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 / CAS / RCAS / ROUT / OOS
AUTO/MAN/OOS/IMAN/CAS/RCAS/ROUT/LO
AUTO / CAS
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 analog Set Point value of this block,
expressed in PV_SCALE Unit Code
The block output value calculated as a result of
the block execution, expressed in OUT_SCALE
unit code
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 OUT parameter and parameters which have the same scaling as OUT.
Options the user may select to alter the calculation done in a control loop

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.
Acceptable value: PV_SCALE +/- 10%
Writeable only if MODE_BLK.ACTUAL = MAN
