Abstract

The goal of this paper is to show the influence of main mechanisms of real time distributed systems on the stability of process control applications implemented through these systems. The first part of the paper shows this influence by analysing the message scheduling (three local area networks are considered : CAN, FIP, ARINC), the message transfer (two protocols are considered : without loss control and with loss control) and the task scheduling (Rate Monotonic (RM) algorithm for independant tasks and RM algorithm (either with priority inheritance or with ceiling priority) for tasks sharing ressources). The second part focuses on the message scheduling in the network CAN (use of a priority scheme) and, by considering a sensor task time triggered and a controller task event triggered, analyses the influence of the choice of the priority scheme.
