The “Length” indicates that there will follow 2 byte. The 16-bit figures will arrive in
High-Low order.
Byte order of the 32-bit figures: (sample: 4byte work-hour counter)
Hi Lo Hi Lo 2x16bit
Hi Lo 32bit

: Dev addr fcode Reg. address Data LRC CR LF
Hi Lo Hi Lo
In the example the "Dev addr" is the unique number of the device.
The fcode=06 indicates the writing request.
The Reg.address gives the 16-bit address.
Data: contains the 16-bit data.
LRC, CR, LF: same as in case of reading.
Only one 16-bit register can be written at a time.
If there was no error, the answer will be the same as the order:
