Operation
Two PLCs can be connected through their RS-232C ports to create Link
Areas.
A 1:1 Link can be create between any of the following SYSMAC PLCs:
CP1L, CQM1H, C200HX/HG/HE(-Z), CPM1A-V1, CPM2A, CPM2B, CPM2C,
and SRM1(-V2)
To create a 1:1 Link, connect the RS-232C ports on the two PLCs.
Master
RS-232C
1:1 Link
Set the PLC to a 1:1 Link Master or a 1:1 Link Slave in the PLC Setup. Set the
other PLC to the opposite setting.
The 1:1 Link Area in the CP1L is from CIO 3000 to CIO 3015 (16 words).
Even if a 1:1 Link is created with a CQM1H or C200HX/HG/HE(-Z) PLC, the
1:1 Link Area will be only 16 words on both sides of the link, and only LR 00 to
LR 15 will be used in the CQM1H or C200HX/HG/HE(-Z) PLC. LR 16 to LR 63
cannot be used for 1:1 Links
Here, operation is described assuming that the master is the CP1L and the
slave is the CPM2A.
