LO-HI The first register contains the low order word, the second
contains the high order word.

58.101 Data I/O 1 Defines the address in the drive which the Modbus master
accesses when it reads from or writes to the register
address corresponding to Modbus register 1 (400001).
The master defines the type of the data (input or output).
The value is transmitted in a Modbus frame consisting of
two 16-bit words. If the value is 16-bit, it is transmitted in
the LSW (least significant word). If the value is 32-bit, the
subsequent parameter is also reserved for it and must be
set to None.
