S7-1500 CP as FTP server
The functionality described here allows you to transfer data in the form of files to or from an
S7-1500 station using FTP commands. At the same time, the conventional FTP commands
for reading, writing and managing files can also be used.

● RAM of the CP
Name of the directory:
/ram
● Data blocks of the CPU
Name of the directory:
/cpu1 / DBx
"DBx" is the name of the relevant data block e.g. DB10.
● SIMATIC memory card of the CPU
The function is supported as of CP firmware V2.0 and CPU firmware V2.0.
Name of the directory:
/mmc_cpu1
Access to the following folders of the SIMATIC memory card is possible:
– /DATALOGS
– /RECIPES
Note
FTP access to the SIMATIC memory card of the CPU: CPU STOP possible
Note that the cards have a limited capacity If the memory space of the SIMATIC memory
card is completely occupied due to storage of large amounts of data, the CPU changes to
STOP.
• Use a card with adequate storage capacity.
• Avoid writing large amounts of data often to the SIMATIC memory card using FTP.
