Abstract

Modern distributed industrial control systems need improvements in their dependability. In this paper we study the dependability of a fault tolerant distributed industrial control system designed in our university. This system is based on fault tolerant nodes interconnected by two communication networks. This paper begins showing the architecture of a single node in the distributed system. Reliability and safety results for this node are presented using a theoretical model based on Stochastic Activity Networks (SAN). Based on this architecture, the theoretical model of the distributed system is then presented; in order to evaluate the reliability and safety of the whole system models based on stochastic activity networks are used, and the results obtained using UltraSAN are presented.
