My turn.... I couldn't let David stand on his soapbox alone! In my humble opinion, Foxboro (and most of the other DCS manufacturers) has miserably failed to produce the marketed results of the Microsoft craze. Many, many years ago we were inundated with wonderful presentations showing us the future of IA's openness and interoperability we would receive if "only" we would move from UNIX to Windows. So far, the only thing that has come from this is the worries of virus attacks and a decent non-redundant OPC I/O Gateway. You can take your own chances by installing third party software on the your Windows boxes, but don't call TAC for support or they will tell you to take it off and call them back. Yes, if you are buying a new system and don't care about only working on one control database at a time, then the system is okay. But, the "as promised" system from many years ago is still many years away. I still think the 70 series is for small, one-node systems. At least that is the only way I would use it. I have replaced some of my WP51's with XP boxes, but they have other WP's nearby when we have to "work" on them. You can use Ghost to backup Windows boxes, but make sure you use the Enterprise version. This is not supported "officially" by Foxboro either, even though their service people use it. As far as reliability goes, if you install the Windows system and never add any questionable software, it seems to run pretty stable. But it's not a matter of IF it is going to need a reboot only a matter of WHEN. With UNIX, this was never a problem for me. But the point I/we are trying to make is that Foxboro has promised the sun and moon without delivering anything useful to existing large IA users.
