D-3 Restoring Unit Setup Files
In order to restore the Unit’s parameter sets from the Memory Card mounted
to the CPU Unit, perform the following procedure.
1 Power down the PLC and insert a Memory Card into the Card slot.
2 Turn ON pin 7 of the DIP switch on the front of the CPU Unit (behind the
cover above the Memory Card slot).
3 Turn ON the PLC’s power supply.
4 When the PLC’s power is turned ON, the MCPWR Indicator on the front of
the CPU Unit will light and flash once. The MCPWR Indicator will remain lit
while the data is being read. The Indicator will go OFF after the data has
been read properly. During the Data Transfer the Parameter Transfer in
Progress bit in Unit Status Word (CIO Word n+4) will turn ON.
5 Restart the PLC.
Note 1 Data will not be read from the Memory Card to the CPU Unit if pin 1
of the DIP switch is ON (write-protecting program memory).
2 A CJ1 CPU Unit will remain in PROGRAM mode after the simple
backup operation has been performed and cannot be changed to
MONITOR or RUN mode until the power supply has been cycled.
After completing the backup operation, turn OFF the power supply to
the CPU Unit, change the settings of pin 7, and then turn the power
supply back ON.
3 File backups may take from several seconds to several minutes.
Refer to CS/CJ-series Programming Manual (W394) for information
on execution times.
4 If an error occurred in the transfer from the Memory Card to the Unit,
the File Read Error bit in Unit Status Word (CIO Word n + 4, bit 09)
will turn ON. To correct this, re-perform the Restore action. If the
problem persist, use CX-ConfiguratorFDT to download the original
settings from the PC.
