AAS Submodel Templates

The structuring of machines, plants or systems is an essential task in engineering to make the complexity of a technical system manageable. IEC 81346 standardises a concept of structuring based on various aspects that an object (asset) can have. In this sense, a system always consists of several objects, which means that the system (composite asset) also has corresponding aspects. Figure 1 shows three of the aspects as examples. The standard describes a total of five aspects:
• What an object is supposed to do or what it actually does – Function aspect (=)
• The means by which an object does what it is supposed to do – Product aspect (-)
• Planned or actual location of the object – Location aspect (+)
• Group of objects that have the same properties – Type aspect (%)
• A freely definable aspect that must be specified by the creator – Other aspect (#)

Handover Documentation

02004

2.0

Published

The Submodel Handover Specification defines a standardized exchange format for information or documentation for a specific asset. The scope of this Submodel is to increase the interoperability between the parties that are exchanging asset documentation. These parties can be manufacturers of components or complete machines, or operators using these components or machines. In case a machine manufacturer sells a machine to a customer (operator), the manufacturer hands over the machine and its documentation in form of an AAS with the Submodel “Handover Documentation”. The documents provided can contain information required for e.g. correct design, installation, commissioning, spare parts stocking, operation, cleaning, inspection, maintenance, and repair. In addition, there are legal regulations that stipulate the existence of certain manufacturer documents, such as Communauté Européenne (CE) declarations of conformity, Atmosphères Explosives (ATEX) certificates, or material certificates. Besides the structure of a Submodel and the exchange format of an AAS, this Submodel standardizes the meta data that comes with the asset documentation and the classes that classify the type of the document. With these standardized meta data and classes, the asset documentation can be automatically integrated in the customer’s document management system, backend system, or any other system. The meta data as well as the classification classes of this Submodel are based on the VDI Guideline VDI 2770 Blatt 1 “Operation of process engineering plants – Minimum requirements for digital manufacturer information for the process industry” [7]. While the classification of documents according to VDI 2770 is mandatory, additional classification classes can be added.

Generic Frame for Technical Data for Industrial Equipment in Manufacturing

02003

2.0

Published

This Submodel template aims at interoperable provision of technical data describing the asset of the respective Asset Administration Shell. Central element is the provision of properties, ideally interoperable by the means of dictionaries such as ECLASS and IEC CDD (Common data dictionary).
The intended use-case is, that a manufacturer of industrial equipment describes assets (type or instance), which are provided to the market, by the means of technical data (properties), which are interoperable and unambiguously understood by the other market participants, such as system integrators or operators of industrial equipment. For providing individual industrial equipments to the market, also a supplier is covered by the use-case (for this purpose seen as functioning as manufacturer).
This Submodel template specifies a basic set of SubmodelElements in order to bring about the necessary information according to this use-case.

Energy Flexibility Data Model

02076

1.0

In Development

Coming soon

The proposed submodel template designed to enable an optimally energy-flexible operation across systems within industrial enterprises and to facilitate the communication of energy flexibility between industrial companies and energy market-related services.
The model provides a generic description of energy flexibility, focusing on a minimal set of parameters and metrics, but encompassing technically and energetically relevant information necessary to describe energy flexibility. It serves as a central foundation for communication within a company unit as well as externally with software applications (services) mediated via a marketplace platform. It does not aim to create a digital twin as a virtual and fully realistic representation of energy flexibility. This approach limits the complexity and volume of exchanged information while avoiding the exchange of sensitive production and process data.

