LKM Series Modbus RTU to IEC62056-21 Gateway are designed to be used with electricity meters that communicate in IEC62056-21 standard. The meters that support the IEC62056-21 standard have read out tables that have several data such as import energy, export energy, phase voltages, and currents. LKM Series Modbus RTU to IEC62056-21 Gateway automatically reads those values and maps to Modbus registers. Field devices or software systems can easily read data over Modbus RTU protocol so that energy meter reading can easily be integrated to field automation systems without need of IEC6056-21 protocol implementation.
