Thanks
Yes, actually there are no plans for expansion, now we only want to upgrade
the CP module.
Really the main problem is that the change all FBIs to FBI10Es will
represent a process shutdown...
i think that i can change the CP40 and install one FBI10E pair, and under
it, the existent (old) Fieldbus
network. why not? does somebody have made this?

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).
