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. Since this event, PROFIsafe has evolved to become the leading and most comprehensive safety communication technology in the world. PROFIsafe is approved by both the IFA and TÜV. PROFIsafe is also an International Standard( IEC 61784-3-3) since 2007. This document provides a thorough insight into the PROFIsafe technology and the related topics.
Safety has gained a constantly growing importance in the consciousness of the population worldwide. PROFIsafe is the safety solution technology for PROFIBUS and PROFINET. It is a software solution, which enables it to cover the whole gamut of automation requirements.
PROFIsafe is a supplementary technology for standard PROFIBUS and PROFINET. It is the purpose of this PROFIBUS guideline to collect agreed upon requirements and constraints for the design of PROFIsafe devices and for PROFIsafe specific operations within a normal industrial environment as defined in IEC 61000-6-2.
