A Study of DeviceNet Technology for the Low Quantity Vehicle Industry 2001-01-0064

The popularity of CAN (Controller Area Network) in the production vehicles is well established. As a result, CAN has been developed for use in many non-automotive applications. This gave rise to the development of an open higher layer CAN protocol known as DeviceNet. With the popularity of DeviceNet for Automation Systems, this technology has drastically decreased in cost. Although DeviceNet is quite complex to develop, it easier to implement than SAE J1939 due to the large number of commercial off-the-shelf product that is available. Also, there are many configuration and diagnostic tools available by the same means. There are more than 300 vendors of DeviceNet product.
Researchers at the University of Warwick have built a vehicle demonstrator using CAN/DeviceNet modules. This paper will illustrate the ease of vehicle system integration utilising this popular technology. Some of benefits highlighted will be:
  • Drastic reductions of installation times
  • Highly sophisticated, but simple, means of end-of-line testing
  • A radical improvement of diagnostics
  • Significant reduction of turnaround times for build changes for customer specifications.
This paper focuses on the low quantity-build vehicle industries, e.g. agricultural machinery, buses, construction vehicles, military vehicles, sanitation vehicles, etc. Also a brief cost analysis of the system will be reviewed.
