Method and apparatus for operating and identifying channels of a redundant communication network

1. A method for operating a redundant communication network with network participants, comprising the steps of:

determining by network participants to which network channels they are connected;

using a telegram for said determining by the network participants to which network channels they are connected;

providing in the network at least one central participant and at least one secondary participant;

providing a primary network channel and a secondary network channel;

communicating between the central participant and the at least one secondary participant during an initialization phase via only said primary network channel, wherein said secondary network channel is not configured for and is never used for communicating between the central participant and the at least one secondary participant during the initialization phase;

exchanging data in the form of telegrams between the central participant and the at least one secondary participant, wherein only after the initialization phase, the central participant transmits telegrams with the same contents using both the primary network channel and the secondary network channel;

wherein the network is a redundant network configured as a network for automation purposes and includes at least one drive and one control unit, wherein said network is part of an automation system based on decentralized control and drive systems comprising a plurality of individual systems that are controlled and driven in a temporally synchronized manner.

2. A method as defined in claim 1 ; and further comprising sending telegrams on all channels after the initialization phase.

3. A method as defined in claim 2 ; and further comprising providing the telegrams on different channels having a same content.

4. A method as defined in claim 1 ; and further comprising transmitting by the central participant a channel identifier, in an anticyclic manner, for channel identification when a new secondary participant is added to the network.

5. A method as defined in claim 1 ; and further comprising including in the network at least one central participant and at least one secondary participant; and transmitting by the central participant telegrams with a channel identifier for channel identification.

6. A method as defined in claim 1 ; and further comprising utilizing by the network topology selected from the group consisting of a ring-type network topology and a line-type-network topology.

7. A device for operating a redundant communication network, comprising:

network participants, wherein the network participants include means for identifying the network channels, wherein the participants include at least one central participant, at least one secondary participant, and at least two channels

a network topology selected from the group consisting of a ring-type network topology and a line-type network topology being in place, the network participants comprising means for determining to which network channels they are connected, using a telegram for said determining, wherein communicating between the central participant and the at least one secondary participant during an initialization phase is via only a primary network channel, wherein a secondary network channel is not configured for and is never used for communicating between the central participant and the at least one secondary participant during the initialization phase, and wherein exchanging data is in the form of telegrams between the central participant and the at least one secondary participant, wherein only after the initialization phase, the central participant transmits telegrams with the same contents using both the primary network channel and the secondary network channel, and

wherein the network is a redundant network configured as a network for automation purposes and includes at least one drive and one control unit, wherein said network is part of an automation system based on decentralized control and drive systems comprising a plurality of individual systems that are controlled and driven in a temporally synchronized manner.

8. A device as defined in claim 7 , wherein each participant includes at least two communication interfaces, each with at least two connections, with each of the connections performing a function selected from the group consisting of an input function, an output function, or both.

9. A network with a device as defined in claim 7 .

10. A data telegram for a network as defined in claim 9 , wherein a subfield of the data telegram includes a channel identifier.

11. A data telegram as defined in claim 10 , wherein it is configured as a data telegram that contains data fields for all slave participants and/or telegrams sent by slave participants that include actual values of a drive controlled by the particular slave participant.
