I am doing similar project. My meter is sycon 9900-P. Sir I request you to tell which software you have used to communicate meter and arduino . Will you please provide me the connection details of your project. I am doing this project in final year. I am using arduino first time. I saw your project details but I didn't get connections. Please reply as early possible.
Hello I hope you read this, I'm not sure about the "software" because you only have to put the codes in the package of the modbus message. In the arduino code. You have to read the details of your meter. Maybe you need to read first more information about libraries.
THe connection is simple you only need one RS485 module, and plug in directly to your meter, as I showed in the post.
