No. Item Function
(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).
