5.1 Representation of the values for analog input channels
Measured value resolution
The resolution of the analog values may differ, based on the analog module and module
parameters. At resolutions < 15 bits, all bits identified by "x" are set to "0".
Note
This resolution does not apply to temperature values. Converted temperature values are the
result of a conversion in the analog module.
