Various embodiments include a computer-implemented method for task-oriented system definition, implementation and operation, the method comprising: importing representative model data including predefined model parameters by an interface component; importing one or more requirements for the model parameters by the interface component; executing measurement and importing measurement results data; aggregating and evaluating imported data, wherein the evaluation is performed depending on the requirements and measurement results data; storing imported data to a computer-readable storage component; operationalizing by adding measurements to the model requirements; and generating a task based on an algorithm performing a functional analysis of the model requirements.

Computer-implemented method and technical system for task-oriented system definition, implementation and operation

The present invention provides a processing unit with an improved ability to coordinate the execution of multiple tasks with varying priorities. Tasks to be executed are assigned both a request condition and a terminating condition, with the processing unit initiating execution of the task with the highest priority whose request condition is satisfied. In general, the processing unit terminates an executing task once the terminating condition of that task is satisfied, and then initiates execution of the next highest-priority task with a satisfied request condition. However, the processing unit may abort execution of a task (other than the highest-priority task) if the request condition of a higher-priority task becomes satisfied. Moreover, the processing unit ensures the highest-priority task does not monopolize system resources by tracking the elapsed execution time and terminating the highest-priority task if this elapsed time exceeds a predetermined maximum, in which case the processing unit initiates execution of the next highest priority task with a satisfied request condition.

A modular programmable controller, comprised of a central processing unit and peripheral units, has a serial bus system in the form of a shift register. The total length of the shift register is equal to the sum of the individual register lengths of the bus interface connections of the peripheral units. The individual register lengths of the bus interface connections are dependent upon command and peripheral units. The individual register lengths amount to between 0 and 40 bits. This results in an exceptionally efficient exchange of information between the central processing unit and peripheral units.
