The eCl@ss board founded the Digitalization Expert Group in the spring of 2017 to provide a platform for all digitalization-related issues, and to help work through these issues in a structured and directed way.

Members of the DEG are recruited from among experienced subject-area experts, who are delegated by their companies to address the topic of eCl@ss, and who are themselves active in the areas of smart manufacturing and/or the internet of things (IoT).
Participation in the DEG is free of charge, and is open to all interested subject-area experts.



DEG tasks

DEG’s main focus is on monitoring, managing and supporting projects, as well as on coordinating all eCl@ss activities in the areas of digitalization.

•    Collection and distribution of information, both internally and externally to eCl@ss
•    Review and initiation of research work and projects
•    Cooperation with other committees and associations
•    Compilation of requirements 
•    Provision of advice to the eCl@ss board
•    Preparation of decision documents

Always with a focus on digitalization.




In a white paper, experts from the Digitalization Expert Group (DEG) describe the contribution eCl@ss can make to digitalization and machine-to-machine communication today and in the future.


Because the eCl@ss standard can accommodate a vast number of technical properties, it marks an ideal first step in targeting digital twins.  This brochure is intended to offer guidance in explaining how using eCl@ss can foster smart manufacturing.
