Byte 0 Average Line-to-Line AC RMS Voltage Vab (LSB) – this is the Least Significant Byte
of the average line-to-line AC root-mean-square voltage, Vba.
Byte 1 Average Line-to-Line AC RMS Voltage Vab (MSB) – this is the Most Significant Byte
of the average line-to-line AC root-mean-square voltage, Vba.
Byte 2 Average Line-to-Line AC RMS Voltage Vbc (LSB) – this is the Least Significant Byte
of the average line-to-line AC root-mean-square voltage, Vac.
Byte 3 Average Line-to-Line AC RMS Voltage Vbc (MSB) – this is the Most Significant Byte
of the average line-to-line AC root-mean-square voltage, Vac.
Byte 4 Average Line-to-Line AC RMS Voltage Vca (LSB) – this is the Least Significant Byte
of the average line-to-line AC root-mean-square voltage, Vbc.
Byte 5 Average Line-to-Line AC RMS Voltage Vca (MSB) – this is the Most Significant Byte
of the average line-to-line AC root-mean-square voltage, Vbc.
Byte 6 Voltage Units – an enumerated quantity used to define the scaling for output volt-
ages as follows:
0x00 – scaling for all voltages are 1 bit = 0.1 Vrms
0x01 – scaling for all voltages are 1 bit = 0.1 kVrms
Note: this scaling also applies to output voltages in messages 0xFF19
