I have been adding many devices to the OPCUA server without issue, and have several hundred tags scanning continuously, including some historical polls. The issue I have now is that once I add a new device, it connects just fine and shows it as connected on the status screen, but then no data comes through. I don’t seem to get any error messages, yet the quick client cannot browse, and once I go into the designer I cannot see any tag values either. The following is the only information I get related these devices: Request Schedule SubscriptionItem Count 0 ScheduledRequest Count 0 RefreshRequest Cycle Request Throughput 1.0/sec Min Request Duration 2.0ms Max Request Duration 80.0ms Avg Request Duration 12.7ms Last Request Duration 4.0ms ---

Can you send your wrapper.log file(s) to [support@inductiveautomation.com](mailto:support@inductiveautomation.com)? On a default installation on Windows, they are at C:\Program Files\Inductive Automation\Ignition. ---

Best to send your logs to support and get a ticket started. They can verify if it’s the same problem or something else. ---

Yes, that’s the first thing they will ask for, along with what version of Ignition.
