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_1 RW R DS-65 5 N
The block output 1 value and Status calculated as a
result of the block execution,
Writeable only if MODE_BLK.ACTUAL = MAN
8 OUT_2 RW R DS-65 5 N
The block output 2 value and Status calculated
as a result of the block execution,
9 X_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 variables corresponding to the x-axis for display. It has no effect on the block
10 Y_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 variables corresponding to the y-axis for display. It has no effect on the block.
11 GRANT_DENY RW R DS-70 2 S
12 IN_1 RW R DS-65 5 N Input 1 Value and Status
13 IN_2 RW R DS-65 5 N Input 2 Value and Status
14 SWAP_2 RW S U8 1 S
Changes the algorithm in such a way that IN_2 corresponds to “y” and OUT_2 to “x”.

15 CURVE_X RW A FLT 84 S Curve input points. The xi points of the curve are defined by an array of 21 points
16 CURVE_Y RW A FLT 84 S Curve output points. The yi points of the curve are defined by an array of 21 points
17 UPDATE_EVT R R DS-73 14 D This alert is generated by any change to the static data
18 BLOCK_ALM RW R DS-72 13 D
The block alarm is used for all configuration, hardware, connection failure or system problems in the block. The cause of the
alert is entered in the subcode field. The first alert to become active will set the Active Status in the status parameter. As soon
as the Unreported status is cleared by the alert reporting task, another block alert may be reported without clearing the Active
Status, if the subcode has changed.
