Also look at the programming tools, we use mostly Schneider PLCs (although we do have most other flavours on site) and UnityPro to program them. The backend of UnityPro is XML driven and so you can use Unix "Make" and your favourite regular expression/string handling tools to build the whole PLC from a script. Very handy  for large I/O counts where you have a lot of similar code that becomes tedious to manage in the native click and point environment.

If you mange these scripts in CVS or similar it also becomes very easy to diff the scripts to see what might have changed between versions.

Yes, I'd very much like to get in contact with your local expert.

We're looking at the AB ControlLogix and CompactLogix (particularly the
Compact) as well.  Also looking at the Siemens S7-300 and Yokogawa FA-M3
product lines.

They all definitely have advantages and disadvantages.
The real plus for the AB is it's support of CIP, which puts interfacing with
EPICS fairly easy.

The Siemens - well - it's Siemens - you either love them, or you don't.

Yokogawa certainly has an interesting product with the FA, for which there
is an actual EPICS IOC that directly executes on the thing (although I'm
told it's kind of expensive - I haven't seen any pricing on it).

The GE however, seems to have the kind of power and high point count
integration we're needing.  None of the other PLCs have high channel count
analogs (GE has 64 channel 16 bit), or high count Digitals (GE and Yokogawa
both have 64 bit DI's and DO's).

Other problem is space.  Only the GE is going to easily fit 19" rack spaces
efficiently.

Gotta expand my spreadsheet for comparison quite a bit.
