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.
