Command 03, Read four Floating Point values starting at Address 1.
Result = 1234.56789, 0.0 -1234.568, 10000.
CODE 04
This function code is used to read from 1 to 125 contiguous input registers in a remote
device. The Request PDU specifies the starting register address and the number of registers. In
the PDU, registers are addressed starting at zero. Therefore input registers numbered 1-16 are
addressed as 0-15.
The register data in the response message are packed as two bytes per register, with the binary
contents right justified within each byte. For each register, the first byte contains the high-order
bits and the second byte contains the low-order bits.
