Abstract: The integration of resource communication in the development of industrial installations has become one of the most treated problems in the industrial area. This requires a high management and control of communication system for the transfer of complex information. For wide distances, the dynamical control of the resource communication becomes more exacting. It must ensure the quality of service necessary for real-time applications, media synchronization and security of information. Designing such applications requires specific tools and formalisms for exact specification and graphical representation allowing to perform simulations for analysis, verification and validation of the design results before the implementation stages. The paper deals with such problem where, using a colored Petri net (CPN) formalism, it is possible to perform specification of the project including the integration of resource communication. An approach using CPN models is proposed to formalize the constraints in the communication systems while intensive simulation allow to investigate the dynamic behavior and to solve some problems related to synchronization and quality of service. A real industrial example of a distance drive of robot via Internet is treated to illustrate the method.
