9 Backup Functions
9-20
NJ-series CPU Unit Software User’s Manual (W501)
You can compare the Controller data and the data in a backup file on the SD Memory Card in the CPU
Unit.
• The Controller data and the data in a backup file that is saved in the specified directory of the SD
Memory Card are compared.
• The data groups that are processed by the verification operation are specified in the RestoreCom-
mand.ini file (restore command file).
• The present values of variables, the present values in memory used for the CJ-series Units, and the
absolute encoder home offsets are not compared because these values may change while the verifi-
cation is in process.
• When you verify the data, the verification results file (VerifyResult.log) is created in the specified
directory. The verification results are stored in this file. If a verification results file already exists in the
specified directory, it will be overwritten. However, if the SD Memory Card is write-protected, the veri-
fication results files will not be created.
• If there is not a restore command file in the specified directory of the SD Memory Card, all of the data
from the backup files in the specified directory that can be compared will be compared.
• If the Unit and slave configuration in the backup file is not the same as the actual configuration of the
Controller, a Verification Error will occur.
• The SD Memory Card will remain mounted after completion of the verification operation.
