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_SCALE 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 OUT parameter and parameters which have the same scaling as OUT.
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 0 IFS if BAD IN
Bit 2 Use Uncertain as Good
11 SEL_1 RW R DS-65 5 N First input value to the selector
Expressed in OUT_SCALE Unit12 SEL_2 RW R DS-65 5 N Second input value to the selector
13 SEL_3 RW R DS-65 5 N Third input value to the selector
14 SEL_TYPE RW S U8 1 S
This parameter specifies the type of selector action 2

15 BKCAL_IN RW R DS-65 5 N
The analog input value from another block’s BKCAL_OUT output that is used to prevent reset windup and to initialize the
control loop. Expressed in OUT_SCALE Unit
16 OUT_HI_LIM RW S FLT 4 S
Acceptable value: OUT_SCALE +/- 10%
Expressed in OUT_SCALE Unit
Limits the maximum output value.
17 OUT_LO_LIM RW S FLT 4 S Limits the minimum output value.
18 BKCAL_SEL_1 R R DS-65 5 D
Control selector Value and Status associated with SEL_1 input which is provided to BKCAL_IN of the block connected to
SEL_1 in order to prevent reset windup. Expressed in OUT_SCALE Unit
19 BKCAL_SEL_2 R R DS-65 5 D
Control selector Value and Status associated with SEL_2 input which is provided to BKCAL_IN of the block connected to
SEL_2 in order to prevent reset windup. Expressed in OUT_SCALE Unit
20 BKCAL_SEL_3 R R DS-65 5 D
Control selector Value and Status associated with SEL_3 input which is provided to BKCAL_IN of the block connected to
SEL_3 in order to prevent reset windup. Expressed in OUT_SCALE Unit
21 UPDATE_EVT R R DS-73 14 D This alert is generated by any change to the static data
22 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 alert will set the Active Status in the status parameter. When 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
