RegisterBitPoint (RJ12)

The ModbusRJ12Network uses the same data points as the ModbusAsyncNetwork.

The ModbusAsyncRegisterBitPoint component is responsible for reading Boolean values from a bit in a specified register in the device. The component has to be placed under the ModbusAsyncDevice component.
