Table 14: Analog Input block parameters
The revision level of the static data associated with the function block. The revision
value is incremented each time a static parameter value in the block is changed.
The user description of the application of the block.
It is used to identify grouping of blocks. This data is not checked or processed by the
block.
The identification number of the plant unit. This information may be used in the host
for sorting alarms, and so on.
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
This parameter reflects the error status associated with the hardware or software
components associated with a block. It is a bit string, so that multiple errors may be
shown.
The process variable used in block execution.
The block output value and status.
A group of data that contains the current transducer value and status, the simulated
transducer value and status, and the enable/disable bit.
Elements used to display the value obtained from the transducer block. The elements
are:

High and low scale values (EU_100 and EU_0).

Engineering units to display the value (UNITS_INDEX).

Decimal places to display the value (DECIMAL).
The high and low scale values, engineering units code, and number of digits to the
right of the decimal point associated with OUT.
Normally, the operator has permission to write to parameter values, but Program or
Local remove that permission and give it to the host controller or a local control
panel.
Allows the selection of input/output options used to alter the PV. Low cutoff enabled
is the only selectable option.
Helps select options for status handling and processing. The supported status
options for the AI block are Propagate Fault Forward Uncertain, if Limited Bad, if
Limited and Uncertain if MAN mode.
The CHANNEL value is used to select the measurement value. Configure the
CHANNEL parameter before configuring the XD_SCALE parameter.
