TRK_SCALE
OUT_SCALE
Description
The high and low scale values, engineering units code, and number of digits
to the right of the decimal point associated with the external tracking value
(TRK_VAL).
The value (after scaling from TRK_SCALE to OUT_SCALE) applied to OUT
in LO mode.
Used to set disturbance rejection vs. tracking response action for a 2.0
degree of freedom PID.
