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 / CAS / RCAS / ROUT / OOS The selectable modes by the operator.
ACTUAL R D The mode the block is currently in.
PERMITTED RW S AUTO/MAN/OOS/IMAN/CAS/RCAS/ROUT/LO Allowed modes that the target may take on
NORMAL RW S AUTO / CAS 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 PV_SCALE unit Code
8 SP R/W R DS-65 5 N
The analog Set Point value of this block,
expressed in PV_SCALE Unit Code
Acceptable value: PV_SCALE +/- 10%
9 OUT RW R DS-65 5 N The block output value calculated as a
result of the block execution, expressed in
OUT_SCALE unit code
Writeable only if MODE_BLK.ACTUAL = MAN
10 PV_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 PV parameter and parameters which have the same scaling as PV.
11 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.
12 GRANT_DENY RW R DS-70 2 S
13 CONTROL_OPTS RW S B_STR 2 S
Options the user may select to alter the calculation done in a control loop
Bit 0 Bypass Enable
Bit 1 SP-PV Track in Man
Bit 2 SP-PV Track in ROut
Bit 3 SP-PV Track in LO or IMan
Bit 4 SP Track retained target
Bit 5 Direct Acting
Bit 6 Track if Bad TRK_IN_D
Bit 7 Track Enable
Bit 8 Track in Manual
Bit 9 Use PV for BKCAL_OUT
Bit 12 Obey limits if CAS or RCAS
Bit 13 No out limits in Manual
