Abstract
How to support real-time traffic of important aperiodic messages using Foundation Fieldbus (FF) is investigated in this paper. An integrated worst-case response time (WCRT) analysis of aperiodic message indicates FF can´t effectively guarantee real-time traffic of important aperiodic message despite FF providing such mechanisms as PT (Pass Token) priority and PT rotation period, etc. After finding the cause of current mechanism´ deficiency, an improved mechanism proposed and validated with simulation in this paper. Further, some conclusions such as ongoing work are provided in this paper.
