The Industrial Internet of Things (IIoT) is an increasingly important concept in modern industry. It goes beyond simple IoT applications by driving efficiency improvements across the manufacturing sector through the intelligent connection of devices and data sharing.

Challenges in Traditional Industrial Automation

In traditional industrial automation systems, equipment on the factory floor, such as PLCs (Programmable Logic Controllers) and HMIs (Human-Machine Interfaces), typically need to be connected to SCADA (Supervisory Control and Data Acquisition) systems and MES (Manufacturing Execution Systems) through specific engineering techniques. This connection often relies on communication protocols like OPC UA, with an OPC server managing the communication between devices. However, in reality, MES systems and SCADA systems are not always directly connected, leading factories to rely on paper processes and manual operations to transfer data. This approach is not only inefficient but also requires significant human resources.

Innovations and Advantages of IIoT

IIoT offers a revolutionary solution. Its core idea is to eliminate the cumbersome manual operations and paper processes of traditional systems by connecting all factory equipment—ranging from PLCs, sensors, and routers to cameras and telephone systems—to a unified namespace. This allows data to flow seamlessly. Through this method, SCADA, MES, ERP (Enterprise Resource Planning), and other systems can directly subscribe to the data they need from this namespace, greatly simplifying system integration.

This new architecture not only reduces the engineering costs required for integration at each level but also allows businesses to expand and upgrade their automation systems more flexibly. Enterprises only need to connect new devices to the namespace without having to pay additional engineering fees for each new node. This shift helps companies reduce human intervention, lower operational costs, and improve overall efficiency.

Practical Applications of IIoT

In the traditional architecture, while MES systems can connect to ERP systems, they typically cannot directly access data from factory floor equipment, as this data needs to be accessed indirectly through SCADA systems. IIoT breaks this limitation by enabling all systems to share data within the same namespace. For example, devices using IIoT protocols can automatically publish data to the namespace, from which the enterprise’s SCADA, MES, ERP, and cloud systems can directly subscribe to the data, eliminating the barriers between systems.

Thanks to the widespread application of IIoT, companies no longer need to pay high engineering fees for the integration of each new device. Manufacturers can pre-configure IIoT protocols in their devices before they leave the factory, allowing them to automatically connect to the namespace upon installation, enabling various systems within the enterprise to directly access data. This significantly reduces the integration costs for companies.

The Importance of IIoT

The importance of IIoT lies not only in its connection of devices to infrastructure but also in its connection of devices to people. Through a unified namespace, all of an enterprise’s systems can easily access device data without the need for complex engineering design and manual intervention. This integration method drives the digital transformation of enterprises, enabling them to quickly respond to market changes, increase production efficiency, and reduce operational costs.

Therefore, IIoT is not just a technological innovation in industrial automation but also a critical pathway for enterprises to achieve a digital factory. By leveraging IIoT, companies can build an intelligent, data-driven production environment, gaining a competitive edge in the global market.
