LKM Series Modbus RTU to IEC62056-21 Protocol Gateway are designed to be used with electricity meters that
communicate in IEC62056-21 standard. The meters that support IEC62056-21 standard has read out tables that has
several data such as import energy, export energy, phase voltages and currents. LKM Series Modbus RTU to
IEC62056-21 Protocol 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 or monitoring systems without need of IEC6056-21 protocol implementation.
LKM series can read meters with auto baud changes or fixed baud rates and supports up to 10 meters on RS485 bus.
LKM614 is especially designed for EMH LZQJ-XC meters and it is direct replacement for Variomod XC modules.

2. Hardware Features
LKM Series Modbus RTU to IEC62056-21 Protocol Gateway has 2-way communication. One side connected directly
or via optical probe to read electricity meter with IEC62056-21 protocol, other side can be connected to a field
device such as PLC or RTU or serial device server connected to an automation software system that can read
Modbus RTU devices.
There are standalone versions and also plug and play version for EMH LZQJ-XC meters.
