Therefore, their analysis becomes an important aspect to be considered, particularly in situations where communications have real-time constrains and the network operates on faulty environments. In this paper the behavior of PROFIBUS network in the pres-ence of faults is analyzed. This analysis is performed in an expe-rimental base supported by a real network. The network opera-tion is disturbed through a set of fault injection experiments from which performance metrics related with PROFIBUS out-age times are evaluated.engconference object
