Unacknowledged R/W A discrete enumeration which is set to "Unacknowledged"
when an alarm occurs, and set to "Acknowledged" by a write
from a human interface device or other entity which can
acknowledge that the alarm/event has been noticed.
Uninitialized
Setting:
Uninitialized / Acknowledged / Unacknowledged
Alarm State R A discrete enumeration which gives an indication of whether
the alert is active and whether it has been reported.
Uninitialized
Setting:
• Uninitialized
• Clear - reported: Alarm not active and reported
• Clear - not reported: Alarm not active and not reported
• Active - reported: Alarm active and reported
• Active - not reported: Alarm active and not reported
Time Stamp R The time when evaluation of the block was started and a
change in alarm/event state was detected that is unreported.
The time stamp value will be maintained constant until alert
confirmation has been received - even if another change of
state occurs.
Uninitialized
Setting:
MM / DD / YY (Month / Day / Year)
HH:MM:SS (Hour:Minute:Second)
Subcode R An enumeration specifying the cause of the alert to be
reported.
Other
Setting:
Settings see above parameter "BLOCK_ALM", subelement
"Subcode".
Value R The value of the associated parameter at the time the alert
was detected.
