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
Value
R
The value of the associated parameter at the time the alert
was detected.
0
Setting:
0...255

to this I/O block. This information defines the transducer to be
used going to or from the physical world.
