Depends upon why you are upgrading to the CP60 ...
If you are upgrading to get better throughput or add more FBMs =
(including the 200 series), then you need to string coax and replace the =
FBIs with DCMs. You'll be able to use up to 120 FBMs because the DCMs =
store and forward Fieldbus messages (that's where you get the =
performance increase on the 10Mbps line).
If you just want the latest hardware and no plans for expansion, mount =
the DCMs near the CP60 and drive your existing twinax. You'll get no =
increase in performance out of the I/O (although you will have more =
block capacity and CPU throughput).
