Abstract
In a method for generating a switching sequence in an industrial plant which includes components for transferring the plant to an energy-saving state, a state model of the plant is used with regard to the components and information about a task-specific action schema with regard to the components. An extended state model is determined by supplementing the state model with the task-specific action schema using circuit-relevant variables. The switching sequence is generated from a start state to a desired target state by calculating proceeding from the target state back to the start state in the extended state model, and the switching sequence is executed.

A method for generating a switching sequence in an industrial plant which includes components for transferring the plant to an energy-saving state, said method comprising:
- using a state model of the plant with regard to the components and information about a task-specific action schema in form of application-case-based sets of rules composed of model-dependent precondition-effect-descriptions with regard to the components;
- determining an extended state model by supplementing the state model with the task-specific action schema using switching-relevant variables;
- back-calculating in the extended state model from a desired target state of the plant to a start state based on the application-case-based sets of rules;
- generating the switching sequence from a start state to the desired target state based on the back-calculation;
- and
- executing the generated switching sequence.
An apparatus for generating a switching sequence in an industrial plant which includes components for transferring the plant to an energy-saving state, said apparatus being configured to:
- use a state model of the plant with regard to the components and information about a task-specific action schema in form of application-case-based sets of rules composed of model-dependent precondition-effect-descriptions with regard to the components;
- determine an extended state model by supplementing the state model with the task-specific action schema using switching-relevant variables;
- back-calculate in the extended state model from a desired target state of the plant to a start state based on the application-case-based sets of rules;
- generate the switching sequence from a start state to the desired target state based on the back-calculation;
- and
- execute the generated switching sequence.
