IIoT

Industrial Internet of Things (IIoT) explained simply

Imagine your machines talking to each other – and providing real insights in real time. That is IIoT: industrial plants, sensors and actuators connected to each other and collecting data. This way you can recognise early when a machine needs maintenance or where production processes can be optimised – without guessing or hocus-pocus. Real-time data instead of gut feeling makes your plant smarter and more efficient.

Background information

IIoT – short for “Industrial Internet of Things” – describes an ecosystem of connected devices, sensors, controllers and software systems used in industrial environments. The goal is to capture data from physical assets in real time, analyse it and automatically translate it into actions – e.g. predictive maintenance or process optimisations. By using edge, fog and cloud computing, large volumes of data can be efficiently processed and business-relevant insights generated. Modern IIoT systems enable data-driven decisions and open up new business models in the production and logistics environment.

The roots of IIoT go back to classical distributed control systems (DCS), but have evolved into open, standardised platforms based on industrial standards such as ISA 95, MQTT or OPC UA. The focus today is on interoperability between machines, SCADA systems, ERP solutions and AI-supported analyses. Platforms such as those from Cisco, AWS or PTC connect sensors, networks and business logic into integrated solutions. There are also advances in security architecture: the Industrial Internet Consortium (IIC) defines testbeds, standards and reference architectures to establish reliable and scalable IIoT solutions globally.

IIoT vs. IoT – What is the difference?

Although IIoT is based on the concept of the general “Internet of Things”, there are fundamental differences in objectives, technology and requirements. While classical IoT is mostly in the consumer sector (e.g. smart homes, fitness trackers or connected household devices) and aims to make everyday life more comfortable, IIoT pursues economic and productive goals: efficiency increase, process control, reliability and cost optimisation in industrial contexts.

Technologically, IIoT differs through more robust components, real-time capable communication, longer device life cycles and higher requirements for reliability, maintainability and IT/OT security. Errors in consumer IoT may lead to a power failure in the living room – in IIoT, however, they can result in costly production downtimes or safety risks.

Typical use cases and industry examples

IIoT is used in numerous industries – particularly where large amounts of machine data must be made available in real time:

  • Predictive maintenance
    Machines report unusual vibrations, temperatures or operating times at an early stage. This allows maintenance intervals to be optimised, downtimes reduced and spare part availability improved. Examples: printing machines, CNC centres, turbines.
  • Remote monitoring and remote maintenance
    In the energy sector or for manufacturing plants, conditions, processes and controls can be monitored centrally. Maintenance teams avoid unnecessary on-site visits.
  • Quality monitoring and process optimisation
    In the food, pharmaceutical or automotive industry, sensors continuously provide information on pressure, humidity, speed or temperature – and automatically give feedback to machine controls.
  • Energy consumption analysis and reduction
    IIoT helps to identify hidden “energy guzzlers” and optimise machine profiles for efficiency – a relevant use case in the chemical industry, foundries or logistics.
  • Asset tracking & logistics optimisation
    By integrating with RFID, GPS and ERP systems, materials, containers or components can be tracked seamlessly. This is particularly important in the aerospace, construction or automotive industries.
