Modelling of Safety Fieldbus System via SW Tool SHARPE

Abstract

Paper deals with the modelling of the safety-related Fieldbus communication system, which has to guaranty Safety Integrity Level (SIL) according to standard IEC 61508. There are methods of safety analysis for the closed safety Fieldbus transmission system summarized. The mainly part the modeling SW tool SHARPE describes. The realized models are based on Fault Tree Analysis (FTA) and Markov analysis.
