Industrial Internet Consortium Updates Its IIoT Technical Report

The Industrial Internet Consortium (IIC), an organization dedicated to transforming business and society by accelerating the adoption of the Industrial Internet of Things (IIoT), has announced V2.2 of its "Industrial Internet Vocabulary Technical Report," one of six IIC technical reports that serve as de facto IIoT industry guidelines on vocabulary, architectures, security, analytics, connectivity and business strategy. According to the IIC, the report provides a common set of definitions for IIoT terms for anyone working in the IIoT across a range of industries.

The report includes a new definition for "digital twin" and eliminates "virtual entity" in favor of "digital representation." Other terms added to the report include "physical entity" and "physical entity of interest," describing a physical object such as factory equipment that could be monitored or that is already being monitored by an IoT system. "IoT sensor" and "IoT actuator" were also added.

"We update the 'Vocabulary Technical Report' annually with new terms that align with key IIoT trends," said Bob Martin, the co-chair of the IIC Vocabulary Task Group and the IIC Steering Committee Member, and a senior principal engineer at MITRE Corp., in a prepared statement. "This year, the report focuses on digital twins—software replicas of physical devices that run simulations of systems and leverage IoT, AI and analytics technologies."

"Vocabulary terms can be quite concise, accurate and sometimes terse," said Erin Bournival, the co-chair of the IIC Vocabulary Task Group and a distinguished engineer in the Office of the Corporate CTO at Dell EMC, in the prepared statement. "However, a definition can be expanded to give the big picture for a broader understanding of the vocabulary term. For example, the definition of digital twin is a digital representation sufficient to meet the requirements of a set of use cases. That definition can be expanded by adding the definition of digital representation and so on. While it may sound complicated, an agreed upon vocabulary helps authors create definitions and documentation that answers stakeholders' questions."

The IIC will continue to revise the IIC "Industrial Internet Vocabulary Technical Report" with definitions for new IIoT terms. The report and a list of IIC members that contributed to it can be found at the IIC website.
