What is IIoT and How Does IIoT Work?

The term Industrial Internet of Things (IIoT) refers to the application of Internet of Things (IoT) technology in industrial settings. It involves the interconnection and communication between physical devices (such as industrial sensors and industrial actuators), machinery, and systems used in various industries, enabling the collection, analysis, and exchange of data to optimize industrial processes, increase efficiency, and improve decision-making.
At its core, IIoT operates through a network of interconnected devices, and machines that communicate with each other and transmit data, but retrieving the information from these in industrial environments is not always easy or possible. Many IIoT companies do not provide full connectivity for true IIoT to take place. Industrial facilities are characterized as being harsh in terms of communication. Noise, vibration, rotation, humidity, heat, and more contribute to this being a very challenging task. This is where IO-Link Wireless comes in. By enabling real-time industrial cable-grade communication, it allows getting this information from the different components and machines, factory-wide, thus empowering IIoT and making it a reality.
The IIoT implementation process includes the deployment of sensors and other IIoT devices across industrial environments. These devices collect data related to various parameters, such as temperature, pressure, humidity, vibration, and more, depending on the specific use case. The collected data is then transmitted from the IO-Link Wireless Device to the IO-Link Wireless Master, and from there to the PLC via OPC UA and other Industrial Ethernet protocols (such as Ethernet/IP, PROFINET, or EtherCAT), and via MQTT or OPC UA to cloud-based and On-premise applications, where it is stored and analyzed. The configuration of the IO-Link Wireless system and the MQTT publishing is done via a designated IO-Link Wireless Software. As many machines use sensors and components manufactured by various vendors, it’s critical for the data-collecting ability to be vendor agnostic, as in the case of IO-Link Wireless.
In the cloud, advanced analytics and machine learning algorithms are employed to process and interpret the collected data. These algorithms can identify patterns, detect anomalies, and generate actionable insights. The analyzed data is then presented to stakeholders in a meaningful way, often through dashboards or reports, enabling them to make data-driven decisions and optimize operations. Additional Machine Optimization Platforms may be integrated into the system to ensure process efficiency is maximized.
Advanced IIoT systems also leverage edge computing, where some data processing occurs at the device or Gateway level itself. This approach reduces latency and allows for faster decision-making in time-critical applications. Edge computing is particularly useful in situations where a rapid response is required, such as in manufacturing processes or predictive maintenance scenarios.
