Terry, I've discussed the idea before, but thin clients haven't been capable or versatile enough to implement this until fairly recently. I'm justifying this as a cost saving measure, but I'll also demonstrate improved reliability. In my two major plant areas I'll be sending all plant alarms to all three servers. In the other areas I'll have to do something different, but the V8.x alarm management system looks promising to send alarms to individual display managers. We're not ready for wireless keyboards I don't think. I'll run out cable from my servers to GCIOs and keep my current Annunciator keyboards for now. The current system has about 50 workstations. The new concept will have 15 servers - 2 windows P90 or P91 and a Solaris P82 in each of 5 major plant areas. I do not have safety systems.
