  • Patent number: 7852857
    Abstract: A network coupler is provided between a network, on which Ethernet messages can be transmitted, and a plurality of subscribers, the network being linked to an external interface of the network coupler and the plurality of subscribers being linked in series to a ring-type transmission path via an internal interface of the network coupler. For interchanging data, an Ethernet message received via the external interface of the network coupler is forwarded to the internal Ethernet interface of the network coupler and is output onto the ring-type transmission path, each subscriber connected to the internal interface interchanging the useful data intended for the respective subscriber with the Ethernet message circulating on the ring-type transmission path.

  • Publication number: 20090129395
    Abstract: A method transmits data on a transmission path to which a control unit and several nodes are connected. The control unit cyclically outputs data in the form of telegrams to the transmission path, thereby controlling the transmission process in order to continuously output telegrams during the entire transmission cycle time taking the transmission standard into account. The nodes exchanges data with the telegrams when passing through. Further the control unit subdivides the transmission cycle into a number of subcycles having the same length, the control unit transmitting at least one communication telegram in each subcycle into which a first node may write data for a second node located downstream in the transmission path into the communication telegram when passing through.

  • Patent number: 7519076
    Abstract: The invention concerns a data transmission technique for real-time applications and non real-time applications in a communication network comprising several nodes connected by communication channels. The invention is characterized in that the data are cyclically and deterministically transmitted, the data for the real-time applications being processed in priority, such that, during one transmission cycle, all the data for the real-time applications are first sent, then, in the time interval remaining prior to the next transmission cycle, the data for non real-time applications are sent.

  • Patent number: 6167425
    Abstract: The invention pertains to a method and apparatus for implementing a real time control program in a non-real time operating system running on a processor of a PC system, wherein a change of environment from the non-real time operating system to the real time control program and a change of environment from the real time control program to the non-real time operating system are carried out by means of interrupt calls of an internal interrupt source of the PC system in an operating cycle so that run times are allocated to both the real time control program and the non-real time operating system in an operating cycle.
