Phase 3: Data and Service Integration
In this phase, the focus lies on the creation of new applications across factory sites, especially for asset monitoring and data analytics. For security and safety reasons, communication between assets in different factories is indirect via a Factory Digital Image. A role based access control applies to all data and services.
Data and Service Integration will feature a cockpit application for the Smart Factory Web. It will provide functions to combine, visualize and aggregate factory data. Key issues such as information overload and computation scalability with real-time constraints will be addressed through innovative IIoT and architectural approaches based on on-going research work.
Services will be implemented for plant monitoring, as well as material and information logistics.
Analogously to Plug & Work above, the industrial standards OPC UA and AutomationML are used in combination. This then creates the basis for data communication with the asset over OPC UA and across the Smart Factory Web.

The asset and factory models in AutomationML can be used to automatically generate matching visualizations in the same hierarchy as that of the factory structure. OPC UA is used to transfer process variables and other asset data. This method can be applied at SFW or factory level.
