Address: 1 ( I1 ), 2 ( V1 ), 3 ( P2 ), 7 ( I2 ), 8 ( V2 ), 9 ( P2 )
I1 ( I2 ) and V1 ( V2 ) contain instantaneous current and voltage, respectively, which are multiplied to yield in-
stantaneous power, P1 ( P2 ). These are two's complement values in the range of -1.0 ≤ value < 1.0, with the
binary point to the right of the MSB.
Address: 4 ( P1
Instantaneous power is averaged over each low-rate interval ( N samples) to compute active power, P1
