This paper addresses the problem of online identification of discrete event systems (DES). The approach held is a passive one: an interpreted Petri net (IPN) model is built from the measuring of the DES output evolution. First, several behavioral properties of DES are introduced, then an algorithm that computes IPN models from cyclic output streams is presented. In an online operation the currently obtained model represents the observed behavior of the system and successively computed models lead asymptotically to the actual one.
