Yep, Venturecom came out with Windows RTX running on Windows NT a long time ago. I think that same software package or company has been bought and sold now 2 or 3 times.
Here it is... http://www.intervalzero.com/ About two years ago I inquired about the price per copy of Windows RTX running under Windows XP and they wouldn't give me a price via email, a distributor contacted me a few days later. I never did get a price but you can bet it was more than a few hundred bucks. I have heard it is in the $1000 plus range per copy for low volume users. I used to work with some Siemens software that ran on Windows RTX and it was very stable. Chrysler has several transmission assembly lines that are run via PCs. The software is based on Siemens soft S7 PLC software engine. Siemens MMI software runs on the same PC and hooks in the virtual PLC so it all runs on the same box. The PLC scan/loop time is in the 1 millisecond range which is fast enough for general machine control. For I/O the standard interface used to be Profibus, but I think that the current versions also support Profinet which is more or less Profibus over Ethernet. The application your run on Windows RTX has to be programmed specifically for Windows RTX, you can't just load Windows RTX, load up Mach3 and have Mach3 run in real time. Part of what IntervalZero sells is the development environment support for the OS, so you can use it with the typical Windows programming tools from Microsoft.
