I have a project that will have an SLC 5/05, and an ethernet Panelview. There's a possibility for future upgrades (PC/another PLC/etc...) so I don't want just a direct dial into the serial port of the SLC. I was looking at getting a LAN modem to dial into the ethernet. I searched this site and came up with info on an ethernet LAN modem from 3COM, but on 3COM's site it says the 56k LAN modem is dicontinued. Is this still available? Or is my only option the pricey AB 9300-RADES?
