Answer Posted / rajkumar
If you are using a DCS (Distributed Control System), there
should be a diagnostic utility that you can run (this is
usually part of the system software). If your sotware scan
is structured correctly i.e. all software is called in
cyclic scans and not free scans, the utility should be able
to tell you the loading of these scan cycles.
You should also be aware that you are doing this under FAT
conditions. This would imply that most of your IO are not
connected, which in turn would push up your scan times for
all the diagnostic alarms comming in.
