Parameter List
Table 7: Pressure Transducer block parameters
Parameter Description
ST_REV The revision level of the static data associated with the function block.
TAG_DESC The user description of the application of the block.
STRATEGY Used to identify grouping of blocks.
ALERT_KEY The identification number of the plant unit.
MODE_BLK The actual, target, permitted, and normal modes of the block.
BLOCK_ERR 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.
UPDATE_EVT This alert is generated by any change to the static data.
BLOCK_ALM The BLOCK_ALM is used for all configuration, hardware, and 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 sets the Active status
in the Status attribute. After 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.
TRANSDUCER_DIRCTORY A directory that specifies the number and starting indices of the
transducers in the transducer block.
TRANSDUCER_TYPE Identifies the transducer that follows.
COLLECTION_ DIRECTORY A directory that specifies the number, starting indices, and DD Item IDs of
the data collections in each transducer block.
PRIMARY_VALUE The measured value and status available to the function block.
PRIMARY_VALUE_TYPE The type of measurement represented by the primary value.
PRIMARY_VALUE_RANGE The high and low range limit values, the engineering units code, and the
number of digits to the right of the decimal point to be used to display the
final value.
CAL_POINT_HI The highest calibrated value.
CAL_POINT_LO The lowest calibrated value.
CAL_MIN_SPAN The minimum calibration span value allowed. This minimum span
information is necessary to ensure that when calibration is done, the two
calibrated points are not too close together.
CAL_UNIT The Device Description engineering units code index for the calibration
values.
CAL ACTION Used by the calibration methods to initiate a calibration on a device.
XD_ERROR Provides additional error codes related to transducer blocks.
