Block mapping
Idx Parameter Data Type Size Storage Description / Range / Selections / Note
0 BLOCK_OBJ mix R Mix 62
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
1 ST_REV R S U16 2 N
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.
2 TAG_DESC RW S O_STR 32 S The user description of the intended application of the block
3 STRATEGY RW S U16 2 S The strategy field can be used to identify grouping of blocks. This data is not checked or processed by the block.
4 ALERT_KEY RW S U8 1 S The identification number of the plant unit. This information may be used in the host for sorting alarms, etc.
5 MODE_BLK
TARGET RW
R DS-69 4
S AUTO / MAN / OOS The selectable modes by the operator.
ACTUAL R D The mode the block is currently in.
PERMITTED RW S AUTO / MAN / OOS Allowed modes that the target may take on
NORMAL RW S AUTO The common mode for the Actual.
6 BLOCK_ERR R S B_STR 2 D
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.
7 PV R R DS-65 5 D The process variable used in block execution, expressed in XD_SCALE Unit Code
8 OUT RW R DS-65 5 N
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
9 SIMULATE RW R DS-82 11 D Allow to simulate Value and Status that should be received from the PRTB.
10 XD_SCALE RW R DS-68 11 S Input Scale All the values are associated with the channel input value
11 OUT_SCALE RW R DS-68 11 S Output scale All the values are associated with the OUT
12 GRANT_DENY RW R DS-70 2 S
13 IO_OPTS RW S B_STR 2 S
Option which the user can select to alter Input and Output block processing
Bit 10 Low Cut Off Enable/Disable the LOW_CUT Off effect in the AI calculation
Bit 12 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
14 STATUS_OPTS RW S B_STR 2 S
Options which the user can select for the block processing of status. The available selections are:
Bit 3 Propagate Fault Forward Enable/Disable the propagation of the Status byte from the PRTB in input at the AI to its Output
Bit 6
Uncertain if Limited
Bit 7
BAD if Limited
Bit 8
Uncertain if MAN Mode
15 CHANNEL RW S U16 2 S
0 Uninitialized ** Doesn’t allow at the AI to move out from OOS
1 Pressure Process Value P-dP
2 Sensor temperature ST
3 Static Pressure SP
4 Scaled Process Value Lin PV
