The Scaling function enables an analog input or output curve, for processes that are not linear
over the whole data range. The user can specify up to 5 analog/digital values, that will define
an input characteristic curve.
If the Scaling function is used, the offset/gain settings will become meaningless for this
channel, as the input/output will be calculated by the Scaling function given by the user.
Analog scale value and digital value outside the range selected by BFM 0 and 1 is set.
Offset/gain set value becomes error (BFM 29 b1).

The order of allocating an analog value and a digital value differs for in the input channels and
the output channel.
