established by this S7 station. This is the default setting when
the address of the partner is specified.

connection, the option is deselected as default. If you activate
the option, you must also specify the address of the partner in
the “Addresses” tab.
ON: the connection is established actively.
OFF: the connection is established by the partner.
Modifiable
Use for FTP protocol Selecting the option has the following effects:
The TCP connection is now used as an FTP connection.

(Port=21)
”Options” tab: The mode is set permanently to FTP.
The ”Active connection establishment” option is irrelevant
and cannot be set.
Configuration limits: see /2/
Precondition: The option can only be selected for an
unspecified TCP connection.
