of the rotor spinning device 1 the nodal device 19 19 u2032 does not exercise any further functions besides the management of communications and the supply of the processors 14 14 u2032 with operational voltage by combining processors 14 14 u2032 on one nodal device 19 19 u2032 respectively difficulties are avoided which could otherwise result for example from the connection of more than 300 working stations to a single data bus the data bus 24 is designed as a can data bus and can provide the respective nodal device 19 19 u2032 very quickly with data blocks the can bus is designed for the requirements of the automated rotor spinning machine 1 because of the reduced number of connections with the data bus 24 it is possible to omit entirely or in part the installation of amplifiers such as are required with long data bus lines without endangering interruption proof operations it will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application many embodiments and adaptations of the present invention other than those herein described as well as many variations modifications and equivalent arrangements will be apparent from or reasonably suggested by the present invention and the foregoing description thereof without departing from the substance or scope of the present invention accordingly while the present invention has been described herein in detail in relation to its preferred embodiment it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention the foregoing disclosure is.
