CAN bus

A Controller Area Network (CAN bus) is a robust 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 can also be used in many other contexts.

CAN Bus Wiring Diagram, a Basics Tutorial. The CAN bus is a common digital network used in automotive, industrial, medical and scientific systems for routing sensor data between pieces of equipment. The main advantages are high resilience to noise, reliability, low cost, simple wiring and ease of use.

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.

Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications. The CAN bus is primarily used in embedded systems, and as its name implies, is a network technology that provides fast communication among microcontrollers ...

CAN-Bus Data Cable reduces wiring, electronic interference, and offers high-speed network communication. It is resistant to abrasions and cuts, while also has an excellent resistance to oil and chemicals. CAN-Bus cable from Waytek is RoHS compliant.

In short, the Controller Area Network (CAN) ... Messages are broadcast in a system that requires very little physical wiring making CAN bus low cost, robust and efficient.

there are no open circuits in CAN_H or CAN_L wiring; your bus system has two terminating resistors (one at each end) and that they are 120 O each. 1.2 CAN_H/CAN_L Voltage Each node contains a CAN transceiver that outputs differential signals. When the network communication is idle the CAN_H and CAN_L voltages are approximately 2.5 volts.

This article introduced the Controller Area Network or CAN. CAN is a robust serial communication bus found mostly in automotive and industrial environments. CAN uses a differential signal, which makes it more resistant to noise, along with a priority arbitration scheme for non-destructive message transmission.

CAN Bus Description. The Controller Area Network (CAN) specification defines the Data Link Layer, ISO 11898 defines the Physical Layer. The CAN bus [CANbus] is a Balanced (differential) 2-wire interface running over either a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or Ribbon cable. Each node uses a Male 9-pin D connector.

All nodes on the CAN network receive the CAN frame, and, depending on the arbitration ID of that transmitted frame, each CAN node on the network decides whether to accept the frame. If multiple nodes try to transmit a message onto the CAN bus at the same time, the node with the highest priority (lowest arbitration ID) automatically gets bus access.
