ModBus RS485 not reading from profile but reading from "read test" - robikozo - 22.09.2022
Hello, I am currently working with a smart modbus energy meter, and I am trying to connect it to log data, if I try to read data with "Read Test" button it shows exactly as its supposed to, (I took an example of grid frequency, and it shows the right amount) but when i apply the same settings to a modbus profile and upload it i get a return of an enormous number and I can't figure what is going on, any ideas?
I included the profile I am using right now.
Sincerely,
Robert

Hi,
Try to add "datatype" : "float32" in every item.
Best regards Cristian

What were the settings you used via read test? I'm more than sure that different registers will have different settings.

This is the setup I was using.
I also included the reading that the profile is giving out.

Do as Cristian suggested. Your profile is missing correct "datatype" field for each mapping entry.
