Similarly, human-machine interfaces make human-robot collaboration easier.

Finally, we come to the Internet of Things. This technology provides channels of communication that transport data from machines to other machines, and from customers to business owners. Manufacturing IoT fuels the other digital technologies, from big data and advanced analytics to artificial intelligence. It enables truly data-driven decision-making in manufacturing.

Read on to find more about the role of IoT in manufacturing, its chief benefits, and applications Discover what companies are currently leveraging IoT and some future scenarios involving IoT in manufacturing.

Smart manufacturing and IoT

The Internet of Things, a term coined in 1999 by Kevin Ashton, refers to the collection of small yet powerful devices that can connect to the Internet and exchange data with other devices and people. The nodes in the IoT networks gather data from their environment either with the help of sensors or by communicating with other devices that have access to the target data. The data is communicated with Cloud services via Internet connectivity.

Data from IoT devices is augmented by other information and stored in the Cloud, where it is used to extract useful insights and improve business processes in any industry.

IoT is an integral part of the smart manufacturing concept. Smart manufacturing is characterized by a high level of adaptability and rapid design changes that are only possible with fully connected factories and supply chains. IoT solutions in manufacturing enable fast changes in production levels based on demand, efficient production, better material use, and optimization of the flow of goods and materials into and out of manufacturing environments. IoT solutions for manufacturing often hide behind terms such as industrial IoT, cyber-physical systems, industry 4.0, and smart factories.

IoT benefits for manufacturing

People operating robotic arms with devices

Interconnected and ubiquitous IoT devices are transforming many aspects of the manufacturing industry. The clearest benefits are cost reduction, better product quality, mass customization, improved safety, and increased process efficiency.

Cost reduction

IoT devices provide highly insightful information about the utilization of assets. This in turn leads to better asset management. Making sure assets are used optimally decreases the costs associated with their maintenance. One of the basic principles in management is that everything that can be measured can be managed. IoT technology is a powerful ally in this respect. IoT devices help factories and offices to optimize their energy use and reduce operational costs. At the same time, IoT is opening up new avenues for revenue generation by allowing companies to shift from product-based business models towards service-based ones.

Better product quality

The main objective of any process improvement initiative in manufacturing is to increase the quality of the product while decreasing the cost of production. Improvements in the quality of products can, unsurprisingly, have a profound impact on a manufacturing business. High-quality products can reduce waste, generate other products that are even better, increase customer satisfaction, and improve sales.

IoT plays a crucial role in increasing product quality. This is down to the fact that the most common reasons for deteriorated product quality are machine malfunction and the poor calibration/setup of the machine. Both of these phenomena are reflected in measurable machine signals such as temperature, vibration, and noise. Connected IoT devices can monitor these signals, and detect and report any anomaly or deviation from ideal working conditions. This close, consistent observation of machinery ensures that the desired product quality is achieved.

Mass customization

Mass customization, mass personalization or made-to-order are all terms used to describe situations when a mass-produced product is customized to fit customer demands. Studies have shown that more than 50% of customers are interested in acquiring personalized or custom products. Mass customization is a great economic driver for companies that are seeking to diversify their revenue streams.

The biggest barrier to mass customization is the cost. Current manufacturing systems are made for mass production. When, in contrast, a product is produced under a predetermined break-even quantity, the production becomes unprofitable. IoT is transforming manufacturing facilities into more flexible units that can routinely and profitably deal with customization. Traditionally, production had to be stopped to reprogram some parts of the production track so that it could handle the production of different lines. With the help of IoT, new settings and programs are applied automatically via the network. As a result, many different products can be manufactured at the same time without the need for stoppages. IoT solutions for manufacturing are turning a mass production system into a game of mass customization.

Improved safety

IoT improves workplace safety in many different respects. In manufacturing and other production facilities, workers are equipped with RFID tags that can be embedded in their clothes to monitor their location. Meanwhile, wearable devices collect data about their vital signs such as skin temperature, heart rate, and perspiration. Location and biological data collected from workers is sent to the Cloud where it is analyzed together with other data coming from their work environments such as noise, ambient temperature and humidity, air quality, motion, and light. Additional data about work planning and weather can be combined with this to detect any anomalies in the workers’ behavior. IoT in the manufacturing environment ensures a safer workspace by preventing high-risk activities that lead to injuries. Similarly, it addresses safety problems in hazardous environments. For example, IoT sensors are capable of detecting any gas leakages or steam outbursts.

By monitoring employee activity, IoT technology can be used as a preventive measure to warn against prolonged physical inactivity. Equally, it can ventilate workspaces to improve air quality.

Increased process efficiency

IoT supplies the necessary information for a better decision-making process. In manufacturing, IoT gathers crucial data about the performance of items of machinery on the factory floor and provides insightful information about equipment (mal)functioning. By using this data, managers and field technicians can follow necessary procedures to enhance the efficiency of the plant.

For many organizations, the manufacturing process is not monolithic. It is often distributed across multiple facilities. Thanks to its ubiquitous connectivity, IoT offers monitoring capabilities that enable companies to oversee the whole manufacturing operation in a unified manner, irrespective of the physical locations of the plants.

IoT applications in manufacturing

IoT has numerous applications in manufacturing. Some of the most prominent of these are predictive maintenance, remote monitoring and control, asset tracking and management, digital twins, and connected operational intelligence.

Predictive maintenance

Maintenance of manufacturing equipment has traditionally been done in two ways: reactive or preventive. Reactive maintenance was carried out after the equipment had become defective. Preventive maintenance was done on a schedule based on the normal operating conditions or historical data provided by the manufacturer of the equipment. Both of these methods are potentially inaccurate: there is the risk that equipment will be over-maintained or, conversely, under-maintained. Predictive maintenance, however, mitigates the shortcomings of reactive and preventive maintenance by enabling just-in-time maintenance that leads to optimal utilization of equipment and lower maintenance costs.

Predictive maintenance makes use of IoT to collect data about the machine’s health and how it is used, while artificial intelligence algorithms analyze this data to predict when the equipment will fail given current operating conditions. Manufacturing equipment is monitored by connected sensors that send data to the Cloud where it is analyzed in order to detect anomalies and predict how much useful life remains. IoT in manufacturing enables more efficient maintenance operations and management of the equipment.

Remote monitoring and control

Remote monitoring and control have been possible in manufacturing since the 1990s via supervisory control and data acquisition (SCADA) systems. SCADA systems were built with large, stationary manufacturing facilities in mind. To make SCADA more agile and flexible in moving data to the remote servers, OPC-UA was introduced. OPC-UA, developed by OPC Foundation, is marketed as a machine-to-machine communication protocol for industrial automation. Nevertheless, many manufacturing companies still struggle with maintenance and lack of opportunities for expanding the SCADA and OPC-UA combination. As customers expect more and more efficient services, companies are seeking ways to stay agile, flexible, and cost-effective through the use of cloud-based remote monitoring and control solutions.

The Internet of Things in manufacturing offers many benefits over classic SCADA and OPC-UA systems. IoT increases the overall equipment effectiveness (OEE). This productivity model combines downtime, production rate, and quality. Thanks to connected sensors and cloud-based data analytics, achieving the desired OEE is more cost-effective and simpler to realize than ever before. IoT also makes the relevant information easily accessible to all employees involved in the overall efficiency of the manufacturing operation, such as line operators, maintenance crews, and production supervisors.

Asset tracking and management

Asset tracking or, more generally, asset management, is a process of tracking physical assets in the facility or throughout the supply chain to prevent their loss and to maintain their desired condition. Traditionally, asset management was performed manually by scanning barcodes and doing inventories. IoT allows for the streamlining of this process, and automates it. IoT asset tracking provides tools to bring about significant efficiency improvements.

An asset management system usually consists of a tiny and connected tracking device that is attached to the asset, or placed next to it. It proceeds to send data about the asset location and condition to the Cloud. IoT-based asset management solutions also provide a management platform from which the tracking devices are coordinated and where data analysis is performed.

The main business benefits of IoT-based asset management are increased efficiency due to automated and precise management, real-time information about the asset conditions in time-sensitive applications, automation of management and interconnection with supply chain systems, and recoverability of stolen or lost assets.

Digital twins

The cornerstones of Industry 4.0 and cyber-physical systems — digital twins — are the digital representations of real objects. They use the same data as real-world objects and produce results identical to those of a real-world object under the same conditions. This mimicking of behavior allows for extensive investigation of real-world objects in a simulated environment.

The twin and the real-world counterpart both receive data from the same sensors. In this way, the twins can simulate the physical objects in real-time and offer deep insights into their performance and possible malfunctioning.

In manufacturing, digital twins benefit from the acquisition, aggregation, and analysis of data from IoT devices. They open a way to the simulation of possible scenarios for predicting results in the virtual world without affecting real-world production. Thus digital twins save precious time and help predict problems before they occur in the physical process. Overall, digital twins increase process efficiency and product quality.

Connected operational intelligence

Operational Intelligence (OI) is real-time business analytics that provides insights into data and business operations. Connected OI, on the other hand, utilizes industrial IoT sensors to generate the data feeds from core business assets. In manufacturing, connected OI relies on the connected sensors that upload data to the Cloud, where it is analyzed to deliver results as operational instructions. Thanks to the IoT devices, connected OI allows enterprises to make decisions and act through predefined automated actions.
