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 XD_SCALE Unit Code
The block output value calculated as
a result of the block execution,
expressed in XD_SCALE unit code
Allow to simulate Value and Status that should be received from the PRTB.

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
All the values are associated with the channel input value
All the values are associated with the OUT
Enable/Disable the LOW_CUT Off effect in the AI calculation
Enable/Disable the automatic Unit conversion of the variables in input at the AI from
the PRTB when their unit is different by the XD_SCALE.Unit
Enable/Disable the propagation of the Status byte from the PRTB in input at the AI to
its Output
** Doesn't allow at the AI to move out from OOS
