This part of IEC 61987 provides
• Operating Lists of Properties (OLOP) for the description of the operating parameters and the collection of requirements for valve body assemblies and process regulators,
• Device Lists of Properties (DLOPs) for the description of various types of valve body assemblies and process regulators.
The structures of the OLOP and the DLOP 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 terms defined in IEC 60534-7.
Libraries of properties and of blocks used in the LOPs are listed in Annexes A and B respectively.dition 1.0 2015-09 INTERNATIONAL STANDARD NORME INTERNATIONALE Industrial-process measurement and control – Data structures and elements in process equipment catalogues – Part 22: Lists of Properties (LOPs) of valve body assemblies for electronic data exchange Mesure et commande dans les processus industriels – Structures de données et éléments dans les catalogues d’équipement de processus – Partie 22: Listes de propriétés (LOP) des ensembles de corps de vannes pour l’échange é
