TS EN 61987-23

TS EN 61987-23 defines lists of properties for valve actuators used in industrial process measurement and control. Its focus is the structured electronic exchange of data for actuator description, so that operating parameters and requirement data can be captured and compared in a common catalogue-oriented format rather than as unstructured product information.

How the property structures are organised

The standard provides two main list types: OLOPs, which are used for describing operating parameters and collecting requirements, and DLOPs, which describe device data for valve actuators. In general technical terms, a List of Properties is a disciplined data model that makes products easier to identify, compare and exchange across process equipment catalogues. The structures in this part conform to the general architectures defined in IEC 61987-11 and IEC 61987-21, as well as to the LOP construction principles given in IEC 61987-10.

What this means for actuator data

A valve actuator is the drive unit that moves a valve to open, close or modulate flow. Depending on the application, actuators may be pneumatic, electric or hydraulic, and their relevant data can include operating conditions, performance-related characteristics and interface information. This standard supports that exchange by aligning the data structure used for actuator cataloguing and requirement specification, rather than by defining the actuator itself.

• OLOPs cover operating parameters and requirement collection
• DLOPs cover device properties for valve actuators
• Property and block libraries are listed in Annexes A and B
• DLOPs are additionally aligned with terms defined in IEC 60534-7
