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 "8."
This example assumes the intelligent input terminals have terminal states listed
below.

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 start coil number ("7"), add "1"
to the data size (in bytes) to make it an even number.
Note 3:
The PDU Coils are addressed starting at zero. Therefore coils numbered 1-31
are addressed as 0-30. Coil address value (transmitted on Modbus line) is 1
less than the Coil Number.
