Selecting the model
Reading PLC data
Description Reference page s
Select the corresponding CS-series Units, support software
and connecting cables to be used for replacing CV/CVM1
with CS. Some CV/CVM1 models can be used with CS, while
the others cannot. Read the reference pages to understand
recommended models and precautions and select a model.
Load the program, I/O Memory and other settings from the
CV/CVM1 using the programming software and connecting
cable.
Converting and
modifying data
Convert the data read from CV/CVM1 for CS.
Most of the data can be automatically converted while some
instructions are not. It depends on the used instructions or
the Unit model. Refer to the reference pages and modify the
data and program manually.

1. If production is conducted between the time from when the data was read and when it was
written, the present value in the program could be changed. Upload the data right before the
replacement work, modify it (if necessary), and download it to the new PLC.
2. The cycle times of CV/CVM1 and of CS are different, which may affect system operation.
Adjust the cycle time from the PLC settings. Some system configuration requires additional
program. Add the program, if necessary.