Digital Nameplate for industrial equipment

02006

3.0

Published

This Submodel template aims to provide asset nameplate information to the respective Asset Administration Shells in an interoperable manner. Central element is the provision of properties [7], ideally interoperable by the means of dictionaries such as ECLASS and IEC CDD (Common Data Dictionary). The purpose of this document is to make selected specifications of Submodels in such manner that information about assets and their nameplate can be exchanged in a meaningful way between partners in a value creation network. It targets equipment for process industry and factory automation by defining standardized meta data.
The intended use case is the provision of a standardized property structure within a digital nameplate, which enables the interoperability of digital nameplates from different manufacturers.
This concept can serve as a basis for standardizing the respective Submodel. The conception is based on existing norms, directives and standards so that a far-reaching acceptance can be achieved.
Beside standardized Submodel this template also introduces standardized SubmodelElementCollections (SMC) in order to improve the interoperability while modelling partial aspects within Submodels. The standardized SMCs include address and asset product marking.
In addition to the general information for Industrial Equipment listed in this document, it may be necessary to supplement the digital nameplate with additional information for specific areas of application, e.g. for explosion safety or radio. Information for the digital nameplate for additional areas of application are defined in supplementary Submodel templates.

Safety instrumented functions (SIF) for the process industries

02064

1.0

In Development

Coming soon

The main goal is to propose submodels consisting of safety list of properties (SLOPs) of safety instrumented functions (SIF) in alignment with IEC 61511.
The SLOP included in this new submodel can then be aligned with and integrated into the IEC CDD. The submodel template will build on the work of two ongoing initiatives: 1) results from the Norwegian joint industry project named Automated process for follow-up of safety instrumented systems (APOS 2.0), including an UML model developed with basis in requirements and definitions in IEC 61511. 2) Results from the NAMUR WG1.3 on Information Management and Tool who is developing a similar UML model. Alignment activities have been carried out between NAMUR and the APOS 2.0 project, and we would like to involve persons from both organizations in preparing the details of the proposed new submodel templates.
Although this specific proposal pertains particularly to establishing thesubmodel for safety instrumented function (SIF), we recognize the need for expanding our scope to establish a set of relevant submodels under the domain of ‘functional safety for process industries’, for example:
-Submodel for safety instrumented system (SIS) components
– Submodel for SIS subsystems
– Submodel for Safety requirement specification (SRS)
– Submodel for data collection in SIF operation.

Data Retention Policies

02056

1.0

Published

This Submodel describes a common representation of data retention policies that can be applied to elements in the Asset Administration Shell via semantic identifiers. Based on this information, it is possible to automate the reduction, archiving, or removal of data stored in the Asset Administration Shell. Such data can be, for example, raw sensor data, large images, sensitive data, or any data that becomes obsolete over time.
A data retention policy defines how long data must be stored before it may be deleted. It also provides information about the policy provider, the specific requirement or law that enforces the policy, and the timeframe between which the policy is in effect. Additionally, the authorship of each policy can be traced through an audit log, in which all changes to the policy are documented. Based on this information, an automated service can apply and validate each policy against the data stored in the Asset Administration Shell and reduce, archive, or remove the data as necessary.
This Submodel allows a set of policies to inherit from another set of policies so that an existing policy can be extended or adjusted to more specific use cases. For example, business policies may be overridden or extended by contracts with more specific policies or longer retention periods.
The enforcement of data retention policies described by this Submodel are outside the scope of this document.

In Development

Coming soon

In the submodel Automation Engineering, information of engineering in the area of electrics, hydraulics, pneumatics and control (general automation engineering) is to be covered. Components of automation engineering are selected, structured, placed and connected in engineering tools. The model consistently continues the concepts of the AAS and transfers them to the engineering of plants and systems. As a link between the requirements definition of a resource and the actually used component and its installed instance, it makes a significant contribution. The objective is to make the existing information available to other software systems in a formally standardised form. This brings considerable added value to a large number of use cases over the life cycle if they are semantically processed. Among other things, collaborative engineering, derivations for production, maintenance and documentation are taken into account. The model will be based on relevant standards such as IEC 81346 and IEC 61355 as well as existing submodels such as Hierarchical Structures enabling Bills of Material and Generic Frame for Technical Data for Industrial Equipment in Manufacturing.

