Write in Coils [0Fh]:
This function writes data in consecutive coils. An example follows:
• Change the state of intelligent input terminal [1] to [5] of an inverter having a slave
address “5.”
• This example assumes the intelligent input terminals have terminal states listed below.

Query:
Note 1:
Broadcasting is disabled.
Note 2:
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.
