Features of 1 to 1 Type 1:N Allocation

•Data communications are 1:1 between the master node and slave nodes.

•All slave nodes receive part of the data sent by the master node. In addi- tion, 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.
