Exemplary controllers in a system are associated with technical entities and are configured to selectively execute tasks in a primary mode when the controllers interact with the associated technical entities with respect to the tasks, and to execute tasks in a secondary mode when the controllers do not interact with the associated technical entities with respect to the task. The system distributes task instructions of a first task to a first controller that is configured to execute the first task in the primary mode, and to distribute the task instructions of the first task to a second controller that is configured to execute the first task in the secondary mode. The system distributes task instructions of a second task to the second controller that is configured to execute the second task in the primary mode.
