Towards Holistic Interoperability of Cyber-Physical Production Systems within RAMI 4.0

Abstract

The growing prominence of Industry 4.0 necessitates the increased utilization and complexity of Cyber-Physical Production Systems (CPPS). However, challenges persist in the systematic application of the RAMI 4.0 reference architecture for CPPS and the lack of standardization. To address these issues, we propose a novel process-based methodology leveraging RAMI 4.0 for analyzing, evaluating, and enhancing system interoperability within CPPS. By examining two exemplary CPPS in this study, we demonstrate the significance of minimizing interfaces and adaptations. The results reveal a reduction in required hardware, interfaces, information, and protocols between the systems. Our findings contribute to the advancement of standardized approaches for achieving holistic interoperability among individual systems within the RAMI 4.0 framework.
