This part of IEC 61987 provides:
• a characterisation 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 IEC 61987-11. For instance, the OLOP and DLOP for flow transmitters with blocks and
properties are to be found in IEC 61987-12.
