Note: The engineering units 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
5
Type B and C thermocouples cannot be represented in engineering units x 1 (°F) above 3276.7°F. Software treats
it as an over range error.
6
When millivolts are selected, the temperature setting is ignored. Analog input data is the same for either °C or °F
selection.
