Data Link Area

Data Link Area addresses range from CIO 1000 to CIO 1199 for words and CIO 1000.00 to
CIO 1199.15 for bits. Words in the Data Link Area are used for data links when LR is set as the data
link area for Controller Link Networks.
A data link automatically (independently of the program) shares data with Data Link Areas in other CPU
Units in the network through Controller Link Units mounted to the PLCs.
Data links can be generated automatically (using the same number of words for each node) or manu-
ally. When a user defines the data links manually, any number of words can be assigned to each node
and nodes can be made receive-only or send-only. Refer to the Controller Link Units Operation Manual
(Cat. No. W309) for details.
Words in the Data Link Area can be used in the program when LR is not set as the data link area for
Controller Link Networks are not used.

Bits in the Data Link Area can be force-set and force-reset.
