Profisafe and Profibus for High Availability and Safety in the Process Industries

Process fieldbuses and open fieldbus safety protocols have caught the attention of process users in recent years thanks to the potential to cut costs and improve diagnostics.  Separate the facts from the hype in this ARC white paper: Profisafe and Profibus for High Availability and Safety in the Process Industries.

Executive Summary Excerpt

Process fieldbuses and open fieldbus safety protocols have caught the attention of process users in recent years thanks to the potential to cut costs and improve diagnostics. Modern fieldbuses have helped to unify network architectures and created a high level of data transparency from which applications such as Plant Asset Management and Manufacturing Execution Systems profit tremendously. At the same time, process safety solutions have evolved from being a cost burden and “necessary evil” to a strategy for improving productivity by increasing system availability.

Profibus International, an industrial consortium of automation suppliers, has mated safety with industrial networking to create solutions for “built-in” safety based on all available media. End-users are now taking advantage of these technologies to unify their network architectures and eliminate the need for a second, parallel bus while achieving safety integrity levels up to SIL3. Benefits of networked safety include shortened start-up times, lower wiring costs, better diagnostics and, in the long-term, faster and more efficient maintenance.
