FTP transfer of file

[Carla]

I am trying to transfer file/s to an FTP server (with user, login etc.) However, I get the error (FTP code 550 - cannot create file). The error comes from built-in FTP_stor VI. I have attached a copy of my VI. I have checked that I have access to the server and can manually transfer files. Any advice is appreciated.

I ran into this problem a while back and as I recall there are two modes of operation for FTP--active and passive. If you start poking around in some of the lower-level VIs in the FTP drivers you'll see inputs for selecting the mode. However this mode switch was not exposed to the higher-level FTP code that NI shipped.

I do remember that to get the FTP drivers to work I had to use the other mode from the one that was selected by default. I remember that I was getting the same error message you gave.

PS: Just looked at your code and you can see the "active (T)" input on the Send VI. Try wiring a False constant to it. Also connect the error cluster between the FTP Open Session VI and the Logon VI.

I had the same type of error while ftp'ing from a LYNX OS box to a windows box. Labview ftp would consistently add the spurious CR (0x0D) someplace in the file, causing my downstream file parser to barf. I fixed it by changing mode from ascii to binary in the ftp[RETR].vi input...

I can send example code but try playing around with the active/passive and ascii/binary constants.
