A PC Link System is a communications system that exchanges I/O data
between PLCs independent of programming in the ladder program. The
CVM1-LK401 is the PC Link Unit for SYSMAC CVM1/CV-series PLCs.
Extra programming is not required to communicate through the PC Link Sys-
tem. PLCs with PC Link Units mounted can exchange data through their
shared LR Areas.

Content of LR 50 in C1000H
is reflected in CIO 1050 in
CVM1, where it becomes
SV for TIM 0100.
The PC Link System shares LR Areas to exchange up to 1,024 bits of data
(64 words).
In the CVM1/CV-series and CS-series PLCs, words CIO 1000 to CIO 1063
are allocated as the LR Area.
In the C-series PLCs, words LR 00 to LR 63 are used as the LR Area. (In the
C500, the area is LR 00 to LR 31.)
