12.13 Configuring Connections to Partners in Other Projects
12.13.1 Connection Types for Partners in Other Projects
Selecting the Connection Type to Communication Partners in Other Projects
When you have set up a multiproject, you can then configure interproject
connections.
The connection type is dependent on the subnet and the transfer protocol through
which the connection is established and on the automation family to which the
connection partners belong.
The blocks (SFBs, FBs, or FCs) you can use depend on the connection type.
The following table should make it easier for you to select the connection type for
the connection you want to establish.
