RESUMO

Intemational and national research institutions and companies have focused efforts to develop and promote the implementation of the international standard ISO 11783, based upon the digital communication protocol CAN (Controller Area Network), in order to integrate devices in machines and agricultural implements. Therefore, it is presented the development and the application of a model based on Petri netsformalism as a tool for the support, analysis and accomplishment of a CAN bus in time-critical applications. The model was constructed in an environrnent for edition and sirnulation of colored Petri nets, the software DesignCPN. The sirnulation was used for the analysis of the behavior and the performance the CAN bus for several configurations, which will be embedded in an Autonomous Agricultural Vehicle (VAA).
