8.11 Port editor (ports)
The port editor (tab Ports) serves to create and visualise ports.
• A port is an interface which sends and receives data at runtime via an application. The data
transferred via port represent a group of inseparable pieces of information which are sent and
received in one piece.
• Most applications have ports which are already fixedly predefined.
• The port editor can both be called for an application on a device and for a comprehensive
application (machine application) via the Ports tab.
