Comments
RMS value
Absolute value
RMS value
Positive values indicate consumed current; negative values indicate generated current.
Positive values indicate consumed apparent power; negative values indicate generated apparent power.
Positive values indicate consumed active power; negative values indicate generated active power.
Positive values indicates inductive reactive power; negative values indicates capacitive reactive power.
Range:-1.0 to 1.0. Positive values indicate leading power factor; negative values indicate lagging power
factor.
Absolute value
0: no rotation recognized (not supported)
1: Clock-wise
-1: Counter clock-wise
For the Import- and Export variables an absolute value is used.For the Sum variable a positive value
indicates consumed energy; a negative value indicates generated energy.
For the Consumed and Generated variables an absolute value is used. For the Sum variable a positive
value indicates consumed reactive energy (inductive load); a negative value indicates generated reactive
energy (capacitive load).
