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.
