RW
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.

RW
The primary analogue discrete value calculated as a result of
executing the function.
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
RW
A numerical quantity entered by a user or calculated by the
algorithm.

RW
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%
RW
The engineering unit value which represents the upper end of
range of the associated block parameter.

EU_0
EU at 0%
RW
The engineering unit value which represents the lower end of
range of the associated block parameter.

RW
Device Description units code index for the engineering unit
descriptor for the associated block value.

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

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

RW
Used for the transducer status when simulation is enabled.