Technical Data for Fiber Optic Microduct Cabling for Broadband Expansion

02061

1.0

In Development

Developed in cooperation with InterOpera.
The objective of the submodel „Technical Data for Fiber Optic Microduct Cabling for Broadband Expansion“ is to standardize the technical characteristics of micro tubes and their composites. This is due to the fact that although the planning and documentation of fiber optic lines is carried out digitally, the properties of the pipe assemblies into which fiber optic cables are blown after professional installation are not uniformly defined. This has so far prevented, for example, the comparability of their specifications across manufacturer boundaries and integration in planning according to the Building Information Model (BIM). Since the characteristics belong to the technical specifications, they are standardized in an extended submodel using the IDTA submodel „Generic Frame for Technical Data for Industrial Equipment in Manufacturing“ (IDTA number: 02003, version: 1.2) as a base. The standards DIN EN 60794-5-10, DIN EN 60794-5-20, DIN EN 50411-2-4 and DIN 47609 are taken into account.

Technical Data for Automated Guided Vehicles in Intralogistics

02047

1.0

Published

The material flow in the factory will increasingly be driverless and autonomously controlled. With the growing penetration of production with AGVs, these will also take on very specific transport, handling and, with the right setup, possibly also assembly or manufacturing tasks.
Suppliers of AGVs will continue to develop specific capabilities and features for their vehicles and possible attachments. This will inevitably lead to the situation where different types of vehicles and vehicles from different manufacturers have to be operated in one production environment. These mixed fleets have to be integrated in the overall driverless transportation system and controlled via a central or decentral control system. In most cases this control system will be linked to the ERP or MES system where it is receiving the transportation orders from. Control systems can be proprietary systems of the vehicle supplier or manufacturer-independent systems. With increasingly mixed fleets in operation manufacturer-independent control systems will be more widespread on the market.
Against this background, a digital twin in the form of an AAS for the vehicles is to form the data basis for the integration of the individual vehicles into an overall system. The Submodel „Technical Data for Automated Guided Vehicles in Intralogistics“ aims to identify the necessary information for integration and standardize it with an AAS Submodel specification. In addition to the integration aspect in an overall system during the engineering phase, the Submodel should also take into account technical data needs for commissioning, operation and maintenance.

Workstation Worker Matching Data

02046

1.0

Published

The focus of the Submodel “Workstation Worker Matching Planning” is on the employee scheduling and operational deployment of employees who carry out manual activities in production. The activities performed can include, for example, the processing of products, their assembly, the operation of machines and systems, as well as their loading and set-up, transportation, quality inspections, maintenance, servicing and much more. With the high level of automation and increasing digitalization and autonomation of production the requirements for the planning and management of employees are changing. In future, employees will have to be deployed in a more situational and targeted manner according to their qualifications and skills. The fixed assignment of an employee to a workstation for an entire shift, in which the employee covers all the skills potentially required at the workstation, will no longer be the norm.
In an Industry 4.0 production environment, different requirements are placed on employee scheduling than in a traditional production system, in which employees are manually assigned, usually by the group leader. In Industry 4.0 production, employees and the (autonomous) automation system will have to work together synergistically and employees with the appropriate qualifications or skills will have to be scheduled and managed according to the situation. When qualified personnel resources are scarce, the optimal allocation of qualifications and skills is particularly important.
The current approach of employee scheduling (shift planning) and operative employee deployment by the group leader will reach its limits in future Industry 4.0 production. The classic qualification matrix for planning the necessary qualifications and skills will also no longer be sufficient. The manual creation and maintenance of the matrix will get at its limits and is not interoperable.
The „Workstation Worker Matching Data“ Submodel is used to map the general-, ad hoc- and order-dependent demand of a workstation for qualifications and skills. In addition, further information will be provided by the Submodel that are relevant for operative worker deployment and employee scheduling.

