Open Platform Communications Unified Architecture (OPC UA)
OPC UA is an open interface standard that defines the mechanisms of cooperation in the industrial environment. It enables the industry to integrate its products and its production by information and communications technologies (ICT). Machines and plants can be redesigned as required by plug & work - irrespective of which manufacturers the machines and components originate. The VDMA develops with its member companies OPC UA Companion Specifications.
Around 270 participants from the circles of VDMA companies as well as the Chinese mechanical engineering and customer industries held fruitful discussions on trends, visions and content relating to the intelligent production of tomorrow.
The "umati" project, which was launched as an initiative of the VDW, has gained considerably in participation since its presentation at AMB 2018. With the launch of the OPC UA Joint Working Group (JWG) in February 2019, more than 60 companies worldwide are currently working on the further standardization of the interface for machine tools. The resonance of the customers is enormous and underlines the necessity of this work.
The "Plug & Work" framework was presented for the first time at LIGNA 2019. Under the umbrella of EUMABOIS and VDMA, this project develops uniform communication interfaces for the wood processing industry on the basis of OPC UA.
In order to exploit the potential of Industry 4.0, machines and systems must communicate smoothly with each other. The basis for this is a common language - mechanical engineering relies on OPC UA as an open and manufacturer-independent standard.
Three keynotes, 35 worldwide working groups, 353 registered visitors and many conversations with actors from all over the world. The World Interoperbility Conference takes the OPC UA community to the next level of collaboration!
On November 2nd the first "Meeting of the OPC UA Working Groups in the VDMA" took place. Presentations by experts from the OPC community inform the working group participants about the most important activities and innovations concerning OPC UA. In moderated parallel sessions an intensive exchange of experiences took place between the participants of different working groups.
OPC UA is an open interface standard that defines the mechanisms of cooperation in the industrial environment. The VDMA prioritizes its activities on this interface standard and gives an important orientation to the machine and plant engineering sector. The VDMA guideline “Industrie 4.0 Communication Guideline based on OPC UA” shows action steps that help to implement Industrie 4.0 communication in the company.
In the digital production world, machines from different manufacturers must be able to communicate with each other. This requires uniform standards, in the development of which the VDMA is significantly involved: the OPC UA Companion Specifications.
OPC UA Companion Specifications –an important prerequisite on the way to Industrie 4.0
The definition of uniform interfaces in production is a prerequisite on the way to Industrie 4.0. The VDMA is currently focusing on the interface standard OPC UA and is developing industry-specific OPC UA Companion Specifications. An OPC UA Companion Specification is an information model suitable for all manufacturers which represents the real interfaces between components, machines and systems.
Communication with OPC UA
An important basis for the successful introduction of Industry 4.0 is the manufacturer-independent exchange of data in production. The open interface standard OPC UA is increasingly established for this purpose. The VDMA guideline shows how companies can successfully introduce industry 4.0 communication with OPC UA.
