It may sound prehistoric, but we're planning on hardwiring our critical
vlves and pumps to solve this checkpoint issue, most of our vlves are
fail to close, so the unexpected shutdown is not so much of a problem,
the unpredictable checkpointfile reboot is much more of a problem. We
need to be sure our critical equipment is in the desired default
position, by pushing a hardwired button, before the system starts up
again. We can then "unlock" the valves after the DCS settings are
checked and adjusted. Cost is relitavely small compared to disaster
recovery.....
We're also still considering any good, clean DCS suggestion.....

Subject: [foxboro] Troubles with the Checkpointfile
Hi,
We use different releases of IA Fox-Systems (6.2 - 8.1, Solaris, NT,
XP).
In my opinion, the checkpoint-file will be generated, updated after=20
CIO-Config changes, with the current CP-Image.
And after a reboot the checkpointfile will get loaded in the CP.
The problem is, we never know the state of the Checkpointfile. So, its=20
state can be like the state we had, months ago, when we
did some changes on the cio.
So if we get a power failure on the system, and all CP's reboot, an
"old"=20
checkpointfile get loaded and we get a state of the system we don't
want.
Motors, pumps, etc. starts, they weren't running before the failure, but
they were running during last checkpoint (Months ago).
I would like to get the system after reboot in a safe state. Best would
be=20
the default values of the cio-config. (Workfile)
Any ideas?
Regards Patric
