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 OUT RW R DS-65 5 N The block output value calculated as a result of the
block execution, expressed in OUT_SCALE unit
Writeable only if MODE_BLK.ACTUAL = MAN
8 OUT_RANGE RW R DS-68 11 S
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
9 GRANT_DENY RW R DS-70 2 S
10 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
11 IN_1 RW R DS-65 5 N Input 1 Value and Status
12 IN_2 RW R DS-65 5 N Input 2 Value and Status
13 IN_3 RW R DS-65 5 N Input 3 Value and Status
