When upgrading to CP270's there is one advantage that we really
appreciate but is difficult to quantify. Check pointing went from about
20 minutes to about 2 minutes when we upgraded from CP60 to FCP270 for
the same configuration.

Subject: [foxboro] CP60 Sizing
Gentlemen,
I am proposing a migration to a Preferred platform of I/A. We
currently have I/A 7.1.1 with CP60 controllers. I would like to base
my proposal on two arguments:
1) Processor idle time is 30% and there are possible additions on the
way. Are there recommendations as to how little idle time is too
little?
2) We currently use A-B Stations to communicate with a series of
PLC-5/40E (Allen Bradley) and those are deprecated (no longer
supported by foxboro). I have found the lifecycle document that
supports this argument.
Are there any documents that support the first argument? Is it even a
valid one? Are there any other considerations I should make?
Cheers!
