Good morning Nikhil,

Thank you very much for your comments and for taking my course 😀

The best way to securely remote connect to your Ethernet PLC would be to “VPN” into the network your PLC is on. Note – you'll also have to have the default gateway Ethernet setting in the PLC set correctly for remote access (or even access through a bridge or router) to work.

Hope this helps and thanks again,
