What’s the difference between the two LAN ports on my HMI/cMT?

The specifics will likely differ based on which device you’re specifically working with, but in general, LAN 1 is the port you’d use for a network connection that goes out to the internet, where LAN 2 is strictly for Local Access Networks.

In general, we recommend keeping to LAN 2 on your device, unless you have a good reason to need internet connectivity, such as sending E-mail notifications, or logging in to EasyAccess 2.0 servers.
