*1. During a broadcast, no response will be sent back.
*2. Note that the coil start address is 0006, which is 1 less than the coil number 0007: Coil start address = Coil
number - 1.
*3. Since written data occupies both MSB and LSB as a set, make the data to have an even number of bytes by
adding one byte of padding data, even if you actually need to change an odd number of bytes.
A multi-function input terminal is recognized as ON when either the terminal block input or the commu-
nications setting turns ON.
Also note that the Multi-function Input Monitor (d005) monitors the terminal block input only.
If the Write to Multiple Coils function is not executed normally, refer to 8-5-9 Exception Response on
page 8-20.
(Example) When the status of coils from coil number 0001 to 000D hex is written, the order of data is
as shown below. Data 1 is the initial byte data to send.
Data 1 0008 hex
