Write in Holding Registers [10h]:
This function writes data in consecutive holding registers. An example follows:
Write "3000 seconds" as the first acceleration time 1 (F002) in an inverter having a
slave address "8."
This example uses change data "300000(493E0h)" to set "3000 seconds" as the data
resolution of the registers "1014h" and "1015h" holding the first acceleration time 1
(F002) is 0.01 second.

This is not the number of holding registers. Specify the number of bytes of
data to be changed.
The PDU Register Number are addressed starting at zero. Therefore register
numbered "1014h" are addressed as "1013h". Register address value
(transmitted on Modbus line) is 1 less than the Register Number.
