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.
Description
The priority of the LO alarm.
If percentage value of transducer input fails below this, PV = 0.
The actual, target, permitted, and normal modes of the block.
Target: The mode to "go to"
Actual: The mode the "block is currently in"
Permitted: Allowed modes that target may take on
Normal: Most common mode for target
The block output value and status.
Discrete output to indicate a selected alarm condition.
The high and low scale values, engineering units code, and number of digits
to the right of the decimal point associated with OUT.
The process variable used in block execution.
The time constant of the first-order PV filter. It is the time required for a 63%
change in the IN value.
A group of data that contains the current transducer value and status, the
simulated transducer value and status, and the enable/disable bit.
The strategy field can be used to identify grouping of blocks. This data is not
checked or processed by the block.
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.
The user description of the intended application of the block.
This alert is generated by any change to the static data.
The average absolute error between the PV and its previous mean value
over that evaluation time defined by VAR_SCAN.
The time over which the VAR_INDEX is evaluated.
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
