The mechatronic systems design requires a collaborative and coordinated work of multidisciplinary teams. These teams need business tools but also centralized and consistent information between all stakeholders. PLM systems are theoretically capable of proposing a system able to manage all data from different field. However, the current integration of a mechatronic system is made in an empirical and partial way. In fact, the integration does not take into account either the implicit links between businesses, or the whole product life cycle. The object of this paper is to present a global approach of mechatronic systems integration in a PLM using a specific modeling. This modeling is based on the definition of a meta-model to characterize the links and life cycles. These elements are modeled in an engineering system approach with SysML to allow their integration in a PLM system.
