Abstract
The main goal is to propose submodels consisting of safety list of properties (SLOPs) of safety instrumented functions (SIF) in alignment with IEC 61511.
The SLOP included in this new submodel can then be aligned with and integrated into the IEC CDD. The submodel template will build on the work of two ongoing initiatives: 1) results from the Norwegian joint industry project named Automated process for follow-up of safety instrumented systems (APOS 2.0), including an UML model developed with basis in requirements and definitions in IEC 61511. 2) Results from the NAMUR WG1.3 on Information Management and Tool who is developing a similar UML model. Alignment activities have been carried out between NAMUR and the APOS 2.0 project, and we would like to involve persons from both organizations in preparing the details of the proposed new submodel templates.
Although this specific proposal pertains particularly to establishing thesubmodel for safety instrumented function (SIF), we recognize the need for expanding our scope to establish a set of relevant submodels under the domain of ‘functional safety for process industries’, for example:
-Submodel for safety instrumented system (SIS) components
– Submodel for SIS subsystems
– Submodel for Safety requirement specification (SRS)
– Submodel for data collection in SIF operation.
