11*8 = 88 analog IO that should be enough. however if you are purchasing the plc new why not go for a CJ1 these are the latest and greatist with a lot of support for other things like ethernet, device net, and some other cool stuff like memory cards so that if your link goes down you could store the data on the card and then resume once the link comes back. They are not that much more expencive and have way better capabilitys. I dont belive that omron sells radios, however any RS232 radio should work.

11*4 maybe?

can you not get 8 analog in on the cqm and only 4/ op card. anyway If it were me I would go with CJ1 or CS1 and devicenet. then there are almost no limits......

4 analog points per card maximum on CQM1(H).
