Ditto here too but with CP30s. In our case we believe the issue was
with differing attenuation levels between buss's due to differing
lengths. Just a thought.

We experienced the exact same thing on CP60's that had both FBM200s
and
FBM100s. We were receiving constant PIO Bus faillure notices.
Foxboro
has a customer advisory or helpful hint that solved our problem, it
talks
about ground problems on the fieldbus for CP60's. This document was
close
to 40 pages long. I do not know the reference number but your Foxboro
field service man should be able to assist you. We had our Foxboro
representative down to fix the problem, but we were in an outage at
the
time. Since the grounding corrections have been made, we have not seen
the
problem recur. You would have to talk to Foxboro to see if the
corrections
could be made while running the unit.
