Experimental Physics and Industrial Control System
|
The DZero Experiment at Fermilab has a HV record that includes a
state machine. Fritz Bartlett, the developer of our HV record, has
just become a "Guest Scientist Retiree" so he is still available for
consultation. We have a tutorial on our HV system at -
http://www-d0online.fnal.gov/www/groups/ctl/tutorials/high-voltage-
tutorial.pdf.
I can make the software available for those who are interested.

I strongly agree.
Creating templates for different power supply types are probably a
good way to go in most cases.
We even broke up our power supply templates into smaller units,
most of which are only consisting of a single record. (Templates
for "status word", "status bit", "command word", "command bit", ...)
The only exception - maybe - being a case where you have a large
number of very similar, very complex power supplies that need a
complex state machine to be operated. The only example that I know
of: high voltage power supplies in large detectors.
Even in such a case I would consider putting only the complex state
machine into a separate custom (or generic subroutine) record.
Good luck!

I would also welcome any advice or cautions you have, based on

Hi Susanna,
I had a similar idea 8 years ago for some in-house developed power
supply at PSI.
Luckily I got some advice not to do it that way (Thanks Bob!).
If you use one record per power supply, your application will
suffer from a lack of expandability, flexibility and usability.
