OPCUA and extension object tag

I should to communicate with a Beckhoff PLC via OPC UA
also I need read some ‘extension objects’ exposed from OPC UA. Ignition support this complex data?

In attachment few pictures of OPC UA Expert Client where you can see the data that I need read


Maybe is there a syntax where I can read single elements of the extension objects?

Thank you very much
Best regards


It’s not possible to read structures in the current version of the OPC UA module.

We have ongoing work to support this but it won’t be publicly available until Ignition 8.

Hi Kevin

Thank you very much


Hi Kevin.
Is there an update of the status on the extension object support development via OPC-UA in the OPC UA module of ignition?

I really need this feature

Regards Niels

If you’re willing to use a transitionary beta module (referred to as “OPC UA Next” around the forums) I can get you a copy of it.

That would be perfect. Please provide a copy for me.

While we are at it. I see some discussion on OPC-UA method calls. Is that also included in the current OPC UA Next development or would I need to wait for the version 8 release?
