LKM Series Electricity Meter Protocol to Modbus Protocol Gateways
LKM Series Electricity Meter Protocol to Modbus Protocol Gateways
LKM Series Electricity Meter to Modbus Protocol Gateways are designed to be used with electricity meters that communicates in IEC62056-21 or P1 Companion Standard. The meters that supports IEC62056-21 and P1 Companion Standard has read out tables that has several data such as import energy, export energy, phase voltages and currents. LKM Series Electricity Meter to Modbus Protocol Gateways automatically reads that values and maps to Modbus registers.
Field devices or software systems can easily read data over Modbus RTU or Modbus TCP protocol based on device model so that energy meter reading can easily be integrated to field automation systems without need of IEC6056-21 protocol or P1 Companion Standard implementation.

LKM Series 868MHz LoRaWAN Meter Reader with Electricity Meter Protocol to Modbus Protocol Gateways can read IEC62056-21 Energy Meters and convert its data to Modbus Registers so that field devices or remote applications can meter data via Modbus TCP. Meter data will be sent to LoRaWAN Server through LoRaWAN Gateway in user defined periods. Meter data can also be sent to MQTT Server simultaneously. OBIS codes of read meters are fully definable by end user.
Typical applications: Automated Meter reading, Telemetry, Energy Management…
