The data structure complies with the LVSG (Low Voltage Switchgear) profile
of PNO (PROFIBUS User Organization) which defines 2 bytes of output data.
All functions of the second byte are not supported. A dummy byte (byte 1) is
therefore required to ensure that the device is compatible with the LVSG pro-
file. An additional byte is provided for resetting the energy value.
