I have done some playing with two codesys PLCs, and you have it right: with no connections listed on the Remote Adapter's Connections tab, it does not go to Running. Adding a valid connection gets it to running. Once in running, the generic service works.
The thing is, valid connections here are only special class 1 connections, you can't just choose any available service/class/instance/attribute. The only class 1 connections I know of for a Logix Processor are produced tags.
I couldn't find a document describing the correct format for these produced tags. I assume it would just be the symbolic path... But how much data does it need to send? If someone has a wireshark of a successful Produce Consume, you or I could dissect it and see what is needed.
