5.14.2.3 Backup Data Restoration

To restore backup data, perform the reversed backup operation (Enter the setting for the personal computer in [A:Dev], and
the setting for CNC controller in [B:Dev]).
The PLC must be STOP before restoration is started.

5.14.2.4 Precautions

Considerations for input/output with the conditions in the CNC
The backup data for each project (PROJECTxx.LAD) may not be input depending on the status in the CNC such as stored
sequence programs, and data size.
This section describes the causes and remedies for the issues where backup for each project data (PROJECTxx.LAD) cannot
be input.
Causes and remedies for when backup data for each project cannot be input
Causes
Exceeds the device size that can be used
in all projects
An attempt to input the data to unavailable
project.
Size of data to input is greater than the
storage area.
Precautions for inputting or outputting to or from CNC of different version
Do not store data written to the CNC on GX Works2 in a system of D1 or an earlier version.
Error details
The data size has exceeded the available
device size.
Input has been attempted for an unavailable
project.
Data to input is too large.
241
Remedy
The size of empty/vacant/reserved device is
not sufficient.
Correct the multi-project parameter (device
points) to increase empty/vacant/reserved
size.
Input the data to an available project.
Correct the multi-project parameter (project
percentage) to increase the storage area
size to be greater than the PLC data (se-
quence program and comment) of the proj-
ect-based backup data.
