Configuration hints
The minimum configuration for having the AR working and/or moving out from the OOS needs at least the following settings:
• Set ARITH_TYPE with a valid value. It must be different by 0 and in the range 1 – 9
• If the selected ARITH_TYPE is in the range between 1-5 (limited functions), the output limits COMP_HI_LIM > COMP_LO_LIM
• The BAL_TIME must be greater than the Block Execution Time
• When the ARITH_TYPE = 6 (Average) in case of no inputs available the output will be set to NaN (Not a Number)
• Set the GAIN with value different by 0

Description / Range / Selections / Note
In the Block Object data structure, there are different items describing the block characteristics. Execution period,
Number of parameters in the block, the DD Revision, Profile Revision, View Objects characteristics and so on
The revision level of the Static data associated with the Function Block. The revision level is incremented each time a static
parameter value (S – under Storage) in the block is changed.
The user description of the intended application of the block
The strategy field can be 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, etc.
AUTO / MAN / OOS
AUTO / MAN / OOS
AUTO
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, expressed in PV_SCALE unit Code
The block output value calculated as a result of
the block execution, expressed in OUT_SCALE
unit
expressed in OUT_SCALE unit
The high and low scale values, engineering units code, and number of digits to the right of the decimal point to be used in
displaying the PV parameter and parameters which have the same scaling as PV.
The high and low scale values, engineering units code, and number of digits to the right of the decimal point to be used in
displaying the scaling for the output. It has no effect on the block
Options the user may select to alter the calculation done in a control loop

The Primary Input Value for the block coming from another block. Expressed in PV_SCALE Unit
Input for the low range transmitter, in a range extension application. Expressed in PV_SCALE Unit
The Primary Input Value for the block coming from another block. Expressed in PV_SCALE Unit
The Primary Input Value for the block coming from another block. Expressed in PV_SCALE Unit
The Primary Input Value for the block coming from another block. Expressed in PV_SCALE Unit
Constant Value above which the range extension has switched to the high range transmitter Expressed in PV_SCALE Unit
Constant Value below which the range extension has switched to the low range transmitter Expressed in PV_SCALE Unit.
The selectable modes by the operator.
The mode the block is currently in.
Allowed modes that the target may take on
The common mode for the Actual.
Writeable only if MODE_BLK.ACTUAL = MAN
Displays what would be the OUT value and status if the mode was Auto or
lower.
