FTP connections to robot stopped working

    I have been backing up my robots with batch file that uses ftp for a while now without issues. Yesterday I tried to tie that batch file to the windows task scheduler and in the process went a little crazy and did multiple backups in a short time while trying to make it work - not sure if that was the starting point of the issue, but it seems that way. Since then, some, but not all, robots do not respond to Ftp anymore. I can still ping them and even use the webserver.


    Any idea what might be happing? If we wouldn't run production 24/7 I would reboot the controller, but did not have the chance yet.

    It is possible to crash the ftp server on the robot without the rest of the robot going down. I've done it a few times. A reboot does fix it.


    Another option may be to restart the service on robot, which is under host comm, then servers in the details tab. I haven't tried this though.

    Check out the Fanuc position converter I wrote here! Now open source!

    Check out my example Fanuc Ethernet/IP Explicit Messaging program here!

    I tried to restart the ftp server, now the teach pendant is frozen :uglyhammer2:


    At least the robot still runs, I will try restarting later. Thanks for the tip.


    edit: restart helped

    This has happened a few times. Restart is the only one that helped then.

    The reason why FTP crashes I have not found. In our system, the "high-level control" is talking a quite bit with the robot over FTP.
