Display of busbar differential currents
The differential currents are displayed for each corresponding busbar zone (1..32) (see transfer
of differential currents).
Table 28: Used attributes of ASDU 10 for differential current
COT
1 Spontaneous
The group number 75 (0x4B) is used to display busbar differential currents and is therefore
only assigned to the Central Unit (CAA = 0).

COD
<10> Description
<1> Current value
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.
