Alex,

I am one of the ( I suspect growing ) band of users with WPs that
Foxboro tells us will be not repairable in 18 months.

The prospect of purchasing new Sun boxes with large prices for
licences/software etc. poses problems with  shrinking CAPEX funds.

Could I urge Foxboro to expedite the release of UNIX based replacements
before we are forced to accept options that may be difficult to fund.

Re: Linux based HMIs, Remote displays using VNC.

So the issue is price more than anything? The use of Linux and VNC
implies
that.

What's the right price point for an HMI?

Why?  We want more displays, and buying Foxboro WPs is rather
expensive.
And while the IT departments don't seem to mind, engineering doesn't =
have
the time to maintain MS Windows based machines.

How?  Install Linux (Debian) on old PC that are 'too slow' for current
MS Windows OS, that the IT department gives away.  We also display
DMs using VNC with a Linux box running a VNC server that 'displays'
the DMs.

5 dedicated

couple dozen desktop PCs or thin clients using VNC.

Linux based HMIs, Remote displays using VNC.
