• Description of normal response
1) to 4) (including CRC check) of the normal
response are the same as those of the query
message.
Example: To write 0.5s (H05) to 41007 ([Pr. 7]) at the slave address 25 (H19) and 1s (H0A) to 41008 ([Pr. 8]).

Set the address to which a message will be sent. Setting of address 0 enables
broadcast communication.
Set H10.
Set the address where holding register data write will be started.
Starting address = Starting register address (decimal) - 40001
For example, setting of the starting address 0001 reads the data of the holding
register 40002.
Set the number of holding registers where data will be written. The number of
registers where data can be written is a maximum of 125.
The setting range is H02 to HFA (0 to 250).
Set twice greater than the value specified at 4).
Set the data specified by the number specified at 4). The written data are set in
order of Hi byte and Lo byte, and arranged in order of the starting address data,
starting address + 1 data, starting address + 2 data ...
