Configuring Communication Connections
Handling Connections in a Multiproject
Interproject connections to a specified partner (for example, a CPU) are created in the same way as connections within a project (identical procedure). The dialog for selecting the connection partner has been extended and allows you not only to select the endpoint (module) but also the project within a multiproject to which the endpoint belongs.
The consistency of interproject connections is retained when you work with the projects of the multiproject:
SInterproject connections within a multiproject are implicitly broken when a project is taken out of the multiproject for distributed editing and the connection partner is located in the removed project.
SWhen the removed project is returned to the multiproject, STEP 7 automatically merges the broken connections consistently.
Connections to Non-S7 Stations using Substitute Objects
If you want to configure connections to devices or stations that are not S7 stations, select a station of the type “SIMATIC S5”, “PC/PG” or “Other Station” as the destination station.
By creating these stations in NetPro and networking them, you have already specified the node addresses (MAC or IP addresses) of the two stations. You must specify the TSAP (Transport Service Access Point) for the destination station.

4.3.2Connections 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:
SConnections using substitute objects such as “SIMATIC S5”, “PC/PG” , “SIMATIC PC Station” or “Other Station”.
This method is described in the section above.
SUnspecified connections
SSTEP 7 object ”Partner in other project” (multiproject)
With this method, a connection is reserved in both subprojects that can be synchronized later by the system when the partner project is included in the multiproject.
