The Essential Role Of Industrial Ethernet In The IIoT And Industrial Network Infrastructure

The Industrial Internet of Things (IIoT) and industrial networks are quickly becoming the backbone of our factories, warehouses, and industrial sites. But what role does industrial Ethernet play in this new connected landscape? Industrial Ethernet is essential for IIoT and industrial network infrastructure, providing reliable network solutions that enable more efficient operations and data management. In this blog post, we’ll discuss the importance of industrial Ethernet in IIoT and explore how it can help improve efficiency and productivity. We’ll also look at some solutions for networking your IoT devices with an industrial Ethernet system to ensure a secure, dependable connection.

What is IIoT?

The Internet of Things (IoT) is a term used to describe the network of physical objects—devices, vehicles, buildings and other items embedded with electronics, software, sensors, and network connectivity—that enables these objects to collect and exchange data. The IoT is a transformational force that is reshaping industries, economies and societies.

The industrial version of the IoT, often called the Industrial Internet of Things (IIoT), is designed to revolutionize manufacturing and other industrial sectors by improving efficiency, quality and safety while reducing costs. The IIoT can be thought of as an extension of Industry 4.0—the current trend in automation and data exchange in manufacturing technologies. It builds on the existing foundation of interconnected machines, people and systems within factories to enable greater visibility and control throughout the supply chain.

In order for the IIoT to reach its full potential, it must be built on a reliable and scalable Ethernet-based network infrastructure. Ethernet has been the technology of choice for mission-critical industrial applications for more than 30 years due to its high performance, deterministic behavior and proven reliability. These same attributes are now essential for supporting the demanding requirements of IIoT applications such as real-time data collection, machine-to-machine communication and predictive maintenance.

What is Industrial Ethernet?

Industrial Ethernet is a term used to describe Ethernet-based networking solutions designed for industrial applications. These solutions are typically ruggedized and designed to operate in harsh environments, making them well-suited for use in factory and process automation, transportation, and other mission-critical applications.

While traditional Ethernet networks have been increasingly used in industrial settings in recent years, true Industrial Ethernet solutions offer a number of important benefits that make them ideal for use in these demanding environments.

One key benefit of Industrial Ethernet is its ability to support deterministic communication. This is essential for many industrial applications where precise timing and predictability are critical, such as in motion control or process automation. By contrast, traditional Ethernet is best-effort only, meaning it can provide no guarantee of timely delivery of data packets.

Another important advantage of Industrial Ethernet is its support for real-time protocols such as EtherCAT and PROFINET. These protocols allow data to be exchanged between devices with extremely low latency, making them ideal for applications where fast response times are critical. Traditional Ethernet protocols such as TCP/IP are not well suited for real-time applications due to their relatively high latency.

In addition to the benefits mentioned above, Industrial Ethernet solutions are also typically much more robust and reliable than traditional Ethernet networks. This is due to the fact that they are designed specifically for use in demanding industrial environments where network downtime can be costly or even dangerous.

The Benefits of Industrial Ethernet

As the world increasingly becomes more digitized, the industrial Ethernet plays a critical role in the IIoT and industrial network infrastructure. The industrial Ethernet is a type of computer networking technology that is widely used in industries for process control and automation. It is designed to be rugged and reliable, able to withstand harsh environments and conditions.

The benefits of industrial Ethernet are many. Perhaps most importantly, it provides a high level of security and reliability for mission-critical applications. It is also scalable, so it can be easily expanded as needs grow. Additionally, it offers deterministic performance, meaning that data packets are delivered with consistent timing and without error. This is crucial for time-sensitive applications such as motion control or video streaming. Finally, it supports real-time communications, making it ideal for applications that require low latency or jitter.

The Different Types of Industrial Ethernet

There are several different types of Industrial Ethernet technologies that are commonly used in IIoT and industrial network applications. The most common type is Ethernet over twisted pair, which is the standard Ethernet cabling technology. Other types include Ethernet over fiber optic cable, Power over Ethernet (PoE), and Wireless Ethernet. Each of these technologies has its own advantages and disadvantages that should be considered when selecting the best type for a particular application.


Industrial Ethernet is an essential part of the IIoT and industrial network infrastructure. It provides high-speed data transfer, which ensures that all connected devices can communicate efficiently with each other and send/receive data quickly. Industrial Ethernet also increases security by enabling end-to-end encryption for all connections over a secure tunnel between two networked devices. Finally, industrial Ethernet allows easy scalability to accommodate future expansions as needed, making it a must have technology in today’s digital world.
