plant SCADA as OPC UA Server

M Noman Danish ,

It looks like that I/O servers on the SCADA side are not running in the encrypted mode. You should run your SCADA server in the service mode for the encryption. If you run the SCADA server in the desktop mode, the certificate private key may not be accessible in some environment for the security reason. To troubleshoot

• Use "Page Table TRAN" in the kernel window of IO processes to confirm if they are in TLS mode.
• Check the IO server trace logs to see if there is any error somethin like "the private key is not accessible".
• Check tracelog.ConnectivityServer.dat in .\Logs folder on Connectivity Server machine

Hope the info here is helpful

Regards,

Jacky

Hi Jacky,

Thanks for your feedback. I just check the following.

Your runtime is not in the encrypted mode. The Security Info in the screenshot as shown below in indicates that my system is running in the encrypted mode. 

Please try the following

• In Encryption tab on Configurator, you need to tick "Enable Encryption"
• In Computer Setup tab on Configurator, select "Run Runtime Manager as Service"
• Also [Lan]TCPIP = 1 should be used in Setup Wizard
• Restart Runtime Manager server from Services window

Note the kernel window is not accessible in the service mode. But I think you should be able to browse the tag name space in your OPC UA client - dataFEED once your project is running in the service mode.

Hi Jacky,

I fallowed  the same steps but showing the same not browsing the tags.

M Noman Danish can you raise a ticket with support? 

Hi Antonio
I raised the ticket but unfortunately i don't have  CF ID or Site ID this time

Hi Jacky,

I followed the same step yout intructions, the result is working tag still browsed dan tag quality is good, then yesterday i try again to connect opc ua on aveva plan scada 2023 to ua client then result is same, but quality of tag is bad. What should I do to get the tag quality back to good quality?

Thanks

Sorry for the delayed response as I wasn't notified.

If you are still able to browse tags, it means the OPC UA server is connected to its I/O servers. The bad quality could be caused by I/O devices' offline, the tag value is out of range, and etc.  Check this tag on the SCADA side.
