What Happen When Two Can Nodes Are Sending Same Identifier At A Same Time? |
|
Answer» Two nodes on the network are not allowed to SEND messages with the same ID. If two nodes try to send a MESSAGE with the same id at the same time arbitration will not work. Instead, one of the transmitting nodes will DETECT that his message is distorted outside of the arbitration field. The nodes will then use the error handling of CAN, which in this case ultimately will lead to one of the transmitting node being SWITCHED off (bus-off mode).
