Modbus 32-bit registers

[MarcusH]

Hi

I got an Eaton nzm-xmc-tc-mb, this unit got a 32-bit register with High byte and low byte. I've never worked with this before so im having probles understanding how it works.

I think I understand the logic, but I got no idea how I should pull the data and write it.

Register manual (PDF document):

Can someone explain how this works and maybe give me a starter script to get me going?

Best regards
