ISO/TS 29002-10: Industrial Automation Systems — Data Model for Parts Libraries
A technical specification defining the data model structure for industrial automation component and parts libraries
ISO/TS 29002-10 is a Technical Specification within the 29002 series that defines a comprehensive data model for industrial automation systems parts libraries. This standard provides a formalized structure for representing component characteristics, classifications, and relationships in a machine-readable format, enabling seamless exchange of product data across different engineering platforms, supply chain systems, and enterprise applications. The data model serves as the semantic backbone for organizing and retrieving component information throughout the product lifecycle, from initial design through procurement, manufacturing, and field service.
The data model defined in ISO/TS 29002-10 is expressed in the EXPRESS data modeling language (ISO 10303-11), the same language used by the STEP (Standard for the Exchange of Product Model Data) family of standards. This ensures compatibility with existing PLM infrastructure.
1. Data Model Architecture and Core Concepts
The ISO/TS 29002-10 data model is built around three core architectural layers: the dictionary model, the component characteristics model, and the classification model. The dictionary model provides a framework for defining terms, their definitions, and their relationships in a controlled vocabulary. The component characteristics model defines how individual properties — such as dimensions, material grades, performance ratings, and environmental limits — are structured and associated with component classes. The classification model establishes hierarchical taxonomies that organize components into families and subfamilies based on functional and physical attributes.
At the heart of the data model is the concept of an item class, which represents a category of components sharing common characteristics. Each item class is associated with a set of properties (called “data element types” in ISO terminology), and each property has defined data types, units of measure, and value ranges. The model also supports complex constraints such as dependency rules (e.g., “if thread size is M20, then nominal diameter shall be 20 mm”) and conditional property requirements.
One of the key strengths of the ISO/TS 29002-10 data model is its support for multiple languages. Each term in the dictionary can have definitions, names, and descriptions in multiple languages, making it suitable for global engineering organizations operating across linguistic boundaries.
2. Implementation Guidance for Engineering Systems
Implementing ISO/TS 29002-10 in an industrial automation context requires careful mapping between the abstract data model and concrete database schemas or API structures. The following table summarizes the mapping between ISO/TS 29002-10 model elements and typical implementation artifacts:
| ISO/TS 29002-10 Model Element | EXPRESS Entity | Typical Implementation |
|---|---|---|
| Item Class | item_class | Database table or OOP class for component category |
| Property / Characteristic | property | Column definition with data type, unit, constraints |
| Property Value | property_value | Cell value in parts database, XML element, JSON field |
| Classification Hierarchy | class_hierarchy | Parent-child table relationship or nested object structure |
| Unit of Measure | unit | Enumeration or reference table (SI, imperial, custom) |
| Constraint Rule | constraint | CHECK constraint, validation trigger, or business rule engine |
| Document Reference | document | URL, file path, or document management system identifier |
For practical deployment, the standard recommends using an intermediate representation format such as ISO 10303-21 (STEP physical file) or XML Schema Definition (XSD) for data exchange between systems. Many organizations implement the model using a relational database with a front-end application that provides search, browse, and data entry capabilities. The EXPRESS-defined schema can be compiled into a target schema using tools such as STEP Tools, EDMdeveloper, or open-source EXPRESS parsers. Choosing the right deployment approach depends on the existing infrastructure, technical capabilities, and integration requirements of the organization, as well as the scale and complexity of the component catalog being managed.
When implementing the ISO/TS 29002-10 data model, pay close attention to the definition of mandatory versus optional properties. Misclassifying an optional property as mandatory can lead to unnecessary data entry burdens, while making a critical property optional may result in incomplete component specifications that compromise downstream engineering analysis.
3. Integration with PLM and ERP Systems
The ISO/TS 29002-10 data model is designed to facilitate integration between Product Lifecycle Management (PLM), Enterprise Resource Planning (ERP), and Supply Chain Management (SCM) systems. By providing a standardized representation of component data, the model eliminates the need for custom point-to-point mappings between each pair of systems. Instead, each system maps to the shared data model, reducing integration complexity from O(n²) to O(n).
In practice, the integration architecture typically employs a parts master database that conforms to the ISO/TS 29002-10 schema. The PLM system publishes approved component data to this database, the ERP system consumes it for procurement and inventory planning, and the SCM system uses it for supplier qualification and sourcing. This hub-and-spoke architecture ensures data consistency across the enterprise and provides a single source of truth for component information.
Without a standardized data model like ISO/TS 29002-10, engineering organizations often suffer from data silos where the same component is described differently in CAD, PLM, ERP, and procurement systems. This leads to duplicate entries, specification mismatches, and costly procurement errors — particularly for complex engineered items with multiple critical characteristics.
4. FAQs
Q: How does ISO/TS 29002-10 relate to IEC 61360 and other component data standards?
A: ISO/TS 29002-10 shares conceptual foundations with IEC 61360 (standard data element types) and ISO 13584 (PLIB — Parts Library). The standards have been harmonized to ensure interoperability, and ISO/TS 29002-10 explicitly references the Common Data Dictionary (IEC CDD) as a source of standardized property definitions.
Q: Can ISO/TS 29002-10 be used for non-electrical or non-mechanical components?
A: Yes. The data model is domain-independent and can represent any type of component or material. It has been successfully applied to fluid power components, fasteners, structural steel sections, electronic components, and even software modules.
Q: What tools are available to help implement the EXPRESS data model?
A: Several commercial tools support EXPRESS schema compilation and instance validation, including STEP Tools (ST-Developer), EDMdeveloper (Jotne), and various open-source EXPRESS toolkits. Most PLM platforms also provide built-in support for STEP and PLIB-based data models.
