Method for controlling a modular production machine consisting of appliances and components

Modular production machines with appliances and components, controlled by means of projects. A project is the establishment of an arrangement of appliances and modules. A plurality of machine objects is associated with the determined arrangement locations in the project. In this way, the projects have a variability in terms of different machine objects, which is enabled by an engineering system. A control system (a run-time system) can affect a corresponding selection from the options. To enable an economical control of production machines some appliances or components can be selectively replaced by other appliances or modules.
