Abstract :
This paper focuses on dependability modelling and evaluation of fieldbus networks in the presence of permanent faults. Several architectures are analysed, considering different operating modes, topologies and fault types. Two measures of dependability are evaluated: reliability and asymptotic unavailability. The aim is to compare these various design solutions, to define essential parameters and to study their effects on fieldbus dependability
