Applications & ports

• 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

• 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:
