Correction
Replace the CPU Unit with a CPU
Unit that has the same model as the
CPU Unit that was used to create the
backup files.
Or, place the backup files with the
correct model for the used CPU Unit,
in the folder specified by the
_Card1PrgTransferCmd.DirName
system-defined variable.
If you transfer SD Memory Card pro-
grams, select the Do not use Option
for the Write protection at startup set-
ting of the CPU Unit.
Make sure that TRUE is set in the
_Card1PrgTransferCmd system-
defined variable to transfer required
files.
Perform the same corrective mea-
sures as for when the format of the
SD Memory Card is not correct or the
SD Memory Card is damaged.
If none of the above causes applies,
replace the SD Memory Card.
Replace the CPU Unit with a CPU
Unit that has the same or a newer
database connection service version
than the database connection service
version of the CPU Unit that was used
to create the backup files. Or, place
the backup files with the correct data-
base connection service version for
the CPU Unit, in the folder specified
by the _Card1PrgTransferCmd.Dir-
Name system-defined variable.
Replace the CPU Unit with a CPU
Unit that has the same or a newer
robot version than the robot version of
the CPU Unit that was used to create
the backup files. Or, place the backup
files with the correct robot version for
the CPU Unit, in the folder specified
by the _Card1PrgTransferCmd.Dir-
Name system-defined variable.
5 Troubleshooting
Prevention
Make sure that the model of the CPU
Unit is the same as the model of the
CPU Unit that was used to create the
backup files.
If you transfer SD Memory Card pro-
grams, select the Do not use Option
for the Write protection at startup set-
ting of the CPU Unit.
Make sure that TRUE is set in the
_Card1PrgTransferCmd system-
defined variable to transfer required
files.
Perform the same preventive mea-
sures as for the following events: SD
Memory Card Invalid Format or Faulty
SD Memory Card.
Do not remove the SD Memory Card
or turn OFF the power supply while
the SD BUSY indicator is lit. Or,
replace the SD Memory Card periodi-
cally according to the write life of the
SD Memory Card.
Make sure that the database connec-
tion service version of the CPU Unit
and the database connection service
version of the backup files are com-
patible.
Make sure that the robot version of
the CPU Unit and the robot version of
the backup files are compatible.
