Weihenstephan protocol and Ignition

Ignition
1

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?

Hi Kevin,

Please find captures attached.

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
