Describes:- - operating list of properties (OLOP) for the description of the operating parameters and the collection of requirements for level measuring equipment, and - device lists of properties (DLOPs) for the description of a range of level measuring equipment types.

This part of IEC 61987 provides

• operating list of properties (OLOP) for the description of the operating parameters and the collection of requirements for level measuring equipment, and

• device lists of properties (DLOPs) for the description of a range of level measuring equipment types.

The structures of the OLOP and the DLOPs correspond to the general structures defined in IEC 61987-11 and agree with the fundamentals for the construction of LOPs defined in IEC 61987-10.

Aspects other than the OLOP, needed in different electronic data exchange processes described in IEC 61987-10, will be published in IEC 61987-921.

The locations of the libraries of properties and of blocks used in the LOPs concerned are listed in the Annexes C and D.
