Flexible Manufacturing Systems through Integration of Asset Administration Shell and OPC UA with PLC
No full textThe increasing demand for flexible and interoperable manufacturing systems necessitates the integration of digital technologies to enable real-time adaptability and data exchange. This research presents a methodology leveraging Asset Administration Shell (AAS) as a central enabler for smart manufacturing. By transitioning from static (Type 1) to reactive (Type 2) AAS and outlining a pathway to proactive (Type 3) AAS, key challenges in creating flexible systems are addressed. A system architecture integrating AAS with OPC Unified Architecture (OPC UA) and Programmable Logic Controllers (PLCs) is developed, enabling real-time synchronization. This modular framework aligns with Industry 4.0 principles, supporting scalable and adaptive manufacturing solutions
Representing Property Dependencies within AutomationML Based Digital Twins
No full textModel-based systems engineering (MBSE) is gaining importance within the design of production systems. MBSE is exploited to start and support engineering-chain-crossing consistent and lossless engineering data transport and use finally resulting in a consistent information model that represent sets of digital twins for all relevant assets. Therefore, MBSE strongly depends on the modelling capabilities of the applied model rep-resentation technologies. One of these technologies currently under investigation is AutomationML. AutomationML has been proven to be efficient for information exchange and integration but has insufficient capabilities to represent dependencies be-tween asset properties. This paper introduces an Excel inspired dependency modelling approach for AutomationML based dig-ital twins, to take a step towards closing this gap
