摘要:
A method for evaluating signal data includes a bus signal channel supplying the signal data, a reference channel supplying reference signal values, which form the basis of the signal data, and a computer performing a signal interpretation based on an interpretable portion of the signal data and on the reference signal values, and reconstructing a signal based on the interpretation.

A wireline communication system and method are provided that utilize a military standard 1553 bus to transmit both military standard 1553 communication signals and other communication signals, such as those transmitted in accordance with another communications protocol. A wireline communication system may include a military standard 1553 bus and a military standard 1553 node configured to communicate with military standard 1553 communication signals at a first predefined range of frequencies. The wireline communication system further includes a first interface node configured to communicate via the military standard 1553 bus with second communication signals having a second predefined range of frequencies, different than the first predefined range of frequencies. The second communication signals are transmitted along the military standard 1553 bus at less than a predetermined decibel level. The second predefined range of frequencies and the predetermined decibel level are selected to limit interference between the different signals.

A central device includes an information replacing unit. When the information replacing unit detects, on the basis of contact information acquired from an electric coupler provided in a coupled vehicle in a formation B having a train-information management device that manages vehicle information in accordance with the Ethernet® protocol, that a formation A that includes a train-information management device that manages vehicle information in accordance with the ARCNET protocol is coupled to the formation B, then the information replacing unit replaces vehicle information from the formation A with vehicle information in accordance with the Ethernet® protocol; outputs the replaced vehicle information to the formation B; replaces the vehicle information from the formation B with the vehicle information in accordance with the ARCNET protocol; and outputs the replaced vehicle information to the formation A.

The disclosure relates to a field bus network having two masters and at least one slave which are connected to one another in a dual ring comprising a first ring and a second ring and each of the two masters being configured for generator data packets and sending out a generated data packet on each of the rings at regular time intervals. The at least one slave being configured for receiving a data packet at an input and forwarding it at an output. Each of the two masters being configured for receiving a data packet coming from the other master in each case at an input and forwarding it at an output.

The invention relates to an EtherCAT fieldbus system, a master and a slave for the system and a method. The slave is configured to be coupled to the EtherCAT fieldbus. A first configurable memory of the slave stores a first activation list indicating for consecutive bytes of data of an EtherCAT datagram a corresponding fieldbus memory management information or synchronization management information.
摘要:
Generally, a means for coupling widely differing fieldbus or network systems to their own respective safety mechanisms is provided, in such a way as to ensure the transmission of safety data between at least two bus/network systems with different safety mechanisms.A method and an apparatus are provided for coupling at least two (field)bus/network systems to respectively different safety mechanisms, in particular respective proprietary safety mechanisms, with safety data which is to be transmitted between the different system-based safety mechanisms being processed additionally using a safe data structure which is defined but is system-independent.
摘要:
In a method for safe transmission of data of a field device of process automation technology via a fieldbus, the transmission signal is registered as a check signal in the field device during the transmission. Analysis of the check signal, on the basis of data content or signal form, detects whether the desired data were transmitted properly.
摘要:
A vehicle communication network (200) includes a plurality of network elements (202-212) and a plurality of communication links (214-230) communicatively coupling the network elements in a point-to-point configuration. At least a portion of the plurality of communication links are specified in accordance with a shared-access bus protocol. The plurality of communication links are arranged to communicate data packets between the network elements, and data packets are modified for transport via the plurality of communication links.
