VALUE VALUE VALUE VALUE
Density
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
R A numerical quantity entered by a user or calculated by the
algorithm.

SECONDARY_ SECONDARY_ SECONDARY_ SECONDARY_
VALUE_RANGE VALUE_RANGE VALUE_RANGE VALUE_RANGE
Density Range
Defines the ends of the SECONDARY_VALUE, the units of the
SECONDARY_VALUE, and the decimal point position (number
of significant digits to the right of the point). The engineering
units must match the units selected in the parameter
XD_SCALE of the Analog Input Block that reads the channel
with this value.
-
EU_100
max value
R The engineering unit value which represents the upper end of
range of the associated Block Parameter.
5000 kg/m³
EU_0
min value
R The engineering unit value which represents the lower end of
range of the associated Block Parameter.
0.05 kg/m³
UNITS_INDEX
Units Index
R/W Device Description units code index for the engineering unit
descriptor for the associated block value.
