METHOD FOR DYNAMICALLY CHANGING BETWEEN GROUPS OF ACTIVE PARTICIPANTS IN A WIRELESS DATA BUS SYSTEM

摘要

The invention relates to a method for dynamically changing between groups of active participants in a wireless data bus network having data transfer cycles (“superframe”), wherein the data bus network also comprises only cyclically active participants temporarily entering a passive mode in pause periods, and wherein a group identification of the group to change and a counter value (N) are transferred to each participant per data transfer cycle for preparing for a group change, the counter value (N) is decremented each data transfer cycle (“countdown”), and is selected so large that the duration of all data transfer cycles occurring prior to the occurrence of the group change and comprising a counter value and a group identification is greater than the greatest pause period of an only cyclically active participant in the data bus network, and the participants in the data bus network determine, after receiving the group identification and the status of the counter value (“countdown”), at what point in time the group change is to be performed and which mode is to be assumed after the group change.
