Write in Holding Registers [10h]:
This function writes data in consecutive holding registers. An example follows:
x
Write “3000 seconds” as the first acceleration time 1 (F002) in an inverter having a
slave address “8.”
x
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.

Note 2:
This is not the number of holding registers. Specify the number of bytes of
data to be changed.
Note 3:
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.
When writing in selected holding registers fails, see the exception response.
