You can parameterize the following channels depending on the DAU type:
 VCDAU and coupled CDAU at single-phase connection
 P1 to P4 Active powers group 1 of the coupled CDAU
 P5 to P8 Active powers of VCDAU and group 2 of the coupled CDAU
 Q1 to Q4 Reactive powers group 1 of the coupled CDAU
 Q5 to Q8 Reactive powers of VCDAU and group 2 of the coupled
CDAU
 FREQ1 Frequency calculated using the best signal of the first
recording group (channels 1 to 4) of the DAU
 FREQ2 Frequency calculated using the best signal of the second
recording group (channels 5 to 8) of the DAU
Powers are calculated from the corresponding current/voltage pairs V1/I1 to V4/I4 (VCDAU
and group 1of the coupled CDAU) and V1/I5 to V4/I8 (group 2 of the coupled CDAU).
