Abstract
The invention relates to a method for transferring data between a mobile component and a controller of an automation system with a link for linking the component to the controller. The component is assigned a memory area in the memory of the controller, in which data to be transferred to the component is stored and copied into memory areas assigned to all links, so that all links provided for communication with the component have the current data available to them, and into which current data is copied by the component out of the memory area of the link in the radio cell of which the component is currently located. For a user application running on the controller of the automation system a handover of the component between different radio cells is transparent, since the application merely accesses the always up-to-date component data in the memory area assigned to the component.
