摘要： A time-division multiplex method for serial data transmission includes executing a first priority resolution for messages to be transmitted by a plurality of stations on a communications channel and which are assigned to a first prefix, and transmitting a first data frame by a first station of the multiplicity of stations, wherein the first station transmits a first message with the first prefix and with the highest priority, during a predefined first access slot. The method also includes executing a second priority resolution for messages to be transmitted on the communications channel and which are assigned to a second prefix, and then transmitting of a second data frame by a second station of the plurality of stations, where the second station transmits a second message with the second prefix and with the highest priority of the second priority resolution, during a predefined second access slot.

摘要： In a method for serial communication of data frames between nodes connected by a bus system, the transmitter and receiver roles are assigned to the nodes for each data frame by the arbitration procedure defined in the CAN-Standard ISO 11898-1. The exchanged data frames, which include multiple bits, have a logical structure according to the CAN-Standard ISO 11898-1, including a Start-Of-Frame-Bit, an Arbitration Field, a Control Field, a Data Field, a CRC Field, an Acknowledge Field and an End-Of-Frame Field. Each bit has a bit time which is divided into Time Segments. In response to a predefined value of a specific bit within the Control Field a first node of a first node group restarts its protocol decoding state machine and waits until it has synchronized itself to the bus activity and a second node of a second node group communicates using CAN FD Specification protocol.

摘要： A controller area network (CAN) node comprises an internal high differential bus line (CANH) and an internal low differential bus line (CANL). The CAN node further comprises a receiver (RXD) comparator coupled to both the internal CANH and the internal CANL that outputs an internal RXD signal. The CAN node further comprises an RXD dominant time out (DTO) circuit. The RXD DTO circuit includes: a) an RXD dominant transition detector coupled to an output of the RXD comparator; b) a timer triggered by the RXD dominant transition detector detecting a dominant RXD transition; c) an RXD dominant timer comparator that is coupled to an output of the timer which compares an output of the timer to a selected value; d) an internal RXD dominant signal is changed to an RXD DTO recessive signal after a selected time interval has lapsed and can include a fault output to signal this fault condition.

摘要： Messages on controller area network (CAN) buses are communicated over subsea links. Repeaters couple CAN buses to each end of a subsea link. The subsea link may be, for example, a twisted pair or a single wire with a sea ground. The repeater detects a direction of transmission, that is, whether a signal began on the CAN bus coupled to the repeater or on the subsea link coupled to the repeater. Signals from the CAN bus are conditionally transmitted to the subsea link depending on the detected direction of transmission. Signals from the subsea link are conditionally transmitted to the CAN bus depending on the detected direction of transmission. The repeater can operate at the physical layer without analyzing contents of the CAN bus communications.

摘要： In order to provide a communication apparatus that can reduce the delay in transmission of communication messages even when the bus load is heavy, a data transmission module is connected to a communication bus, over which communication messages are transferred, in such a manner that the data transmission module can transmit/receive the communication messages to/from the communication bus. A bus monitoring unit included in the data transmission module detects, for a given time period, the timings at which communication messages are flowing over the communication bus, and acquires the detection results as usage status data of said time period. The data transmission module further includes: a usage status predicting unit that predicts, on the basis of the acquired usage status data of the detection time period, an idle timing at which no communication messages are flowing over the communication bus; and a data transmitting unit that transmits communication messages to the communication bus at the predicted idle timing.

摘要： A method is described for checking the correct functioning of a serial data transmission in a bus system having at least two bus users. The bus users are connected to the bus via a bus connection unit and exchange messages via the bus. The sending access to the bus for each message is granted to a bus user via the arbitration process according to CAN standard ISO 11898-1, this bus user becoming the sender for this message. The messages have a logic structure according to the CAN standard, i.e., are composed of a start of frame bit, arbitration field, control field, data field, CRC field, acknowledge field, and end of frame field. The correct functioning of the data transmission is checked during the transmission by comparing a transmission signal, sent to the bus connection unit, to the reception signal (CAN_RX) received by the bus connection unit. The method is characterized in that a transmission signal (CAN_TX_DEL), which is delayed by a delay time (T_DELAY) compared to the transmission signal (CAN_TX), is held in the sender, and the undelayed transmission signal (CAN_TX) or the delayed transmission signal (CAN_TX_DEL) is used for checking the correct functioning of the data transmission, as a function of a switchover.
摘要翻译：描述了一种用于在具有至少两个总线用户的总线系统中检查串行数据传输的正确功能的方法。总线用户通过总线连接单元连接到总线，并通过总线交换消息。通过根据CAN标准ISO 11898-1的仲裁过程向总线用户授予每个消息的总线发送访问权，该总线用户成为该消息的发送者。这些消息具有根据CAN标准的逻辑结构，即由帧比特，仲裁字段，控制字段，数据字段，CRC字段，确认字段和帧场结束组成。通过将发送到总线连接单元的发送信号与由总线连接单元接收的接收信号（CAN_RX）进行比较，在发送期间检查数据传输的正确功能。该方法的特征在于，与发送信号（CAN_TX）相比延迟了延迟时间（T_DELAY）的发送信号（CAN_TX_DEL）被保存在发送器中，并且未延迟发送信号（CAN_TX）或延迟发送信号（CAN_TX_DEL）用于检查数据传输的正确功能，作为切换的功能。
