Byte 0 Generator Power Factor Sense – this is the direction of the generator power factor
as given by the following enumeration:
00 – Lagging Power Factor
01 – Leading Power Factor
Byte 1 Unused
Byte 2 Generator Real 3-phase Power (LSB) – this is the Least Significant Byte of the
generator real power. (1 bit = 1 W)
Byte 3 Generator Real 3-phase Power (MSB) – this is the Most Significant Byte of the
generator real power. (1 bit = 1 W)
Byte 4 Generator Apparent 3-phase Power (LSB) – this is the Least Significant Byte of the
generator total real power. (1 bit = 1 VA)
Byte 5 Generator Apparent 3-phase Power (MSB) – this is the Most Significant Byte of the
generator total real power. (1 bit = 1 VA)
Byte 6 Generator Reactive 3-phase Power (LSB) – this is the Least Significant Byte of the
generator total real power. (1 bit = 1 VAR)
Byte 7 Generator Reactive 3-phase Power (MSB) – this is the Most Significant Byte of the
generator total real power. (1 bit = 1 VAR)
