CAN (Controller Area Network) is a communication protocol used widely in vehicles, process control and other areas of industry. It is fault tolerant and deterministic which is why it is used widely for safety-critical systems.

The VM2 can connect to a CAN Bus with the addition of a small, simple and inexpensive CAN bus driver IC.

Tests have shown that the VM2 can concurrently send and receive up to 15,000 CAN messages per second. Processing of received messages will reduce this throughput, depending on the level of processing required.
