Features of Common Type 1:N Allocation

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

•All slave nodes receive the data sent by the master node.

•The master node receives all data sent by the slaves. The reception size for the master node is thus the node send data size times the number of slave nodes.

•Slaves do not send or receive data with other slaves.

•Area 1 is selected from the bit-access areas (e.g., CIO Area) and area 2 is selected from 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: D30000 + (100 ⋅ Controller Link Unit number)

15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0

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