Setting Data Links
Section 5-2
1:N Allocation, Common Type
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: (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.
