Abstract
A bus system, a method for operating a bus system and a participant of a bus system are provided. The participant includes a timer and a transceiver circuit. The transceiver circuit is configured to receive a data packet having a time stamp value via a bus. The timer is configured for synchronization, based on the time stamp value. The timer is configured to change the time stamp value. The transceiver circuit is configured to transmit the data packet with the changed time stamp value via the bus.
Claims14
A participant of a bus system comprising:
- a timer;
- a transceiver circuit configured to receive a data packet having a time stamp value via a bus;
- wherein the timer is configured for synchronization, based on the time stamp value,
- wherein the timer is configured to change the time stamp value to a changed time stamp value,
- wherein the transceiver circuit is configured to transmit the same data packet with the changed time stamp value via the bus,
- wherein the data packet includes data symbols each having a fixed number of bits, wherein a plurality of the data symbols comprise the time stamp value of the data packet, and wherein the transceiver circuit is configured to receive and to transmit the data packet data symbol by data symbol such that a transmission of one of the data symbols of the data packet and a receipt of a subsequent one of the data symbols of the data packet takes place simultaneously, and
- wherein the transceiver circuit is configured to change a data symbol of the time stamp value that is received first and has a least significant bit of the time stamp value and transmit the data symbol having the least significant bit to a subsequent participant before receiving a data symbol of the time stamp value having a most significant bit of the time stamp value.
4 more elements
A method for operating a bus system, the method comprising:
- providing a first participant;
- providing a second participant;
- receiving and transmitting a data packet by the first participant;
- synchronizing a timer of the first participant based on a time stamp value received in the data packet;
- changing the time stamp value to a changed time stamp value by the first participant;
- and
- transmitting the changed time stamp value by the first participant to the second participant via the same data packet,
- wherein the bus system has a first interface device, the first participant being removable from the bus system by detaching the first participant from the first interface device, and
- wherein the first interface device includes a first switching device which effectuates a bypass to the second participant so that the data packet is receivable not by the first participant but rather by the second participant with an unchanged time stamp value if the first participant is removed.
6 more elements
A bus system comprising:
- a first participant configured as a first slave;
- a second participant configured as a second slave;
- a master;
- a bus;
- and
- a first interface device, wherein the first slave is removable from the bus system by detaching the first slave from the first interface device,
- wherein the master and the first slave and the second slave are connected via the bus to transmit a data packet such that the data packet transmitted by the master passes through the first slave and the second slave in a fixed sequence,
- wherein the master is configured to transmit a time stamp value in the data packet,
- wherein the first slave is configured to receive the data packet with the time stamp value,
- wherein the first slave is configured to synchronize a timer of the first slave based on the time stamp value,
- wherein the first slave is configured to change the time stamp value to a changed time stamp value and to transmit the changed time stamp value to the second slave in the data packet,
- wherein the second slave is configured to receive the data packet with the changed time stamp value and to synchronize a timer of the second slave based on the changed time stamp value, and
- wherein the first interface device includes a first switching device which effectuates a bypass to the second slave so that the data packet is receivable not by the first slave but rather by the second slave with an unchanged time stamp value if the first slave is removed.
