What are edge devices in the context of Industry 4.0?

In the context of Industry 4.0, edge devices refer to sensors and machines that produce data. These devices are integral to the Industrial Internet of Things (IIoT), functioning at the "edge" of the network where data is generated. They work by collecting real-time data from their environments, which can include temperature sensors, pressure gauges, and various types of machinery that monitor operational parameters.

The primary role of edge devices is to facilitate immediate data processing and analysis close to the source of data generation. This localized processing reduces latency and bandwidth usage because it minimizes the need to send large volumes of raw data to central servers or cloud systems for analysis. By processing data at the edge, businesses can respond more quickly to operational changes, enhance efficiency, and improve decision-making.

While central servers, cloud storage systems, and analytics processing units are vital components of an Industry 4.0 ecosystem, they do not fit the definition of edge devices, as they are typically involved in centralized data processing, storage, and advanced analytics rather than immediate data collection.
