Orno we 516, node red and usb serial rs485 adapter

ok, thats what i needed.

Firstly - in ModBus, a register is 16 bits (AKA 2 bytes)

As you can see from that document, the values labeled as being float and that the (byte) length of them are 4 each

So firstly, change your read to request 6 registers (6 registers == 12 bytes)

Then pass that through a buffer parser node like this...
