Setting Up Ftp Connections - Siemens S7-300 Configuration Manual

9.4.2

Setting up FTP connections

Meaning
To run an FTP job sequence between the S7 station acting as the FTP client and an FTP
server, the Advanced CP must establish a connection to the S7 CPU. This connection is
known as an FTP connection.
You can set up an FTP connection as follows:
● During connection configuration in STEP 7 (standard application)
● In the user program with FB CP_CONFIG and the configuration data block.
How to configure FTP connections
To use FTP functionality, you require TCP connections with special properties. Follow the
steps outlined below to configure the connection in STEP 7 / NetPro:
1. Create a TCP connection with an unspecified connection partner for the CPU in your S7
2. Select the option "Use for FTP protocol"

This situation is described below.
There are situations in which it is an advantage to set up the communication connections
not over the configuration interface of STEP 7 but rather program-controlled by specific
applications.
This use case is described in detail in Chapter 8 and in /5/.

Selecting this option has the following consequences:
– The TCP connection is now used as an FTP connection.
– "Addresses" tab: The addresses are specified automatically (Port=21)
– "Options" tab: The mode is set permanently to FTP.
