Write to Multiple Holding Registers [10 hex]
Writes data to consecutive multiple holding registers.
Example) Writing 10 Seconds to Inverter with Slave Address 1 as
1st Acceleration T
ime 1 (F07) V
alue
Because the holding registers 1103 to 1104 hex for the 1st Acceleration Time 1 (F07) has a data reso-
lution of 0.01 s, to set 10 seconds, set the written data to 1000 (0000 03E8 hex).

*1. During a broadcast, no response will be sent back.
*2. Note that the holding register start address is 1102 hex, which is 1 less than the register number 1103
hex: Register starting address = Register number - 1.
*3. This is not the number of holding registers, but the number of bytes to be changed actually.
