2-5 Data Areas for PC Link Systems
LR Area Allocation
In CVM1/CV Series PLCs, the Data Link Area (CIO 1000 to CIO 1063) is allo-
cated as the PC Link’s LR Area. Words CIO 1000 to CIO 1199 are also used
by SYSMAC LINK Units and Controller Link Units, so be sure that the words
used by those networks do not overlap the PC Link’s LR Area.
