4-3 1:1 Link Area
The 1:1 Link Area contains 1,024 bits (64 words) with addresses ranging from
CIO 3000.00 to CIO 3063.15 (CIO 3000 to CIO 3063).
These bits are used to create 1:1 links (i.e., shared data link areas) by con-
necting the RS-232C ports of two PLCs, including the CP1L, CPM1A,
CPM2A, CPM2B, CPM2C, SRM1(-V2), CQM1H, and C200HX/HG/HE(-Z).
Refer to
6-3-6 1:1 Links
for information on using 1:1 links.
