IoT, IIoT, Industry 4.0: What’s the difference and does it matter?

While related, these terms are not interchangeable. Each entity has a different set of stakeholders, goals and implications.

Let’s start with IoT. There is some speculation about the first use of Internet of Things (IoT) as the term to describe the interworking of devices but most sources agree that it was first coined by Kevin Ashton in 1999. The basic definition is the connection of a device to the Internet and/or other devices. Today, IoT usually refers to consumer-level goods like light and temperature controls, wearable biometric devices and, of course, smart phones. Although the connectivity afforded by these devices is certainly beneficial, device failure does not result in an emergency situation. IIoT is driven by consumer-level product manufacturers and innovators.

Commentators have sarcastically joked that the IIoT is the same as the IoT, it’s just located on the factory floor. Not quite. General Electric first used the term “Industrial Internet” in 2012, shepherding in the Industrial Internet of Things (IIoT). Like the IoT, the IIoT is the connection of devices over the Internet, but with a focus on the transfer, command and control of mission critical information and responses. The IIot “goes to work” in fields like energy, military, public safety and transportation – where reliability and accuracy are not optional. IIoT initiatives and growth are championed by machine to machine (M2M) innovators and creators.

Industry 4.0 was introduced in 2011 as a German government initiative dedicated to ensured competitiveness for the manufacturing industry. The term is used to identify the fourth industrial revolution, preceded by revolutions in mechanical production, mass production, and information technology. While both IoT and IIoT operate at a business level, Industry 4.0 remains a primarily government and academic-based movement, with minimal private business involvement.

All three of these entities are focusing on ways to make systems faster and – perhaps more importantly – secure. At Sealevel, we stand to have the most impact within the IIoT, and the trickle-down effect that has on IoT. We’re proud of the strides we’ve made in improving mission critical communication and look forward to expanding our reach to offer more cloud-based and wireless products.

    Hello

    I was reading your article
    http://www.sealevel.com/community/blog/iot-iiot-industry-4-0-whats-the-difference-and-does-it-matter/

    Very interesting and a good description of the differences between IoT, IIoT and Industr/ie/y) 4.0, even though others argue that IoT can be used as a term for all of this.

    In the end you write “All three of these entities are focusing on ways to make systems faster and – perhaps more importantly – secure.”
    Do you have a scientific reference or source indicating how connecting Operational Technology in a factory to a cloud service on the Internet makes it more secure?
    Im doing a thesis on IoT in factory automation and my initial impression is that connecting OT is perceived as a major security risk.

    Best regards
    Andreas Sylvan

    Thanks for your comments, Andreas. As mentioned in our blog, security is one of the primary challenges facing IoT, IIoT, Industry 4.0 and any other label applied to the cloud-based technical revolution. While we can’t direct you to a scientific reference, we have found that our customers do see benefits from immediate, cloud-based access to their data. For example, customers have told us they prefer vendors that can interface with their systems without requiring access to their internal network. With the degree of scrutiny IoT solutions are facing, vendors should be focused on providing the most secure solutions possible. Good luck with your thesis.
