IEC 62656-5:2017

Overview

IEC 62656-5:2017 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies a method for representing and transferring activity descriptions through spreadsheets. This standard introduces the Parcellized Activity Model (PAM), a specialized form of the Parcellized Ontology Model (POM) defined in Part 1 of the IEC 62656 series. The PAM focuses on describing activities and their relations in a tabular ontology format, enabling clear representation of complex processes, organizational functions, and service collections.

The standard defines how activities-ranging from entire enterprises to discrete events or processes-interact with each other by exchanging physical or non-physical entities such as information, materials, or objects. A key feature of IEC 62656-5:2017 is its method for uniquely identifying activities and sequencing them properly, supporting comprehensive process modeling and management.

Key Topics

• Parcellized Activity Model (PAM): A tabular ontology representation used to model activities and their relationships in a structured and standardized way.
• Activity Description Interface: Enables users to describe activities, subactivities, and their interactions in a spreadsheet format conducive to data interchange.
• Activity Identification: The method provides unique identifiers for activities and sequences for homologous happenings to ensure clarity and prevent ambiguity in activity records.
• Flows and Relations: Defines the flows of information, objects, or materials exchanged between activities through relations and arrows that represent interactions.
• Extended Semantics: Includes advanced modeling constructs such as conjunction, disjunction, selection nodes, and decision trees to represent complex activity scenarios beyond traditional methods.
• Integration with IDEF0: Supports graphical representation corresponding to IDEF0 notation, a widely used process modeling standard, enabling interoperability between tabular and diagrammatic activity descriptions.
• Meta-Properties and Formula Delegation: Establishes meta-properties for detailed activity properties and supports delegated formula interpretation to enhance semantic richness.
• International Concept Identifier (ICID): Facilitates globally unique identification of concepts to promote consistency and interoperability in multi-organizational environments.

Applications

IEC 62656-5:2017 provides a practical framework for industries and organizations aiming to standardize the description and exchange of activity-based data. Its applications include:

• Enterprise Process Modeling: Helps businesses document, analyze, and improve workflows, enabling clearer understanding and optimization of operational structures.
• Manufacturing Operations: Supports production management by modeling production processes, material flows, and service interfaces, aiding in integration with standards such as IEC 62264.
• Service-Oriented Architecture: Models interactions and exchanges within service networks, facilitating coordination and data exchange across organizational boundaries.
• Information Systems Integration: Enables consistent activity data exchange between different IT systems by leveraging spreadsheet-based ontology registers.
• Business Process Interoperability: Enhances collaboration between partners by providing a standardized interface for activity description, improving synchronization and reducing misunderstanding.
• Compliance and Documentation: Assists in maintaining documentation consistent with international standards for quality management, auditing, and regulatory compliance.

Related Standards

• IEC 62656 Series: The broader series addresses standardized ontology register and transfer methods, where Part 1 defines the generic Parcellized Ontology Model (POM) foundational for this part.
• IEC 62264: International standard for enterprise-control system integration, which complements PAM by defining production operations management models described using IEC 62656-5.
• IDEF0: A functional modeling methodology used for describing manufacturing functions, processes, and systems. IEC 62656-5’s alignment with IDEF0 enables visualization of activity models.
• ISO/IEC 19510 (BPMN): Business Process Model and Notation standard for process modeling that may be integrated or mapped with the ontology models described in IEC 62656-5.
• ISO 15926: For process plants data integration, which shares the goal of ontology-based standardized data exchange and could intersect with IEC 62656 use cases.
