Abstract: A first participant transmits a clocked data sequence to a second participant of a communication network, wherein one data unit of the data sequence is transmitted per clock cycle by the first participant and wherein the data sequence contains a datagram as a write datagram which contains a header, an intermediate field following the header and a data field following the intermediate header, wherein the header, the intermediate field and the data field in each case have one or more data units. The second participant reads the header of the datagram, defines input data depending on the content of the header within a response time, and records the input data in the datagram while the data sequence passes through the second participant. The length of the intermediate field of the datagram is matched to the clock frequency of the data sequence and the response time of the second participant.

Abstract: A method for operating a communication network comprising a master and a number of subscribers. A message comprising a data field is transmitted by the master, wherein at least one of the subscribers, on receiving the message, reads data out of the data field of the message, and forwards the message to at least one other one of the subscribers after the readout, and wherein the at least one other one of the subscribers, on receiving the message, writes data into the data field.

Abstract: A communications network comprises a plurality of participants. A first participant transmits a message repeating sequence of N?2 successive messages to a second participant. An action which can be performed by the second participant is assigned to each message in the sequence. The first participant begins to transmit one of the N messages at N successive transmission times T_I (I=0, . . . , N?1). Each of the N messages contains a field defining a waiting time assigned to the respective message W_I=T_(N?1)?T_I+?W_I (I=0, . . . ,N?1), where ?W_I is a non-negative tolerance time. The second participant selects one message from among the messages in the sequence which are successfully received by the second participant as a useful message, measures a time elapsed since reception of the useful message, and performs the action assigned to the useful message when the elapsed time has reached the assigned waiting time.

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.

Abstract: A method for operating a node in a communications network comprises the following steps: The node receives a reference time via the communications network. A transmit clock of the node, which was determined for an earlier clock cycle on the basis of a local clock of the node, is compared with the reference time. The local clock of the node is corrected on the basis of the comparison result. On the basis of the corrected local clock a transmit clock is determined to be used by the node for the current clock cycle.

Abstract: In a network, a control node is connected to a plurality of network subscribers via a closed ring-shaped data path, wherein the network subscribers form a chain, starting from the control node, with a head subscriber as a termination for the chain.
