Hello, I have a machine which sends data out via a proprietary communications protocol. It is essentially XML messages over TCP/IP sockets.
I need an OPC UA server to read these XML messages so that other OPC clients can extract real time data. I don't think KEPServerEX can help in this scenario.
What's the best way to do this? I prefer COTS product over SDK.
Thanks in advance.

Since you have a custom XML schema you will need to write code.
You should look for an SDK in Java or .NET because they have advanced XML parsing capabilities.

Thanks Randy,
I will look into an SDK like Softing dataFEED.
Can Ignition WebDev with Python resource do the trick?

WebDev could work. You could read and process the XML file and create/update/delete the necessary tags from Python.
You have to take into account that at the moment the Ignition OPC-UA module does not support status codes other than Good and Bad. There is no full OPC-UA support.
