Abstract(s)
The problem of providing a hybrid wired/wireless communications for factory
automation systems is still an open issue, notwithstanding the fact that already there are
some solutions. This paper describes the role of simulation tools on the validation and
performance analysis of two wireless extensions for the PROFIBUS protocol. In one of
them, the Intermediate Systems, which connect wired and wireless network segments,
operate as repeaters. In the other one the Intermediate Systems operate as bridge. We also
describe how the analytical analysis proposed for these kinds of networks can be used for
the setting of some network parameters and for the guaranteeing real-time behaviour of
the system. Additionally, we also compare the bridge-based solution simulation results
with the analytical results.