Data Model for Asset Location

02045

1.0

Published

The location of static or mobile objects (assets / goods / trackables) and, if applicable, the origin and destination of transport processes are naturally the most important information in transport and internal logistics. In the past, the postal address or a simple location description (e.g., hall B, aisle 3) or a GNSS coordinate (Global Navigation Satellite System, like GPS) was sufficient as location information for controlling logistics processes. With the increasing propagation of localization technologies such as Ultra-Wideband (UWB), BLE (Bluetooth Low Energy), RFID (Radio-Frequency Identification) and others, the continuous and precise tracking of objects becomes possible at reasonable costs. This opens up new possibilities for the automation, monitoring and analysis of goods flows and internal transportation tasks. It is also possible to measure masses of localization data for short distances within buildings, which is why the integration of a localization solution into warehouse systems or production lines is becoming increasingly popular. The systems for localization are usually referred to as real-time location systems (RTLS). Automated guided vehicles (AGVs) and autonomous transport robots with free navigation (AGVs) are also increasingly being used for internal transportation tasks. These are another driver for the use of localization technologies in companies. Location data for assets are determined by different localization systems during the life cycle and even at the same point in time more than one system can deliver a location information. Today location data originate from a variety of non-interoperable systems, for which the data model for the localization information is not standardized. Since asset location data are generated and used by different systems, for different use cases, in different life cycle phases and by different organizations it makes particular sense to manage the location data in the AAS of an asset in the form of a standardized Submodel.

Technical Data for Injection Molding

02044

1.0

In Development

Within the scope of the project, several AAS submodels for injection molding operations are adressed, based on the already existing IDTA submodel „Technical Data“ (IDTA number: 02003, version: 1.2). The submodels aim at standardizing the minimum necessary features of technical data for injection molding operations, which can represent the technical capabilities of injection molding machines, injection molds and peripheral equipment. For example, a submodel „Technical Data for Injection Molding Machine“ specifies the common features of injection molding machines. Similarly, submodels for injection molds and peripheral equipment specify additional features. All targeted submodels provide manufacturers with the interoperable description of technical data that is clearly understood by other market participants such as system integrators and operators. A key added value of the submodels for operators is the minimization of the effort required for the technical feasibility check with regard to machine capability by the collection of the digitized and standardized characteristics of technical data.

Process Parameters Instance

02031-2

1.0

In Review

Coming soon

This Submodel defines instance-specific information of Process Parameters and provides a framework to describe the output parameters for processes of industrial equipment. This Submodel does not require any knowledge about how a process is executed and in which order. It is solely focused on the structured description of data reported by a process.
The need for a dedicated Process Parameters Submodel is to enable the interoperable description and transfer of data between assets. The concept is based on process knowledge from various organizations in the automotive wire harness industry. Although the associated use cases are from the value chain of wire harness manufacturing, the aim of the working group is to develop a generalized Submodel that can be used for a wide variety of products and industries.
This Submodel is intended for the description of output parameters of a process and should be used in combination with the Hierarchical Structures Submodel to define the sequence of process execution and hierarchical requirements.

