See nvoAlarm.type A central node may poll this output variable for a short history of
alarms. It contains the last five alarms reported via nvoAlarm. At
the time a new nvoAlarm is issued, nvoAlarmLog is updated.
See nvoAlarm.type See above.
See nvoAlarm.type See above.
See nvoAlarm.type See above.
See nvoAlarm.type See above. nvoAlarmLog.alarm_type[4] is the oldest alarm.
This output variable is a polled output containing a list of all the
current errors detected by the node. A search for error conditions
in the node is made periodically. A central node may poll the
nvoAlarmStatus output for all of the current errors. nvoAlarmStatus
contains all the current detected errors even though they may be
suppressed for reporting by nvoAlarm.
See above.
