Thanks very much for the feedback. After a little digging, it turns out that the DHCP server on our subnet had decided to give my workstation a new IP address that the robot didn't know about. I configured the network connection manually with the correct IP address and it all works as expected. Thanks for the clarification re the 'output' parameter as well; I don't think I quite understood what it does, but all is clear now.
