9.17.4 Group 3 data records
3.1 DAR:
● R-phase active energy wide band: 20-bit accumulator of R phase active energy wide
band
● R-phase status: 8-bit R phase status (see Tabl e 3 2 ). Bit [0] ( BIL ) represents no-load
condition for phase R active energy wide band.
3.2 DAS:
● S-phase active energy wide band: 20-bit accumulator of S phase active energy wide
band
● S-phase status: 8-bit S phase status (see Tabl e 3 2 ). Bit [0] ( BIL ) represents no-load
condition for phase S active energy wide band.
3.3 DAT:
● phase active energy wide band: 20-bit accumulator of T phase active energy wide band
● T-phase status: 8-bit T phase status (see Tabl e 3 2 ). Bit [0] ( BIL ) represents no-load
condition for phase T active energy wide band.
3.4 CF0:
● bits [27..0] of configurators (see Ta bl e 3 3 ).
