Connecting InTouch 2014 to AB 1769-L33ER

Hi
We have a project that is based on an AB 1769-L33ER and I need to connect this to our InTouch 2014 Scada system.
We have installed the latest ABCIP IO Server and are ready to connect.
Can you directly address the PLC I/O like you would on a Mitsubishi or GEFanuc plc, or does everything you want to read need to be created into a Tag that is then read via InTouch.
It is a long time since I’ve connected to an AB PLC and that would have been an old SLC 5, so I’m sure things have changed.
I have had the PLC tags dumped, but these don’t look like I would have expected them to.
Any help appreciated.