Predictive Maintenance

02048

1.0

Published

The Submodel Predictive Maintenance aims to standardize metadata and information from various sub-systems within highly automated production lines, that are required for developing and deploying predictive maintenance solutions (PdM solutions). This facilitates integration and interoperability of sub-systems of production lines into PdM solutions. In addition, their data can be evaluated in a more targeted manner in the context of the PdM application in order to reduce unplanned machine downtimes. Accordingly, the PdM solutions can in turn provide maintenance-relevant information via the AAS, e.g., on predicted remaining lifetime and/or the probability of failure.
In general PdM aims to predict the end of useful life of a specific device or component (asset). The remaining useful life (RUL) is the duration until this end of life is reached, and the asset must be replaced or a maintenance action must be performed. RUL can be measured in time or other wear relevant units such as a distance/length or numbers of process cycles. The scope of the Submodel is mainly on data related to PdM, not on the prediction model itself.
Thus, this submodel does not contain the implementation details data-driven and AI-boosted models for PdM,. As a matter of fact, this submodel is merely structuring the data attained from an algorithm or model (physical or mathematical) for better utilization in planning and maintaining physical assets in a shopfloor.
The Submodel Predictive Maintenance aims at interoperable provision of information describing PdM topics in regard to an asset. Central element is the provision of properties [7], ideally interoperable by the means of dictionaries such as ECLASS and IEC CDD (Common Data Dictionary). The purpose of this document is to make selected specifications of Submodels in such manner that information about assets can be exchanged in a meaningful way between partners in a value creation network. It targets components of machines or plant sections which are themselves sub-systems of factories or plants and predictive maintenance applications for these components and sub-systems.
The conception is based on existing norms, studies of common practices at enterprises, directives and standards so that a far-reaching acceptance can be achieved (see also section 1.3).
In the context of maintenance, it is important to understand that PdM for industrial applications is a niche but rapidly growing segment within the much broader field of maintenance use cases. Therefore, only functionalities which are directly enabled because of PdM, namely predicted remaining useful lifetime of an asset, are the main focus of this submodel. Topics out of the scope of this submodel are maintenance instructions and preparation, corrective maintenance, predetermined or condition-based maintenance. Figure 1 shows a schematic overview on types of maintenance adapted from DIN EN 13306. Appendix B provides a future vision for the embedding of PdM Submodel in the context of maintenance as a whole and its connections to other existing and potential Submodels
Furthermore, it is important to understand that the aforementioned predicted useful lifetime of an asset in the sense of predictive maintenance is not static. Rather it depends on the concrete use of the asset in a specific process environment. In that regard, this prediction is impacted by the constant changes of the process values, which cause wear and tear to the asset.

Central element is the provisioning of properties [5], ideally interoperable by the means of dictionaries such as ECLASS and IEC CDD (Common Data Dictionary). The purpose of this document is to make selected specifications of Submodels in such manner that information about assets can be exchanged in a meaningful way between partners in a value creation network.
Target is the cross-manufacturer exchange of technical documentation as information for use. The technical documentation should be transferable as intelligent information, i.e., the content should be modular, semantically rich, and exchangeable in different media formats as well as in media-specific compilations.
Compared to the conventional document-based exchange of technical documentation, the aim is to enable dynamic, structured, and intelligent transmission that can provide content for users in a user-oriented form. This includes usage scenarios in Industry 4.0, websites, mobile apps, portal applications and display on HMIs. The relevant information should be able to be displayed to the user at the right time, in the right context, in the right format, and on the right end device.
The intended use-case is the provisioning of a standardized property structure to exchange and integrate intelligent information between companies, the departments of a company and information from different sources in general.
This concept can serve as a basis for standardizing the respective Submodel. The conception is based on existing norms, studies of common practices at enterprises, directives and standards so that a far-reaching acceptance can be achieved.

Provision of 3D Models

02026

Published

The general Scope of the specification IDTA SMT 020026 “Provision of 3D Models” with the Submodel “Models3D” aims to provide enough meta data to find the right file, to integrate the file in the right way and to do plausibility checks. The file can be either provided within the Submodel itself or, as recommended, with a link to an online file source. This Submodel should complement the existing 3D model file formats and is not meant to replace or redefine them. Nevertheless, meta data that is seen as relevant during the exchange (provision, search, integration) of 3D models but is not harmonized across the various 3D formats will be in the scope of this Submodel. Based on the experience of different stakeholders of the working group “Provision of 3D Models”, for various reasons, there is still the demand for different 3D file formats, be it based on standards like ISO 10303 or proprietary software formats. The scope is based on the implemented use cases and might be extended in future versions of the AAS Submodel Template “Provision of 3D Models”. The [SM] “Models 3D” is suitable for Asset Administration Shells (AAS) of the kind type and instance.
In short: the scope of the SubmodelTemplate IDTA 020026 “Provision of 3D Models” with the Submodel “Models3D” is the provision of 3D Models by complementing and not redefining the existing 3D Model formats themselves.

