2.  Selecting the replacement method 
When  C200H-series  Basic I/O Units are replaced with CJ-series  Basic I/O Units, rewiring is required. When 
C200H-ID215 and C200H-OD215 C200H High-density I/O Units are replaced with CJ-series I/O Units, the same 
connecting cables that were connected to C200H High-density I/O Units can be used. 
 
Using Conversion Cables 
for C200H High-density 
I/O Units 
Replace C200H-ID215 with CJ1W-ID231, and 
connect CJ1W-ID231 using the same 
connecting cables used for C200H-ID215. In 
the same way, replace C200H-OD215 with 
CJ1W-OD231, and connect CJ1W-OD231 
using the same cable used for C200H-OD215. 
 
Pros: Rewiring of I/O Units is not required, 
which reduces replacement time.
