“Quantity of registers” indicates how many words will be written.
“Byte count” indicates how many bytes will be written. If “quantity of register” is N,
then “byte count” is (N×2).
It is important to note: the response has a 16-word frame, so the maximum
"quantiy of registers" should be less than 13. Otherwise it will return an error
result.
Response
The normal response returns the function code, starting address, and quantity
of registers written.
