Modbus Energy Meter 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. Read voltage from eastron sdm230 modbus smart energy meter with modbus protocol. 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.
