Reading Battery Parameters through Modbus Protocol

Hello Everyone,

I have a battery with Modbus Communication. I am extracting data in labview through MODBUS Library. I have attached all VI and Screenshot. I am sending correct Host Data but I am not getting exact Response from BMS. I have also attached pictures of Battery Data which I got from its Application.

Thank you in advance.

Grated it's been a while since I did any Modbus programming but... I don't understand what you are doing with the Modbus data conversion:

When I was working with Modbus the first thing I did was make a VI to get all the parameters I needed then I could just call it.

 

My device used two registers for most measurements so this is what my "get measurement" vi looked like.

This does not scale the data, so you will need to apply any scaling factor to the resulting double output
