Overview

EN 61987-24-2:2017 is a European Standard under the CENELEC (CLC) framework, directly adopting IEC 61987-24-2. The standard addresses the industrial-process measurement and control sector, focusing on data structures and elements in process equipment catalogues. Specifically, it details the list of properties (LOPs) for valve/actuator accessories to support reliable and efficient electronic data exchange.

The document establishes a harmonized method for describing and exchanging technical properties of accessories for automated valves - such as filter regulators, limit switches, position transmitters, and solenoid valves. By standardizing both the content and structure of property lists, it enhances interoperability within and between industrial organizations, making equipment specification, engineering, procurement, and systems integration more streamlined.

Key Topics

• Operating List of Properties (OLOP):
  Defines the operational parameters and requirement-collection properties for valve/actuator accessories. It supports inquiries and quotations by collecting all relevant data points associated with accessory operation and integration.

• Device List of Properties (DLOPs):
  Provides structured lists for documenting the device-specific attributes of accessories attached to automated valves, enabling precise electronic descriptions for filter regulators, limit switches, position transmitters, and solenoid valves.

• Data Standardization and Exchange:
  Follows the general structure specified in IEC 61987-10, IEC 61987-11, and IEC 61987-21, ensuring compatibility across data systems. Properties and blocks referenced conform to the IEC 61360 series and utilize the IEC Common Data Dictionary (CDD), supporting machine-readable and human-readable formats.

• Classification and Libraries:
  Assigns unique identifiers and node IDs for each accessory LOP/DLOP within the established classification scheme, accessible through the IEC CDD. Libraries for properties and block structures are provided to assist in organizing and navigating accessory data.

Applications

EN 61987-24-2:2017 brings tangible benefits to a range of industrial-process measurement and control activities:

• Procurement and Quotation:
  Facilitates transparent, accurate, and standardized requests for quotation (RFQ) and offer comparisons by clearly defining all technical properties of valve/actuator accessories.

• Systems Integration:
  Enables efficient electronic data transfer between manufacturers, engineering companies, and end-users, reducing transfer errors and manual data entry.

• Process Equipment Catalogues:
  Ensures consistency in the structure and terminology of process equipment catalog data, improving the usability of electronic catalogues and supporting automated catalog management.

• Lifecycle Data Management:
  Enhances asset management and maintenance by providing comprehensive digitally native equipment descriptions, streamlining updates and replacements in plant systems.

• Engineering and CAE Tools:
  Supports Computer-Aided Engineering (CAE) and database-driven engineering environments by offering standardized, machine-readable datasets for accessory specification and selection.

Related Standards

Several standards interrelate with or are referenced by EN 61987-24-2:2017, forming part of a broader digitalization framework in industrial process automation:

• IEC 61987-10: Fundamentals for constructing LOPs for process measurement and control for electronic data exchange.
• IEC 61987-11: Generic structures for measuring equipment LOPs.
• IEC 61987-21: Generic structures for automated valve LOPs.
• IEC 61360 series: Standard data element types with classification schemes for electric components.
• IEC 60534-1 & IEC 60534-7: Terminology and data sheets for control valves.
• IEC 61987-22: LOPs for valve body assemblies.
• IEC 62424: Data exchange between P&ID tools and engineering systems.
• ISO 80000-1: General quantities and units.

By aligning with these standards, organizations ensure that their process catalogue data remains compatible and supports the latest advances in industrial IT solutions, engineering workflows, and electronic data interchange (EDI) requirements.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61987-24-2 has been prepared by subcommittee 65B: Measurement and control devices, of IEC technical committee 65: Industrial-process measurement, control and automation. The text of this International Standard is based on the following documents: CDV Report on voting 65B/1036/CDV 65B/1065/RVC
