Summary0001419: Monitored Item Queue handling - overflow bit
Description

5.12.1.5 Queue parameters defines:
If a Notification is discarded for a DataValue, the Overflow bit in the InfoBits portion of the DataValue statusCode is set.

This does not clearly define in which DataValue in the queue the flag is set.

Randy proposed:

DiscardOldest = true
-> The oldest value gets deleted from the queue and the next value in the queue gets the flag set.
DiscardOldest = false
-> The new value gets discarded. After sending the queue content to the client in a Publish Response, the next value put into the empty queue gets the flag set.

TagsNo tags attached.

Added clarification to 5.12.1.5
If DiscardOldest is True, the oldest value gets deleted from the queue and the next value in the queue gets the flag set. if DiscardOldest is False, the new value gets discarded. After sending the queue content to the client in a Publish Response, the next value put into the empty queue gets the flag set.

Change is part of the draft version "OPC UA Part 4 - Services Draft 1.02.02 Body.doc"
