I've gone the hardened PC route and set up all WP's and AW's with second
Ethernet ports and extra DM licenses. The PC's connect via a switch, so
that we can easily move a PC to run off of another workstation when we wish
to back up the workstation. This has worked very well for us, and saved us
lots of $.

Subject: Re: [foxboro] replacing field Op panels
Just throwing out some ideas; I haven't personally tried any of this. Each
has its advantages and disadvantages
"Industrial" environmentally-hardened PC with Ethernet running some
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
(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 operator
could see/change.
Panelview or something similar connected via FBM224/FDSI and Modbus. The
Panelview would have to be capable of acting as a slave (polled device)
unless the FDSI supports being a Modbus slave itself (I don't believe the
FBM224 does).
Other variations: OPC connectivity, for example, or using some fiber-optic
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
want
to replace them with a "display" panel. All I/O is wired to the I/A. If
it
was a PLC I would install a panelview, anyone got any ideas?
