STATUS
Status
R Digital transducers, unlike their analogue versions, can detect
faults that make the measurement bad or prevent the
actuator from responding. This additional, valuable
information will be passed along with each transmission of a
data value in the form of a status attribute.

R A numerical quantity entered by a user or calculated by the
algorithm.

The high and low range limit values, the engineering units
code and the number of digits to the right of the decimal point
to be used to display the Primary Value.
