1.3 Analog Data
The user must manually associate analog data to a register number. The following
analog data can be selected:

RMS value of voltage and current circuits (any phase);

Voltage and current synchrophasors (any phase, angles are sent in degrees
units);

Frequency of voltage and current circuits;

Positive sequence of voltage and current circuits;

Negative sequence of voltage and current circuits;

Imbalance of voltage and current circuits;

Total harmonic distortion of voltage and current circuits;

Apparent combined power of power circuits;

Apparent fundamental power of power circuits;

Active fundamental power of power circuits;

Reactive fundamental power of power circuits;

RMS value of transducer channels.
1.4 Digital Channels
All digital channels are reported in groups of 8 channels. A register data is composed
of 16-bit data where the least significant bit represents the state of the first digital
channel of the group. The user must manually associate a digital group with a
register number.
