Write in Coils [0Fh]:
This function writes data in consecutive coils. An example follows:
• Change the state of intelligent input terminal [1] to [6] of an inverter having a slave address
“5.”
• This example assumes the intelligent input terminals have terminal states listed below.
When the Write in Coils command cannot be executed normally, see the exception response.

Query:
Note 1:
Broadcasting is disabled.
Note 2:
The starting coil number is one
less than the number of the coil to
be read first.
Note 3:
The change data is a set of high-
order data and low-order data. So
when the size (in bytes) of data to
be changed is an odd number, add
“1” to the data size (in bytes) to
make it an even number
Response:
Note 4:
Data is transferred by the specified
number of data bytes (data size).
No.
