The 1:1 Link Area contains 256 bits (16 words) with addresses ranging from
CIO 3000.00 to CIO 3015.15 (CIO 3000 to CIO 3015).
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-EL/EM, CPM1A,
CPM2A, CPM2B, CPM2C, SRM1(-V2), CQM1H, and C200HX/HG/HE(-Z).
