Definitions
- the invention relates to a data bus with the features of the preamble of patent claim 1
- Such a data bus is described in DE 19720401 A. It is used, for example, in buildings to connect the various electrical switches, power consumers and the like of a building to one another in terms of circuitry and to convey control commands of the participants to one another.
- Other applications are the networking of machine controls in the industrial field , for example for a production line, data buses in aircraft for the various drive and control components as well as land vehicles with the appropriate devices for switching, reshaping and consuming electrical energy
- a synchronization master with a predetermined clock frequency is output by a bus master described, also be variable and depend on the broadcasting act and also on the extent to which the data bus was used by the hierarchically higher messages Problems can arise if the clock generator fails. Switching on a replacement clock generator is complex and problematic, since the activation of the replacement clock generator usually requires a certain time in which the bus communication may be interrupted or at least disturbed
- the invention has for its object to provide a data bus of the type mentioned, which ensures practically uninterrupted bus communication even if the clock generator fails
- the subscriber with the highest priority takes over the role of the clock generator.
- the subscriber who is also acting as the clock generator then has the highest priority a double function He continues to send out his message and this also serves as a quasi clock pulse for the other participants of the bus.
- the latter relates to the possibility specified in claim 2 that the highest-ranking participant only sends out its message regularly if it does not receive a synchronization signal normally sent by a clock generator, as in the alternative mode of operation, in which the highest-ranking participant also in each cycle sends a functioning clock, the highest-ranking participant can start its transmission without interrupting the data communication
- a synchronization signal normally sent by a clock generator as in the alternative mode of operation, in which the highest-ranking participant also in each cycle sends a functioning clock
- the invention also offers the possibility of completely dispensing with a separate clock generator, provided that the highest-ranking subscriber goes to the data bus at regular, regular intervals
