IIoT: Smart manufacturing for efficiency and product safety
Last updated: 23 December 2025
The Industrial Internet of Things (IIoT) is the part of the Internet of Things (IoT) that focuses on industrial applications. This means it involves the networking of machines, systems, sensors, and entire systems within production facilities, as well as across whole supply chains or even globally. IIoT pursues several goals such as increased efficiency, cost reduction, process optimization, and improved transparency in production.
How does the Industrial Internet of Things work?
At the heart of the Industrial Internet of Things are intelligent machines, sensors, and control systems such as PLCs and edge devices. Sensors measure process parameters (e.g., fill levels or humidity); PLCs and edge devices collect these signals, can preprocess them locally, and forward them to higher-level systems or analytics platforms.
In the pharmaceutical industry in particular, pH values, viscosities, temperatures, particle contents, and similar parameters are common data points. A vital prerequisite for IIoT is the ability to record, monitor, and evaluate data almost in real-time.
In the second step, machines automatically evaluate this data. This often occurs at a central location through analytics platforms. These, in turn, provide feedback to the production systems, which are semi- or fully automated. This enables continuous monitoring of processes and optimization without manual intervention. The prerequisite for this is a networked production chain – even across entire supply chains. This results in advantages such as increased energy efficiency, predictive maintenance, and more precise logistics.
In addition, it is possible to create digital twins of production systems. These enable the optimization of processes and testing of the effects of changes without actual interventions.
Areas of application of IIoT
The Industrial Internet of Things is widely utilized in various industries, ranging from semiconductor technology to automotive and biotechnology. Especially in the pharmaceutical industry, with its complex processes and high requirements, it offers many advantages.
It supports GMP-compliant, networked production processes through improved monitoring and documentation. Additionally, it enables continuous process monitoring in aseptic processes, such as blow-fill-seal, thereby strengthening quality assurance. This allows highly automated production, ensuring maximum product safety and increased efficiency.
IIoT also increases system availability through predictive maintenance. Manufacturers benefit from safe products, higher efficiency, lower production costs, and compliance with regulations.
In other industries, such as chemicals, automotive, mechanical engineering, logistics, and energy supply, IIoT also enables automation, real-time tracking, optimized supply chains, and enhanced resource efficiency.
IoT & IIoT: related but different
IIoT is a subsector of IoT, which generally describes networked devices. While consumers often associate IoT with smart home applications, IIoT focuses on industrial applications.
Therefore, the focus is on security, reliability, scalability, and data protection. Processing data is the decisive competitive advantage that companies utilize.
The sensors and systems on an industrial scale are also different – they must be more robust, precise, and secure. Nevertheless, there are overlaps, for example, in sensor technology between smartphones and laboratory devices.
A general trend is the use of artificial intelligence (AI) and increasing data volumes. Therefore, the expansion of data infrastructure (e.g., the 5G network) is crucial.
Opportunities of the Industrial Internet of Things
The main opportunities of IIoT include:
- Higher product quality through real-time monitoring
- Process optimization through data-driven development
- Faster innovation through networked systems
- Data analysis through AI and big data
- Increased efficiency, reduced costs, and lower reject rates
- Support for regulatory compliance
Challenges: data protection and security
The biggest challenges of IIoT include data protection and data security. Companies must protect their critical infrastructure, for example, by encrypting sensitive production data.
Further challenges include high investment costs, integration of complex systems, and shortages of skilled workers. Especially in the chemical and pharmaceutical industries, there are strict regulatory requirements (e.g., GMP, FDA, EMA).
At the same time, however, networked devices can help to implement these regulations efficiently.
