Table 2: Industrial Internet Levels of Interoperability
The IIRA functionally decomposes a typical Industrial Internet system into five major Functional
Domains, as shown in Figure 3. Briefly,
1. The Control Domain comprises a collection of functions performed by the industrial assets
or controls systems involving sensing, control and actuation in the familiar ‘closed-loop
control.’
2. The Operations Domain comprises a collection of functions that are required to keep the
industrial assets up and running efficiently. They include the typical maintenance
functions with added intelligent capabilities such as predictive maintenance, etc.
3. The Information Domain comprises a collection of functions for collecting and managing
data gathered from the industrial assets and for performing analytics on the data to gain
insight into the operational states of these assets.
4. The Application Domain comprises a collection of functions specialized for specific usage
scenarios that apply the analytic insights from the Information Domain to achieve specific
business objectives such as optimizing the operations of a large fleet of assets.
5. The Business Domain comprises supportive business functions such as enterprise
resource management (ERP), manufacturing execution system (MES), etc. needed to
realize end-to-end Industrial Internet operations.
