Measured-value resolution
The resolution of the analog values may differ, depending on the analog module
and its parameterization. With resolutions < 15 bits, the bits indicated by “x” are set
to “0”.
Note: This resolution does not apply to temperature values. The converted
temperature values are the result of a conversion in the analog module (see Tables
4-16 to 4-31).
