Selecting the replacement method
When C200H-series Basic I/O Units are replaced with CS1-series Basic I/O Units, rewiring is required. The C200H
I/O Terminal Block Conversion Adapter that allows the terminal block of the C200H-series Basic I/O Unit to be
reused for the CS1-series Basic I/O Unit is available. This enables efficient replacement by eliminating rewiring and
wiring check times.
Replacement method
Description
(1) Replacing all
C200H-series Units
with CS1-series Units
Replace all C200H-series Units with
CS1-series Units.
Cons: Rewiring of Basic I/O Units is required.
Reference
It takes about 1 hour to rewire all
Basic I/O Units (8 to 10 Units) mounted to a
Backplane.
(2) Using C200H I/O
Terminal Block
Conversion Adapters
Replace all C200H-series Units with
CS1-series Units, and mount the C200H I/O
Terminal Block Conversion Adapters to
CS1-series Units.
Pros: Rewiring of Basic I/O Units is not
required, which reduces replacement
time.
Cons: The installation depth is increased.
For details, refer to the
C200H I/O Terminal
Block Conversion Adapter Data Sheet
.
(3) Using Conversion
Cables for C200H
High-density I/O Units
Replace C200H-ID215 with CS1W-ID231, and
connect CS1W-ID231 using the same
connecting cables used for C200H-ID215.
In the same way, replace C200H-OD215 with
CS1W-OD231, and connect CS1W-OD231
using the same cable used for C200H-OD215.
Pros: Rewiring of I/O Units is not required,
which reduces replacement time.
Note 1. Depending on the type of Basic I/O Unit, there may be some restrictions (e.g. change in I/O
specifications or wiring) or some models cannot be used.
2. When you reuse a terminal block with wiring, confirm that there is no problem in the terminal block and
wiring conditions.
•
The screws are securely tightened.
•
The cables are not damaged.
•
There is no rust or corrosion.
•
The terminal block is not damaged. (The terminal block is securely inserted and fixed.)
