The IIoT becomes reality: the transformation to smart factories for environmental sustainability and operational competitiveness is on its way - powered by semiconductor solutions that are the key to smart, safe and sustainable manufacturing processes. It is expected that the smart factory market will grow at a compound annual growth rate (CAGR) of 9.6 percent to reach around 244.8 billion U.S. dollars by 2024.*
Industry has seen a tectonic shift in both consumer and B2B customer demands and increasing manufacturing and production complexity. By using the power of big data and digital technologies companies can overcome these challenges to achieve greater productivity and growth, to meet their sustainability commitments, and to ultimately become more competitive. Therefore, it is essential to collect, understand and use these massive amount of data created in the Industrial Internet of Things (IIoT). For this new world of manufacturing processes in the context of Industry 4.0 it is a prerequisite to have a scalable industrial IoT stack that’s going to be able to handle that data – secured and efficient.
The goal is to create autonomous production in which people, machines, systems and products communicate with each other independently. This is intended to make manufacturing processes more flexible, scalable and efficient. The result are intelligent value chains and product life cycles that begin with development, continue through manufacturing, assembly, product delivery and maintenance, and finally end with recycling.

The benefits of a smart factory are obvious: maximizing performance, ensuring high quality, reducing the risk of human error, providing data for analysis and optimization purposes, minimizing downtime and disruptions through predictive maintenance.
For a factory to become smart, the following requirements must be met:
Disruptive technologies have significantly changed our lifestyle in the past few decades. Robots are joining the ranks of innovative and disruptive technologies by revolutionizing traditional habits and processes. Today’s robots can identify and navigate through surroundings, work alongside and even interact with humans. Moreover, they teach themselves the skills required to complete a new task.
According to ABI Research, shipments are expected to grow at a CAGR of 4.5% in 2030 compared to 2020 - for cobots, the expectations are as high as 43%!

The future of industrial automation is brimming with new opportunities to develop superior processes and deliver better products to customers.
In the last two years, we've seen everything from a rush on hygiene products and food due to lockdown announcements to a significant shortage of semiconductor chips. The chip shortage has led to a bottleneck in production - from automakers to consumer electronics developers, everyone is feeling the pinch. Rising demand, supply chain issues and raw material shortages have led more and more manufacturers to consider ways to optimize their manufacturing processes.
This hype in the field of industrial automation is being fueled by other trends mostly triggered by digitalization and increasing networking:
The orientation to the trends poses major challenges for many industrial companies.

Machines and systems generate huge amounts of data in today's factories. To make this data usable in a way that enables automated processes in manufacturing, it must be processed with a very short delay time. This is made possible by edge computing. At the same time, the greatest possible data sovereignty must be ensured so that sensitive customer or production data does not leave the company's own cloud.
Cloud computing has established itself as an integral part of Industry 4.0 in production companies. However, computing power outsourced in the cloud sometimes results in long transfer times. Industrial plants equipped with sensors for realtime requirements, for example, would have to send the current status data to the cloud again and again, which would slow down the required responses accordingly.
This is where edge computing helps
With this technology, data processing takes place close to where it is needed, at the "edge" of the network. In other words, data is not stored and processed in a remote cloud, but where it is generated: in the device itself or from a local computer, server or mini-data center. Collection, analysis and further processing can then take place at the local nodes. The acceleration of data streams data processing can take place in near real time. Ideally, edge and cloud computing go hand in hand for best results.
A strong connection: Edge Artificial Intelligence
Edge AI is an emerging field and growing fast. Edge AI can combine the power of the cloud with the benefits of local operation to improve the performance of AI algorithms over time. The original paradigm of simply moving all of the data generated on the edge to the cloud for analysis and machine learning has run into three fundamental barriers, namely privacy, reliability and latency. Running these algorithms efficiently on edge eliminates these barriers and allows AIoT products to scale much more rapidly. Powerful semiconductor solutions from Infineon create the framework for IIoT at the edge:
Predictive maintenance offers the potential to optimize maintenance tasks in real time over system lifetime, maximizing the useful life of equipment while still avoiding disruption to operations.
At present, many companies are already using solutions for predictive maintenance, whereby data from machinery is continuously evaluated and compared with past samples. This enables impending malfunctions to be detected before they actually occur. Thanks to the availability of modular IoT sensors and ready-to-use software solutions provided e.g. at ModusToolbox™ for essentials such as machine learning and cloud connectivity, quick implementation without requiring significant up-skilling in data science and AI, a modular condition-monitoring solution is possible and can deliver powerful results that demonstrate the value of IIoT applications.
Leveraging the power of the smart factory
Infineon’s broad range of XENSIV™ sensors can be deployed to monitor everything from single components of production machinery to an entire smart building ecosystem.

Far more data is collected in smart factories than industrial control systems have previously had to process. At the same time, the number of potential applications for industrial control systems has grown alongside Industry 4.0. Yet space costs money—including in factories—which is why the growing number of control systems has been accompanied by demand for smaller system sizes. In turn, this requires flexible electronic components that still need to be sufficiently robust for industrial applications. Microcontrollers are at the heart of every control system, no matter how large or small. Every microcontroller devised for industrial applications must feature real-time performance and advanced connectivity that supports multiple communication protocols. A higher degree of integration minimizes the need for external components and ensures a more reliable solution.
At present, many companies are already using solutions for predictive maintenance, whereby data from machinery is continuously evaluated and compared with past samples. This enables impending malfunctions to be detected before they actually occur. The BASF facility in Ludwigshafen is a good example, where the company has developed an early-warning system that enables it to plan maintenance on production plants, pumps, motors, and heat exchangers more effectively. This analyzes real-time and historic data, enabling it to predict when maintenance will be required. Yet the functional principle of a smart factory is not limited by location. It can connect machines in different locations with others anywhere in the world, yielding one gigantic virtual factory. At Infineon, for example, facilities in Asia transmit their test results directly to the plant in Dresden, where these are factored into production processes.
Today’s robots are able to detect their surroundings and navigate independently, work side-by-side with humans, and even teach themselves the abilities needed to perform a new task.
Franka Emika’s “Panda” is just one example: The seven-axis robotic gripper arm is distinguished by its ease of handling, high agility, and sensitivity. A combination of numerous sensors, cutting-edge drive technology, and connectivity lends this collaborative robot high sensitivity, adaptability, and cost-effectiveness. Panda has a sense of touch, which enables it to perform complex assembly tasks alongside human colleagues without any safety barriers. The system is operated using apps - just like a smartphone - enabling it to quickly master new tasks. Meanwhile, the design and user interface allow for intuitive programming and flexible application scenarios. As an example, this makes it possible to integrate it into automated processes at a fraction of the cost that would typically be incurred for a robotics application of this kind.
As digitalization continues its unstoppable advance in factories, more and more opportunities for cyberattacks are opening up: According to the “IBM X-Force Threat Intelligence Index 2020”, the number of attacks on industrial systems in 2019 was 2,000 percent higher than in the previous year. Trusted platform modules (TPMs) are just one tool used to repel cyberattacks. These protect the identity and integrity of industrial PCs, servers, control systems, and even edge gateways. The TPM acts as a safe for sensitive data in smart devices and reduces the risk of data loss and production downtimes caused by cyberattacks. Moreover, manufacturers can keep the cost of maintenance low by updating devices’ software remotely and securely.
