ABSTRACT
This chapter describes the definition of a semantic meta-model meant to describe the functional characteristics of a Cyber Physical Systems (CPS), which are relevant from its design and simulation for its integration and coordination in an industrial production environment. CPS are engineered systems that offer close interaction between cyber and physical components. Engineering information is stored following the Object-Oriented Paradigm, and physical and logical plant components are modelled as data objects encapsulating different aspects. Property is an abstract class derived by Identified Element and represents runtime properties of every resource and prototype. An important feature that the CPS data model should support is the possibility to create links between runtime properties and properties defined inside assets and between properties defined by two different assets. A prototype is a Resource model that is complete from a digital point of view, but it is still not applied in any plant model.
