No. Item Function
(1) Node Displays node address to set.
(2) PLC Sets the PLC type.
(3) Memory area Area 1 memory area
Area 2 memory area
(4) Start Address Area 1 start address
Area 2 start address
(5) Size Area 1 local node send size (in words)
Area 2 local node send size (in words)
(6) Status Data link status memory area (See note.)
(7) Ordered Destination
Nodes
Node Refresh Sequence
Beginning with the data link start address above, specify which nodes
are to have data refreshed at the local node address and the order in
which data is to be refreshed (i.e., the node refresh sequence). This
order will be the same for Area 1 and Area 2.
(For the local node address, data is sent from the local node area. For a
remote node address, data is received from the remote node address to
the local area.)
Note:
• The local node must be included in the refresh nodes.
• If the address of any node participating in the data links is not entered
here, data will not be received from that node.
Example: If 1, 2, 3 is input, node addresses 1, 2, and 3 will be allocated
in order, beginning with the start address.
(8) Make Default Click this button to make the values set for the above items the default
values for new data link settings.
(9) Next >> Click to proceed to the next dialog box.
Note: The default setting for data link status depends on the PLC being used. For details, refer
to the Controller Link Units Operation Manual (W309).

Item Data set Description
Node address 1 −
PLC type CS1G-CPU45 −
Memory area CIO
Start address 1000
Sets CIO 1000 as the data link start
address for the Area 1 local node.
Area 1
Send size 30 Sets 30 words as the send size (unit:
words) for the Area 1 local node.
Memory area D
Start address 500
Sets D00500 as the data link start
address for the Area 2 local node.
Area 2
Send size 30 Sets 30 words as the send size (unit:
words) for the Area 2 local node.
Ordered destination nodes 1, 2, 3 Specifies the node refresh sequence.
Beginning with the start addresses,
nodes 01, 02, and 03 are set in order.
(The local node address is 1, so
transmission is first, followed by
reception from node 02, and finally
reception from node 03.)
Memory area CIO Status
Start address 1100
Sets CIO 1100 as the data link status
start address.
