1. Turn power OFF to the PLC.
2. Connect the cable to the CPU Unit.
3. Turn power ON to the PLC.
4. Read the same function block file (that was set aside and appended with
the .ist extension) as the data on the Loop Control Board to be replaced
from hard disk or other storage medium using CX-Process Tool.
5. To check whether or not the file is the same as that on the Loop Control
Board, use CX-Process Tool to verify only CX-Process Tool default data
between the Loop Control Board and the function block file that has been
read.
6. Upload the function block data from the Loop Control Board. Read the pa-
rameters from SCADA software, a PT, etc.
7. Turn power OFF to the PLC.

1. Turn power OFF to the PLC.
2. Replace the Loop Control Board.
3. Connect the cable to the CPU Unit.
4. Turn power ON to the PLC.
5. Use CX-Process Tool to download the function block file (appended with
the .ist extension) that was set aside in the hard disk or other storage me-
dium to the Loop Control Board.
