Abstract: A method and a device for transferring data in a telecommunication system comprising a data transfer path (8) and devices (21, 22, 1) using the data transfer path for data transfer, data being transferred cyclically in messages (4) between the devices according to at least one cycle having a cycle time, whereby the device (1) is configured to monitor the cyclic communication on the data transfer path; determine, on the basis of the monitoring and the cycle time of said at least one cycle of the cyclic communication, at least one expected occurrence time slot of the cyclic communication; and transmit a message not belonging to the cyclic communication to the data transfer path on the basis of at least one determined occurrence time slot such that it does not collide with one or more messages of the cyclic communication occurring in the determined at least one occurrence time slot.

Abstract: A method and arrangement in a telecommunications system comprising a data transmission path (8), the arrangement comprising devices (1, 21, 221 to 22n) and data being transmitted on the data transmission path between the devices in messages (4, 9) cyclically, whereby one or more of the devices (1, 221 to 22n) are arranged, during one or more first turns, respectively, to set the timing of their own cyclic traffic between cyclic traffic detected on the data transmission path; and one or more of the devices (1, 21, 221 to 22n) are arranged, during a second turn, to transmit a message not belonging to the cyclic traffic to the data transmission path on the basis of at least one determined occurrence time slot of the cyclic traffic such that the message does not collide with messages of the cyclic traffic which occur in the determined at least one occurrence time slot.
