A key element of the energy transition in Germany lies in green hydrogen. The current production of electrolyzers is mostly done in a manufactory-like manner. By digital planning and preparing an assembly with automated, manual and collaborative elements, the manufacturing of water electrolyzers can be scaled economically. In this paper, a reference process from electrolyzer assembly is selected and analyzed for the complete mapping of a data structure. The determined data structure can be used as a basis for a digital twin.

Digitization in engineering promises automated workflows, higher speed and lower costs in the development of automation solutions. The prerequisite for this is not only modularization based on a structured description language, but also uniform, interdependent modeling that ensures automated data exchange across system boundaries. In order to achieve a broad application, the underlying ontology should be based on existing norms and standards and be available in open source applications. However, the collaborative and consistent development of such an ontology requires a structured, methodical procedure and an associated modelling map that serves as an orientation for standardized, work-sharing modelling. A possible approach for the required procedure model and the related map will be presented in this article and validated using AutomationML. The presented approach should point out a possible direction and stimulate further process-controlled modelling efforts of ontologies.
