There's a thread [here](https://forum.inductiveautomation.com/t/rtac-hosted-opc-ua-and-iec-61850-data-structures/71662) where people have all been connected and dealing with some other issues.

That was a few years ago and the OPC UA server feature had just been released, it's probably in a bit better shape now. I've also seen via support a few instances of people connected this way.
