hi follow the following :

 a-Open the FTP Connection:

• Use the FTP Open VI to establish a connection to your RT target.
• Input the IP address of the RT target, along with any required credentials (username/password).

b. Change Directory (Optional):

• If you need to place the file in a specific folder on the RT target, use the FTP Change Directory VI to navigate to the right folder.

c. Upload the File:

• Use the FTP Put File VI to send the text file. You will need to provide the local file path of the text file and the destination path on the RT target.

d. Close the FTP Connection:

• Finally, use the FTP Close VI to close the connection after the file transfer is complete.

does RT running the FTP Service as default?

i mean if i need to set something in RT before i use ftp to transfer files?

Hi Yuan,

recent LabVIEW (RT) versions don't install FTP by default as it is considered as "legacy technology".

You need to explicitely install the FTP service (using MAX) on your cRIO!

i uesd a stupid method to workaround my problem

1. map rt to my windows pc,as driver Z

2. use copy to vi to copy file to Z

There is no "general method" as each cRIO can be used in a variety of (network/hardware/software) systems…

Suggestions:

• Define a command/response system between your cRIO and your host computer
• Create code in your cRIO program to handle all those host commands
• Send a command to create a new (text) file in the cRIO
• Send the data for the file and save the data in the cRIO
• Send a command to close the file in the cRIO

This would be one possible "program method"…