Wireless Communication

1.0

Published

This document is intended to address aspects of wireless communication. The structure of this Submodel is expressed through diagrams and UML tables, clarifying its constituent elements. In addition, potential assets and usage scenarios that can benefit from the adoption of this Submodel are identified. The main objective of this Submodel is to integrate wireless industrial communication in the context of the Industry 4.0 (I4.0) framework. The approach is based on the design of a Submodel that encompasses the parameters associated with an asset with wireless communication characteristics. Such a Submodel model is configured to create a fundamental set of Submodel elements that digitally represent relevant information about the different parts that make up a wireless communication system. This Submodel incorporates parameters relevant to various wireless communication technologies and assets. The underlying idea is that the Submodel has a generic character, allowing its application to different technologies and different types of assets. Therefore, some Submodel parameters may be more or less relevant depending on the technology and asset that will be modelled. In order to make the Submodel more specific, the user has the possibility to expand it by adding additional parameters at the time of AAS implementation. Other Submodels targeting specific communication technologies can be standardized later based on this Submodel. The Submodel focuses on layers 1 and 2 of the ISO-OSI model. The description of aspects from layer 3 upwards are not considered in this document and should be described for other submodels, as they do not depend on the type of technology, be it wireless or wired.

Handover Documentation

02004

1.2

Published

The Submodel Handover Specification defines a standardized exchange format for information or documentation for a specific asset. The scope of this Submodel is to increase the interoperability between the parties that are exchanging asset documentation. These parties can be manufacturers of components or complete machines, or operators using these components or machines. In case a machine manufacturer sells a machine to a customer (operator), the manufacturer hands over the machine and its documentation in form of an AAS with the Submodel “Handover Documentation”. The documents provided can contain information required for e.g. correct design, installation, commissioning, spare parts stocking, operation, cleaning, inspection, maintenance, and repair. In addition, there are legal regulations that stipulate the existence of certain manufacturer documents, such as Communauté Européenne (CE) declarations of conformity, Atmosphères Explosives (ATEX) certificates, or material certificates. Besides the structure of a Submodel and the exchange format of an AAS, this Submodel standardizes the meta data that comes with the asset documentation and the classes that classify the type of the document. With these standardized meta data and classes, the asset documentation can be automatically integrated in the customer’s document management system, backend system, or any other system. The meta data as well as the classification classes of this Submodel are based on the VDI Guideline VDI 2770 Blatt 1 “Operation of process engineering plants – Minimum requirements for digital manufacturer information for the process industry” [7]. While the classification of documents according to VDI 2770 is mandatory, additional classification classes can be added.

The presented Submodel allows the interoperable provision of simulation model files for an asset via the asset administration shell. The Submodel enables this for a wide range of simulation model types and simulation purposes. It contains information about the type of model, how to use the model, and the areas of application.
The main underlying class of models for this Submodel are DAEs, models described by differential algebraic equations. However, models of other types, such as CAD, FMEA, etc., can also be described. FEM type models are not considered explicitly, they will be covered by another Submodel by interest. The models described by this Submodel may be provided in ASCII or binary form to be used with a specific simulation software (e.g. Matlab/Simulink, Virtuos, etc.), as source code (e.g. C, Modelica, etc.), or in a model exchange format such as FMI.
It describes rudimentarily the content of the model.
Assets, where you can provide simulation models via AAS, can be passive parts, active devices, subsystems, machines or even production plants. When using this Submodel template, it is requiered that the asset for which a simulation model should beprovided has an AAS. That is, if there are no AAS yet, first an asset-ID needs to be defined and an AAS created. A Submodel can then be added to this AAS.
In the first step, the Submodel supports searching and finding, as well as requesting simulation model files from manufacturers or distributors.
In further steps, the Submodel will also support the automatic integration of a model into a specific simulation environment, up to an automatic generation of an overall simulation based on structural descriptions of a system containing different components. As it is possible with e.g., the Submodel candidate for hierarchical structures enabling “Bills of Material” (BoM).

