Modbus Energy Meter Arduino

I have made this connection.

Modbus energy meter arduino.

Hello all im trying to read holding register data values of energy meter through arduino mega using rs485 to ttl converter from past 1 month but i havent suceeded. The cool thing about this product is that it has an rs485 modbus interface an industrial standard communication protocol which makes talking to an arduino. And i have an problem with communication of this module with power meter inepro pro 1mod over modbus protocol i want for example read an l1 voltage value which i know from the manual page 24 25 that this value is stored in read holding register with adrress 5002 i should communicate with these paramaters. In order to measure the electrical energy consumption we chose to use the finder energy meter since it is designed for din rail use and fits perfectly in the main cabinet of our house.

Reading energy meter data through modbus using arduino. Read voltage from eastron sdm230 modbus smart energy meter with modbus protocol. In this video i give a quick overview of the eastron sdm120 energy meter show the main features setting up the device on modbus for slave id and baud an. You don t have to care about the register address if you don t get any response.

November 27 2019 10 49am. 3 speed 2400. Dds238 1 zn modbus energy meters from arduino esp8266 avr e nina dds238 energy meter. In that case the energy meter did not respond at all.

If that s ok check the configured baudrate data bits stop bits parity etc. Please help me out in this regard. Check the modbus id of the meter.
