Summary0006774: Sequence Number handling when publisher went out of service and came back online (Part 14)
Description

As described in the issue below:
https://mantis.opcfoundation.org/view.php?id=4371

The Sequence number shall be reset if there is no new message received for time period == 2 * keep alive time.

But this is documented under "Table 94 – Values for different sequence number sizes, recorded it" for UADP message mapping. But it is not mentioned in similar line for JSON message mapping.

Shall I consider the same is true for JSON message mapping as well?

TagsNo tags attached.

OPC 10000-14 - UA Specification Part 14 - PubSub 1.05.0 Draft33.docx

Added the following text to the description of SequenceNumber in Table 116 – JSON DataSetMessage definition:
Subscribers shall discard the records they keep for sequence numbers if they do not receive messages with the expected SequenceNumber for two times the keep alive time to deal with Publishers that are out of service and were not able to continue from the last used SequenceNumber.
