Abstract

In order to transmit data on a transmission path to which a control unit and several nodes are connected, the control unit cyclically outputs data in a continuous manner onto the transmission path during the entire transmission cycle time in the form of telegrams by taking into account the transmission standard, the nodes exchanging data with the telegrams during the cycle. The control unit subdivides the transmission cycle into a number of subcycles that have the same length. At least one communication telegram into which a first node can write data for a second node located downstream on the transmission path during the cycle, is sent in each subcycle.
