Mapped is used to map one command to another. When the COMMAND is received it is mapped to the new MAPPED command and then issued to the device.
We have an X10 remote control pad with ON/OFF buttons. When one of the ON buttons is pressed, “pp_sofa60” in this case, map the ON command to a LEVEL command and send that instead. In this case when we press the button the light will come on to a level of 60% instead of full brightness.
