Modeling Best Practices

The OPC Foundation released a Whitepaper describing best practices for information modelling. It includes naming conventions and other helpful tips:

Unified Automation offers ressources for its UAModeler, which are applicable to modeling in general.

(paper) A systematic approach to OPC UA information model design


Excerpt from the abstract: This paper describes a systematic approach to OPC Unified Architecture (OPC UA) information model for representing the static and dynamic behavior of manufacturing systems. Moreover, the approach is generic in the sense that it can be used to define information models for multiple target technologies, such as OPC UA, MTConnect and others. It even allows to reuse large parts of the generated models for similar manufacturing utilities and various target technologies. Therefore, we first present a concept for system analysis and design by using the Unified Modeling Language (UML), which is widely accepted for interdisciplinary work. The information gathered is then transformed to OPC UA information models which serves as target technology in this paper. The purpose of this approach is to simplify the process of defining virtual representations of manufacturing systems. Applying the presented concept allows transformation of classic manufacturing systems into CPPS with SOA-based communication and semantically rich virtual representations of individual components.
