Information Modeling of Cyber-Physical Systems using OPC-UA

Achieving interoperability is a great challenge in the area of Cyber-Physical Systems (CPSs) because of the specificities of these systems, which are complex distributed systems, mostly in the form of systems of systems that are an intersection of information and operational technologies with emergent behavior, acting in different time scales, with different granularities and accuracies, interacting with the operating environment. The main purpose of the research is to propose an information model for the development of service-oriented CPSs using OPC UA and generate sub-models for the Asset Administrative Shell (ASS). CPSs are multi-layered, service-oriented, and agent-based systems that enable the grouping of system elements at levels, reduce connections between modules, facilitate abstractions, and allocate responsibilities. The proposed approach is illustrated by an example of improving the interoperability of a pilot batch reactor.
