The control domain denotes the functions taking place in edge devices that serve as industrial controls. These functions include reading data from sensors in the devices, applying rules and logic to create fine-grained closed-loop processing, and providing control over the physical system through actuators. The devices might be networked together or highly distributed and are most often distant from a centralized data store containing historical data gathered from the devices. In the Industrial Internet, they are connected via a network connection back to this central data gathering point.
The following diagram pictures devices in the field (in manufacturing plants, distribution centers, or on transit vehicles in our supply chain example), cloud-based data processing components, and business on-line transaction processing (OLTP) systems and tools. The typical...
