Write multiple holding register data (H10 or 16)
You can write data to multiple holding registers.
Query message
Normal response (Response message)
The normal response data to (including CRC check) of the normal response are the same

Message Description
Slave Address
Set the address to which the message will be sent. Setting of address 0
enables broadcast communication.
Function Set H10.
Starting Address
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.
No. of Points
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.
Byte Count
The setting range is H02 to HFA (0 to 250).
Set twice greater than the value specified at
.
Data
Set the data specified by the number specified at . The written data are
set in order of Hi byte and Lo byte, and arranged in order of the starting
address data, starting a 1 data, starting a 2 data ...
