When millivolts are selected, the temperature setting is ignored. Analog input data is the same for either °C or °F selection.

Type B, C, and D thermocouples cannot be represented in engineering units x 1 (°F) above 3276.7 °F. Software treats it as an over-range error.
Thermocouple or millivolt input data reside in I:e.0 to I:e.3 of the SLC
controller's input image file (where e is the slot number assigned to
the module). The values depend on the input type and data format
that you select. When an input channel is disabled, its data word is
reset (0).
