That's what I'm trying to find out.

If the control panel doesn't come with FRO/SSO dials, you can't add them as the controllers have no analogue inputs, and that is one feature I use quite a bit. Turning a dial is far better than continually pressing buttons.

The 990/1000 series controllers also have less IO available. 218MC has 47 of each, whereas going by my quick count of a 990/1000 series manual, they only have 21 In and 12 Out defined as user configurable. I suspect some of the dedicated In/Out can be used by editing the ladder, but I'm not wanting to spend that much time reading the manuals just yet.
Creating an In/Out spreadsheet will be one of my next jobs, as I think the current retrofit will need less than 12 outputs.
