i just realized that there is no import / export option for OPC-UA devices in 7.6. Is this by intention?
Sort of. I haven’t exactly figured out how to do import/export now that devices are just extension points. Once I do figure it out I want to implement a better version of device import/export than 7.5 had, because honestly, it was pretty poor.
So… it will come back eventually, but probably not in time for the 7.6 release.
