Frequently Asked Questions

What is can and how does it work?

As stated earlier, CAN is a peer-to-peer network. This means that there is no master that controls when individual nodes have access to read and write data on the CAN bus. When a CAN node is ready to transmit data, it checks to see if the bus is busy and then simply writes a CAN frame onto the network.

What is high-speed can?

High-speed CAN is by far the most common physical layer. High-speed CAN networks are implemented with two wires and allow communication at transfer rates up to 1 Mbit/s. Other names for high-speed CAN include CAN C and ISO 11898-2. Typical high-speed CAN devices include antilock brake systems, engine control modules, and emissions systems.

What is a CAN frame?

CAN devices send data across the CAN network in packets called frames. A CAN frame consists of the following sections. CAN Frame -- an entire CAN transmission: arbitration ID, data bytes, acknowledge bit, and so on. Frames also are referred to as messages.

What is the standard CAN frame format?

The standard CAN frame format. SOF (start-of-frame) bit – indicates the beginning of a message with a dominant (logic 0) bit. Arbitration ID – identifies the message and indicates the message's priority. Frames come in two formats -- standard, which uses an 11-bit arbitration ID, and extended, which uses a 29-bit arbitration ID.
