Abstract

Industry 4.0 can potentially become the global production language by integrating existing and new technologies to address contemporary manufacturing challenges. Establishing uniform industry standards is central to its successful implementation, necessitating a global effort towards standardization with international cooperation and a systemic perspective. Uniform technical standards are essential for a network connecting diverse factories and companies. Significant progress has been made in standardization efforts, focusing on technologies like the Internet of Things (IoT) and Cyber-Physical Systems (CPS), pivotal to Industry 4.0. One key initiative is the Reference Architecture Model for Industry 4.0 (RAMI 4.0), which employs a three-dimensional coordinate system describing all essential components of Industry 4.0. This system enables the decomposition of complex interrelations into manageable subsystems, clusters, or modules. Another crucial standardization effort is the Industrial Internet Reference Architecture (IIRA), developed by the Industrial Internet Consortium (IIC). IIRA is an open, standards-based architecture designed to manage interoperability, map applicable technologies, and guide technology and standards development. The IIRA framework supports various system types, configurations, and connections across multiple industries and use cases. The rapid growth and evolution of IoT present significant challenges to standardization. However, standardization is crucial for the further development and widespread adoption of IoT technologies, primarily aiming to enhance interoperability among different applications and systems. Efforts ensure that devices and applications from other countries can exchange information seamlessly. Key standards in IoT include communication standards, identification standards, and security standards, which are major drivers for adopting IoT technologies. In this study, comprehensive and uniform standards were reviewed to realize Industry 4.0's strategic vision. Continued international collaboration and a focus on addressing specific standardization challenges were essential to achieve global integration and optimization of manufacturing processes.
