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.
Raw/Proportional Data
The value presented to the controller is proportional to the selected input and
scaled into the maximum data range allowed by the bit resolution of the A/D
converter and filter selected. The raw/proportional data format also provides the
best resolution of all the data formats.
