Conversion of register in float32 to real

[Smartwatt12]

I need help with reading PMxxxx registers in float32.

Hello @Smartwatt12 ,

A little context here will go a long way. Are you talking about modbus registers? Often with 32 bit registers in modbus, the word order is important. Some devices, the high word is first and other devices the low word is first, once you determine that the float usually follows IEEE 754 float format.
