Write in Coil [05h]:
This function writes data in a single coil. Coil status changes are as follows:
Change data (high order)
Change data (low order)
An example follows (note that to command the inverter, set A002=03):
 Sending a RUN command to an inverter having slave address "8"
 This example writes in coil number "1."

No response is made for a broadcasting query.
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.
