Anybody invoved in Plant Engineering?
I have been involved with a lot of projects with fresh air in factories (primarily). Getting smoke out, fresh air in, and having a slight positive pressure.
PLC's seem a natural for this, 'specially with remote I/O.
First, anybody familiar with a pressure switch to maintain slight positive pressure, so the doors aren't ajar, or slamming shut?
Second, anybody doing this now? Since this would require several intake fans on a large facility, do you turn some off, or have one or more of the larger ones on a VFD system?
With public smoking laws, I have also considered a smaller version of this for bars and restaurants. Though, only one or two exhausr fans would be needed. Again, some sort of air pressure sensor would be handy to have.
Any thoughts?

Feel free to submit twenty or thirty rungs of logic by ten minutes from now, and include some free RSLogix or Cimplicity, or AutoCAD E2006, and a stoplight program.
