Primary Value
Type
R The type of measurement represented by the primary value. For
Example:
Mass Flow, Absolute Pressure, Differential Temperature.

2222
gas volume flow
The measured gas volume flow value and status of available to
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 A numerical quantity entered by a user or calculated by the
algorithm.

RANGE_2 RANGE_2 RANGE_2 RANGE_2
gas volume flow
range
The High and Low range limit values, the engineering units code
and the number of digits to the right of the decimal point to be
used to display the Primary Value.
EU_100
max value
R The engineering unit value which represents the upper end of
range of the associated block parameter.
100
EU_0
min value
R The engineering unit value which represents the lower end of
range of the associated block parameter.
