One of the major events within the lifetime of the PROFIBUS and PROFINET International (PI) community was the first release of a specification for safety communication in 1999. It caused a quantum leap in possibilities in the world of automation. Since this event, PROFIsafe has evolved to become the leading and most comprehensive safety communication technology in the world. PROFIsafe is now progressing toward becoming an International Standard within IEC 61784-3-3. It is the objective of this document to provide a thorough insight into the PROFIsafe technology and the related issues without becoming too engulfed in specific details. It is not meant to replace standards or the official specifications and guidelines mentioned below. Those are definitive and binding.
PROFIsafe is approved by both the IFA and TÜV.
