Safety Telegram & F-
I/O Data of the Safety
Telegram
The value must be the same as the Safety telegram in the Advanced safety option board. F-I/O Data
must be mapped as described in chapter Data mapping for PROFIdrive on PROFIsafe.
The following PROFIsafe-related parameters cannot be edited in the Advanced safety option board. They must have the same value
in the safety PLC communication to the option board over PROFIsafe. The values of the Table 47 are defined in the fieldbus GSD
description file that is provided for the fieldbus option board by VACON

7.1.5.2 PROFIsafe Watchdog Time
Use the F-Parameter F WD Time to determine a watchdog time for the communication between F-Host and F-Device.
The minimum watchdog time has 4 parts:
DAT = Device Acknowledgment Time. F-Device receives a frame, processes it, and prepares a new frame to be sent.
Bus = The transfer time of the frame from the AC drive to F-Host.
HAT = Host Acknowledgment Time. F-Host receives a frame, processes it, and generates a new frame.
Bus = The transfer time of the frame from F-Host to the AC drive.

Illustration 71: The Parts of the Watchdog Time
It can sometimes be difficult to determine the bus transfer time that is used to calculate the watchdog time. For more information
on the cycle times, see the user guide of the used fieldbus.
Use this formula to calculate the F WD Time:
FWDTime = DAT + HAT + 2 × BT
