1.
Make a note of the unit number of the PCU to be replaced.
2.
Save the parameters and operating data for the PCU to be replaced to a
floppy disk or a hard disk using CX-Position.
When not using CX-Position, first read the parameters and operating data
to the PLC’s DM Area using a data transfer bit or the IORD instruction, and
then transfer the contents of the DM Area to a floppy disk or hard disk using
CX-Programmer.
3.
Turn OFF the power supply.
4.
Make a note of the way in which the PCU is wired. (It is recommended that
the cables are labelled.)
5.
Replace the PCU, and reconnect the wiring as before.
6.
Set the unit number for the PCU.
7.
Turn ON the power supply to the PLC.
8.
Transfer the saved parameters and operating data to the PCU using CX-
Position. If the parameters and operating data have been saved in the
PLC’s DM Area, first transfer them to the PLC using CX-Programmer, and
then transfer them to the PCU using a data transfer bit or the IOWR in-
struction. After transfer, write the parameters and data to PCU’s flash
memory.
9.
Turn the PLC power OFF and back ON.
