9.1 Separation of the application and the network
In the »Engineer«, communication between the controllers can be effected via the application level
or the network level.
• The Application level enables the interfaces/ports of the devices to be defined and
interconnected for the respective application.
• In the Network level , transfer-specific parameters can be defined. This includes the creation of
networks, the addition of nodes to networks, and the parameter setting of the process data
objects. ( 205)
• By separating the two levels you can generate an application and decide later on via which
communication medium the information is to be exchanged during the runtime.
• »Engineer« enables you to concentrate on the application.
• The creation of process data objects and the assignment of interfaces (ports) are carried out by
the »Engineer«.
• If you have created an application, you may have to make some minimum settings. This is
referred to in another part of the documentation.
9.1.1 Application level
In the application level, the interfaces of an application, the ports, are defined. The application can
be a program or a permanent application.
• The application can send process data to the outside or receive them from the outside via the
ports.
• The ports are defined in the port editor.  Port editor (ports) ( 155)
• The port editor can be called for both an application on a device and for a cross-machine
application, the "machine application".

Tip!
The machine application serves as a structuring means for the generation of system
modules which already contain a predesigned interconnection.
