Establishment With this option, you specify whether the connection is established by
this S7 station. This is the default setting when the address of the
partner is specified.
ON: the connection is established actively.
OFF: the connection is established by the partner.
If you selected partner “unspecified” when you created the
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.
Note:
Please note the effects on the mode. If you want to use the FETCH
or WRITE mode (refer to the ”Options” tab), the mode must be set to
”Passive”.

Connection Name (Reference) – Only in Multiproject
If you create a connection to a partner in another project, that has not yet been
merged with the current multiproject, you must enter a connection name as
reference. Interproject connections can then be joined up based on this reference.
As soon as the connections have been brought together, the connection name
(reference) can no longer be entered.
