MULTI-MASTER PROFIBUS DP MODELLING AND WORST CASE ANALYSIS-BASED EVALUATION

Multi-master Profibus Dp Modelling and Worst Case Analysis-based Evaluation

This paper provides an analysis of the real-time behaviour of the multimaster Profibus DP network. The analysis is based on the evaluation of the worstcase message response time and the results obtained are compared with those present in literature, pointing out its capability to perform a more accurate evaluation of the performance of the Profibus network.

Evaluating Worst Case Response Time in Mono and Multi-master Profibus Dp

Profibus networks are often used as the communication infrastructure for supporting distributed computer-controlled applications. Very often these applications impose strict real-time requirements. A widely used class of Profibus networks is the Profibus-DP profile, which may be implemented as mono or multi-master network. The aim of this paper is to analyse the real-time behaviour of both mono...

Designing Real-time Systems Based on Mono-master Profibus-dp Networks

Profibus networks are widely used as the communication infrastructure for supporting distributed computer-controlled applications. Most of the times, these applications impose strict real-time requirements. Profibus-DP has gradually become the preferred Profibus application profile. It is usually implemented as a mono-master Profibus network, and is optimised for speed and efficiency. The aim o...

An Efficient Simulator for the Profibus-dp Mac Layer Protocol

The main goal of this paper is to develop an integrated general-purpose simulator for the Profibus MAC layer protocol in order to evaluate the steady-state behavior of this protocol, under a variety of possible operational conditions in a faulty communication channel. This protocol is part of the Profibus-DP system used widely as a standard and popular industrial communication system. This work...
