Method for Assigning Data Messages to Time Slots in a Wireless Data Bus System Having Hidden Subscribers

Abstract

A method for assigning data messages to time slots in a wireless data bus system having hidden subscribers (“hidden nodes”), wherein each subscriber is initially assigned at least one time slot for exclusive use per transmission cycle and the time slot can be engaged by another subscriber for use in the event of non-use by the subscriber. Moreover, an engagement matrix is provided which records, for each subscriber, those time slots of other subscribers for which engagement is permitted in a data message cycle. In accordance with the invention, the engagement matrix is configured to block at least the engagement of the time slot of another subscriber for a subscriber if it is another subscriber (“hidden node”) that cannot be reached by radio by the subscriber.
