This function can be used to back up data for the entire PLC, including the
CPU Unit, DeviceNet Units, Serial Communications Units/Boards, etc. It can
also be used for Unit replacement.
The data from each Unit and Board is stored in the Memory Card using the
following file names: BACKUP@@.PRM. Here, "@@" is the unit address of the
Unit or Board in hexadecimal.
Note Unit addresses are as follows:
CPU Bus Units: Unit number + 10 hex
Special I/O Units: Unit number + 20 hex
Inner Board: E1 Hex
These files are also used when reading from the Memory Card or comparing
Memory Card data.
For Unit and Board data to be backed up, the Unit/Board must also support
the backup function. Refer to the operation manual for the Unit/Board for
details on support.
