order , a maintenance technician carrying out maintenance work or a TUV inspector accepting equipment . For users of the devices , the two specifications are important . They specify how automatic identification ( DIN SPEC 91406 / IEC 61406 ) and structured documentation of product information ( VDI 2770 ) should work . Plant operators need to know how they can access the digital product data , how it is presented and in what form they can process it further .
Digital product pass from AS-Schneider
The role that standards play in the process industry is best illustrated by an example . Valve manufacturer AS- Schneider has introduced a Digital Product Pass ( DPP ) for its products . With the free service , E Series Manifolds , Monoflanges , VariAS-Blocks and DBB Piping Ball Valves are marked with a one-to-one QR code according to DIN SPEC 91406 / IEC 61406 . The user simply scans the code or enters the individual serial number at www . qr4v . de . This gives them immediate access to technically relevant static product information and allows them to download the data , drawings , operating and maintenance instructions , certificates , material certificates and spare parts information . The DPP solution is a static digital twin that provides only the documents and information that are available at the time of handover between the supplier and
customer . This allows a physical product to be virtually mapped .
Standardised data , smooth exchange
In addition to complying with the DIN SPEC 91406 / IEC 61406 and VDI 2770 standards , manufacturers will have to ensure that product data exchange with customers and other stakeholders runs smoothly in the future . The Digital Data Chain Consortium ( DDCC ) industry committee is currently looking at cloud-based information exchange platforms ( IEPs ) in this regard . The members of the committee are currently examining SAP ’ s Asset Intelligence Network , Endress + Hauser ’ s Netilion platform and other solutions . The aim is to enable stakeholders to access product data centrally via one or more IEPs to facilitate more efficient document management .
Asset Administration Shells and Industry 4.0
The DIN SPEC 91406 / IEC 61406 and VDI 2770 standards also play a decisive role in the concept of Asset Administration Shells ( AAS ) as part of the German government ’ s Industry 4.0 platform . In principle , these ‘ shells ’ combine all product-related information in one place and are divided into categories - referred to as submodels : DIN SPEC 91406 / IEC 61406 belongs to the ‘ Identification ’ management shell sub-model , while VDI 2770 belongs to the ‘ Documentation ’ sub-model . This defines

the appearance of various segments of the digital twin . The Asset Administration Shell is thus relevant throughout the entire life cycle of the product . However , its concept goes even further than the static digital twin that AS- Schneider already offers today . For example , it also includes real-time data from plant operation via sensor technology . In this case , this is then a ‘ dynamic digital twin ’. All aspects mentioned here will be relevant for digitalisation in the process industry in the future – also to produce more sustainably and environmentally friendly .
