Data communications are 1:1 between the master node and slave nodes.
Slaves do not send or receive data with other slaves.
Data link areas are allocated in ascending order of node addresses.
Data link participation can be specified for each node.
All slave nodes receive part of the data sent by the master node. In addition,
The master node receives all data sent by the slaves. The data sizes are
