Inputs (RX and RWr) of the master station are stored in the outputs (RY and RWw) of the standby master station. By
transferring the outputs (RY and RWw) of the standby master station to the inputs (RX and RWr), inputs from the slave
stations are continued. (Shaded areas in the figure above) ( Page 86 Communication Example Using the Standby Master
