Configuration with T-CPU and F-CPU 
In a hardware configuration with a CPU 31xT-2DP, the safety functions of the 
SINAMICS S120 drive can be controlled with an additional F-CPU (CPU 31xF) via 
PROFIsafe. The F-CPU in this case is configured as an intelligent DP slave on the 
DP (DRIVE) of the CPU 31x T for data exchange broadcast.
