An IEC 62061 compliant safety system design method for machinery

Ljungquist, Bengt LU and Thelin, Thomas LU (2005) In Lecture Notes in Computer Science 3688. p.330-343
Abstract
The purpose of safety systems is to reduce dangers to human life or environment to acceptable levels. In order to aid companies in this when developing safety systems for functional safety of machinery, the standard IEC 62061 has recently been released. The standard proposes an outlined design method to follow requirements specification. However, companies that use the standard have to implement a design method on their own. This paper presents an implementation and enhancements to the design method in terms of using state machines and function block analysis documentation. The state machine connects the functional safety requirements with ordinary behaviour for equipment under control. The proposed method is evaluated in an industrial... (More)
The purpose of safety systems is to reduce dangers to human life or environment to acceptable levels.

The standard proposes an outlined design method to follow requirements specification. However, companies that use the standard have to implement a design method on their own. This paper presents an implementation and enhancements to the design method in terms of using state machines and function block analysis documentation. The state machine connects the functional safety requirements with ordinary behaviour for equipment under control. The proposed method is evaluated in an industrial case and the main results from this indicate that the method works well, but needs tool support. Hence, the paper presents requirements for such a tool and discusses how it could be used to develop safety systems. (Less)
