Abstract

Data transmission in a communication network is performed via a transmission path with which a master participant and at least one slave participant communicate. The master participant outputs messages on the data transmission path with which the slave participants exchange data on the fly. The messages output by the master participant contain datagrams which comprise a control data field and a payload field, where the control data field has a command field and an address field. In the case that at least one message has at least one datagram which is a write datagram in which the command field defines the data transmission procedure to be performed by a slave participant with the payload field as a write procedure, at least the control data field of a further datagram is arranged between the control data field of the write datagram and the payload field of the write datagram.
