Hi ,

I am in the process of upgrading 3.16 version to 3.17 version. Need to migrate the existing WinncOA OPC UA server to 3.17 version.

While testing the new version, it was found that I could connect to the server, but not able to see the tags added in opcua dpgroup.

config file:

[opcuasrv]
disableSecurity = 1
enableAnonymous =1

Am I missing something? I have tested in both Windows and centos version.

Thanks,
Bala

Found the issue. Internal datapoint for OPCUA dpgroups changed in new version.
