Guaranteeing DCCS Timeliness Requirements Using P-NET Fieldbus Networks
Ref: HURRAY-TR-9818 Publication Date: 1, Nov, 1998Abstract:
In this paper, we analyse the ability of the P-NET [CEN, 96a] fieldbus network to cope with the timeliness requirements of a Distributed Computer Control System (DCCS), where messages associated to discrete events should be made available to a distributed application within a maximum bound time. The major contribution of this paper is the integration of a pre-run-time schedulability analysis of the P-NET protocol with the typical Distributed Computer Controlled System requirements. A case study of a petrochemical DCCS application and its message communication support is presented, stressing some of the timing requirements that must be satisfied by the message exchanges. An implementation supported by a P-NET fieldbus network is then analysed and some conclusions are drawn about this example.
