The value of this system register must be identical for all stations.
When link areas are allocated as shown above, the send area of station no. 1 can be
transmitted to the receive areas of stations no. 2, 3, and 4. Also, the receive area of station
no. 1 can receive data from the send areas of stations no. 2 and 3. Station no. 4 is allocated
as a receive area only and can receive data from stations no. 1, 2, and 3, but cannot send
data to other stations.

8.7.2.3 Partial Use of Link Areas

In the link areas available for PLC link, link relays with a total of 1024 points (64 words) and
link registers with a total of 128 words can be used. This does not mean, however, that it is
necessary to reserve the entire area. Parts of the area which have not been reserved can be
used as internal relays and internal registers.
