A method for operating a redundant communication network with network participants includes the steps of determining by network participants to which network channels they are connected and using a telegram for said determining by the network participants to which network channels they are connected.

Method and apparatus for operating and identifying channels of a redundant communication network

With a method for synchronization in a communication system that includes a central participant and at least one further participant, at least one of the further participants being synchronized with the central participant, and, to this end, a telegram with synchronization information being transmitted by the central participant to the at least one further participant, particularly efficient synchronization of the at least one participant with the central participant results due to the fact that the telegram is a data telegram.

Communication system and method for synchronization of the same

With a method for synchronization in a redundant communication system that includes a central participant and at least one further participant, at least one of the further participants being synchronized with the central participant, and, to this end, at least two telegrams containing synchronization information being transmitted by the central participant to the at least one further participant, if there is a transmission error involving a telegram containing synchronization information, it is still possible to carry out synchronization due to the fact that, based on the synchronization information contained in the at least two telegrams, resultant synchronization information is obtained and is used to synchronize the further participants with the central participant.

Method for synchronization in a redundant communication system

A method for data transmission between participants communicating by means of a data bus, in which as high a transmission likelihood for additional data as possible is to be assured by providing that in the exchange of data telegrams between the participants within the cycle timepredetermined for one transmission cycle, at least one first and at least one second time slotare used, and the first time slotserves to forward process data and the second time slotserves to forward additional data, and the length of the data telegrams representing the additional data is predeterminable within the length of the corresponding time slot

Method for data transmission

A network station for a data network for receiving external data and for transmitting device-internally prepared data has a repeater for transmitting an external data packet received at a data input to a data output, a first data preparation unit for transmitting an internal data packet generated from the prepared data via the data output, having a switching device for interrupting the data path between the data input and the data output, a control unit that is connected to the switching device in order, in a first operating mode, to block the transmission of the received external data packet via the data output if the internal data packet is currently being transmitted via the data output by the data preparation unit, and to permit the transmission of the received data packet by the repeater via the data output if no internal data packet is currently being transmitted via the first data preparation unit.
