IEC 61987-32:2024

Overview

IEC 61987-32:2024 is a crucial international standard published by the International Electrotechnical Commission (IEC) focusing on data structures and elements in process equipment catalogues. Specifically, Part 32 addresses the Lists of Properties (LOP) for Input/Output (I/O) modules used in electronic data exchange within industrial-process measurement and control systems.

This standard provides two main components: an Operating List of Properties (OLOP) for describing the operational parameters and requirements of I/O modules, and a Device List of Properties (DLOP) for characterizing a variety of I/O module types. The structures align with the foundational models detailed in IEC 61987-10 and IEC 61987-11, ensuring interoperability and consistency across process control equipment catalogues.

Key Topics

• Operating List of Properties (OLOP): Defines a structured and standardized list of operational properties for I/O modules, facilitating their description in various electronic data exchanges.
• Device List of Properties (DLOP): Specifies a comprehensive set of properties to describe different I/O module types, including input modules, output modules, and combined units.
• Data Structure Alignment: The OLOP and DLOP structures strictly follow the generic frameworks established in IEC 61987-10 (fundamentals) and IEC 61987-11 (lists of properties), supporting harmonized data handling.
• Property and Block Libraries: Annexes C and D contain detailed libraries of properties and blocks utilized in the LOPs, serving as authoritative resources for consistent device characterization.
• Integration with Related Standards: IEC 61987-32 complements other parts of the IEC 61987 series, such as IEC 61987-92, which addresses additional aspects needed for different electronic data exchange processes.

Applications

IEC 61987-32:2024 is designed for use in:

• Industrial Automation and Control Engineering: Enabling engineers and system integrators to accurately specify and exchange I/O module data across design, procurement, and maintenance workflows.
• Manufacturers and Suppliers: Facilitates a uniform method to describe product characteristics in electronic catalogues or databases, improving communication with customers.
• Enterprise Systems Integration: Supports seamless data exchange between disparate IT systems within organizations, reducing duplication and improving data consistency.
• Process Equipment Specification: Assists in standardizing the requirements collection and characterization of I/O modules, streamlining device selection and configuration.
• Interoperability in Process Measurement and Control: Enhances compatibility between devices and electronic systems by adopting common data structures for I/O modules.

This standardized approach benefits stakeholders by reducing errors, optimizing workflows, and ensuring clear communication throughout the lifecycle of process equipment deployment.

Related Standards

IEC 61987-32 is part of the broader IEC 61987 series, which defines data structures for process equipment catalogues:

• IEC 61987-10: Fundamentals of Lists of Properties (LOPs) – establishes general structure elements and data models essential for constructing LOPs.
• IEC 61987-11: Generic Structure for Operating and Device Lists of Properties (OLOPs and DLOPs) – provides the framework on which specific device-type LOPs are based.
• IEC 61987-31: Lists of Properties for Infrastructure Devices – covers classification and LOPs for devices found in switching and control rooms.
• IEC 61987-92: Additional Aspects for Electronic Data Exchange Processes – publishes other necessary components and guidelines beyond OLOP for diverse data exchange scenarios.

Utilizing these interconnected standards allows for holistic and consistent implementation of electronic data exchange processes in industrial-process measurement and control environments.
