0: The associated alert may clear when the priority is changed
to 0, but it will never occur.
1: The associated alert is not send as a notification. If the
priority is above 1, then the alert must be reported.
2: Reserved for alerts that do not require the attention of a
plant operator, e.g. diagnostic and system alerts. Block alarm,
error alarm and update event have a fixed priority of 2.
3...7: Increasing higher priorities - advisory alarms.
8...15: Increasing higher priorities - critical alarms.

LOW_CUT LOW_CUT LOW_CUT LOW_CUT
Low Cutoff
R/W Limit used in square root processing. A value of zero percent
of scale is used in block processing if the transducer value
falls below this limit, in %of scale. This feature may be used to
eliminate noise near zero for a flow sensor.

OUT OUT OUT OUT
Output
R/W The primary analogue discrete value calculated as a result of
executing the function.
Note: Note: Note: Note:
W = Writeable only by setting "OOS" in MODE_BLK
-
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 R/W A numerical quantity entered by a user or calculated by the
algorithm.
-
OUT_SCALE OUT_SCALE OUT_SCALE OUT_SCALE
Output Scale
R/W The high and low scale values, engineering units code and
number of digits to the right of the decimal point to be used in
displaying the OUT parameter and parameters which have the
same scaling as OUT.
-
EU_100
EU at 100%
R/W The engineering unit value which represents the upper end of
range of the associated block parameter.
