Fieldbus reference scaling

Fieldbus references REF1 and REF2 are scaled for the DCU profile as shown in the
following table.
Note: Any correction of the reference (see section
correction on page 332) is applied before scaling.
Reference Range
REF1 -214783648
...
+214783647
REF2 -214783648
...
+214783647
Note: The settings of parameters
effect on the reference scaling.

Reference handling

Reference handling is the same for the ABB drives profile (embedded fieldbus) and
DCU profile. See section

Actual value scaling

The scaling of the integers sent to the master as Actual values depends on the
selected function. See chapter
