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.
