OPC Quick Client License Issue

[JM_12698707]

Hello everyone,

I’m seeking help with an issue I’m encountering with KEPServer. Our facility holds a KEPServer license for the Manufacturing Suite, Sixnet Ethernet, Advanced Tags, and Scanivalve modules. These licenses were originally linked to an older computer running Windows XP, likely with KEPWARE version 5.3 or 5.4. As part of a recent system upgrade and expansion, I transferred these licenses to a new machine running Windows 10 and KEPWARE version 6. The license transfer seemed to go smoothly without any issues.

However, I’ve noticed that the OPC Quick Client sessions work for a while and then time out, becoming unresponsive after that. Interestingly, I’m still able to read and write tags from our LabVIEW control programs and other process control software. This problem only started after transferring the licenses to the new system, as I didn’t experience this issue on the old machine. Has anyone here experienced something similar?

Please note, I am not using trial versions or free software; we have active and valid licenses.

I would be surprised if I need to purchase a separate license for OPC UA Quick Client sessions. Any suggestions or recommendations would be greatly appreciated.

Hi @Catalina 

Thank you for your response to my question. The issue I'm experiencing is documented in Article CS276365. Although I have tried the recommended solutions, such as reinstalling and downgrading the version, the problem persists. I have logged a case ID in myKepware portal but have not received any updates, even after setting the severity level to high and escalating the case. I hope I can find a solution here or through the logged case ID.

Thanks
