Interface Classes
In DLMS/COSEM, all the data in electronic meters and devices are represented by means of attribute values. Any real world thing can be described by attributes; methods allow operations to be performed on the attributes. Attributes and methods constitute an object. The first attribute in any object is the logical_name. It is one part of the identification of the object. Objects that share common characteristics are generalized as an interface class with a class_id. Instantiations of an interface class are called COSEM objects. IEC 62056-62 defines 19 interface classes for COSEM object model.

Famous quotes containing the word classes:
“Of all reformers Mr. Sentiment is the most powerful. It is incredible the number of evil practices he has put down: it is to be feared he will soon lack subjects, and that when he has made the working classes comfortable, and got bitter beer into proper-sized pint bottles, there will be nothing left for him to do.”
—Anthony Trollope (1815–1882)
