Inter-station communication
In this table, you specify the communications partners of the CP for inter-station
communication. The communications partner is a CP in the partner S7 station.
Connections for inter-station communication run via the telecontrol server.

the section Partner stations (Page 82).
The partner number is assigned by the system. It is required during data point configuration
to assign data points to their communications partners.
You specify the partner CP for inter-station communication with the parameters "Project",
"Station" and "Slot".
Here, enter the project number of the CP in the partner station.
You will find the parameter in the parameter group "Security > CP identification" on the
