Abstract

Functional safety is involved in many machines, processes, and systems to mitigate risks by reducing the likelihood of the occurrence or the severity of the consequences of a hazard. The development of functional safety systems realising safety functions is typically directed by laws and standards, which set requirements on the development process and design of the system. In addition, functional safety systems often operate in a context, in which other control entities also affect the operation of the system under control. In this article, nine patterns considering the design and development functional safety systems, in terms of their architecture and co-operation with other controlling entities, are presented. The purpose of the patterns is to support the designers of functional safety systems to cope with the mentioned aspects.

Keywords

Acknowledgments

The patterns presented in this article have originally been published in [41] and [24], and a grant to reuse the content has been kindly provided by VikingPLoP 2012 and 2013 organizers. The publications were written in co-operation with Timo Vepsäläinen and Seppo Kuikka.

The authors would like to thank the people who have helped us with these patterns. The authors would like to thank VikingPLoP 2012 members: Veli-Pekka Eloranta, Ville Reijonen, Dirk Schnelle-Walka, and Joonas Salo and especially our shepherd Farah Lakhani for their valuable feedback in the VikingPLoP 2012.

In addition, with no less importance, the authors would like to thank the workshop group members in the VikingPLoP 2013: Samuel Lehtinen, Christopher Preschern, Johannes Koskinen, Pekka Alho, Marko Leppänen, Stefan Radomski, Ville Reijonen, and Veli-Pekka Eloranta and especially our shepherd Dirk Schnelle-Walka for their valuable feedback and input to improve the patterns and the paper.
