Kevin, This is an interesting concept for Operator stations. I think it has been part of theoretical discussions on this site for quite a while but this is the first practical use, I think. Are you able to set up alarms by work station (client) area? Is your plant ready to approve wireless keyboards for alarm management? If the "former" concept had 50 workstations, how many servers will be available to serve displays and alarms to your 15 (future) client stations? Do you have an independent safety system (ISA 84) covering your processes, too? Or is your process such that a safety system is not required? Terry Doucet, Eng. Re: [foxboro] P92 Quad KVM Extension Shaun, My solution may not work for you, but I'll chime in here anyway. We're going another route for our workstation upgrades. I'm putting P91s in our cabinets (big cabinets!) and using IGEL 2110 LX thin clients at the operator stations. Thin clients have come a very long way since we struggled with the WYSE ones 4 or 5 years ago. I'm pretty pleased with these things, the following is me being enthusiastic, not a sales pitch or recommendation: These IGELs have two video outputs so I can run dual headed. The resolution runs up to 1920x1440 on the VGA and 1600x1200 on the DVI. Mine run Linux (the LX model) but they are also available with CE or XP embedded. There is a 4 headed version that might work for you in lieu of KVM extenders, but I've never tried to RDP a really big desktop with multiple monitors. I can use these to connect to ALL of my IA boxes - they will get RDP sessions from my P91s, and X windows from my Solaris 10 and 51 series boxes. I can connect to a different server on each head for redundancy, or I can extend a single desktop across both heads. I get an XDMCP session from a 51 series box and run it at 256 colors for DM on session or head and another XDMCP session from a Solaris 10 box with 65K colors for FoxView to do side by side evaluations as I migrate from DM to FoxView - makes it very easy for the operators to show me their concerns. Although I do have access to the shell, I haven't needed it, as the setup & configuration menues are excellent. For around US$250 I'm very pleased with these. They have an evaluation program, so if you want to try some you don't have to buy first. My overall plan is to have 2 P91s and a P82 in each major plant area, and run the 2 headed thin clients in the control rooms off of these, with each client connecting to two of the servers, one session on each head. I'll preserve a local head on each server for engineering or emergency operator access. This should let me go from about 50 workstations to 15 over the next few years, and actually improve reliability in most plant areas.
