Modbus RS485 - Floating 32 point - IEEE 32

[Edilson Adriano Lucas]

Hello my friends, I have some difficulties communicating with a power meter, it has a Floating Point 32 address, and I can't communicate.
I performed tests on KepServer and got success and also with ModbusScan.

You could be helping me set up the program or teach me some procedure you might be doing to establish communication.

Attached is the list of registers.

For Modbus addresses that start with 3xxxx you need to be reading input registers.  Then you'll have to deal with the floating point nature of it.

Post whatever code you've started so we can have a look.
