Advantages of CAN bus

The CAN bus standard is widely accepted and used in nearly all vehicles and many machines. This is mainly due to the following key benefits:

 

 

Simple and low-cost: ECUs communicate over a single CAN system rather than directly through complex analog signal lines, reducing errors, weight, wiring and cost. CAN chipsets are readily available and affordable.

 

 

Fully Centralized: The CAN bus provides a single entry point for communication with all networked ECUs - enabling central diagnostics, data logging and configuration.

 

 

Extremely robust: The system is robust to electrical and electromagnetic interference - ideal for safety-critical applications (e.g. vehicles)

 

 

Efficient: CAN frames are prioritized by ID number. The highest priority data can access the bus immediately without interrupting other frames.

 

 

Reduce vehicle weight: By eliminating kilometers of heavy insulated wires and their weight on the vehicle.

 

 

Easy deployment: Proven standards with a rich support ecosystem.

 

 

EMI resistant: This makes CAN ideally suited for critical applications in vehicles.

 

 

CAN has excellent control and fault detection capabilities. It's easy to detect errors so the transmitted data gets where it needs to go.

 

 

It is an ideal protocol when distributed control of complex systems is required. It reduces heavy wiring, thereby reducing cost and weight. The cost of the chip is low, and implementing CAN is relatively easy due to the simplicity of the protocol design.

 

 

Another advantage of using CAN is that the first two layers: the physical layer and the data link layer are implemented in inexpensive microchips, available in a variety of configurations.

 

 

CAN adapters allow to connect a PC to CAN networks in industrial automation or automotive monitoring applications. The access is given by USB 2.0, TCP/IP or PCI bus.

The role of DeviceNet terminal resistor

DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
