6.9 Setting up communication via FTP
Setting up a connection for FTP via the user program
For communication via FTP, you need to create the data block of the relevant system data
type yourself, assign parameters and call the instruction directly. This procedure is introduced
below.
FTP client and server functionality
Files can be sent by a CPU to an FTP server and can be received from the FTP server.
Communication with FTP is only possible for the S7-1500 using the CP 1543-1. The CP can be
an FTP server, FTP client or both. FTP clients can also be third-party systems/PCs.
For the FTP server functionality, configure the CP accordingly in STEP 7.
You can use the FTP client functionality to implement, for example, the establishment and
termination of an FTP connection, the transfer and deletion of files on the server. For the FTP
client functionality, use the FTP_CMD instruction.
