Description
Summary:Purpose This paper sets out to highlight the problem associated with the development of fieldbus diagnostics in a multivendor environment and to propose a solution based on diagnostic function blocks FB. Designmethodologyapproach The work focuses on the masterslave communication model in a PROFIBUS fieldbus system, where three different vendor solutions are investigated. Findings Although the fieldbus standards specify the type and format of the diagnostics data, the extent, location and sequence of diagnostics data within a controller are entirely vendordependent. The outcome from this work defines a framework for representing the diagnostics data in the context of a special function block. Originalityvalue This research work defines a novel unified framework for representing the fieldbus diagnostics data using FB for multivendor solutions in a PROFIBUS environment.
