248 +The gateway can as a Modbus RTU slave to run, the user can set a range of the register to write a sensor node uplink data.

251 +For example, there is a sensor node EUI is 70b3d57ed0051e22, the register start is 0xABCD and the register length is 14, which means the uplink data will be written to the register starting at 0xABCD register and the maximum write length not to exceed 14 registers.
252 +
253 +So the sensor node 70b3d57ed0051e22 uplink data will be written to the 0xABCD - 0xABE1 register.
254 +
255 +**Note: Since the length of the payload is the same for different sensor nodes if The length of the data is greater than the configuration length, the data will be replaced with FFFF.**
