Hi Vijay,
Our review of the Notification message indicates that the tags are read correctly. Can you now try this:
1. On the OPC Agent Settings tab set Browsing Mode (Da 2.05a) to Relative Path
2. On the OPC Agent Instance Query Ports tab, select Cache Mode = Cache
3. Set PCo Log Mode to Verbose and delete the log
4. Start the Agent Instance
5. Capture the simulation Notification message.
6. Execute the MII PCoQuery to read the tags.
7. Export the PCo Log, then set Log mode to Warning.
Post the simulation message and the Log export to this thread.
Regards, Steve
