Hi All,  
I have a filling machine that apparently has information available via the Weihenstaphan protocol. Has anyone used Ignition to communicate via this protocol before? I can connect to to OPC-UA server on this machine using UA-Expert, but when I try to connect with Ignition I get UaServiceFaultException: status=Bad\_ServiceUnsupported, message=The server does not support the requested service.

I think I will ask the filling machine company to update the machine to support OPC-UA with Ignition. But they have mentioned the Weihenstephan Protocol

OPC UA should be the way forward.

Can you get a Wireshark capture of Ignition vs UaExpert connecting?

Ok, yeah, you'll have to work with the vendor of this server. It looks like the server returns BadServiceUnsupported in response to a FindServersRequest.

You might be able to get connected if you use the "skip to advanced" part of the discovery wizard and put:

- Discovery URL: `opc.tcp://10.17.235.152:4850`
- Endpoint URL: `opc.tcp://K731-E5U:4850`
- Endpoint Host Override: `10.17.235.152`
- SecurityPolicy / SecurityMode: `None`
