    A Controller Area Network ( CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but it can also be used in many other contexts.

  2. The Controller Area Network (CAN bus) is the nervous system, enabling communication. In turn, 'nodes' or 'electronic control units' (ECUs) are like parts of the body, interconnected via the CAN bus. Information sensed by one part can be shared with another.

  3. Sep 21, 2022 · A controller area network (CAN) bus is a high-integrity serial bus system for networking intelligent devices. CAN busses and devices are common components in automotive and industrial systems. Using a CAN interface device, you can write LabVIEW applications to communicate with a CAN network.

    • CAN is used for ECU communication in cars. Image used courtesy of the Infosec Institute. Onboard diagnostics (OBD) is your vehicle's diagnostic and reporting system that allows you or a technician to troubleshoot problems via diagnostic trouble codes (DTCs).
    • PLC connected to a DeviceNet network that uses CAN for the data link and physical layer. CAN Message Frames. So what does a CAN message actually look like?
    • Standard CAN message frame. The first bit is the start of frame (SOF). This dominant bit represents the start of a CAN message. Next is the 11-bit identifier, which establishes the priority of the CAN message.
    • Extended CAN message frame. CAN Message Types. Now that you know what a CAN message looks like, you might be wondering what kinds of messages are passed along the bus.
  4. Jan 29, 2023 · The CAN bus is a serial communication bus, designed for robust performance within harsh environments, primarily in industrial and automotive applications. It is basically a vehicle bus standard that allows microcontrollers and devices to communicate with each other. CAN bus is one of the protocols used in On-Board Diagnostics (OBD).

  5. Nov 27, 2020 · CAN bus (Controller Area Network) is a central networking system that connects different Electronic Control Units (ECU), other devices in a vehicle. Modern cars can have 100 ECUs So CAN bus communication becomes very important.
