Hitachi X200 Series instruction manual 16, Write in Holding Registers 10h

B−16

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.

Note 1: Broadcasting is disabled.

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.
