This is a rather odd one, and I am probably a bit out of my depth considering some of the other questions on this forum, but I recently purchased an AR-750S for the primary purpose of connecting to the local ethernet network used on industrial automation cells. These cells are always airgapped from the internet.
My main reason is so I can FTP into the robots on these cells, and take backups of them, or edit/load new code onto them via FTP.
For backups I wrote a script that uses the windows ftp cmd to pull everything, but when I try to use the script while connected through the AR-750S, it just hangs when it gets to the ‘mget .’ command while connected to the robot. Another program I use to edit the code while on the robot, Ultraedit, which has a built in ftp browser, always fails to connect. Unfortunately I can’t give more information besides they hang somewhere in the connection process, as they don’t really
When I remove the AR-750S, and connect directly via a wired connection to the same port with the same IP address the router was using, these issues disappear, so I am blaming the router.
Oddly enough filezilla works in both cases.
Is there any setting in the router that would cause this behavior?
