Event
RfAlarmHandler(sender : object, args : RfAlarmArgs)
Exceptions
RfReaderApiException
Note
This event provides notifications about alarms whereas an alarm is considered not only as a
warning or error condition but also as a means of notification about changed system states.
Contrary to the TagEventNotifications event the Alarms event provides information even
without an explicit subscription (i.e. a call to SubscribeForAlarms in this case).
In order to distinguish errors from notifications the RfAlarmArgs may contain either an array
of RfAlarm objects or an array of RfInfoItem objects. Following is a list of the public members
of the alarm arguments.
