The "last_average_value" attribute indicates the energy accumulated in the previous period, the "current_average_value" attribute indicates the energy from the current period. Register (class_id=3): just like Data, also, a multiplication factor is automatically applied and the technical units of the value are also given - the static attribute "scaler_unit".Įxtended register (class_id=4): just like Register, also, a value timestamp is associated with the value - dynamic attribute "capture_time".ĭemand register (class_id=5): Register for measuring the supply of stored energy in given periods (e.g. ![]() ) are grouped as attributes of one object, while the list of parameters is defined by the object class.ĭata (class_id=1): basic class with the value of the data entity accessible via the "value" attribute. Logically related values (measured value, value timestamp, technical units, value collection parameters. The DLMS/COSEM standard organizes the measured values as well as the configuration parameters of electricity meters and other meters into an object structure. Others define transmissions over the telephone (IEC 62056-41) and IP networks (IEC 62056-47). Some (62056-21) are designed for manual data collection using a reader (HHU - handheld unit). The set of standards defines a whole set of protocols for communication with energy meters.
