See Example - Use Type Cast and array subset. NOTE-Some modbus documentaion use 1 as the first register. Labview uses 0 as the first register. So you may have to shift your index by -1 to get the correct starting register.

Unless the 32 bit number they are looking for is an integer rather than a single precision floating point.  Then they may need to use a U32 or I32 as the dataype for the type cast.
