Control of the Basic Functions via PROFIsafe (CU310-2 and CU320-2)
The following table lists the response times from receiving the PROFIsafe telegram at the
Control Unit up to initiating the particular response.

The specified response times involve internal SINAMICS response times. Program run times
in the F host and the transmission time via PROFIBUS or PROFINET are not taken into
account. When calculating the response times between the F-CPU and the converter, you
must take into account that faults in the communication can result in a safety function only
being selected after the PROFIsafe monitoring time (F_WD_Time) has expired. The
PROFIsafe monitoring time (F_WD_Time) must also be included in the calculation when an
error occurs.
