Patent number: 7564845Abstract: The method carrying out permanent redundant transmission of data messages in disjunctive paths, such that circulating data messages can be reliably identified and destroyed. The method includes splitting a redundant message into two data messages in the respective branching point in a transparent manner. The method further includes causing no additional load for the receiver of the two identical messages by, for instance, allocating a current cycle number to the received data message in a cyclic communication system (26). This can also be ensured in a non-cyclic communication system by means of software processing, for instance, by processing the header identifier of the data messages. In particular, the behavior of the communication system (26) with respect to “learning” the addresses in the individual users (1, 2, 3, 4, 5), more particularly the switches, is not altered for the remaining non-redundant data traffic.Type: GrantFiled: March 18, 2005Date of Patent: July 21, 2009Assignee: Siemens AktiengesellschaftInventors: Dieter Brueckner, Dieter Klotz, Karl-Heinz Krause

Patent number: 7539215Abstract: A subscriber in a communication system (102) for transmitting and receiving data telegrams, wherein a data telegram includes reference data or user data and an identifier. The control of transmitting and receiving data telegrams is based on check data sets (122). A check data set includes an address for the reference data or user data and the identifier of the data telegram, which is assigned to the check data set. A transmission list (120) includes a first number of check data sets. A circuit unit (128) generates, based on a check data set of the transmission list, a data telegram to be transmitted. In addition, a second number (136, 138) of check data sets is provided. An assignment unit (140, 144) assigns a received data telegram to one of the check data sets of the second number of check data sets, wherein the assignment is carried out based on the identifier for the received data telegram.Type: GrantFiled: April 16, 2004Date of Patent: May 26, 2009Assignee: Siemens AGInventors: Dieter Brueckner, Dieter Klotz, Karl-Heinz Krause

Publication number: 20090055564Abstract: The invention relates to a method for data transmission in a serial bus system comprising a control unit and bus users. The method comprises steps: receiving a first data telegram by a bus user from the control unit, wherein the data telegram has a data field containing output data; reading out the data field intended for the bus user from the first data telegram; preparing input data as a response to the read out data field; checking whether a predefined criterion is met, wherein if the criterion is met a second data telegram is newly generated and the input data is attached to the second data telegram and if the criterion is not met, the input data is attached to a data telegram previously received from another bus user; and transmitting the input data to the control unit by the second data telegram.Type: ApplicationFiled: August 21, 2008Publication date: February 26, 2009Inventors: Dieter Klotz, Albert Tretter

Publication number: 20060018327Abstract: A method for the transmission of data messages in a switched cyclical communication system (38, 39) with a linear or ring arrangement of the users. Real-time critical data messages are transmitted in a first segment (20) of a transmission cycle (31), without the need to first plan the send and receive instants in the forwarding users, such that the chronological start (21) of the first segment (20) of a transmission cycle (31) is guaranteed by all users in all transmission cycles through monitoring. The duration of the first segment (20) of a transmission cycle (31) can be fixedly specified or automatically adjusted using a timeout procedure.Type: ApplicationFiled: March 21, 2005Publication date: January 26, 2006Inventors: Dieter Brueckner, Dieter Klotz, Karl-Heinz Krause, Karl Weber