Sensor 4.0 Part1: Measurement Value

02029-1

1.0

In Review

Coming soon

The idea of Submodel Sensor 4.0 is to provide a common representation of all data around industrial sensors, including data that is generated by sensors as well as data that describes the sensor itself and its integration. Submodel Sensor 4.0 is intended as a series of Submodel templates for different aspects of sensor usage. This document as part 1 of the Submodel Sensor 4.0 series is named “Measurement Value” because it focusses on the operation of sensors as data generating devices. It provides a data model for a generic access to sensor data completely independent from the sensor’s functional and interface technology.

Time Series Data

02008

1.1

Published

In Industrie 4.0, the ubiquity of data sources and sensors and low costs of storage has resulted in increasing amounts of time series data being captured – not only during the operational phase of an asset. A time series is a series of data points in time order over a period of time. Time Series can represent raw data, but can also represent main characteristics, textual descriptions or events in a concise way. This Submodel template aims at an interoperable description of time series data in industrial automation for the complete asset lifecycle. The focus of this Submodel template is on the semantic information of time series data. The Submodel claims to integrate time series data within the AAS itself, but also from external data sources. Figure 1 shows the use cases, such as sensor data from real and virtual sensors, and their technical storage options inside or outside the AAS that were taken into account in the creation of this specification.

Service Request Notification

02010

1.0

Published

This Submodel template aims to standardize the description of a Service Request Notification that can be used to create a Service Request Notification for industrial assets, or the asset creates it via his Asset Administration Shell (AAS). These industrial assets, such as production lines, modules, infrastructure elements, and subsystems, are provided by value chain partners such as suppliers, equipment manufacturers, and system integrators. They are utilized in specific applications by industrial operators and end users.
A Service Request Notification is a request for a service to be performed, such as a maintenance, an inspection, or a return. The notification entry can be made by Asset Administration Shell (AAS), via a service dashboard, service portal or even through the customer service department by phone.
The Service Request Notification can be considered as a „call for help“, which, if the business partner responds to it, triggers the further service process.
The objective of the Submodel template is to define and standardize the Service Request Notification, including its content (properties, operations, etc.) and structure. Additionally, service types are defined.
The objective of this Submodel is to enable the interoperable exchange of these notifications between Asset Administration Shells, and the IT systems of various value creation partners.

Hierarchical Structures enabling Bills of Material

02011

1.1

Published

This Submodel Template aims to provide hierarchical structures applicable to industrial equipment in an interoperable manner. For this primarily Entities and Relationship Elements of the AAS Metamodel are used.
This industrial equipment, for example production lines, modules and sub systems, are provided by partners in the value chain, such as suppliers, equipment manufacturers and systems integrators and used in specific applications by industrial operators and end users, both in factory as also process automation. Industrial equipment can be composed of subsystems down to material and component level, can include produced products and can be described on type or instance level.
The AAS contains Submodels that cover aspects of the assets among their life cycle. Already in the design phase, assets are composed and aggregated into newly created hierarchical structures.
Typically, assets have their own AAS (Entity with entityType “SelfManagedEntity“), but it is possible that an Asset has no AAS and is represented by a co-managed Entity.
Since nesting of AAS and Submodels is forbidden by the metamodel, this Submodel is intended to provide a description of the internal structure of an asset. It shall allow the consumer of an AAS to identify assets and their corresponding entities and find their respective AAS if they exist. The Submodel serves as an index, pointing to Assets (described as co- or self-managed entities) and AAS in a distributed network capable of transcending the limits of a single organization.
Instances of this Submodel Template shall be the authoritative source for hierarchical structures within an AAS during all lifecycle phases. Complementing information about each asset and their own lifecycle phase is enabled to be discoverable into the n-th level of the hierarchy and across the whole supply chain depending on the design of the Submodel Instance.

