4. Develop and Test Models

This system configuration implements the layered Model+View testing architecture for the drilling example.

• The HMI,MODEL and VIEW devices encapsulate the functionality of the corresponding layers of the architecture.
• As in the DRILL_VIEWL configuration, the VIEW device contains two instances of the specialized VIEW_PANEL resource type to provide the necessary layout of View elements for the drilling example.
• The MODEL device contains the Model elements (instances of the XBAR_MDLL, SOL_MDLL, and XSLIDE_MDLL types) and the logic for their interactions.
• Inter-layer communication is implemented with the local multicast pattern. In particular, transfer of workpieces among physical elements is modeled by appropriate instances of the LOADL type interacting with local subscribers encapsulated in the element models.
