In the user data variant FE
H
(254) the measured value for the current L1 is stored in Byte 2 +
3. The current is supplied by the module as a 16-bit-fixed-point number in the value range
from 0 to 65535 in the unit 1 mA. In addition the scaling factor for the current L1 has to be
considered additionally. The module supplies the related scaling factor in Byte 24.
The actual value for current L1 is calculated as follows:
Actual value for current L1 = Current L1 x 10
