Fixed to 0. (When the slave receives data other than 0, it does not send the response
message.)
0 is returned in the response from the slave.
쐋
Length field The data length from the unit identifier to the data is stored in byte.
쐏
Unit identifier Fixed to 255
쐄
Function Set H06.
쐂
Register address
Set the holding register address to write data to.
Register address = holding register address (decimal) - 40001
For example, when register address 0001 is set, data is written to holding register address
40002.
쐆
Preset data Set the data to write to the holding register. Write data is fixed at 2 bytes.
