Appendix 9
The following table lists the backup/restoration functions. GOT also has the backup/restoration function.
Application of each function, executable operating status, and target data are described as follows.

Ways to Use Different Types of the
Backup/restoration Function
Application
This function is used when a CPU module is
replaced due to a failure or other reasons.
The function backs up the data in the CPU
module at a failure, and after another CPU
module is mounted on, restores the data to
the replaced CPU module.
The operation of this function is performed
while the CPU module is stopped.
For the device data, recovery target is only
file register files or devices that the latch
range is specified.
One backup data can be stored.
This function is used when the CPU module
is created without using a personal
computer.
The data in the CPU module is backed up
periodically, and the data can be restored
depending on the circumstance such as
recovering from an error state of programs
or device data.
Note that the data protected by the security
functions cannot be backed up or restored.
All the device data in the CPU module
including file register files that the latch
range is specified. Only the device data can
be restored.
Multiple backup data can be stored.
This function is used when the same device
supporting iQ Sensor Solution is created
without using a personal computer.
The function backs up the setting data such
as parameters of the device supporting iQ
Sensor Solution, and after a changeover,
restores the data to the device supporting iQ
Sensor Solution. Therefore, the process of
setting change can be simplified.
This function is used to when the same
system is created without using a personal
computer.
The function backs up setting data,
including programs, parameters, and setting
values, for a controller connected to the
GOT to a Compact Flash card or USB
memory in the GOT periodically. The data
backed up can be restored the controller.
The security function using passwords can
be added to the setting information of
controllers.
The target device data is only file register
files.
Multiple backup data can be stored.
