At General Mills, we have started to lean toward using the new Wyse
5150SE terminal as a replacement for HP/NCD X terminals. It is a Linux
based device that is server agnostic; it supports X and Windows terminal
services (RDP/ICA). It needs to be mounted in an industrial just like a
PC or X terminal. It's retail price is approximately $400.
I would recommend a non-Windows based, thin client device (i.e. no
moving parts) in the "field." I would avoid duplication of display
engineering in a 2nd tool at all costs.

Just throwing out some ideas; I haven't personally tried any of this.

"Industrial" environmentally-hardened PC with Ethernet running some=20
Windows variant and Exceed/GoGlobal/VNC, or custom OS with X server, and
remote DM/FV from an AW/WP. These can be had with solid-state flash
disks=20
(no moving parts), panel-mount form factors, and NEMA 4/7 enclosures. A
special I/A environment could be set up to limit what the field

Panelview or something similar connected via FBM224/FDSI and Modbus.
The=20
Panelview would have to be capable of acting as a slave (polled device)=20
unless the FDSI supports being a Modbus slave itself (I don't believe
the=20
FBM224 does).
Other variations: OPC connectivity, for example, or using some

KVM extenders to put only the monitor and any input devices in the field
with the CPU (either a WP or a non-I/A PC) residing in the rack room.

Subject: [foxboro] replacing field Op panels
I have a need to remove a number of operator hardwired field panels. I=20
want
to replace them with a "display" panel. All I/O is wired to the I/A.
If=20
it
was a PLC I would install a panelview, anyone got any ideas? Brian Long
