Parameter List
Table 23: Arithmetic block parameters
Parameter Description
ST_REV The revision level of the static data associated with the function block.
The revision value increments each time a static parameter value in the
block is changed.
TAG_DESC The user description of the application of the block.
STRATEGY Used to identify grouping of blocks. This data is not checked of
processed by the block.
ALERT_KEY The identification number of the plant unit. This information may be used
in the host for sorting alarms, etc.
MODE_BLK The actual, target, permitted, ad 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
Normal: Most common mode for target.
BLOCK_ERR 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.
PV It calculates the proportions of IN and IN_LO to for PV.
OUT The analog output value and status.
PRE_OUT Displays what would be the OUT value if the mode is AUTO or lower.
PV_SCALE The high and low scale values, the engineering units’ code, and the
number of digits to the right of the decimal point associated with the PV.
OUT_RANGE The high and low scale values, engineering units code, and number of
digits to the tight of the decimal point associated with OUT.
GRANT_DENY Options for controlling access of host computers and local control panels
to operating, tuning, and alarm parameters of the block. (Not used by
the device)
INPUT_OPTIONS Option bit string for handling the status of the auxiliary inputs.
IN The block input value and status.
IN_LO Input of the low range Remote Indicator, in a range extension
application.
IN_1 The first block input value and status.
IN_2 The second block input value and status.
IN_3 The third block input value and status.
RANGE_HI Constant value above which the range extension has switch to the high
range Remote Indicator.
RANGE_LO Constant value below which the range extension has switch to the high
range Remote Indicator.
