(e) The startup node must be set as a participating node of the data
links. If not, the data links will not start.
Area 1
(1) Area and start word
(2) Number of send words for master node
(3) Number of send words per slave node
Area 2
(4) Area and start word
(5) Number of send words for master node
(6) Number of send words per slave node
Features of Common Type 1:N Allocation
• Data communications are 1:1 between the master node and each of the
slave nodes.
• All slave nodes receive the data sent by the master node.
• The master node receives all data sent by the slaves. Therefore, the
reception size for the master node is the node send data size multiplied by
the number of slave nodes.
• Slaves do not exchange data with other slaves.
• Area 1 is set in the bit-access areas and Area 2 is set in the DM Area.
• Data link areas are allocated in ascending order of node addresses.
• Each node can be specified to either participate or not participate in the
data links.
