The following table outlines the procedures and precautions for replacement
of PC Link Units.
Replace with CVM1/CV-series compo-
nents.
Some can be used in the CVM1/CV
Series.
Replace with CVM1/CV-series compo-
nents.
Replace with CVM1-LK401.
The unit number must be set since the
CVM1-LK401 is a CPU Bus Unit.
Match the CVM1-LK401's settings to
the settings of the C500-LK009-V1
Units in the PC Link.
(One exception is the LK003 mode,
which cannot be used. In this case,
change the C500-LK009-V1 Units'
settings.)
These settings are not set in the
CVM1-LK401.
Replace LR 00 to LR 63 addresses
with CIO 1000 to CIO 1063.
Replace SR 247 to SR 250 bit
addresses with CIO 1500 + 25 × N to
CIO 1500 + 25 × N +3 (N = unit num-
ber).
Replace AR 2411 and AR 2412 bit
addresses with bits 11 and 12 of CIO
1500 + 25 × N +4 (N = unit number).
In the CVM1/CV Series, the status of
the CVM1-LK401 can be monitored
from the ladder program.
We recommend using synchronous
operation.
