Update Event Update Event Update Event Update Event
R This alert is generated by any change to the static data. -
Unacknowledged R 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. Time stamp records the time when parameter
was updated.
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
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.

Transducer Scale Transducer Scale Transducer Scale Transducer Scale
R/W The high and low scale values, engineering units code and
number of digits to the right of the decimal point used with the
value obtained from the transducer for a specified channel.
