3 Coil start number (MSB)
4 Coil start number (LSB)
5 Number of coils (MSB)
6 Number of coils (LSB)
*3
7 Number of bytes
8 Change data (MSB)
*3
9 Change data (LSB)
10 CRC-16 (MSB)
11 CRC-16 (LSB)
*1. There is no response for broadcasting.
*2. Note that the start number is reduced by 1.
*3. Since the change data comprises of both MSB and LSB as a set, make the byte to be an even
number by adding 1, even if the byte that actually needs to be changed is an odd number.
If writing into multiple coils cannot be performed normally, refer to the "Exception Response" section.
