The panel PC's Ethernet port is configured by default with a static link local IP address of 169.254.1.1. The link local address allows you to directly connect an Ethernet cable between a PC and the panel PC without the need for additional hardware, such as a hub, switch, router, etc.
With just a PC (e.g. a notebook), an Ethernet cable, and with the SSH server enabled, the Ethernet Link Local address can be used to access and administer the panel PC both at development time, and when deployed in the field.
Examples:
ssh admin@169.254.1.1 to run commands on the panel PC.scp /path/to/file admin@169.254.1.1 to copy files to the panel PC.scp admin@169.254.1.1:/path/to/file . to copy files from the panel PC.Use FileZilla Client if you prefer having a GUI to transfer files to and from the panel PC over this link local address.
To change the link local address, or disable it entirely, see Network Configuration.
