Method and device for exchanging data between at least two stations connected via a bus system
First Claim
1. A method for exchanging data in messages between at least two stations connected via a bus system, comprising the steps of:
- transmitting the messages containing the data by the stations over the bus system;
controlling the messages over time by a first station so that the first station repeatedly transmits a reference message over the bus system at at least one specifiable time interval, the reference message including a time information of the first station, the time interval divided into time windows of specifiable length, the messages transmitted in the time windows;
combining into at least one first cycle a reference message and subsequent time windows until a next reference message; and
stopping the transmission at the end of the first cycle by a stop request occurring at any point in time during the first cycle.

Abstract
A method and a device for exchanging data in messages between at least two stations connected via a bus system, the messages containing the data being transmitted by the stations over the bus system and the messages being controlled over time by a first station in such a manner that the first station repeatedly transmits a reference message over the bus at least one specifiable time interval and the time interval is divided into time windows of specifiable length, the messages being transmitted in the time windows, a reference message and the subsequent time windows until the next reference message being combined into a first cycle, and the first station interrupting the transmission at the end of a first cycle due to a stop request, in particular, a message of the at least second station.

15. A device for exchanging data, comprising:
-
a bus system; and at least two stations configured to exchange the data in messages between the at least two stations connected via the bus system, the stations configured to transmit the messages containing the data over the bus system, a first station configured to control the messages over time and to repeatedly transmit a reference message over the bus system at least one specifiable time interval, the reference message including a time information of the first station, the time interval divided into time windows of specifiable length, the messages transmitted in the time windows, the reference message and the subsequent time windows combined into a first cycle until the next reference message, wherein the transmission is stopped at the end of the first cycle by a stop request occurring at any point in time during the first cycle. - View Dependent Claims (16, 19)

17. A bus system, comprising:
-
an arrangement configured to perform a method for exchanging data in messages between at least two stations connected via the bus system, the method including the steps of; transmitting the messages containing the data by the stations over the bus system; controlling the messages over time by a first station so that the first station repeatedly transmits a reference message over the bus system at least one specifiable time interval, the reference message including a time information of the first station, the time interval divided into time windows of specifiable length, the messages transmitted in the time windows; combining into a first cycle a reference message and subsequent time windows until a next reference message; and stopping the transmission at the end of the first cycle by a stop request occurring at any point in time during the first cycle. - View Dependent Claims (20)
