Binding Connection
A Binding connection is a connection that requires both its connections to have the same values. This kind of connection can be used only on Usage items. In a Binding connection, the output parameter of one Action usage item may be bound to the input parameter of another Action usage item, which indicates that the values of source output parameter and the target input parameters of two Action usage items are the same.
This can also be used in a nested setting, such as, an input parameter of an Action usage can be bound to the input parameter of a nested Action usage, and the output parameter of a nested Action usage can be bound to the output parameter of its containing Action usage, passing the values of the output parameter outside the nested structure.
Creating a Binding Connection
To create a binding connection:
1. On the System Structure Diagram ribbon toolbar, in the Flows section, click the 
Binding button.
Binding button.2. On the diagram, click the first item and then the second item that you want to have equals values.
The two items are now bound and will now have equal values in the model.
