How to read RS 485 Data Using Arduino

Helllo,
This is Sadanand , I want to Read Rs485 data From KWH meter Using Arduino
Holding register ID is 1003 , & it is floting pt
Can somebody done simmiler project
Please guide me

Hello,

Have a read on that 2 articles it can give you some tips/advice:
https://circuitdigest.com/microcont...nication-between-arduino-uno-and-arduino-nano
https://circuitdigest.com/forums/ar...nergy-meter-data-through-modbus-using-arduino

Also what is OEM/model /type of the energy meter.

They are lots of threads on the web discussing on the subject that you posted.

Have a search on the web you surely to get the informations you need .

I hate to be harsh, but don't use Arduino for industrial projects. You are potentially taking a major (unnecessary) risk for your customer. What is the reward? The axiom here: Just because you can, doesn't mean you should.
 
Hello

Here is an interesting article with demonstration of how you can use a Raspberry PI + IPESOFT D2000 for data acquisition from electrometers. With energy meters you can use various protocols Modbus, DLMS/COSEM ...... supported at IPESOFT D2000.

It is up to you if you will use industrial version of Raspberry or standard Raspberry PI with an extension using HAT with implemented the RS-485 interface

What would you advise to use instead?
 
Take a look at a Moxa (brand) NPort 5130. This device will convert your RS-485 signal to Ethernet. Using a PC connected to that same Ethernet network, set up a virtual COM port. Next you'll use a driver (depending upon what the protocol is, e.g. Modbus, etc.) to read the data.
