Measurement Data Format
The measuring values are transmitted as Signed32.
Since the controller has a resolution of 24 bit, not all 32 bits are required. 0x0 = 0 % of
measuring range corresponds consequently to 0xFFFFFF = 100 % of measuring range.
The measuring range can be read from the channel info objects 2020h to 2027h (range
and unit). Here is also the minimum and maximum value, which the Signed32 measuring
value can take (data format zero value and data format end value).
