IEC 61987-32:2024 provides an Operating List of Properties (OLOP) for describing the operating parameters and collecting requirements for I/O modules, as well as a Device List of Properties (DLOP) for detailing various types of I/O modules.

The structures of the OLOP and DLOPs align with the general structures defined in IEC 61987-11 and comply with the fundamental principles for constructing Lists of Properties (LOPs) as outlined in IEC 61987-10.

Additional aspects, beyond the OLOP, that are necessary for various electronic data exchange processes and described in IEC 61987-10 and IEC 61987-11, are published in IEC 61987-92.

The locations of the property libraries and blocks used in the relevant LOPs are provided in Annex C and Annex D.
