Units per PLC
In a single-level system, one PC Link Unit can be mounted in a CVM1/CV
Series PLC. In a multi-level system, two PC Link Units can be mounted.
Note
The PC Link Units will not detect an error even if two PC Link Units with con-
flicting operating level settings (one or both single-level, both multi-level link
#0, or both multi-level link #0) are mounted in the same PLC. To be sure that
the PC Link operates properly, verify that the level settings are correct.
One PC Link Unit set for single-level operation can be mounted in a single
PLC, or two Units set for multi-level operation (one set to Link #0 and the other
set to Link #1).
