Functions
<Writing Into Multiple Coils [0Fh]>
Rewrites consecutive multiple coils.
(Example)
Change the status of multi-function input terminals [1] to [5] of the Inverter with the slave address
"8".
Refer to the following table for the status of multi-function input terminals [1] to [5].
*1.There is no response for broadcasting.
*2.Since the change data comprises both MSB and LSB as a set, make the byte to be an even num-
ber by adding 1, even if the byte which actually needs to be changed is an odd number.
*3.Note that the coil start address is "6", which is smaller by 1 than the coil number "7". The coil
addresses for coil numbers from "1 to 31" are "0 to 30".
Refer to "<Exception Response>" (4-75) if writing into multiple coils cannot be performed normally.
<Writing into multiple holding registers [10h]>
Writes into consecutive multiple holding registers.
(Example)
Set "3000 seconds" to acceleration time 1 (F002) for the Inverter with the slave address "8".
The data resolution of the holding register "1024h, 1015h" of acceleration time 1 (F002) is 0.01
seconds. To set 3000 seconds, set change data to "300000 (000493E0h)".
