I have a logger I’m experimenting with / putting together that runs the open62541 client. I’d like to connect to the Ignition OPC-UA server so I can nab a couple tags from the PLC and log the data changes.

I want to do this external of the Ignition client. Is it possible to connect an external client to the OPC server?

If yes, how do I do so?

I saw some old threads on this subject that gave mixed signals. In order to avoid thread necromancy on an 8 year old question, I figured I would start a new topic.

Thanks!

Joe

EDIT: Of course I found the answer right after posting. Changing the listen address from localhost to the IP of the machine makes it work.

Good one. Automation community needs an affordable alternative for Kepserver, especially on Linux 🙂
