IIoT Progress Report
Industrial Internet of Things 2022 Progress Report Industry experts provide their perspective on the state of the Industrial Internet of Things. Our 2022 progress report explores how IoT technology is being implemented into complex industrial environments as part of digital transformation strategies, and leverage a wide range of connectivity solutions.
Connectivity is the foundation for smart systems – and smarter machines, and the gateway to achieving digital transformation in the factory. INDUSTRIAL INTERNET OF THINGS (IIoT) technology is driving a wide range of new networking solutions, from the sensor to the cloud, that are enabling new levels of digital innovation with a goal of transforming global manufacturing. For the 2022 IIoT progress report, IEB reached out to industry experts to get their insights into the development of the Industrial Internet of Things and perspectives on the megatrends shaping and enabling development of the IIoT. Key technologies include the emergence of Single Pair Ethernet and Ethernet-APL, software connectivity trends provided by OPC UA and MQTT, and new options for leveraging solutions for wireless systems and machine learning. But experts also note that all the technology needed is available, and it’s more a matter of adoption. We’re just starting to understand how to make IIoT happen in a way that is simple and affordable for most businesses.

SPE, OPC UA and MQTT
Connectivity solutions drive innovation According to Dr. Al Beydoun, President and Executive Director at ODVA, the leading megatrends driving the IIoT forward include the emergence of two-wire Ethernet connection technologies, OPC UA for information applications and the use of MQTT to create cloud connectivity.
Technology megatrends
“ODVA supports Internet Protocol (IP) to the industrial edge by advancing 2-wire Ethernet technology such as Ethernet Advanced Physical Layer (Ethernet-APL) and Single Pair Ethernet (SPE). Multi-stack IIoT devices have the ability to support EtherNet/IP to real-time controllers, OPC UA to on-premise IIoT information applications, and MQTT to cloud IIoT applications,” Beydoun told IEB recently. “MQTT is a lightweight publish/subscribe
network protocol that is an option to transport data from automation devices, including those running on EtherNet/IPTM, to the cloud. Minimal network bandwidth is required making MQTT a scalable method to connect existing devices to the internet at a low cost. MQTT adoption has been gaining momentum across automation, but in particular in industries such as automotive and oil & gas,” Beydoun said. He added that prognostics is a critical IIoT trend that will change the way that maintenance is approached and what expectations are regarding production down time. “The ability to monitor for excessive vibrations and sounds or to look for out of tolerance changes such as media pressures, motion travel times, or electrical resistance levels can provide early warnings of device degradation. This can allow for time to order and replace faulty components, including an extra buffer in case of part number mistakes,
