tween DP and FF end.
FF segment runs independently of
PROFIBUS. The schedule has been
downloaded. CiF runs with the most re‐
cently downloaded FF configuration.

After startup:
Compact FF Link is operating.
There is a connection to PROFIBUS.
At least one FF device is not available
at the FF segment or is not configured
(e.g. with factory settings).
Evaluate the diagnos‐
tics of the Compact
FF Link and check
the reported FF devi‐
ces.

the DIP switch. See
Redundancy: Passive channel
The Compact FF Link is a passive chan‐
nel of the redundant Compact FF Link
and is ready to assume the active chan‐
nel.
At least one FF device has an incorrect
Physical Device (PD) tag.
Evaluate the diagnos‐
tics of the Compact
FF Link and check
the reported FF devi‐
ces.
The settings that are downloaded to the
integrated field device coupler of the
Compact FF Link do not match the hard‐
ware configuration
Check the position of
the "RING" DIP
switch.
Check the configura‐
tion of the integrated
field device coupler in
the project.
There is a problem on the FF segment
(wire break, short circuit)
Check the wiring of
the FF segment.
