Hello community,

I am tusing vtscada light 12.55 and i am failing to connect to a my PLC via an OPC UA server.

Any help will be greatly appreciated

You'll need to explain your issue a bit more, failing to connect could occur for many reasons.

The OPC UA Client topic in the help file might help, see https://www.vtscada.com/help/Content/D_Tags/D_OPCUA_Tag.htm

Thanks for the reply Graham,

I don't have much information except that it a server with a user and passwrod to access it but i don't hav a certificate. The strange thing is it has worked on 2 other softwares i am currently using.

This is what my screen looks like it would have been beneficial if i was gettin some error notifications as to why I am not getting any readings in the diagnostics page.
