Resumo(s)
In this paper, we analyse the ability of Profibus fieldbus to cope with
the real-time requirements of a Distributed Computer Control System (DCCS),
where messages associated to discrete events must be made available within a
maximum bound time. Our methodology is based on the knowledge of real-time
traffic characteristics, setting the network parameters in order to cope with
timing requirements. Since non-real-time traffic characteristics are usually
unknown at the design stage, we consider an operational profile where,
constraining non-real-time traffic at the application level, we assure that realtime
requirements are met.
