Index

Description

ALERT_KEY

4

The identification number of the plant unit.

BLK_TAG_1

15

The tag of the block containing DP1.

BLK_TAG_2

21

The tag of the block containing DP2.

BLK_TAG_3

27

The tag of the block containing DP3.

BLK_TAG_4

33

The tag of the block containing DP4.

BLK_TYPE_1

14

The enumerated block type for DP1's block.

BLK_TYPE_2

20

The enumerated block type for DP2's block.

BLK_TYPE_3

26

The enumerated block type for DP3's block.

BLK_TYPE_4

32

The enumerated block type for DP4's block.

BLOCK_ALM

8

The BLOCK_ALM 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 attribute. 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.

BLOCK_ERR

6

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.

COLLECTION_DIRECTORY

12

A directory that specifies the number, starting indicies, and DD Item ID's of the data collections in

 

 

each transducer block.

CUSTOM_TAG_1

17

The block description that is displayed for DP1.

CUSTOM_TAG _2

23

The block description that is displayed for DP2.

CUSTOM_TAG _3

29

The block description that is displayed for DP3.

CUSTOM_TAG _4

35

The block description that is displayed for DP4.

CUSTOM_UNITS_1

19

This is the user entered units that are displayed when UNITS_TYPE_1=Custom.

CUSTOM_UNITS _2

25

This is the user entered units that are displayed when UNITS_TYPE_2=Custom.

CUSTOM_UNITS _3

31

This is the user entered units that are displayed when UNITS_TYPE_3=Custom.

CUSTOM_UNITS _4

37

This is the user entered units that are displayed when UNITS_TYPE_4=Custom.

DISPLAY_PARAM_SEL

13

This will determine which Display Parameters are active.

 

 

Bit 0 = DP1

 

 

Bit 1 = DP2

 

 

Bit 2 = DP3

 

 

Bit 3 = DP4

 

 

Bit 4 = Bar Graph enable

MODE_BLK

5

The actual, target, permitted, and normal modes of the block.

PARAM_INDEX_1

16

The relative index of DP1 within its block.

PARAM_INDEX_2

22

The relative index of DP2 within its block.

PARAM_INDEX_3

28

The relative index of DP3 within its block.

PARAM_INDEX_4

34

The relative index of DP4 within its block.

ST_REV

1

The revision level of the static data associated with the function block.

STRATEGY

3

The strategy field can be used to identify grouping of blocks.

TAG_DESC

2

The user description of the intended application of the block.

TRANSDUCER_DIRCTORY

9

A directory that specifies the number and starting indicies of the transducers in the transducer

 

 

block.

TRANSDUCER_TYPE

10

Identifies the transducer that follows.

UNITS_TYPE_1

18

This parameter determines where the units for the display parameter come from.

UNITS_TYPE_2

24

This parameter determines where the units for the display parameter come from.

UNITS_TYPE_3

30

This parameter determines where the units for the display parameter come from.

UNITS_TYPE_4

36

This parameter determines where the units for the display parameter come from.

UPDATE_EVT

7

This alert is generated by any change to the staic data.

XD_ERROR

11

Provides additional error codes related to transducer blocks.
