Safety Destination Address Not Valid (F_Dest_Add)

ABB · AC500 Function Block Libraries

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Perform a controlled restart of the safety PLC after making any changes.

  2. 4

    If the error persists, consider replacing the safety PLC module.
