15 (0x0F) Write Multiple Coils
For slave coils, data for a specified number of coils starting from a specified address is changed.
When broadcast (0) is specified, coils of all slave devices with the same address will be rewritten.
The coil address, new number of bytes and output value are specified in the request.
* If rewriting a coil which turns the signal to ON level or OFF level, be sure
to set the priority of the
level input signal (setting mode 4-7) to "1: communication priority".
* N = Number of coils/8, N = N+1 in case the division is not possible.
Example) Turning ON/OFF accumulation clear (address 00009) starting
from digital zero (address 00005).
Note that the relative address is 0x04 when writing in digital zero.
The example shows how ON (1) and OFF (0) of the F701+ is rewritte
n.
Unused bits are filled in with 0.
* Consider execution confirmation of the coil to be something that is completed by a normal
response.
* Do not execute commands in the address combinations listed below.
When executed, commands will be carried out one by one, but may not operate properly.
- Addresses 00001 and 00002 - Addresses 00009 and 00010
- Addresses 00003 to 00006 - Addresses 00011 to 00013
- Address
