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 be-
tween 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.
