The VDMA develops the world language of production - this is the central topic of the OPC UA online series of the VDMA. The kick-off event on 30 June 2020 focused on the role of the VDMA in the context of Industry 4.0 and internationalisation as well as the future of mechanical engineering in times of digitalisation.
In the "OPC UA for Machinery" Companion Specification all basic information models resulting from the work of all OPC UA working groups are combined. Now the first building blocks are ready for comment.
The VDMA intends to set up a working group on the topic of "Industrie 4.0 with OPC UA" in Brazil. The kick-off was a first web conference on May 28, which was attended by about 30 company representatives. You too can participate and help to advance Brazil's productivity and competitiveness by introducing this interface standard.
Internationalization of existing OPC UA specifications and publication of new interfaces for extrusion
In the future, VDMA and VDW will jointly promote the use and dissemination of OPC UA standards for the entire mechanical engineering industry under the umati brand.
In the new episode of the OPC Foundation Podcast Andreas Faath explains the role of the VDMA in the development of OPC UA Companion Specifications. The head of OPC UA in VDMA gives an overview of the active working groups in VDMA and explains the process underlying the development of a Companion Specification.
Extensive work is currently being carried out under the umbrella of the VDMA to standardize the interfaces of machines and components in individual sectors. In the "OPC UA for Machinery" Companion Specification all basic information models resulting from this work are combined.
Cross-industry collaboration and harmonization of interface standards is crucial for Industry 4.0 and the production of the future. This was also shown at the second meeting of all OPC UA working groups in the VDMA.
The leading manufacturers of joining technologies have decided to develop an OPC UA Companion Specification (CS) for joining technologies together with the VDMA Robotics Automation Association.
In November 2019, experts from all over the world met for the OPC Day in Helsinki. Now both the video recordings and the PDF versions of the presentations are available and provide an overview of the latest news about this interface standard.
Around 50 VDMA members visited Lenze SE in Hameln on 16 January. The highlight of the experience exchange event was the company's Plug & Produce Showcase, which illustrates the advantages of OPC UA in a very concrete way.

Web seminar series "OPC UA - The world language of production" successfully completed
In 12 web seminars, experts from various branches of the mechanical and plant engineering industry presented their respective OPC UA standards in the period from June 30 to August 7, 2020. About 3,800 registered participants informed themselves in the 60-minute sessions about the approaches and contents of the OPC UA Companion Specifications for our industry.
