Configuring Connections
"Address Details" Dialog Box for S7 Connections to a Partner in a different
Project
In the dialog boxes for the connection properties (Properties S7 Connection dialog
box and Address Details dialog box) of an unspecified partner, you have to enter or
select the address (of the interface), the end point of the connection (rack/slot), and
the connection resources of each "Other Side" (that is, of the connection partner).
Example: The following configuration is a prerequisite:
The stations are in different projects. The CPU as connection end point is in the
central controller (rack 0) slot 4 in both projects. Both stations are networked by
means of the PROFIBUS interface of a CP.
The following table shows which supplementary information is required for the
configuration shown in order to enable a connection setup in operation.
