Number of CAN Nodes

The maximum number of nodes depends on the electrical characteristics of the nodes on the network.

High-Speed/Flexible Data-Rate CAN

If all nodes meet the ISO 11898 requirements, you can connect at least 30 nodes to the bus. You can connect higher numbers of nodes if the nodes’ electrical characteristics do not degrade signal quality below ISO 11898 signal level specifications.

The TRC-8543 electrical characteristics allow at least 110 CAN ports on a network.

Low-Speed/Fault-Tolerant CAN

If all of the nodes meet the requirements of Low-Speed/Fault-Tolerant CAN, up to 32 nodes may be connected to the bus.
