The OPC DA Server service uses %PIPC%\PI_OPCDA2\Data\SavedNamespace.xml to load the tags and does not update the cache until the service is stopped and started again. If any new tag is added to the PI Server, it is not picked by the OPC DA Server. The service should periodically update its cache from the PI Server after the initial start.15 votes
With PI OPC DA Server 2017, SDK aliasing is no longer supported. It would be nice to be able to not reconfigure the client's ItemIDs and use an alias after migrating a Data Archive.2 votes
As a PI OPC DA Server User, I would like to be able to create groups of tags (items) on the OPC Server, so that when I look for a specific tag in an OPC Client tool I don't have to search through the thousands of other tags that exist on my PI Server. This will make using the PI OPC DA Server more efficient and enjoyable.1 vote
