LOW_CUT LOW_CUT LOW_CUT LOW_CUT
Low Cutoff Low Cutoff Low Cutoff 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.
0.0
Setting:
≥0.0
OUT OUT OUT OUT
Output Output Output Output
The primary analog value calculated as a result of executing
the function block.
-
STATUS
Status
R Digital transducers, unlike their analog 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
R/W A numerical quantity entered by a user or calculated by the
algorithm.

OUT_SCALE OUT_SCALE OUT_SCALE OUT_SCALE
Output Scale Output Scale Output Scale Output Scale
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.
100.0
EU_0
EU at 0%
R/W The engineering unit value which represents the lower end of
range of the associated block parameter.
0.0
UNITS_INDEX
Units Index
R/W Device description units code index for the engineering unit
descriptor for the associated block value.

R/W The number of digits to the right of the decimal point which
should be used by an interface device in displaying the
specified parameter.

Either the primary analogue value for use in executing the
function or a process value associated with it. May also be
calculated from the RBACK value of an AO block

R/W Time constant of a single exponential filter for the PV, in
seconds.

SIMULATE SIMULATE SIMULATE SIMULATE
Simulate Simulate Simulate Simulate
Allows the transducer analogue input or output to the block to
be manually supplied when "Simulate" is enabled. When
simulation is disabled, the simulate value and status track the
actual value and status.

SIMULATE_STATUS
Simulate Status
R/W Used for the transducer status when simulation is enabled. 0
SIMULATE_VALUE
Simulate Value
R/W Used for the transducer value when simulation is enabled. 0
