Ftp-Server (File Transfer Protocol) - WAGO 750-370 Manual

4.1.3.3.6

FTP-Server (File Transfer Protocol)

The file transfer protocol (FTP) enables files to be exchanged between
different network stations regardless of operating system.
In the case of the ETHERNET coupler/controller, FTP is used to store and
read the HTML pages created by the user, the IEC61131 program and the
IEC61131 source code in the (programmable) fieldbus coupler or controller.
A total memory of 1.5 MB is available for the file system. The file system is
mapped to RAM disk. To permanently store the data of the RAM disk, the
information is additionally copied into the flash memory. The data is stored in
the flash after the file has been closed. Due to the storage process, access
times during write cycles are long.
Attention
Up to 1 million write cycles are possible for writing to the flash memory for
the file system.
The following table shows the supported FTP commands for accesses to the
file system:
