Industrial-process measurement and control - Data structures and elements in process equipment catalogues - Part 41: Lists of properties (LOPs) of process analysers for electronic data exchange - Generic structures (IEC 61987-41:2025)

IEC 61987-41: 2025 provides:
• a characterization for the integration of process analysers in the Common Data Dictionary (CDD),
• generic structures for operating lists of properties (OLOP) and device lists of properties (DLOP) of measuring equipment in conformance with IEC 61987-10,
• generic structures for Dynamic Data, e.g. for condition monitoring of process analysers.
The generic structures for the OLOP and DLOP contain the most important blocks for process analysers. Blocks pertaining to a specific equipment type will be described in the corresponding part of the IEC 61987 standard series. Similarly, equipment properties are not part of this document. Thus, OLOP, DLOPs and LOPDs for selected process analysers families will be found in the IEC CDD.

IEC 61987-41: 2025 fournit:
• une caractérisation pour l'intégration des analyseurs de processus dans le Dictionnaire de données communes (CDD),
• des structures génériques pour les listes de propriétés fonctionnelles (OLOP) et les listes de propriétés d'appareil (DLOP) des équipements de mesure conformes à l'IEC 61987-10,
• des structures génériques pour les données dynamiques, par exemple, pour la surveillance des conditions des analyseurs de processus.
Les structures génériques pour l'OLOP et la DLOP contiennent les blocs les plus importants pour les analyseurs de processus. Les blocs concernant un type d'équipement spécifique sont décrits dans la partie correspondante de la série de normes IEC 61987. De même, les propriétés des équipements ne sont pas traitées dans le présent document. Ainsi, les OLOP, DLOP et LOPD pour des familles choisies d'analyseurs de processus se trouveront dans l’IEC CDD.

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 Gui
