TS EN 61987-24-3

TS EN 61987-24-3 is the part of the IEC 61987 family that organizes how flow modification accessories are described for electronic data exchange, with a particular link to automated valves and process equipment cataloguing. Its technical value lies in turning equipment information into a structured property-based format that can be exchanged consistently between engineering, procurement and automation systems.

Operating and device views of the same equipment

The standard provides an operating list of properties (OLOP) and device lists of properties (DLOPs) for flow modification accessories. In general technical terms, an OLOP is used to capture operating parameters and requirement information, while a DLOP supports identification and catalogue-style description of the device itself. This distinction matters because process equipment often needs both a functional view and a product-definition view.

Alignment with the IEC 61987 modelling framework

The LOP structures conform to the general framework defined in IEC 61987-11 and IEC 61987-21, as well as the principles for constructing LOPs in IEC 61987-10. The terminology is additionally aligned with IEC 60534-7. In practical data-management terms, this means the standard sits within a broader vocabulary and modelling system where properties and blocks are organised for consistent exchange rather than ad hoc product descriptions.

• Annex A: OLOP for operating parameters and requirement collection for automated-valve-related flow modification accessories.
• Annex B: DLOPs for the same equipment family.
• Annex C: property libraries used in the LOPs.
• Annex D: block libraries used in the LOPs.
