Description of Operation
Restoring function block
data files from a Memory
Card to the Unit
112
Set the DIP switch on the front of the CPU as shown in the following table,
then press and hold the Memory Card power supply switch for 3 s.

This creates a function block data file and writes that file along with other
backup files to the Memory Card. When the Memory Card power supply
switch is pressed, the MCPWR indicator on the front of the CPU Unit flashes
once and remains lit while data is being written. The indicator goes out after
data has been written normally to the Memory Card.
Note (1) When password protection is set for the Loop Controller using the CX-
Process Tool, the RDY indicator on the front of the Loop Controller will
flash if the Memory Card power supply switch is pressed to perform sim-
ple backup. Perform simple backup after clearing the password set for the
Loop Controller using the CX-Process Tool. If the easy backup operation
is performed to backup data in a Memory Card for function block data in
a Loop Controller for which a password is set, an empty backup file will
be created on the Memory Card.
(2) Online operations may not be possible from the CX-Process Tool during
simple backup. If they are attempted, a communications timeout error or
an error response code of 3001 may occur.
(3) Recovery will start if a Memory Card is inserted and the power supply is
turned ON with pin 7 on the DIP switch turned ON. Be sure to turn OFF
pin 7 after the operation has been completed.
(4) Do not perform a save operation to flash memory during execution of an
easy backup operation on a Loop Control Board of Version 3.0 or later.
Doing so will prevent the data from being backed up correctly. If this data
is later restored from the Memory Card, a database error will occur and
bit 10 in A424 will turn ON.
Set the DIP switch on the front of the CPU as shown in the following table,
then turn ON the PLC.
