File management and file access with FTP/FTPS
9
With its file transfer functions (FTP), the Advanced CP provides a useful tool for transferring
files to and from your S7 station.
Files can be transferred both from the PG/PC to the S7 station or initiated by the S7 station
to an FTP server; this could be, for example, a PC/PG station or another S7 station. With the
Security CPs, this can be transferred encrypted with FTPES (explicit mode).
This section will familiarize you with the FTP client and FTP server functionality of the
Advanced CP in the S7 station. The description also applies to FTPS.
Note
FTPS / FTPES
Where the term "FTPS" is used in this documentation, FTPS in the explicit mode is meant
(FTPES).
For a detailed description of the program blocks that you require for file transfer from your S7
station, refer to /10/ (Page 230).
Note
Opening ports
In FTP server mode, make sure that the relevant ports of the CP and the commun
ication
partner of the CP are opened. For more details on this topic and on configured access rights
and security aspects, refer to section
Security when accessing process data (Page 162).
Note
Files only in binary format
When using FTP, always transfer the files in binary format.
