Note – Powers are sent out as 32 bit signed integers, expressed in W (or var/VA)
with 2 decimals. This means that the maximum power possible to express is
approximately ±21 MW. If the power is higher than that the user is adviced to read
power from the DMTME mapping instead, where the scaling is in W without
decimals.
Harmonics
Inputs and
outputs
Harmonics are mapped in one register each, starting with THD and then
followed by 2nd, 3rd, 4th harmonic and so on.
All registers in the following table are read only:
