Fanuc FTP problem

Hello,

I have a Makino v33 with a Professional 3 Fanuc control. A couple of years ago we began to have trouble with the FTP server. In the middle of transferring a file form the PC to the control it would drop the connection. We've swapped out the cable, the computer, tried both physical Ethernet ports, the new router, direct cable without a router, and even a new PCMCIA card.

I can PING the machine from any computer but the FTP server does not respond to connection request. Only way around it is to power cycle the machine. Any suggestions on how to fix it?

Thank you,
Ivan

I am not familiar with your environment specifically, but I do know a little about FTP. ;)

What FTP client are you using? Try setting it to passive.

What OS is your client PC? Verify your MTU is set to match your machine.

Is the PCMCIA ethernet card on the machine 10, 100, or 1000 base-t. Is it full duplex or half? Some older ethernet cards are 10 base-t and can flip/flop duplex randomly when connected to a modern switch. If your switch is managed you should look the port statistics to see what's happening.

You said you put a new PC card in the control. Did you do a DSFORMAT?
What mode are you running your DS in? Buffer/Storage/FTP?
Have you tried WinSCP for an FTP server on your PC?
Check the Data Server function parameters 921 - 923 for host OS setting. Heck, may as well check ALL the DS parameters against the original setting from the factory.
0, 100, 904 - 970. Manual is B-64014EN
