Commitment We are and will remain the world's leading organization in the field of digital networking for industrial and process automation, serving our customers, our members and the press with the best solutions , benefits and information. We are committed to setting and protecting the standards for open communication and control in the automation and process market. Introduction From the outset, the field of automation has been subject to continuous change. Not so long ago, this change was limited to the production area of a company. In production , the implementation of fieldbus technology has meant considerable innovation, enabling the migration from centralized to decentralized automation systems. This has been the PROFIBUS objective for more than 10 years. In those 10 years PROFIBUS has become the world market leader in fieldbus technology. In spite of the outstanding success of recent years, PROFIBUS development continues with undiminished enthusiasm and energy. Initially the focus was on communication technology. Current activities center around system integration, engineering and, in particular, the application profiles. These profiles have made PROFIBUS the only fieldbus that provides comprehensive both factory and process automation. Additionally, Information Technology (IT) increasingly determines development in today´s world of automation. Modern fieldbus systems have adopted IT principles and are achieving greater consistency with the corporate management level. In this respect, industrial automation is following the development trends of the office world, where IT has long since left its mark, radically transforming infrastructure , systems and processes. The integration of information technology in the world of automation opens up many new prospects for global data communication between automation systems. In pursuit of this objective, PROFIBUS is enhanced by the Ethernet-based communication standard PROFInet. The use of open standards rather than proprietary solutions ensures long-term compatibility and ex-pandability-in other words-protection of existing investment. This is a matter of key importance to the PROFIBUS User Organization. The continuous development of PRO-FIBUS technology provides members with a long-term perspective .

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...
متن کاملFrom Task Scheduling in Single Processor Environments to Message Scheduling in a PROFIBUS Fieldbus Network
In this paper we survey the most relevant results for the priority-based schedulability analysis of real-time tasks, both for the fixed and dynamic priority assignment schemes. We give emphasis to the worst-case response time analysis in non-preemptive contexts, which is fundamental for the communication schedulability analysis. We define an architecture to support priority-based scheduling of ...
متن کاملEvaluating 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...
متن کاملLegacy to Industry 4.0: A Profibus Sniffer
Legacy industrial communication protocols are proved robust and functional. During the last decades, the industry has invented completely new or advanced versions of the legacy communication solutions. However, even with the high adoption rate of these new solutions, still the majority industry applications run on legacy, mostly fieldbus related technologies. Profibus is one of those technologi...
متن کاملMulti-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.
