BLOCK
Table C-4. LCD Transducer Block Parameters and Descriptions
Parameter 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.
