6.2.3 FC REF_MODE
With the FC REF_MODE you start the seek-reference-point mode. The FC
executes the following actions:
 Sets the seek-reference-point operating mode.
 Controls the seek-reference-point operating mode.
 Reads the check-back signal (for example, actual value). The read values
are saved by the FC in the channel DB (CHECKBACK_SIGNALS).
