I think I need to connect the SI2 port on the S5 to a CP340 and use the 3964(R) protocol? If anybody has any examples of this it would be greatly appreciated

Once that is determined, let us know to see what can or needs to be done to link it to an S7.

Nevermind, answer in that case is Yes, a 6ES7340-1AH02-0AE0 card will be OK for the S7-300 comms, along with a TTY to RS232 Converter cable. Personally I think I'd rather upgrade the 95U to an S7 though and save myself the CP340 cost and engineering hassles associated with this link. Still, it'll have to work though as far as I'm concerned. As an option, have a look at Process Informatik's S5-LAN++, it may just be your get out of jail for (almost) free card.
