Abstract
This paper focuses on the application of a controlled process for W7-X to develop and implement the Safety Instrumented System (SIS) based on the international safety standard IEC 61511 for the process industry sector. The organization and the approach of the whole life cycle of the SIS are described. The definition of a risk graph and its calibration according to the W7-X-specifics were necessary to assess the required rating of availability and reliability as safety integrity levels according to the standard. The fixed verification and validation process is a prerequisite for the acceptance by the authority as well as the correct and complete documentation of the process and the test certificates.
