This replacement guide describes the procedure to rebuild the system which uses the C200HS-series PLC by
introducing the CS1-series PLC instead. The CS1-series PLC has functions which can replace the functions and
operation of the C200HS-series PLC. Follow the below work flow to replace your system. Refer to the reference
pages for details.
1.
Work flow
1) Preliminary Steps: Take the following steps before starting the replacement work.
Selecting the model
Reading PLC data
Description
Reference pages
Select the units, programming software, and connecting
cables to replace C200HS with CS1.
Some C200HS-seires Units can be used with CS1. However,
some Units cannot be used with CS1. Read the reference
pages (recommended models and remarks) and select the
models.
Load the program, I/O Memory and other settings from the
C200HS using the programming software and connecting
cable.
Converting and modifying data
Convert the data read from C200HS for CS1.
Most of the data can be automatically converted; however, some
instructions and some Unit data cannot be converted.
Refer to the reference pages and modify the data and program
separately.

4. Reading data from C200HS
Preparing Units
Prepare the units, programming software, and connecting
cables.

user's manuals for Special I/O Units and CPU Bus Units for
details of installation.
Transfer the converted data to CS1.
To check the wiring, operate input and output bits to see if
they operate correctly.
Checking operation
Turn ON the power and check the operation.

Replacement completion
1. If production is conducted between uploading the program and executing replacement
work, data handled by the program may change. If so, upload the data right before the
replacement work, modify data (if necessary), and download it to the new PLC.
2. The cycle time of C200HS and CS1 are different, which may affect system operation. If
so, it is necessary to adjust cycle time in the PLC Setup.
