Remarks

A notification message fails to be received if the response delivering it cannot be processed, for example because a value of a data type in it cannot be decoded. The data changes and events of such a message do not reach the DataChangeReceived and EventReceived events.

A OpcNotificationFailedEventArgs instance is first passed to the NotificationFailed event of the Subscription the message belongs to. In case there no handler will set Handled to the value true, the instance is passed to the NotificationFailed event of the owner of the OpcSubscription. A message whose subscription is not known is passed to the NotificationFailed event only.
