8.13.3 Connecting ports within the machine application
Interconnection of ports
You can interconnect ports of different devices to each other. Connections are only possible
between ports that can be interconnected. If a connection between two ports is not possible, you
cannot set a connection line.
Via the Connections tab of a machine application you define which applications are to exchange
information via which ports within the machine application.
• If you click an application with the right-hand mouse button, you can select the Go to ports
command to change directly to the Port editor.
• If you connect an output port of an application to an input port of another application, you
express that the element variables of the output port of the first application are to be
communicated to the input port of the second application.
• A connection always has a direction and therefore always has a source and a target.
• Several connections may lead from one port, but only one connection can end in a port.

Tip!
You can also add Ports to a machine application to enable the exchange of information
between different machine applications.
 Adding ports as an external interface ( 179)
Afterwards you can also interconnect these ports, in order to define what information is to
be communicated to the outside.
