This bit is set to indicate that this is the third type of electrical
parameter out.

This bit is set to indicate that this is the third type of electrical
parameter out.
DATA2:
Real Power sensed by the DSLC.
P = DATA2 x CT_RATIO x PT_RATIO
DATA3:
Reactive Power sensed by the DSLC.
Q = DATA3 x CT_RATIO x PT_RATIO
DATA4:
Apparent Power sensed by the DSLC.
S = DATA4 x CT_RATIO x PT_RATIO
DATA5:
Generator Frequency sensed on the A-Phase voltage input. It is
scaled by 100 for resolution.
GEN_HZ = DATA5/100
DATA6:
Bus Frequency sensed on the bus voltage input. It is scaled by
100 for resolution.
BUS_HZ = DATA6/100
DATA7:
Discrete Inputs actually seen on the DSLC terminal strip.
