The invention relates to a method for tolerating the breakdown and/or decoupling of at least one network node in a communication network used for controlling and/or adjusting the movement of a plurality of machine parts, for example the rotation bodies in a printing machines, machine tools and other production machines, wherein the network is operated according to a closed single or multiple ring structure, in which each node communicates with the transmitter or the port of a first adjacent node by means of a receiver or a first port and with the receiver or the port of a second adjacent network node by means of a transmitter or a second port, the closed ring structure is preserved in the case of the breakdown or decoupling of at least one node, at least one network node is coupled to the network by means of a data path switching device which is actuated, in the case of the breakdown or decoupling of said node, in such a way that the communicating nodes, which exist in the network and are arranged next to each other in the ring structure, interact in communication by means of the port or respective transmitter thereof after the breakdown or decoupling.
A method for tolerating the breakdown or decoupling of at least one network node (2), wherein the network is operated according to a closed single or multiple ring structure, in which each node (2) communicates with a transmitter (TX) or the port (12) of the first adjacent node (2) by means of a receiver (RX) or the first port (11) and with the receiver (RX) or the port (11) of a second adjacent network node (2) by means of a transmitter (TX) or a second port (12), and the closed ring structure is preserved in the case of a breakdown or decoupling of at least one of the nodes (2), characterised in that at least one of the nodes (2) is coupled to the network via a data path switching device (1) which is actuated in the case of a breakdown or decoupling of said node (2) in such a way that the communicating nodes (2) which exist in the network and are arranged next to each other in the ring structure interact in communication by means of the relevant port (11, 12) or transmitter (TX) and receiver (RX) thereof after the breakdown or decoupling.
A data path switching device, with internal input and output side data connection means, characterised in that the data connection means comprise at least one longitudinal receiver (3) and at least one transverse receiver (4) as well as at least one transverse transmitter (5) and at least one longitudinal transmitter (6), and wherein at least the transverse receiver (4) is equipped with monitoring means for communication capability of an external transverse transmitter or network node (2) for generating a binary communication flag (link), as well as at least one longitudinal switch (S33, S34) to be activated by means of the communication flag (link) between the output of the longitudinal receiver (3) and the input of the longitudinal transmitter (6), so that a number of the same from the longitudinal receiver (3), the longitudinal switch (S33, S34) activated to close, and the longitudinal transmitter (6) bridge at least that transverse receiver (4) generating the communication flag when a communication flag indicates a lack of communication capability in the external transverse transmitter or network node (2).
port A multi-port connection means (26) for the communication technical connection of a plurality of network nodes (2), network or field bus segments (27), separate networks and/or other network configurations, characterised by a plurality of communication ports (11, 12, 21, 22, 23) and one or more ring-shaped organised communication systems, from which the communication ports (11, 12, 21, 22, 23) coupled with the same extend in a star-shaped way, and the connection of the network nodes (2), the field bus segments (27) or other network configurations enable a star topology with a ring-shaped structured centre in this way.
A communication network, structured and organised according to a single or multiple ring topology, with which a plurality of network nodes (2), network or field bus segments (27), separate networks or other network configurations are coupled, characterised in that the ring-shaped network comprises a plurality of star-shaped communication ports (11, 12, 21, 22, 23) extending in an outward direction for coupling the network nodes (2), network or field bus segments (27), separate networks or other network configurations to form a star topology, wherein the ring-shaped network forms the centre.
