The "Dummy" input system is a pseudo input system that does not have any function or configuration properties.

This input system can be used if a scenario does not have its own input system. In practice, for example, it is possible for a scenario not to have an input system and for extraction to take place another scenario. In this other scenario, a dynamic scenario switch (property Process.ScenarioSwitchMacro) is used to switch to the relevant scenario. Processing then starts in the subsequent scenario in the "Process" step. However, the "Dummy" input system is only absolutely necessary in this case if an input worker is defined for the target scenario that expects the configuration of an input system. Alternatively, the assignment of the scenario to an input worker can simply be omitted.
