Project
12.12.1 Connection Types for Connection Partners in the Same Project
Selecting the Connection Type for Connection Partners in the Same Project
The connection type is dependent on the subnet and the transfer protocol via
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.
