Enhancing Interoperability of Digital Twins Based on Digital Twins Definition Language

Abstract

The Industry 4.0 is featured by a continuously-evolving digital transformation, aiming to automate all the traditional industrial practices. Digital Twin is one of the most important solutions to reach this aim. Among the standards currently available to realize Digital Twins there is the Digital Twins Definition Language. Digital Twin requires exchange of data with the real system it models and with other applications which use the digital replica of the system. In the context of Industry 4.0, a reference standard for an interoperable exchange of information between applications, is Open Platform Communications Unified Architecture. The idea behind the paper is to exploit this standard to allow a Digital Twin based on Digital Twins Definition Language to exchange data with any applications compliant to the Open Platform Communications Unified Architecture. A proposal about the mapping from Digital Twins Definition Language to Open Platform Communications Unified Architecture will be presented and discussed in this paper.
