Resumo(s)
Modern factories are complex systems where
advances in networking and information technologies are
opening new ways towards higher efficiency. Such move
is being driven by market rules with ever-increasing
competition levels, in search for faster time-to-market,
improved process yield, non-stop operations, flexible
manufacturing and tighter supply-chain coupling. All
these aims present a common requirement, i.e. a realtime
flow of information, from the plant-floor up to the
management, maintenance, suppliers and clients, to
support accurate monitoring and control of the factory.
This stresses the importance achieved by the communication
infrastructure in modern manufacturing industry.
This paper presents the authors view concerning the
current trends in modern factory communication systems.
It addresses the problems of seamlessly integrating
different information flows with diverse requirements,
mainly in terms of timeliness. In this aspect, the debate
between event-triggered and time-triggered communication
is revisited as well as the joint support for both types
of traffic. Finally, a view of where factory communication
systems are moving to is also presented, showing the
impact of open and widely available technologies.
