TS EN 61987-22

TS EN 61987-22 defines a common property structure for electronic data exchange of valve body assemblies and process regulators used in industrial-process applications. It belongs to the IEC 61987 family of catalogue-data standards and uses the Lists of Properties (LOP) approach to present technical characteristics in a consistent, machine-readable way.

How OLOP and DLOP complement each other

The standard provides two main forms of property lists: Operating Lists of Properties (OLOP) and Device Lists of Properties (DLOP). OLOP is intended for describing operating parameters and the collection of requirements relevant to valve body assemblies and process regulators. DLOP is used to describe various types of valve body assemblies and process regulators as devices. In practical terms, this separation helps distinguish how equipment is expected to operate from what the equipment is, which is important when catalogues are exchanged between different engineering tools or organisations.

Technical context and related terminology

The structures of the OLOP and DLOP follow the general LOP framework defined in IEC 61987-11 and IEC 61987-21, as well as the principles for building LOPs in IEC 61987-10. The DLOPs also align with terms defined in IEC 60534-7. Annex A lists the property libraries used in the LOPs, and Annex B lists the blocks. More broadly, standards of this kind support interoperable product data exchange by giving catalogues a shared vocabulary and a shared data organisation, which improves consistency in selection, comparison and integration workflows.

• Provides structured property lists for valve body assemblies and process regulators in electronic data exchange.
• Separates operating parameters from device description through OLOP and DLOP models.
• Aligns its structure with the IEC 61987 LOP framework and terminology from IEC 60534-7.
• Includes annexes listing the property libraries and blocks used in the LOPs.
