FIELD_VAL FIELD_VAL FIELD_VAL FIELD_VAL
Field Value Field Value Field Value Field Value
R Raw value of the field device in percent of the PV range, with a
status reflecting the transducer condition, before signal
characterization (L_TYPE) or filtering (PV_FTIME).
-
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.

GRANT
Grant
R/W Depending on the philosophy of the plant, the operator or a
higher level device (HLD) or a local operator's panel (LOP) in
the case of "Local", may turn on an item of the "Grant"
attribute - "Program, Tune, Alarm or Local".
