ReferenceSelector (01.014) is automatically set up when a new drive configuration is programmed (see DriveConfiguration (11.034) ).

ReferenceSelectedIndicator (01.049) is equal to ReferenceSelector (01.014). If ReferenceSelector (01.014) = 0 then ReferenceSelectedIndicator (01.049) is
controlled by the reference select flags as shown below. The higher numbered flags have priority over the lower numbered flags.
