1:1 Links
Two PLCs can be connected through their RS-232C ports to create Link
Areas.
Applicable PLCs
A 1:1 Link can be create between any of the following SYSMAC PLCs:
CP1L-EL/EM, CQM1H, C200HX/HG/HE(-Z), CPM1A-V1, CPM2A, CPM2B,
CPM2C, and SRM1(-V2)
Connections
To create a 1:1 Link, connect the RS-232C ports on the two PLCs.
PLC Setup
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.
Link Area Size
The 1:1 Link Area in the CP1L-EL/EM 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
Operation
Here, operation is described assuming that the master is the CP1L-EL/EM
and the slave is the CPM2A.
