IEC 61987-21-2015 工業(yè)過(guò)程測量和控制--加工設備目錄中的數據結構和元素--第21部分:用于電子數據交換的自動(dòng)閥門(mén)的屬性列表(LOP)--通用結構 Industrial-process measurement and control - Data structures and elements in process equipment catalogues - Part 21: List of Properties (LOP) of automated valves for electro

This part of IEC 61987 provides
• a characterization for the integration of automated valves, including control valves, automated on/off-valves and process regulators, in the Common Data Dictionary (CDD);
• generic structures in conformance with IEC 61987-10 for Operating Lists of Properties (OLOPs) and Device Lists of Properties (DLOPs) of final control elements.
The generic structures for the OLOP and DLOP contain the most important blocks for final control elements. 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 part of IEC 61987. For instance, the OLOP and DLOP for globe valves and rotary valves are found in IEC 61987-22.
NOTE Within the classification (see also Figure 1), “final control element” has only the specializations automated valves and process regulators. In practice there are other specializations that are not considered in this standard.dition 1.0 2015-09 INTERNATIONAL STANDARD NORME INTERNATIONALE Industrial-process measurement and control – Data structures and elements in process equipment catalogues – Part 21: List of Properties (LOP) of automated valves for electronic data exchange – Generic structures Mesure et commande dans les processus industriels – Structures de données et éléments dans les catalogues d’équipement de processus – Partie 21: Liste de propriétés (LOP) des vannes automatisées pour l'échange
