Update State R A discrete enumeration which gives an indication of whether
the alert has been reported.
Uninitialized
Setting:
Uninitialized / Reported / 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)
Static Revision R The static revision of the block whose static parameter was
changed and is being reported. It is possible for the present
value of static revision to be greater than this because static
can be changed at any time.
0
Setting:
0…65535
Relative Index R The OD index of the static parameter whose change caused
this alert, minus the FB starting index. If the update event was
caused by a write to multiple parameters at the same time,
then this attribute will be zero.
0
Setting:
0…65535
WRITE_ALM WRITE_ALM WRITE_ALM WRITE_ALM
Write Alarm Write Alarm Write Alarm Write Alarm
Mix This alert is generated if the write lock parameter is cleared. -
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 / Clear - not reported / Active -
reported / Active - 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:
Other / Block Configuration / Link Configuration / Simulation
Active / Local Override / Device Fault State / Device
Maintenance / Input Failure / Output Failure / Memory
Failure / Lost Static Data / Lost NV Data / Readback Check /
Maintenance Needed / Power Up / Out Of Service
Discrete Value R The value of the associated parameter at the time the alert
was detected.
State 0
Setting:
Discrete State 0...16
