Abstract:
The advent of Industry 4.0 has brought about the need for seamless communication and integration among diverse industrial automation systems. While current standards such as OPC UA address syntactic interoperability, they fall short in addressing semantic heterogeneity, which poses a challenge to the true understanding of exchanged data. The existing approaches, which rely on textual information models such as the OPC UA companion specifications, suffer from possible ambiguity and difficulties in development and validation. This research aims to overcome these challenges by exploring the development of an explicit, user-friendly, and machine-readable model specification for the conditional implementation of Rockwell Automation drives’ motion axis attributes within OPC UA. The paper delves into suitable formalisms for model specification, taking into account user interaction and expressivity, and proposes mechanisms for model validation and future extensions. These efforts pave the wa
y for enhanced semantic interoperability in industrial automation, thus contributing to the advancement of Industry 4.0.
