Abstract

A receiving logic of a network subscriber can be configured in a first filter setting to forward telegrams having first and second addressing techniques to first and second processing units, with a transmitting logic configured to forward the telegrams to a transmitting port. In a second filter setting, the receiving logic can be configured to duplicate the telegrams and forward to the first and second processing units, with the first processing unit configured to discard telegrams using the second addressing technique and the second processing unit configured to discard telegrams using the first addressing technique. The receiving logic of a third filter setting can be configured to duplicate telegrams and forward to the first and second processing units, with the transmitting logic configured to forward only telegrams using the first addressing technique from the first processing unit, and only telegrams using the second addressing technique from the second processing unit.

First claim

The invention claimed is:

1. A network subscriber for an automation network, which comprises at least one receiving port and at least one transmitting port to which further automation network subscribers may be connected via a data line network,
wherein the network subscriber is configured to receive telegrams using a first addressing technique and telegrams using a second addressing technique via the receiving port and to send them via the transmitting port,
wherein the network subscriber comprises a first processing unit for processing the telegrams using the first addressing technique and a second processing unit for processing the telegrams using the second addressing technique, and
wherein the network subscriber comprises a receiving logic connected to the receiving port and to the first processing unit and to the second processing unit, and a transmitting logic connected to the transmitting port and to the first processing unit and to the second processing unit;
wherein the telegrams using the first addressing technique are realized as passing telegrams for processing by the automation network subscribers, and the telegrams using the second addressing technique are realized as individual telegrams for processing by the automation network subscribers,
wherein the second processing unit of the network subscriber is configured to check in each case on the basis of a target address of the individual telegrams whether an individual telegram is intended for the network subscriber,
wherein, if the target address of an individual telegram respectively matches a hardware address of the network subscriber, the second processing unit is configured to process the individual telegram, and
wherein the second processing unit is otherwise configured to forward the individual telegram to the transmitting logic for output via the transmitting port;
wherein in a first filter setting, the receiving logic is configured to forward telegrams using the first addressing technique received via the receiving port to the first processing unit and to forward telegrams using the second addressing technique received via the receiving port to the second processing unit and the transmitting logic is configured to forward telegrams received from the first processing unit and from the second processing unit, respectively, to the transmitting port, or
wherein in a second filter setting, the receiving logic is configured to duplicate telegrams using the first addressing technique received via the receiving port or telegrams using the second addressing technique received via the receiving port and to respectively forward one telegram to the first processing unit and to the second processing unit and wherein the first processing unit is configured to discard telegrams using the second addressing technique and the second processing unit is configured to discard telegrams using the first addressing technique, and wherein the transmitting logic is configured to forward telegrams received from the first processing unit and from the second processing unit, respectively, to the transmitting port, or
wherein in a third filter setting, the receiving logic is configured to duplicate telegrams using the first addressing technique received via the receiving port and telegrams using the second addressing technique received via the receiving port and to respectively forward a telegram to the first processing unit and to the second processing unit, and wherein the transmitting logic is configured to forward only telegrams using the first addressing technique from the first processing unit to the transmitting port and to discard telegrams using the first addressing technique from the second processing unit and to forward only telegrams using the second addressing technique from the second processing unit to the transmitting port and to discard telegrams using the second addressing technique from the first processing unit.

2. The network subscriber according to claim 1 ,
wherein in the first filter setting, the receiving logic is configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of an embodiment of the telegrams in which a header section of the telegrams using the first addressing technique is configured differently from a header section of the telegrams using the second addressing technique, respectively, or
wherein in the second filter setting, the first processing unit and the second processing unit are configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of the embodiment of the telegrams in which the header section of the telegrams using the first addressing technique is respectively configured differently from the header section of the telegrams using the second addressing technique, or
wherein in the third filter setting, the transmitting logic is configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of the embodiment of the telegrams, in which the header section of the telegrams using the first addressing technique is respectively configured differently from the header section of the telegrams using the second addressing technique.

3. The network subscriber according to claim 1 ,
wherein in the first filter setting, the receiving logic is configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of a fixed time window in which telegrams using the first addressing technique and telegrams using the second addressing technique are respectively received by the receiving logic via the receiving port, or
wherein in the second filter setting, the first processing unit and the second processing unit are configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of the predefined time window in which telegrams using the first addressing technique and telegrams using the second addressing technique are respectively received from the receiving logic via the receiving port, or
wherein in the third filter setting, the transmitting logic is configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of the predefined time window in which telegrams using the first addressing technique and telegrams using the second addressing technique are respectively received by the receiving logic via the receiving port.

4. The network subscriber according to claim 1 ,
wherein in the first filter setting, the receiving logic is configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of a switch-over telegram, by which the forwarding of telegrams using the first addressing technique received via the receiving port to the first processing unit or of telegrams using the second addressing technique received via the receiving port to the second processing unit is switched over by the receiving logic, or
wherein in the second filter setting, the first processing unit and the second processing unit are configured to distinguish the telegrams using the first addressing technique and the telegrams using the second addressing technique on the basis of the switch-over telegram, by which the forwarding of telegrams using the first addressing technique to the transmitting logic is switched over by the first processing unit or by which the forwarding of telegrams using the second addressing technique to the transmitting logic is switched over by the second processing unit, or
wherein in the third
