Safety Destination Address Not Valid (F_Dest_Add)

What does 1 mean?

The configured PROFIsafe destination address (F_Dest_Add) for the safety PLC is invalid or incorrectly set. This prevents the safety PLC from establishing secure and correct communication with its intended safety partner, risking unmonitored or failed safety functions. The system's overall safety integrity is compromised if this address mismatch persists.

• The F_Dest_Add configured in the safety PLC project does not match the actual F_Dest_Add assigned to the specific safety I/O module.
• Manual entry error during the configuration of the F_Dest_Add in the PLC programming software.
• Duplicate F_Dest_Add assigned to multiple safety devices within the same PROFIsafe network segment.
• A new safety device was added or replaced, and its F_Dest_Add was not correctly parameterized in the safety PLC's configuration.

Click steps to track your progress.

1. 1

   Compare the F_Dest_Add configured in the safety PLC project with the F_Dest_Add assigned to the physical safety I/O device (e.g., read from device label or diagnostics).

2. 2

   Correct the F_Dest_Add in the safety PLC's hardware configuration to match the device.

3. 3

   Recompile the safety PLC project and download the updated configuration to the safety PLC.

4. 4

   Ensure that each PROFIsafe device has a unique F_Dest_Add within the network to avoid conflicts.

5. 5

   Perform a "compare online/offline" operation to confirm consistency between the engineering station and the PLC.
