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.
