Table 4-2.Register Definitions
Function codes 03 (read holding registers) and 04 (read input registers) are the
only codes supported for reading these registers, and function codes for writing
holding registers are not implemented. We recommend that the floating point and
long integer registers be read in a single operation with the number of registers
being a multiple of two. If these data are read in two separate operations, each
reading a single 16-bit register, then the value will likely be invalid.
