  • control and communication system comprises one or more data buses, which enable communication in the sense of a data transmission between the central control device, the drive control device, the section control devices, the workstation control devices, the maintenance device control devices and / or optionally existing further control devices.
  • a data bus is generally a system for data transmission between several participants via a common transmission path, in which the participants are not involved in the data transmission between other participants.
  • Data buses generally consist of at least one physical bus line and the bus users connected thereto, also called nodes, which in the case of a generic textile machine can be the abovementioned control devices.

  • the maximum length of the bus lines is inversely proportional to the bandwidth used on a data bus.
  • Generic textile machines are now produced usually order-related with a variable number of sections. For a long time now there has been a need to increase the maximum number of sections and thus the number of jobs. On the one hand, however, this causes an increase in the total amount of data to be transmitted by the communication system, which in itself would speak for an increase in bandwidth, on the other hand, the data bus lines due to the ever-increasing textile machines also physically longer and longer, which in itself a reduction in bandwidth would suggest.
  • Known control and communication systems therefore limit the maximum number of sections or jobs of a generic textile machine.
  • Object of the present invention is to provide a textile machine whose control and communication system is suitable for a large number of sections or jobs.
  • the object is achieved by arranging at least part of the bus topology components in the longitudinal direction of the textile machine in a central region of the textile machine.

  • each maintenance device bus line comprises a movable section which leads from the maintenance device to a machine-fixed connection device arranged centrally in the textile machine.
  • This movable portion necessarily has a length which corresponds to half the length of the textile machine, to allow the process of the textile machine up to both end racks.

  • the bus topology components are designed as repeaters or as bridges.
  • Repeaters are generally bus topology components which connect bus lines of a data bus.
  • the bus lines connected by a repeater are each electrically independent segments of a data bus, which can each be terminated with corresponding terminating resistors, so that no reflections occur on the bus lines.
  • the repeater corresponds to a line with a corresponding delay.
  • the real-time behavior of the data bus is determined by the Use of repeaters not affected because it corresponds to the transmission behavior of a network, which consists only of lines.
  • the service facilities are nodes on a data bus including the maintenance device bus lines, the repeaters, and the common bus line.
  • a data transfer between the maintenance facilities and other control devices of the textile machine is possible almost in real time, which is advantageous, for example, in a piecing process in which the actuators of the respective maintenance device and the respective spinning station must be controlled exactly matched.
  • a bridge is generally understood to mean a bus topology component which can connect different logically separated data buses for data exchange. It is based on the Store (Modify) Forwarding principle, where data is received from a data bus, if necessary, adjusted for the protocol and sent to another data bus. Compared to repeaters, a bridge enables the maximum size of the control and communication system to be increased, since the data buses connected by them each operate autonomously. In this way, more sections can be provided. With the aid of conversion rules, also called gateway tables, received bus telegrams can be forwarded or filtered out under another identifier.
  • the data bus utilization can be reduced to the data buses connected by the bridge of the textile machine, so that, for example, to a section connecting the data bus more sections can be shot without the bus is overloaded, because telegrams, which are only for the maintenance facilities of interest are not even on the data buses connecting the sections arrive.
  • a different protocol can be used in each case on the separate data buses thus created.
  • different bandwidths can be provided on the separate data buses. This also meets the desire for longer textile machines.

  • the maintenance device bus lines are designed as trailing cables.
  • a towing line is generally a flexible line, which is protected by a likewise flexible guide device, also called a drag chain, and which extends from a machine-fixed connection device to a moving part of a machine.
  • Trailing cables have a long service life because the bending radius can be kept above a permissible minimum radius by the drag chain.

This has the advantage that a fault on one of the bus lines does not lead to the failure of the entire system.
