In order for data in a Unit to be backed up, that Unit must support the simple backup function. Refer to
the operation manual for the specific Unit to check whether this function is supported.

Precautions for Correct Use Precautions for Correct Use
When using a simple backup file to restore data, use a CPU Unit of the same model as the
backup source. If a CPU Unit of a different model is used, the following operations will result.
• If the number of EM banks for the simple backup file is greater than that of the CPU Unit where
the data is to be restored, the data will not be restored.
• If the number of EM banks for the simple backup file is less than that of the CPU Unit where
the data is to be restored, the data in the EM bank areas in the simple backup file will be
restored, but forced status will not be restored. In addition, EM banks that are not in the simple
backup file will retain their values from before the restoration.

backed up from the Memory Card backup
function supported by the Unit or the
DeviceNet Configuration (Ver. 2.@), there
is no file compatibility.)
