Transferring Files from a FieldPoint FP-20xx through an FTP Server

You can use the FP FTP VI to transfer files to and from the FP-20xx Flash memory using the FTP server on the FP-20xx. The FP FTP VI also provides remote file deletion and directory creation functionality. You must have the LabVIEW Internet Developers Toolkit installed to run the FP FTP VI. Use the FP FTP VI to perform the following tasks:

• Transfer a file to the FP-20xx
• Retrieve a file from the FP-20xx
• Delete a file from the FP-20xx
• Create a new directory on the FP-20xx

Accessing Files Using the FTP Addressing Protocol

You can use a Web browser to access the files using the FTP addressing protocol as shown in the following figure.

Transferring a File to the FP-20xx

To transfer a file to the FTP server on the FP-20xx using the FP FTP VI, follow these steps and refer to this figure:

1. Launch the FP FTP VI.

2. In the FP-20xx IP Address field, enter the IP address of the FP-20xx module.



3. If the FP-20xx module has a network password, enter the user name in the User field. Enter the network password in the Password field. If the FP-20xx does not have a network password, you can leave the User and Password fields blank. For more information about security for the FP-20xx, refer to the FieldPoint Explorer Online Help.

FP FTP.vi
I tried downloading the FT FTP.vi. It searches for several sub VI's such as FTP Logon that it can't find. I had just upgraded to LV 8.0
