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 method for controlling an automation system having control redundancy is provided. The automation system has at least a first controller, a second controller and a plurality of field devices connected to the first and second controller via a data bus, with the first and second controller configured to cyclically control an automation process of the automation system. The method comprises cyclically controlling the automation process via the first controller, determining a malfunction of the first controller during an (n+x)-th control cycle, where the (n+x)-th control cycle is carried out x control cycles later in time than the n-th control cycle, and sending out an n-th set of output data via a second input-output unit of the second controller to the plurality of field devices in the (n+x)-th control cycle, for controlling the automation process. An automation system is configured to carry out the method.

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.

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 switch-cabinet system, having a plurality of communication units and connection elements for a plurality of functional modules. The connection elements are configured to engage in module-connection elements of functional modules. Each connection element has at least one data connection. Each communication unit is in each case connected to at least one data connection of a connection element. The communication units are connected to one another by a data bus. The base module has a first field-bus connection. The data bus is connected to the first field-bus connection to connect the communication units to a field-bus.

Abstract: A method for transmitting data in an automation network by telegrams, where the automation network comprises a master subscriber, slave subscribers and at least one unlocker, connected to each other via a data-line network. The slave subscribers are divided into segments. The master subscriber sends locked telegrams for processing by the slave subscribers, each having a telegram identifier used to assign a locked telegram to a segment. At least one segment is assigned to at least one unlocker. If the unlocker receives a locked telegram, the unlocker checks, by the telegram identifier in the locked telegram, whether the locked telegram for the assigned segment is intended to release the locked telegram, as an unlocked telegram for processing by the slave subscribers, provided that the locked telegram is intended for the segment assigned to the unlocker.

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.

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 for data communication between subscribers of an automation system includes a first passive subscriber and a second passive subscriber receiving a write request sent by an active subscriber, determining a first transmission time point for transmitting a first reply message by the first passive subscriber, transmitting the first reply message at the first transmission time, and receiving the first reply message. The method also includes determining a second transmission time for transmitting a second reply message by the second passive subscriber, transmitting the second reply message at the second transmission time, receiving the second reply message, and interpreting the first reply message and the second reply message as segments of a data packet.

Abstract: A method for synchronizing time in an Ethernet-based network having a master network subscriber and a slave network subscriber includes sending out a first telegram via the master network subscriber, where the slave subscriber receives the first telegram at a first receipt time value of a local system time and stores the first receipt time value. The method can also include reading out the first receipt time value via the master subscriber, sending out a second telegram by the master subscriber, where the slave subscriber receives the second telegram at a second receipt time value of the local system time and stores the second receipt time value, and reading out the second receipt time value via the master network subscriber. A speed parameter of the local system time can be calculated from the receipt time values via the master network subscriber, and transmitted to the slave subscriber.
