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.
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.
