A configurable system for automating a control sequence, in particular a motion sequence, has several components which exchange in regular time intervals during the control sequence with each other information via communication relationships. The system selects exactly one system project design from a plurality of system project designs based on the topology and functionality of the components. Each component of the system has a component project design, which is used by the system to design the components according to the corresponding component project designs. Each component arranges the communication relationships of the other components according to its own component project design.

Project design method

The present invention is directed to a method of operation and a control program for a central unit (e.g., CPU) in an automation system repeatedly executing a control program that is stored in the central unit and comprises at least two subprograms. A single instance of execution occurs within a cycle time which is stipulated by the control program. The central unit executes only one of the subprograms&#x2014;the activated subprogram&#x2014;at a time. The cycle time is independent of the activated subprogram, is shorter than the time required in order to execute all of the subprograms, and is at least as long as the longest time period required in order to execute one of the subprograms once.
