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： A subscriber node of a communication system, a communication system and a method for transmitting a message in the communication system. The message is transmitted from a first subscriber node of the communication system via a data bus of the communication system to a second subscriber node of the communication system. An application program of the first subscriber node files the message, that is to be sent, in a message memory, from where it is retrieved by a communication controller, upon a sending command of the application program, and is transmitted via the data bus. In particular in the case of a cancellation of the transmission job, in order to be able to improve the capacity utilization and the efficiency of a host CPU, it is provided that a transmission event for the message, that is to be sent or that has been sent, is stored in at least one transmission event memory, that is functionally separate from the message memory, and that the application program is able to access the data stored in the event memory at any time.

摘要： In a method for storing messages in a communications module, the messages to be stored contain first data having a first data volume and second data having a second data volume, and it is possible for the second data volume to be different per message. A message memory contains a header segment, in which the first data of the message are stored in a respective header area per message, and the message memory also contains a data segment, in which the second data of the message are stored in a respective data area per message The message memory is configured such that a division between the header segment and the data segment is variable, depending on the number of messages and the second data volume.

摘要： A method and a filter system for filtering messages which are received, via a serial data bus of a communications network, in a communication module of a user connected to the data bus. To allow particularly simple and efficient filtering of incoming messages, even when there is a large number of filtering criteria, it is proposed that the filter system includes a list in which multiple identifier pairs are stored which define a range delimited in each case by a first identifier and a second identifier. The identifier for an incoming message is compared at least to selected identifier pairs from the list, and a query is made concerning whether the identifier for the incoming message is greater than, or greater than or equal to, the selected first identifier, and is less than, or less than or equal to, the selected second identifier. The incoming message is forwarded to the application or rejected, depending on the configuration bit specification, if the identifier for the incoming message is within the range delimited by the first identifier and the second identifier.
