Data Link Table Example Section 4-7
4-7 Data Link Table Example
In this example, the refresh parameters differ from node to node, so the data
link tables will also differ from node to node. There are four nodes in the net-
work (2, 5, 6, and 8), but some nodes will not receive data from all other
nodes. The settings for the common link and refresh parameters are shown
after the data flow.
In this example, node 5 does not receive data from node 8, and node 6 does
not receive data from node 2. Also, node 8 only receives CIO Area data from
the other nodes
Create the data link tables for each participating node using CX-Net in CX-
Programmer. The following settings are required.
• Local node send size
• PLC type
• Local node data link start address
• Refresh node order
Node 5 Node 2 Node 6 Node 8
