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.

Abstract: In an automation network comprising a plurality of network segments, fragmenting subscribers that support a fragmentation method as well as standard subscribers that do not support the fragmentation method can be provided for in the network. A distribution node in the automation network has at least one input/output interface that is in communication with a network segment. The switching unit in the distribution node checks whether a subscriber in a network segment to which a telegram is to be sent supports the fragmentation method, and whether the telegram to be sent is fragmented. If the subscriber does not support the fragmentation procedure and the telegram to be sent is fragmented, the switching unit in the distribution node assembles the telegram fragments to form the telegram and then sends the assembled telegram on to the subscriber.

Abstract: A control-cabinet system has a base module and at least one functional module. The base module has a base housing with a first housing face and a second housing face. The functional module has a functional housing with a housing underside, where a circulation channel is arranged. Air flow may be circulated in the circulation channel, where each base connection element comprises circulation openings which are fluidically connected to the circulation channel. The functional connection element comprises coupling openings fluidically connected to an interior of the functional housing. The coupling openings are coupleable to the circulation openings, in which a fluidic connection exists between the circulation channel and the interior of the functional housing. A fluidically closed circulation circuit comprising the circulation channel and the interior of the functional housing is formed, in which air flow may be circulated.

Abstract: A base module for a control-cabinet system includes a housing with a first housing face and further housing faces, the first housing face having a grid of openings. The housing has connection elements for functional modules, the connection elements each being arranged in the region of the openings of the first housing face, the connection elements comprising data connections, extra-low voltage connections and low-voltage connections. The data connections are interconnected by a data line of the base module and a field-bus connection is provided for the data line, where the data line is arranged within the housing. An extra-low voltage line and a low voltage line are arranged within the housing, where the extra-low voltage line is connected to the extra-low voltage connections and the low voltage line is connected to the low voltage connections.

Abstract: A control-cabinet system includes a base module and a plurality of functional modules. The base module housing has a face with openings, first connection elements and second connection elements. The first connection elements provide data and extra-low voltage connections, and the second connection elements provide low voltage connections. The first connection elements are arranged within the housing, in the area of the openings. The data connections are connected to a data line, the extra-low voltage connections are connected to an extra-low voltage line, and the low voltage connections are connected to a low voltage line. The functional modules each have a housing, an electronic circuit, and a module connection element connected to the electronic circuit. The module housing has a face with an opening. The module connection element comprises a first plug-in element extending through the opening, and adapted to engage the first connection elements of the base module.

Abstract: A method is provided for operating an automation system having a first controller and a second controller and an external data infrastructure with a message-distributing module. The method includes defining a first communication network and identifying the first controller and the second controller as first communication subscribers of the first communication network via the message-distributing module, sending out a first network message via the first controller to the message-distributing module of the external data infrastructure, identifying the second controller as the first communication subscriber of the first communication network addressed via the first controller using the message-distributing module, forwarding the first network message sent out by the first controller to the second controller via the message-distributing module, and receiving the forwarded first network message via the second controller. Further, a data infrastructure system for execution of the method for operating an automation system is provided.

Abstract: A method for routing telegrams in an automation network with network subscribers interconnected via a data line network. At least network subscriber is a master subscriber, which sends telegrams to the network subscribers via the data line network. At least one network subscriber is a network distributor having a plurality of input/output ports, where input/output ports to which segments with further network subscribers are connected are designated as end ports. The master subscriber assigns a port address to each end port, and assigns the port address as an identifier to a telegram intended for processing for a segment with further network subscribers. If the network distributor receives a telegram with a port address of an end port of the network distributor as an identifier, the network distributor outputs the telegram directly via the input/output port of the network distributor corresponding to the end port of the port address.

Abstract: A method is described for operating a communication network with a plurality of subscribers. Data exchange between the subscribers takes place in the form of telegrams, which comprise data sections. The subscribers interpret an end portion of the telegrams as a check value for the absence of errors in preceding data sections. The telegrams are processed in pass-through, so that the telegrams are forwarded to a respective next subscriber while being received. If an error is detected when receiving a telegram, the subscribers send the telegram to the next subscriber with a characterizing data section at the end, so that the telegram has an end portion representing an invalid check value. The telegram is characterized by the characterizing data section, which is part of the end portion, so that the telegram is not to be considered as an initial error but as a subsequent error.

Abstract: An automation network with network subscribers is provided, in which the network subscribers are interconnected via a data line network. At least one network subscriber is configured as a master subscriber, which is adapted to send telegrams via the data line network. At least one network subscriber is configured as a network distributor, which is adapted to route telegrams. The network distributor has a plurality of input/output ports, and is connected to the master subscriber via a first input/output and data line network. The master subscriber is configured to use a telegram element to indicate that the telegram is enabled for processing by the network subscribers. In addition, the network distributor is configured to process a telegram received via the first input/output port when the telegram element indicates enablement of processing of the telegram by the network subscribers.
