Validation of industrial automation systems is the process of verifying that commissioner specifications are successfully implemented.

Abstract
Validation of industrial automation systems is the process of verifying that commissioner specifications are successfully implemented. To this aim, formal approaches are needed when the considered system is critical. In view of this, in this paper a model-based approach is proposed. It exploits the compactness and graphical representation of Interpreted Petri nets, extended with time, to model system specifications. In particular, the key idea of the system validation approach is to compare the observed behaviour of the system with the expected behaviour, obtained by updating on-line the model of system specification by means of a state-estimation algorithm.
