1. This point is used to reconstruct neutral current values from the 1,000ths per-unit quantities given in the other points.
Multiply the particular point by this one, and divide by 1000 to get amps.
2. The VT Ratio setpoint is always reported, but is not used if a direct (i.e., without VTs) voltage wiring scheme is config-
ured. In this case the VT Ratio setpoint is ignored, and a ratio of 1.0:1 is used in the PQM.
3. This point is used to reconstruct voltage values from the 1,000ths per-unit quantities given in the other points. Multiply
the particular point by this one, and divide by 1000 to get volts. Since some SCADA systems don’t read 32 bit values,
you can also multiply the VT ratio and nominal secondary (both of which are 16 bit) in the master in cases where the
nominal primary may exceed 32767 volts.
4. This point is used to reconstruct power values from the 1,000ths per-unit quantities given in the other points. Multiply
the particular point by this one, and divide by 1000 to get VA, kW or kvar.
5. In Modbus, the current keypress is reported with format code F6. In order to fit the value into a sixteen-bit signed
value, F8 is used in DNP, with ASCII zero (49 decimal) returned when no key is pressed.
