DESIGNING A CAN BASED ATM FIELDBUS

Abstract

The Controller Area Network (CAN) bus was initially introduced for automotive applications, but due to its low cost, high speed and high reliability, it has also become a standard in industrial distributed real-time control applications. Asynchronous Transfer Mode (ATM) is a high speed network technology that aims to combine all types of communication, that is, data, voice, and image in a single network structure. Various studies have been carried to incorporate existing network types such as Ethernet and Token Ring with ATM. It is also important to cover the FieldBus communication in this concept. This study aims to incorporate ATM technology with the FieldBus communication. In this concept, CAN based ATM bus structure is introduced. This structure also introduces an opportunity to connect FieldBus networks with ATM seamlessly. Simulation studies have been carried out to validate the introduced model and the results showed that it is feasible to implement the system
