Stress monitor  
It is the amount of time the device has been used under stressful conditions. For example, say 
temperature of the device. The stress monitor is based on the temperature of the device. The Stress 
monitor is calculated in percentage. 
Stress monitor = Amount of time the device was under stressful conditions

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.
