(4) Configuration of the controller at the restoration
The configuration of the controller must be the same as the one at the backup.
When the configuration of the controller at the restoration differs from the one at the backup, the restoration cannot
When the configuration of the controller at the restoration is the same as the one at the backup, the restoration can
be executed even though the connection type or CH No. does not match.
When the FXCPU is connected, the model, memory cassette (whether it is installed or not), and memory capacity of
the memory cassette must be the same as the ones at the backup.
(5) Operation of the controller
The controller may operate unexpectedly by changing a set value or device value at the restoration.
To execute the restoration, sufficiently check the data to be restored and the operation of the controller.
■3. Precautions for backing up and restoring data
(1) Password for the backup/restoration
When the password on the controller side is changed after the password for the backup/restoration has been set, the
password for the backup/restoration needs to be changed.
For how to set a password for the backup/restoration, refer to the following.
15.8.5 Security and password
(2) Precautions for using GT Designer3 (GOT2000)
Do not perform the following operations in GT Designer3 (GOT2000) while the backup or restoration is executed.
• Installing the BootOS
• Writing the package data and installing a communication driver, basic system application, and advanced system application
When the operations above are performed, the backup or restoration processing is canceled.
(3) Precautions for using GX Developer
Do not access the target controller of the backup or restoration using GX Developer while the
backup or restoration is executed.
Accessing the target controller cancels the backup or restoration processing.
Do not execute the backup or restoration while the target controller is accessed using GX
If doing so, a communication error occurs in GX Developer.
(The backup or restoration processing is executed.)
(4) CPU to which a security key is set
The data in the CPU to which a security key is set cannot be backed up or restored.
To back up or restore the data, review the CPU setting.
When both the CPU with a security key and the one without a security key exist in the target controller of the backup
or restoration, only the data in the CPU without a security key can be backed up or restored.
■4. Precautions for using the QCPU
Restoring data to the QCPU in the factory shipment status or whose memory is formatted can be performed only in the
• When the single CPU system is used: The connection type is the direct CPU connection.
• When the multiple CPU system is used: The connection type is the direct CPU connection.
However, the restoration cannot be executed at once to multiple CPUs in the multiple CPU system including the QCPU
that is in the factory shipment status or whose memory is formatted.
Execute the restoration for each CPU.
Restore the data to CPU No.1.
Reset CPU No.1.
Operation in GT Designer3 (GOT2000)
Restore the data to CPU No.2.
Reset CPU No.2.
