Enable FTP

Select to use the FTP feature.

Destination

Select either [CF Card] (or [SD Card]) or [USB Storage] as the location for the FTP server folder.

Folder

Defines the external storage folder path, up to 90 single-byte characters long, to share on the FTP server.

If you define the folder as "WebSite" and in Internet Explorer enter the address "ftp://ip_address/", the application displays the "WebSite" folder from external storage.

For example, referencing the CF Card's WebSite folder

  • You can specify only a single folder as the Web Server's root folder.

  • Slashes ("/" or "\") at the end of paths are automatically deleted when saving. Except when the slash ("/" or "\") is the only character in the path.

  • If you want to specify all folders in external storage, leave it blank.

Sets the status when FTP command is received.
When you log in, bit 0 is set to ON.

When you log out, Bit 2 is set to ON and Bit 0 and Bit 1 are set to OFF.

Stores the size of the file to transfer. At log in, previous data is cleared. Units are in bytes.

  • At file deletion, the first bit of the status address does not turn ON/OFF. Only at log in and log out will the status address be updated.

  • The total size of the transfer file storage area is 32 bits. Files transferred that exceed the storage limit of 4294967295 bytes (about 4 GB) cannot be stored. Exceeding this limit may cause instability.

  • The Transfer File Size is the total size of files received and sent. To clear the Transfer File Size, you need to log in again.

  • If data write fails during data transfer, the file being received is deleted but the Transfer File Size indicates the data volume received up to the point of deletion.
