Manipulating Files Section 5-2
Application
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.
Unit/Board Backup Files
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.
Applicable Units and Boards
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.
