Simulation of RFieldbus Networks

摘要

Driven by the demand on more flexibility in manufacturing and process automation systems, investigations are made in the field of wireless communication. In the R-FIELDBUS project a new wireless physical layer type was added to an existing fieldbus system. The resulting R-FIELDBUS systems allow adaptive architectures with mixed wired and wireless segments. To be able to analyse the functional and time behaviour of different configurations, a simulation model of the fieldbus system was also extended by the wireless behaviour. This paper describes the used simulation method, the models of the communication protocol as well as the new added wireless medium type as well as providing some first simulation results.
