Parameter List
Table 16: Diagnostic 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 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. 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.
EL_TEMP_DIAGNOSTIC Electronic Temperature Diagnostic parameters.
POWER_TRAC Power Up Track Data.
OP_VOLTAGE Operating Voltage.
TIME_IN_SERVICE
Summation of time in minutes that power has been applied to the
device since leaving the factory.
SERVICE_LIFE It is the elapsed Service life of device in percentage.
STRESS_MONITOR
It monitors various diagnostic parameters which are then input
into an algorithm to calculate an estimated percent of time that the
Remote Indicator has spent in stressful conditions.
