I am not able to communicate the 7M.24 energy meter through Modbus of the OPTA, I tested several programs that the platform makes available and also several programs that I found in the forum, but all were unsuccessful, in the serial monitor it says that it was not connected.
Does anyone have a solution to communicate between OPTA modbus rs485 and the 7M.24 power meter?
Hello!

Have a good day,
