node IOpcNode

The IOpcNode instance acting as the notifier.

Exceptions

ArgumentNullException

The context or node is null reference (Nothing in Visual Basic).

Remarks

If the node is the first notifier being added to the collection of notifiers the EventNotifier attribute of this OpcObjectNode is set to 'SubscribeToEvents'.
