4.5.5 Display of busbar differential currents
GUID-A271FDFD-8D47-4A1F-B45E-51DB2BD31164 v2
The differential currents are displayed for each corresponding busbar zone (1..32) (see transfer
of differential currents).

The group number 75 (0x4B) is used to display busbar differential currents and is therefore
only assigned to the Central Unit (CAA = 0).

<1> Current value <3> UI 1 1 Number of valid entries
The number of valid entries corresponds to the number of bus-bar zones and thus limited to
the range [1…32].
Each of the entries 1…32 in the group relates to a given busbar zone.
