Features of 1 to 1 Type 1:N Allocation

each slave node receives unique data from the master node (see a to d in
figure).
•
The master node receives all data sent by the slaves. The data sizes are
fixed for all nodes.
•
Slaves do not send or receive data with other slaves.
•
One area is selected from the bit-access areas (e.g., CIO Area) or
word-access areas (e.g., DM Area).
•
Data link areas are allocated in ascending order of node addresses.
•
Data link participation can be specified for each node.
