Abstract: The invention relates to a bus coupler which converts a network-specific telegram arriving from an external network to an internal data telegram which transmits only the payload data from the network-specific telegram. The internal data telegram also contains at least one state information field for internal control information. The internal data telegram is transferred from the bus coupler to an internal bus system to which multiple bus users are connected in series. Each bus user connected to the internal bus system is able to monitor, in a decentralized and preferably autonomous manner, the communication quality of the lower-level bus system, and to initiate actions, depending on the implementation, on the basis of the internal control information received from the bus coupler, the internal control information generated by the particular bus user, and/or the internal control information received from the directly adjacent bus users.

Abstract: The invention relates to a communications entity for communications via a bus-oriented communications network with a control device (101) that is constructed to communicate via the communications network in response to a selection signal according to a first communications bus sub-system or according to a second communications bus sub-system, and a selection device (103) for generating the selection signal as a function of an operating mode of the communications entity, in order to select the first communications bus sub-system or the second communications bus sub-system.

Abstract: A method is disclosed in which data is exchanged via a bus coupler (500) between a network (410) designed for transmitting Ethernet telegrams and a lower-level bus system (420), wherein the bus coupler (500) is connected via a first interface (520) to the network (410) and via a second interface (530) to the lower-level bus system (420), and wherein process data is read in and/or output through at least one bus node (610, 620, 630) of the lower-level bus system (420). Furthermore, a bus coupler (500), a bus node (610, 620, 630), and a control system (10) that are designed for execution of the method are disclosed.

Abstract: The invention pertains to a modular data transmission system with several modules or bus nodes that can be arranged adjacent to one another in a row. The data transmission system comprises a first bus node that features a first transmitter for the wireless transmission of data and an electrical connector, as well as a second bus node that features a first receiver for the wireless reception of data and an electrical connector. Both bus nodes are detachably fixed on a mounting rail such that they are arranged adjacent to one another in a row. The first and second bus nodes are respectively detachably connected to a bus receptacle, wherein each bus receptacle features an electrical mating connector that is coupled to the electrical connector of the respective bus node in the connected state in order to transmit energy, as well as a positioning device for positioning the respective bus node.
