CAN bus - Wikipedia
A CAN network can be configured to work with two different message (or frame) formats: the standard or base frame format (described in CAN 2.0 A and CAN 2.0 B), and the extended frame format (described only by CAN 2.0 B).

What is a CAN frame? As per the data link layer, communication over the CAN bus is done via CAN frames. Below is a standard CAN data frame with 11 bits identifier (CAN 2.0A), which is the type used in most cars. The extended 29-bit identifier frame (CAN 2.0B) is …
Standard CAN frame format | Extended CAN frame structure
This page compares standard CAN frame format vs extended CAN frame format and mentions various fields used in standard CAN frame format and extended CAN frame structures.

Feb 21, 2024 · CAN protocol supports two different types of data frames which are distinguished from the size of bits used in arbitration field value. In the base frame format, the CAN bus uses an 11-bit identifier which supports up to 2 11 nodes with a unique identifier.
A controller area network (CAN) is ideally suited to the many high-level industrial protocols embracing CAN and ISO-11898:2003 as their physical layer. Its cost, performance, and upgradeability provide for tremendous flexibility in system design.
Controller Area Network (CAN Bus) Tutorial - Message Frame Format
Jun 16, 2021 · Per definition, a CAN data or remote frame has the following components: SOF (Start of Frame) - Marks the beginning of data and remote Frames. Arbitration Field – Includes the message ID and RTR (Remote Transmission Request) bit, which distinguishes data and remote frames. Control Field – Used to determine data size and message ID length.
CAN (Controller Area Network) protocol - Javatpoint
The node can be a sensor, microcontroller, or a gateway that allows the computer to communicate over the network through the USB cable or ethernet port. The CAN is a message-based protocol, which means that message carries the message identifier, and based on the identifier, priority is decided.

Jan 19, 2021 · A message transmitted on the CAN network is also known as a frame. There are four types of CAN frames: Data frame – This is the most common type of frame, and the only one that contains actual data.
There are four types of CAN messages, or “frames:” Data Frame, Remote Frame, Error Frame and Overload Frame. The data frame is the standard CAN message, broadcasting data from the transmitter to
