Overview
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. The responsible committee is DKE/K 931 "Systemaspekte" ("System aspects") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
