94 Configuration Manual, 09/2013, C79000-G8976-C182-13
Requirements for configuring connections
● The Ethernet CP was configured in the S7 station with STEP 7 and networked with an
Ethernet subnet.
● As a bus node, the Ethernet CP has an address.
Note
All stations not in the current STEP 7 project must be configured with substitute objects
(for example as "SIMATIC S5" or "Other stations");
or
Use the "unspecified" p

5.2
Connections to partners in other projects
There are various ways of creating connections to partners configured in other STEP 7
projects or with other tools outside the current STEP 7 project:
● Connection using substitute objects such as "SIMATIC S7", "PC/PG" , "SIMATIC PC
Station".
● Unspecified connections
Unspecified connections
Connections to an as yet unknown device (for example a diagnostics unit) are configured as
"unspecified" connections. They can be specified later in the Properties dialog.
You can create an unspecified connection simply by selecting station "unspecified" for the
connection partner when you create the connection. The unspecified connection can be
used in various ways (explained below based on the example of an ISO-on-TCP connection;
ISO transport and TCP connections are analogous):
