(2) Master and local stations

Data can be written into the send range of each station's link device (RY, RWw) and can be sent to any station on
the same network.
The status data of the link devices (RY, RWw) of the master station are stored in the link devices (RX, RWr) of
each local station.
The status data of the link devices (RY, RWw) of local stations are stored in the link devices (RX, RWr) of the
master station and the link devices (RY, RWw) of other local stations.
