We can pull X-windows from any of our I/A workstations, so we haven't tried
anything special beyond that to display live alarm messages on a PC.  But we are
dumping the alarms to a text file, manipulating it with awk scripts, and
archiving the resulting reports.  We do this automatically each day, running it
using cron.  We produce various alarm reports and put them on the network so
they can be analyzed by any production folks with network access.

This is a low-tech approach, but it works and requires no new hardware or
software, just some fairly basic awk scripting.

For systems with legacy historians like ours, the data is in the file
/usr/hstorian/almhist.  The format of this file is funky and does not work with
commands like cat, pr or grep.  Foxboro has written a script that will dump this
file to a usable ASCII file for you.  Then you take it from there using standard
Unix text manipulation tools.

See the Foxboro Helpful Hint #714 for the script.  We haven't used the AIM*
historian package yet, so I don't know how you'd go about doing this on an AIM*
system.
