Command 35: Write Primary Variable Range Values
In the DVC5000, the Primary Variable is defined to be the measured Valve Travel.
This command is used to write the ranging values reported in Command 15. It sets the engineering units to be
reported with 0% and 100% of calibrated travel.
This command will only be accepted when the DVC5000’s Instrument Mode is in the “Out of Service” condition and
will be rejected if Write Protection is in effect.
