The following 3 parameters can be changed, but normally
it is only necessary to change the F_Dest_Add parameter:

Watchdog time
The watchdog time setting depends on the speed of the
PROFINET connection and the number of devices.
Valid range: 67-65535 ms.
Default value: 150 ms.
If the safety option does not receive a new valid PROFIsafe
telegram within this time, the safety option enters the safe
state. The watchdog time is configured to a value that is
long enough to avoid false alarms and short enough to
detect errors in communication. The formula for
calculating the minimum watchdog time:
F_WD_Time=2 * BT + HAT + DAT
•
•
•
Use the watchdog time to calculate the safety function
response time (SFRT) for the system. For more information,
see the PROFIsafe profile description at www.profibus.com.
