Whether the measured values "Residual Current" and "Neutral Current" are suppor-
ted depends on the respective device model. For measured values such as "Neutral Cur-
rent", which are independent of the phase, the same value is returned for all phases.
DC Energy Sensors:
With the EPC 8291 / 8290 devices, the voltage and current of the individual banks and
voltage sources can be read out. The measured values of the energy sensors are re-
turned as signed 16-bit integers. The following formulas are available for the address (the
values for Bank and PowerSrc start at zero):
Bank: Bank * 2 + Offset
Power Source: PowerSrc * 2 + Offset
