TFTP (Trivial File Transfer Protocol) is a very simple file transfer protocol, but be aware it has nothing else in common with the ordinary FTP protocol. The first implementations and work on TFTP had been done around 1980. Since it is so simple and memory efficient, it is easy to implement even for small scale embedded applications.
In order to correctly work with TFTP the appropriate tftp-daemon must be started. To launch this daemon-process establish a telnet session to the device and start the process with the command
starttftp
Right after this you are able to transfer files to and from your Festo SBO-smartcamera.
TFTP [-i] host [GET | PUT] source [destination] -i Specifies binary image transfer mode (also called octet). In binary image mode the file is moved literally, byte by byte. Use this mode when transferring binary files. host Specifies the local or remote host. GET Transfers the file destination on the remote host to the file source on the local host. PUT Transfers the file source on the local host to the file destination on the remote host. source Specifies the file to transfer. destination Specifies where to transfer the file.
