I'm trying to download a program to a ControlLogix 5571 from our remote server but cannot see the link in RSWho. I had originally programmed the PLC from my computer locally but now I need to connect it to the server. I've set the IP address and can browse to the 1756-ENBT/A card through the web browser of our remote server. However, the server is running RSLinx Enterprise instead of RSLinx classic which I am more familiar with. When I try manually adding the Ethernet card to the list under "Communication Setup" the entry disappears after a new browse is started. Apologies for any incorrect terminology here as this is my first time trying to connect to a remote network PLC.
