Hello,

Can somebody propose a working solution to access the PLC running Codesys over internet ? We would need to log in and change some code on a device that is connected to the internet but is outside our network.

Hi, yes it is possible through a VPN connection e.g. TeamViewer IoT. Have a look here and maybe have a chat with the TeamViewer support
PLC | TeamViewer IoT - TeamViewer
Have a look at video Tutorial 24.1 – TeamViewer IoT how easy the commissionning works (not the VPN part).
