Units
Seconds The time constant of the first-order PV filter. It is the time required for a 63% change in the
IN value.
None A group of data that contains the current transducer value and status, the simulated
transducer value and status, and the enable/disable bit.
None The strategy field can be used to identify grouping of blocks. This data is not checked or
processed by the block.
None The revision level of the static data associated with the function block. The revision value
will be incremented each time a static parameter value in the block is changed.
None The user description of the intended application of the block.
None This alert is generated by any change to the static data.
% of OUT Range The average absolute error between the PV and its previous mean value over that
evaluation time defined by VAR_SCAN.
Seconds The time over which the VAR_INDEX is evaluated.
None The high and low scale values, engineering units code, and number of digits to the right of
the decimal point associated with the channel input value.
The XD_SCALE units code must match the units code of the measurement channel in the
transducer block. If the units do not match, the block will not transition to MAN or AUTO
To support testing, you can either change the mode of the block to
manual and adjust the output value, or you can enable simulation
through the configuration tool and manually enter a value for the
measurement value and its status. In both cases, you must first set the
ENABLE jumper on the field device.
NOTE
All fieldbus instruments have a simulation jumper. As a safety measure,
the jumper has to be reset every time there is a power interruption. This
measure is to prevent devices that went through simulation in the
staging process from being installed with simulation enabled.
With simulation enabled, the actual measurement value has no impact
on the OUT value or the status.
