Abstract

Wireless networks are beginning to be employed in industrial automation systems as extensions of field networks (fieldbuses), in order to link devices which may not be equipped with a wired connection. In this way, all the benefits deriving from the use of a fieldbus may be maintained. This paper investigates a wireless extension of Profibus DP, one of the most popular fieldbus standards, based on the Bluetooth radio interface. After a description of how the data link layer services of Bluetooth could be used to implement the Profibus DP functions, we present a theoretical network performance analysis. The results obtained are then validated by means of numerical simulations.