Plant Asset Management

02019

1.0

Published

The AAS Submodel „Plant Asset Management Specification Sheet“ is a crucial tool for the procurement and documentation of Plant Asset Management (PAM) functions in industrial settings. Its scope includes establishing a clear contractual basis and documenting PAM functions. These functions can range from special control system functions to add-on parts on production equipment or enabled functions within the equipment. The Submodel ensures a well-defined contractual basis during procurement, minimizing misunderstandings and improving efficiency. It standardizes requirements, specifications, and expectations related to PAM functions, allowing all stakeholders, such as producers, control system manufacturers, and equipment manufacturers, to have a shared understanding.
Furthermore, the Submodel serves as documentation for PAM functions, capturing vital information. It includes detailed descriptions of function blocks, sensors, and monitoring devices, ensuring a comprehensive record of PAM functionalities. This documentation facilitates troubleshooting, maintenance, and modifications. In addition, the Submodel supports the engineering process, which often involves multiple stakeholders and departments. It acts as a central reference, aligning efforts and fostering collaboration between departments such as procurement, operation, maintenance, sales, and engineering. The Submodel promotes transparency and manages dependencies in engineering PAM functions.
The Submodel also aids decision-making throughout the PAM functions‘ lifecycle. It provides information for informed decisions regarding maintenance, upgrades, and component replacement. It also assists in evaluating compatibility and integration of new PAM functions into existing systems. This is crucial for managing complex industrial environments with interconnected systems.
The management of online and historical data for a specific PAM function is not within the scope of this Submodel. This is because such data may contain highly detailed and specific information that is beyond the level of specification covered here. Additionally, the management of this data may be better suited for a separate AAS Submodel focused on general condition monitoring, which is not addressed in this particular Submodel. The primary focus of this Submodel is to establish a contractual basis, document PAM functions, and support the engineering process, rather than delving into the intricacies of online and historical data management.

Published

The scope of this Submodel is the definition of type-specific information of a Control Component (CC) into an AAS. Together with its counterpart, the CCInstance Submodel (IDTA 02016), both Submodels aim to establish templates to ensure a uniform structure. The use of these templates allows the development of manufacturer- and domain-independent control concepts and facilitates the exchange of process information with other Submodels. Additionally, it allows the use of standardized call and monitoring sequences, as well as standardized description of its services, endpoints, error-codes, etc.

Information Model for P&I Diagrams based on DEXPI Standard

02012

1.0

Published

The engineering of a process plant is a complex multi-disciplinary and multi-organizational process involving exchange of a vast number of (semi-)standardized artifacts like diagrams, drawings, tables, certificates, and other documents.
One core artifact which is created and extended during the engineering process is the Piping & Instrumentation Diagram (P&ID) providing among others a good balance of abstraction between the physical layout of the plant (i.e., used equipment and piping connections) and its representation within the automation domain (i.e., signal types, tag names, logical connections between sensor and actuators). Due to this fact P&IDs are long-living artifacts which are frequently used during the whole plant’s lifecycle beyond the engineering phase [7].
Even though most engineering artifacts are created digitally, they are not necessarily exchanged in a machine-readable format. The lack of a machine-readable representation of engineering artifacts (including P&IDs) hinders the digital transformation and can be a show-stoper for digital use-cases due to high costs of creation of a machine-readable P&ID representation.
Efforts to create a standardized machine-readable exchange format for P&ID are made by the DEXPI working group of DECHEMA including of operators from multiple verticals, engineering companies, software tool vendors and research institutes. DEXPI [8] is an UML-Model implemented using an XML-based P&ID exchange format including multiple aspects of plant design like piping topology and its graphical representation, instrumentation structure, tag names. DEXPI is an open industrial standard aiming for a broad usage across industrial domains.
Due to the paramount role of P&ID during whole plant’s lifecycle, the importance of DEXPI has been identified by the Industry 4.0 community. Inclusion of DEXPI models into a standardized lifecycle information container – the Industry 4.0 Asset Administration Shell (AAS) – would facilitate links between different disciplines, organizations and industry domains. Mapping of DEXPI models to the AAS by defining an AAS Submodel template is governed by Industrial Digital Twin Association (IDTA) where a respective working group was founded in 2022. The group consists of representatives of the DEXPI working group, oil and gas industry, engineering and procurement companies, automation equipment suppliers, and research institutes.
