Table 3-6 lists the number of counts for each of the supported input channel data ranges.
Note: The engineering unit data formats represent real engineering
temperature units provided by the module to the controller. The
raw/proportional counts, scaled-for-PID and percent of full-scale data
formats may yield the highest effective resolutions, but may also require
that you convert channel data to real engineering units in your control
program.
