Terminology regarding Industry 4.0 (glossary of the VDI GMA technical committee 7.21 »Industry 4.0«)

The VDI GMA technical committee 7.21 »Industry 4.0«, under the direction of Prof. Dr.-Ing. Ulrich Epple from the RWTH Aachen, is working on a basis for the understanding of the standard terminologies, reference models and architectural concepts for Industry 4.0.

This is happening on the basis and for further devolpment of the existing standardization in the area.

Within Industry 4.0 the languages of production and information and communication technology (ICT) are growing together. There are however differences and unclarities regarding the terminlogies of Industry 4.0 which have historical reasons. The workgroup »Terminology« under the direction of Mrs. Dr.-Ing. Miriam Schleipen from the Fraunhofer IOSB is working on a common »basis« (terminology) of Industry 4.0 in terms of linguistic and mental contructs. Existing norms and standards of the areas of ICT and production are the base for these constructs.
