Note 1:
No response is made for a broadcasting query.
Note 2:
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.
When writing in a selected coil fails, see the exception response.
