| 摘要 |
The invention relates to a method for data transmission in a communication network (1) that is split into a plurality of segments (3), each of which has a transmission medium (7), and has at least one slave subscriber (9). Each segment (3) is provided with a segment master (5), and two respective adjacent segments (3) are connected by a transition region (11). A segment master (5) and a slave subscriber (9), which is situated in the segment (3) of the segment master (5) or in a transition region connecting this segment (3) to an adjacent segment (3), communicate via the transmission medium (7) of the segment (3) of the segment master (5), wherein the segment master (5) assigns the slave subscriber (9) at least one transmission time interval for sending messages, so that the transmission time intervals assigned by the segment master (5) do not overlap. A slave subscriber (9) within a transition region checks, prior to the sending of a message, whether the transmission media (7) of both segments (3) connected by the transition region (11) are free to send a message. |
