Table C-3: Definitions of Analog Input Function Block System Parameters
Index Number Parameter Units Description
01 ST_REV 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.
02 TAG_DESC None The user description of the intended application of the block.
03 STRATEGY None The strategy field can be used to identify grouping of blocks. This
data is not checked or processed by the block.
04 ALERT_KEY None The identification number of the plant unit. This information may
be used in the host for sorting alarms, etc.
05 MODE_BLK None 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
06 BLOCK_ERR None 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.
07 PV EU of
XD_SCALE The process variable used in block execution.
08 OUT EU of
OUT_SCALE The block output value and status.
09 SIMULATE None A group of data that contains the current transducer value and
status, the simulated transducer value and status, and the enable/
disable bit.
10 XD_SCALE 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.
11 OUT_SCALE None The high and low scale values, engineering units code, and number
of digits to the right of the decimal point associated with OUT.
12 GRANT_DENY None Options for controlling access of host computers and local control
panels to operating, tuning, and alarm parameters of the block. Not
used by device.
13 IO_OPTS None Allows the selection of input/output options used to alter the PV.
Low cutoff enabled is the only selectable option.
14 STATUS_OPTS None Allows you to select option for status handling and processing.
15 CHANNEL None The CHANNEL value is used to select the measurement value.
You must configure the CHANNEL parameter before you can
configure the XD_SCALE parameter.
16 L_TYPE None Linearization type. Determines whether the field value is used
directly (Direct) or is converted linearly (Indirect).
17 LOW_CUT % If percentage value of transducer input fails below this, PV = 0.
18 PV_FTIME Seconds The time constant of the first-order PV filter. It is the time required
for a 63 percent change in the IN value.
