If Robot Config is going to use FTP in active mode (this is true for RI20 with KUKA robot controller) then go to Settings in the menu.

In the "External IP address" field, fill in the IP address of the HMI panel, which is usually 192.168.1.11. Then Save settings.

You also need to modify firewall settings for FTP active mode. In Windows Defender Firewall go to Inbound Rules:

  1. Locate and disable the two firewall rules with name "vpnkit" that block inbound traffic from public network to program: vpnkit.exe

  2. Add a new firewall rule that allows inbound TCP traffic for ports: 5567, 45600-45699
