IEC62056-21 DLMS Meter Driver
IEC 62056-21 (DLMS) driver for Niagara allows it to establish connection to the meter, discover all its data points with OBIS identifiers and then periodically read their values. That could be a simple and effective way to get real-time and historical values (kWh, kW, kVA, kVAr, V, I, pF etc.) from the main utility electrical meters into a building management system or an energy monitoring system. These values, along with sub-metering values retrieved from Modbus meters, can then be analyzed, shown on dashboards, used for cost prediction and building performance metrics.

IEC 62056-21 is a communication protocol often used by energy suppliers in their energy meters – mostly for electricity, but also for thermal and gas meters (as per EN 1434-3 standard). This protocol is included in IEC 62056 – family of standards maintained by International Electrotechnical Commission for electricity metering data exchange. It is a part of the “smart grid” suite of protocols and it is included into DLMS/COSEM specification.
IEC 62056-21 electrical meters usually are different from 96x96 and DIN-rail electrical meters with Modbus protocol. Utility meters are bigger in size, have a restricted access to configuration parameters and very limited user interface – they often have just a single button to switch between few values on the screen. Instead they are equipped with an optical probe interface, allowing energy suppliers to connect to the meters in a fast and safe manner temporarily.
Key features
