8.2 Terminology used

Applications & ports

The Application symbolises the function of a device in the »Engineer«. An application can be viewed

as a block that is mostly configurable via parameters and is provided with external connection

points, so-called Ports:

• A device always comes with an application which may be empty (unconfigured).

• Via input ports, for instance setpoints and control commands can be transferred to the

application. Via output ports an application can provide actual values and status messages.

• Examples of applications are "speed control" and "torque control".

Machine application

A function of the system which is implemented by the interaction of several devices in the

»Engineer« is symbolised by a Machine application.

 How to generate a machine application:

• A machine application is generated by defining the applications which form this machine

application by allocation in a first step:

• The second step is to interconnect the ports of the applications assigned with each other and

like this describe the applications between which information is exchanged:
