Abstract (EN):
The WorldFIP protocol is based on a centralised medium access control mechanism,
where a specific station, the bus arbitrator (BA), controls all data transfers between different
stations. At configuration time, the BA is given a list of process variables (the bus arbitrator
table) to scan along with their corresponding periods. In this paper we provide a comprehensive
study on how to configure a WorldFIP bus arbitrator table (BAT), in order to guarantee that
periodic data transfers are performed before their deadlines. The main contributions of this
paper are the provision of both an algorithmic approach for setting the WorldFIP BAT (using
RM and EDF) and a feasibility test to check a priori the timeliness requirements of the periodic
data transfers. Copyright @ 2000 IFAC
