20090083464 | INTERFACE UNIT AND COMMUNICATION SYSTEM HAVING A MASTER/SLAVE STRUCTURE - An interface unit is provided for a communication system comprising a master unit and a plurality of slave units serially connecting the master unit via a double ring structure comprising a first communication path and a second communication path. The interface unit comprises a first switching unit, which is configured to output information signals received by the master unit as a first information signal to the first communication path and as a second information signal to the second communication path; and a second switching unit, which is configured to forward the first information signal circulating on the first communication path and second information signal circulating on the second communication path to the master unit. | 03-26-2009 |
20090129395 | METHOD, COMMUNICATION NETWORK, AND CONTROL UNIT FOR THE CYCLICAL TRANSMISSION OF DATA - A method transmits data on a transmission path to which a control unit and several nodes are connected. The control unit cyclically outputs data in the form of telegrams to the transmission path, thereby controlling the transmission process in order to continuously output telegrams during the entire transmission cycle time taking the transmission standard into account. The nodes exchanges data with the telegrams when passing through. Further the control unit subdivides the transmission cycle into a number of subcycles having the same length, the control unit transmitting at least one communication telegram in each subcycle into which a first node may write data for a second node located downstream in the transmission path into the communication telegram when passing through. | 05-21-2009 |
20100111082 | Packet Switching Device and Local Communication Network With Such a Packet Switching Device - A packet switching device comprises a network interface configured to send and receive data packets via a communication network, a plurality of string interfaces configured to transmit and receive data packets to/from a plurality of participants and a switching unit connected to the network interface and to the plurality of string interfaces. The a switching unit comprises a control unit configured to control a data throughput. The control unit comprises an interface association table which determines that data packets received via the network interface are mandatorily outputted via the string interfaces and the data packets received via the string interfaces are mandatorily outputted via the network interface. | 05-06-2010 |
20100146176 | DATA TRANSMISSION METHOD, SERIAL BUS SYSTEM, AND SWITCH-ON UNIT FOR A PASSIVE STATION - In a serial bus system data in the form of telegrams, representing process images of control tasks of the active station, are transmitted to the connected passive stations, and the process data are allocated to the process images in the passive station. | 06-10-2010 |
20120089855 | CIRCUIT AND METHOD FOR AN UNINTERRUPTIBLE POWER SUPPLY OF ELECTRONIC MODULES - A circuit for uninterruptible power supply, wherein the circuit can be connected to an energy supply and a load and includes a capacitive energy store, a changeover switch, a charging device, a charging control device, a voltage monitoring device, and a discharge device. | 04-12-2012 |
20150295727 | METHOD FOR OPERATING A COMMUNICATION NETWORK AND COMMUNICATION NETWORK - A method for operating a communication network comprising a master and a number of subscribers. A message comprising a data field is transmitted by the master, wherein at least one of the subscribers, on receiving the message, reads data out of the data field of the message, and forwards the message to at least one other one of the subscribers after the readout, and wherein the at least one other one of the subscribers, on receiving the message, writes data into the data field. | 10-15-2015 |
20150365252 | NETWORK DISTRIBUTOR - A data network comprises a master, a network distributor and a plurality of network users. The network distributor is connected to a master data path, a first and a second user data path. A method for transferring data telegrams in this data network includes the reception of a first master data telegram sent by the master through the network distributor, the compilation transfer of a first and a second transmission data telegram through the network distributor, and the reception of a first and a second reception data telegram through the network distributor. Further, the network distributor compiles a second master data telegram and transfers it to the master. In this connection, an access indicator of the second master data telegram represents accesses of the network user to the first master data telegram, the first and second transmission data telegrams as well as the first and second reception data telegrams. | 12-17-2015 |
20150365296 | METHOD FOR OPERATING A NETWORK - A method for operating a network that has a network subscriber that is connected to a superordinate bus and to a subordinate bus comprises steps for the reception of a first superordinate data message by the network subscriber via the superordinate bus, the extraction of first data from the first superordinate data message by the network subscriber and for the transmission of a first subordinate data message by the network subscriber via the subordinate bus. In one case, the first subordinate data message comprises the first data. | 12-17-2015 |
