Graphical Programming Languages for Functional Safety

Summary: This work presents the current state of research into the development of recommendations for the application of graphic full variability programming languages in safety-related system developments.The basis for the development presents an analysis of existing safety-related standards to understand the way of implementation in text-based programming environments and fulfill applicable requirements.Based on the fundamental standard analysis, a list of different methods and procedures has been created. Their implementation in a graphical full variability programming language meets all requirements following the standards.Therefore, the core of this work essentially provides the development and validation of the recommendations for graphical programming languages to meet applicable standards and guidelines. The result of this development will be architecture and recommendations for programming guidelines.Finally, the received recommendations for a particular graphical programming language shall be used to provide practical proof of feasibility. Recommendations are applied to the concrete development environment LabVIEW with the programming language G. Implementation and validation in an evaluation project and verification through unique methods from the standards have been planned.
