8-5-7 Write to Multiple Holding Registers [10 hex]
Writes data to consecutive multiple holding registers.
Because the holding registers 1103 to 1104 hex for the 1st Acceleration Time 1 (F002) has a data reso-
lution of 0.01 s, to set 10 seconds, set the written data to 1000 (0000 03E8 hex).
⚫ Query
(Register address) = (Register number) − 1
0000 03E8 hex → 1000 dec → 10.00 s
⚫ Response
No.

*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.
If the Write to Multiple Registers function is not executed normally, refer to 8-5-9 Exception Response
