this CPU must have a 
firmware version ≥4.1.
