One interesting thing is, that with at least two of the vendors you mentioned
(Emerson/Fisher-Rosemount and, at some point in the near future I believe,
Honeywell), their Windoze-based systems aren't just for small/medium size
applications. They claim scalability from a one-rack SCADA setup to
We second that emotion (I'll be 70 before I buy a '70 :-)
We are currently in a similar situation trying to integrate some devices via an
OPC server, and looking at the 3rd-party approach as well. I like the
super-integrator (CP60 with Ethernet comms) idea as well, although one of

Commercial products are bad things.
Nice Freudian slip ;-) Seriously, free ones are not bad, either: check out

We have had this problem as well. As Chad said, it exists because the dropping
resistor on Foxboro FBMs is 50 ohms, which does not give enough loop resistance
for the HART handheld to read the superimposed digital signal.
I do not believe Foxboro offers a 250-ohm dropping resistor option (I
I tried VNC awhile back on an AW51E. It worked pretty well, but I ran it in
daemon mode, and it had a tendency to die unexpectedly when no one was
connected. I plan to do more experimentation on it when I get some time.
As a side note, I frequently use the Solaris VNC client to take control of
When did this get announced? Is this the Integrator line? What about the
Allen-Bradley ones? What is Invensys' proposed replacement?
We don't have Modbus but have 3 A-B Integrator 30s. Some other plants at our
site do use MB Integrators though.

Yes, but it would be much cleaner if it were just part of the AO FBM's onboard
diagnostics. I would even settle for a single A/D for all output channels,
multiplexed between them on a 5 or 10 second cycle, if circuitry or PC board
space is an issue.
Thanks to all who responded.

The DNBI/DNBT, among other things, handles the switching between the redundant
nodebus segments. Your DNBI/DNBT actually connects to the AW/WP via an ethernet
card (the DNBI also uses a serial port, I presume for the switching and other
types of data; the DNBT does it all in-band over the
To answer Kevin Fitzgerrell's question, I am opening the loop at the FBM.
Neither the detail display nor system management shows anything awry. The
output is therefore not initialized and can be manipulated.
My experience agrees with what Rick Rys said. I was hoping that the FBM could

This is correct, except that it is used for all NetBIOS name resolution; i.e.,
NetBIOS layered over TCP/IP or IPX as well as the raw NetBEUI. It is used for
things like mapping drives to other NT boxes if you don't have a WINS server
(and depending on the NetBIOS node type of the machine, etc.,
Or, we could design the system in the first place to allow save-alls while the
configurator is running, and maybe prevent a save in the configurator to a
compound that is currently being saved. Or better yet, do away with all these
different database snapshots (save-alls, checkpoints, ICC
Just curious: Is FoxView that bad, or is it just a pain to migrate? I'm
relatively new to I/A. and find the legacy Display Builder a cumbersome tool to
build graphics in (although some of the guys in the plant who have done it more

I was trying to get up to speed on building DM graphics.
But while we're on this topic, why aren't the configurator documents on the CD?
Is the legacy DM/DBuilder being further enhanced, or is it frozen from a
Does anyone know if I/A analog input cards (FBM01/04 in my case) can be had with
250-ohm dropping resistors? My meter tells me the ones we have are 50-ohm, and
most HART handhelds we've used require 250-ohm loop resistance to function
properly.

You might try something like:
su - unprivileged_user_id -c netscape
This is not quite as good as chroot but at least keeps them from overwriting
files.
Of course the real fix is for Foxboro to modify their software so it doesn't
have to run as root.

Just out of curiousity, how would one do the FoxDoc updates for, say, a web
server running on an AW51
so one can have current local documentation accessible from all the stations?
From what I've seen, the
updater is a Windoze program. I could do the updates on a Windoze box and copy
them over,
Just out of curiousity, can't DM/FV lock the display file it is currently

No. The _source_ code is generally compatible, but binaries are not generally
compatible across platforms for any OS. You have to compile it on each
platform.
