Re: [foxboro] replacing field Op panels

I have several hardened PC's running Exceed or GoGlobal.  I believe 
GoGlobal has been withdrawn from sale so the only official Invensys choice 
is Exceed.  The last migration project we had involved a local control 
panel with 20 or 30 pushbuttons, pilot lights and 10 analog panel meters. 
We trashed the panel and replaced it with an X-terminal.  It saved a lot 
of money by avoiding the purchase of a bunch of migration I/O modules.

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.

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?
