3-1 Replacing an Existing PC Link System
Use CVM1-LK401 PC Link Units when replacing the CPU Rack of a C500/
C1000H/C2000H PC Link system with a CVM1-series Rack. Existing PC Link
cables can be used without changes, but there are limitations on communica-
tions between CVM1-LK401 PC Link Units and earlier models, as shown in
the following table.
Compatibility with
Other PC Link Units
CVM1-LK401 PC Link Units can communicate with other CVM1-LK401 Units,
C200H-LK401 Units, as well as C500-LK009-V1 Units in multi-level mode or
single-level LK009 mode. Depending on the existing models in the system
and their level settings, it may be necessary to replace Units or change oper-
ating level settings.
