Web31 jan. 2024 · Tree topology combines the characteristics of bus topology and star topology. This topology divides the network in to multiple levels/layers of network in which all the computers are connected with each other in hierarchical fashion. The top-most node in tree topology is known as a root node, and all other nodes are the descendants of the root ... WebThe arbitration ID determines the priority of the messages on the bus. If multiple nodes try to transmit a mess age onto the CAN bus at the same time, the node with the highest priority (low est arbitration ID) automatically gets bus access. Nodes with a lower priority must wait until the bus becomes available before trying to transmit again.
