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 / OOS The selectable modes by the operator.
ACTUAL R D The mode the block is currently in.
PERMITTED RW S AUTO / OOS The allowed modes the operator can select as Target
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.
Bit 6 = Device Needs
Maintenance Soon
Refer to the section “Diagnostic, Block_err and Status Byte” from page 29
Bit 15 = Out of Service The MODE_BLK_ACTUAL = Out of Service.
7 UPDATE_EVT R R DS-73 14 D This alert is generated by any change to the static data
8 BLOCK_ALM RW R DS-72 13 D
The block alarm is used for all configuration, hardware, and connection failure or system problems in the block. The cause of the
alert is entered in the sub-code 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 sub-code has changed
9 TRANSDUCER_DIRECTORY R A U16 2 S Directory that specifies the number and starting indices of the transducers in the transducer block
10 TRANSDUCER_TYPE R S U16 2 S Identifies the transducer type.
11 XD_ERROR R S U8 1 D Transducer block error sub-code
12 COLLECTION_DIRECTORY R A U32 4 S Directory that specifies the number, starting indices, and the DD items IDs of the data collections in each transducer within a tb
13 PILD_COMMAND RW S U8 1 N
Activation /
deactivation of
the PILD
algorithms
0: IDLE default value
1: GO_OFF Switch OFF the PILD algorithm
2: TRAIN Start the training phase
3: STOP TRAINING Stop the training phase of the algorithm before its natural ending
14 PILD_STATUS R S U8 1 D
Status of the
PILD algorithm
0: OFF The algorithm is Inactive (Default value)
1: NORMAL The algorithm is Active
2: TRAINING The algorithm is in training phase
