Reading data from energy meter through Arduino

Reading data from energy meter through Arduino

Dear All,

We purchased Elmeasure LG1129, BM5140 and LG5310 series of meter and trying to read its holding register data values using Arduino Mega and RS485 to TTL converter in Arduino IDE but we haven't suceeded.

I tested the meter with USB to RS485 using modscan32 software, the software reads holding register data values, but with Arduino IDE it is not happening.

Trying from past 2 months pls help me out to resolve this problem
