IEC 61987-31:2022

Overview

IEC 61987-31:2022 is an international standard developed by the International Electrotechnical Commission (IEC) under technical committee IEC TC 65. This standard focuses on industrial-process measurement and control with a specific emphasis on data structures and elements used in process equipment catalogues. Part 31 of the IEC 61987 series provides generic structures for Lists of Properties (LOPs) of infrastructure devices, facilitating seamless electronic data exchange.

IEC 61987-31:2022 establishes the foundational characterization and integration framework for infrastructure devices within the Common Data Dictionary (CDD). It defines generic blocks for Operating Lists of Properties (OLOPs) and Device Lists of Properties (DLOPs), ensuring consistent descriptions for infrastructure devices across various industrial process control systems. This standard complements other parts of the IEC 61987 series that address specific equipment types and their unique properties.

Key Topics

• Generic Structural Framework: Defines reusable block structures for OLOPs and DLOPs, facilitating uniform descriptions across a broad range of infrastructure devices.
• Characterization Scheme: Describes the method for categorizing infrastructure devices to ensure consistency in identification and data handling.
• Operating List of Properties (OLOP):
  • Covers device operating conditions including environmental, installation, and power supply considerations.
  • Focuses on device location specifics such as process criticality and area classification.
• Device List of Properties (DLOP):
  • Details device identification, application scope, functional design, dependability, and input/output properties.
  • Describes digital communication interfaces and performance metrics under reference conditions.
  • Includes physical and mechanical specifications such as overall dimensions, weight, structural design, and explosion protection.
  • Addresses operability features including configuration, parametrization, operation, and diagnostic capabilities.
  • Lists certifications, approvals, and component part identifications relevant to device compliance.
• Cardinality and Polymorphism: Supports flexibility in property definitions to accommodate multiple instances and device variants.
• Composite Devices: Guidance on managing devices composed of several infrastructure sub-components.
• Normative Integration: Aligns structures and definitions with IEC 61987-10 and IEC 61987-1 to maintain coherence within the IEC 61987 series.

Applications

IEC 61987-31:2022 is primarily aimed at professionals and organizations involved in industrial automation, process measurement, and control systems, including:

• Manufacturers of infrastructure devices seeking standardization in device cataloguing and data exchange.
• System Integrators who require harmonized device data structures to facilitate integration with control systems and enterprise applications.
• Automation Engineers tasked with selecting, configuring, and maintaining infrastructure devices within plants.
• Digitalization Experts working on Industry 4.0 initiatives that depend on standardized electronic data exchange for interoperability.
• Software Developers creating cataloguing, asset management, or digital twin solutions that leverage standardized device property models.
• Certification Bodies referring to standardized property definitions for compliance verification.

The implementation of IEC 61987-31 enhances data quality, reduces integration complexity, and accelerates device interoperability across multiple stakeholders in the industrial ecosystem.

Related Standards

IEC 61987-31:2022 is part of the larger IEC 61987 series, which covers data structures and elements in process equipment catalogues. Related parts include:

• IEC 61987-10: Defines general rules and generic structures for equipment catalogues and Operating Lists of Properties (OLOPs).
• IEC 61987-1: Provides overarching device description and property modeling applicable across the series.
• IEC 61987-32: Details OLOPs and DLOPs specifically for Input/Output modules.
• Other parts addressing specific infrastructure equipment types and their unique data properties.

By adhering to these interconnected standards, organizations achieve consistent, interoperable device data models that underpin efficient process automation and control.
