This paper shows first that the behaviour of a fieldbus whose terminals can be represented by multi-state components with propagated failures may be described by a set of connected mode automata; the input and output flows of these automata represent either data exchanges or failure propagations. A method to obtain an analytic expression of the reliability of a transmission between two terminals from this model is then proposed.
