Setting Data Links
Section 5-2
1:N Allocations, 1 to 1 Type
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.
Address N: (100

Controller Link Unit number)
When bits 6, 5 and 4 are set to 1, 0 and 1 respectively, automatic setting with
1:N allocations is specified.
