BS EN 61987-11:2017

What is BS EN 61987-11 – Measuring equipment for electronic data exchange about?  

BS EN 61987-11 is the 11th part of the IEC 61987 multi-series that discusses industrial-process measurement and control. 

BS EN 61987-11 provides: 

• A characterization of industrial process measuring equipment (device type dictionary) for integration in the Common Data Dictionary (CDD), and 
• Generic structures for operating lists of properties (OLOP) and device lists of properties (DLOP) of measuring equipment in conformance with IEC 61987-10 

The generic structures for the OLOP and DLOP contain the most important blocks for process measuring equipment. Blocks pertaining to a specific equipment type will be described in the corresponding part of the IEC 61987 standard series. Similarly, equipment properties are not part of BS EN 61987-11. For instance, the OLOP and DLOP for flow transmitters with blocks and properties are to be found in BS EN 61987-12. 

Who is BS EN 61987-11 – Measuring equipment for electronic data exchange for? 

BS EN 61987-11 on industrial-process measurement and control is useful for: 

• Manufacturers of measuring equipment 
• Manufacturing units that use electronic data interchanging systems 
• Suppliers of electronic process measurement and control equipment 

Why should you use BS EN 61987-11– Measuring equipment for electronic data exchange?  

The exchange of product data between companies, business systems, engineering tools, data systems within companies and, in the future, control systems (electrical, measuring and control technology) can run smoothly only when both the information to be exchanged and the use of this information has been clearly defined. 

BS EN 61987-11 specifies the generic structure for operating and device lists of properties (OLOPs and DLOPs). BS EN 61987-11 lays down the framework for further parts of IEC 61987 in which complete LOPs for device types measuring a given physical variable and using a particular measuring principle will be specified.  

The LOPs specified in BS EN 61987-11 describe at the generic level: 

• The operating conditions of the measuring equipment 
• The ambient conditions at the measuring point 
• The performance of the measuring equipment 
• The metrological, mechanical and electrical features of the measuring equipment 
• The compliance of the measuring instrument to specific industrial requirements 

The generic structure may also serve as a basis for the specification of LOPs for other industrial-process control instrument types such as control valves and signal processing equipment. 

What’s changed since the last update? 

BS EN 61987-11:2017 replaces BS EN 61987-11:2012. BS EN 61987-11:2017 includes the following significant technical changes with respect to BS EN 61987-11:2012: 

• The classification in Table A.1 has been amended to reflect the changes in the classification scheme of process measuring equipment in the CDD due to the development of IEC 61987-14, IEC 61987-15 and IEC 61987-16 
• Annex A has become “informative”
