IIoT is assisting manufacturing industries to maintain productivity growth, remain competitive in the market, and enhance safety with advanced technologies.
FREMONT, CA: The manufacturing industry is witnessing enormous advancements due to the integration of Industrial Internet of Things (IIOT) technologies. The sector has always prioritised increasing productivity over improving safety. Although factory assets have often been isolated within closed industrial control systems or supervisory control and data acquisition (SCADA) systems, sufficient data to support those higher productivity goals can still be challenging to obtain.

However, with the introduction of IIoT, there was a drastic transformation in the industries. IIoT consists of a flexible concept that imbibes technologies including sensing, networking, and communications and combines them with analytics and computing. This helps in building strong connections between the factory's operational technology (OT) systems and the enterprise information technology (IT) sector. IIoT will be a significant factor for companies to achieve digital transformation and a major cause for the fourth revolution. It gathers all the key elements together to capture and analyse manufacturing data, distinguishing IIoT from the conventional ways of doing the process.
Technologies offered by IIoT
Sensors and Wireless Networking Technologies
Smart, digital sensors help to monitor almost any parameter in an industrial environment or process, such as motor speed, vibration, inspection data, etc. They are affordable to deploy in large numbers. Wireless networking technologies have point-to-point and mesh networking that enables connecting huge numbers of sensors with fewer additional cabled connections, which might be disruptive to install and potentially unreliable.
IIoT-Friendly Communication and IC Technology
IIoT-friendly communication protocols like open platform communication unified architecture (OPC UA) are platform-independent and enhance internet standards such as TCP/IP and HTTP (S) that promote machine-to-machine communication harmoniously. Additionally, low-power IC technologies and energy harvesting and storage enable deployment in any environment.
High-Performance Computing and Data Science Advancements
Access to high-performance computing in the cloud and its move toward the edge is affordable even for small businesses on an "as-a-service" basis (including AI, which is well suited to pattern recognition tasks that are critical to analysing sensor data). The increase in computing performance to amass and analyse enormous amounts of data (Big Data) has led to advancements in data science. This helps in understanding unidentified causes and consequences that are present in every process taking place inside the factory.
Benefits of IIoT
Effective IIoT programmes enable manufacturing companies to monitor equipment and process performance constantly in a detailed manner. Data from real-time and the past can be obtained and analysed. The sensed data can be augmented by data from other sources from across the business, the wider supply chain, and the outside world. Then, analytical applications combine these data sets and observe patterns among the huge number of variables, which would be impractical to analyse using conventional techniques.
Moreover, this data can be used to enhance the performance of processes in operations on the factory floor. It functions by acquiring vast numbers of machine parameters, settings, adjustments, and environmental data such as temperature and humidity. This process can be combined with other types of data, such as the operator’s ID. The result of the analysis can be applied to find opportunities, solve problems, and improve the efficiency of manufacturing performance.
