Idx Parameter Description / Range / Selections / Note
 BLOCK_OBJ
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
 ST_REV
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.
 TAG_DESC The user description of the intended application of the block
 STRATEGY The strategy field can be used to identify grouping of blocks. This data is not checked or 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
TARGET AUTO / MAN / OOS The selectable modes by the operator.
ACTUAL The mode the block is currently in.
PERMITTED AUTO / MAN / OOS Allowed modes that the target may take on
NORMAL AUTO The common mode for the Actual.
 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 The process variable used in block execution, expressed in XD_SCALE Unit Code
 OUT
The block output value calculated as
a result of the block execution,
expressed in XD_SCALE unit code
Writeable only if MODE_BLK.ACTUAL = MAN
 SIMULATE Allow to simulate Value and Status that should be received from the PRTB.
 XD_SCALE Input Scale All the values are associated with the channel input value
 OUT_SCALE Output scale All the values are associated with the OUT
 GRANT_DENY
 IO_OPTS
Option which the user can select to alter Input and Output block processing

Low Cut Off Enable/Disable the LOW_CUT Off effect in the AI calculation
 Unit conversion
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
 STATUS_OPTS
Options which the user can select for the block processing of status. The available selections are:
 Propagate Fault Forward
Enable/Disable the propagation of the Status byte from the PRTB in input at the AI to
its Output

Uncertain if Limited

BAD if Limited

Uncertain if MAN Mode
 CHANNEL

Uninitialized ** Doesn’t allow at the AI to move out from OOS
