A supervisory node may poll the AlarmLog output for a short alarm history.
The last five alarm reports sent via nvoAlarm are reported via AlarmLog.
When ALARM_NOTIFY_DISABLED is entered into the log, further alarms
or return to normals are not entered into the log, until alarm reporting is
again enabled. If Alarm is bound and not being acknowledged, the last
alarm report entered into AlarmLog is the one that was not
acknowledged.See Alarm and AlarmStatus for related subjects.type [n]
specifies the alarm that was issued via Alarm. See Alarm for the alarm
types used in AlarmLog. The newest alarm is reported in type[0] and the
oldest is reported in type[4]. When a new entry is made to the log, the
oldest entry is lost.

UPDATE_ALL_FIELDS FieldNo: nvoData1 and nvoCtlDataG1 are output network variables
indicating the node status. The information contained in these network
variables are typically used to display the node status on an operator
terminal, used in a trend log, or used in a control process. The information
contained in nvoCtlDataG1 and nvoData1 are identical. nvoCtlDataG1 uses
the SGPUC mechanism to update the status or values. The fields in
nvoData are updated when network variables are polled by the receiver.
Then every six seconds the difference between the field in nvoData and
nvoCtlDataG is calculated. If the difference is significant the field is updated
according to the SGPUC mechanism. FieldNo indicates which other data
field in the SGPUC network variable has changed since the last time it was
sent on the network according to the SGPUC mechanism. If FieldNo is
UPDATE_ALL_FIELDS, then all fields have been updated. If FieldNo is
UPDATE_NO_FIELDS, then no fields have been updated recently.
