TS EN 61987-24-1
Industrial-process measurement and control - Data structures and elements in process equipment catalogues - Part 24-1: Lists of Properties (LOPs) of positioners and I/P converters for electronic data exchange
This part of IEC 61987 provides
• Operating Lists of Properties (OLOPs) for the description of the operating parameters and
the collection of requirements for valve/actuator accessories, that can be used for every
valve/actuator accessory,
• Device Lists of Properties (DLOPs) for positioners and I/P converters.
The structures of the OLOP and the DLOPs conform to the general structures defined in
IEC 61987-11 and IEC 61987-21 as well as to the fundamentals for the construction of LOPs
defined in IEC 61987-10. The DLOPs conform additionally with the terms defined in
IEC 60534-7.
Libraries of properties and of blocks used in the LOPs are listed in Annexes A and B
respectively.

About This Item
TS EN 61987-24-1 defines Lists of Properties for positioners and I/P converters used in industrial-process measurement and control. Its focus is the data model that makes these devices describable for electronic data exchange in process equipment catalogues, so that technical information can be presented in a common, structured form for selection, comparison, and digital exchange rather than as manufacturer-specific descriptions.
Property lists for valve and actuator accessories
The standard provides Operating Lists of Properties (OLOPs) for describing operating parameters and collecting requirements for valve/actuator accessories, and Device Lists of Properties (DLOPs) specifically for positioners and I/P converters. In general technical terms, a positioner is used to improve the accuracy with which a final control element reaches and holds its commanded position, while an I/P converter transforms an electrical control signal into a pneumatic pressure signal. Because these devices influence control performance, response, and integration with the automation system, their catalogue data needs a precise and consistent structure.
Alignment with the IEC 61987 family
The OLOP and DLOP structures conform to the general frameworks defined in IEC 61987-11 and IEC 61987-21, as well as to the principles for constructing LOPs given in IEC 61987-10. The DLOPs also conform to the terminology defined in IEC 60534-7. Annexes list the property libraries and the blocks used in the LOPs, supporting consistent, machine-readable data exchange across equipment catalogues and related engineering tools.
