R The measured value and status available to the Function
Block.
-
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.
-
VALUE
Value
A numerical quantity entered by a user or calculated by the
algorithm.
