UserTokenPolicy

I’m using Ignition 7.6 with Kepware 6.6.
This is to allow a legacy application to communicate with AB PLCs v21 and higher.
The Kepware itself is all set and communicates with both a AB5500 PLC and an AB5069 PLC.
When I create the OPC-UA server connection I get this error;
’ no acceptable UserTokenPolicy present on selected endpoint’

This means you’re either connecting without a username and password but KSE requires one, or you’re connecting with a username and password but KSE is not configured to accept that.

It’s more likely the former, and you need to configure a username and password.
