is written to the Memory Card. The data is backed up separately for each Unit
and Board.
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 10 Hex
Special I/O Units: Unit 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.
The following Units and Boards are supported as of July 2001.
Note Data from the Units and Boards listed above will be automatically backed up
for the simple backup operation. There is no setting available to include or
exclude them.
Procedure
The procedure for the simple backup operation is the same regardless of
whether or not data is being backed up from specific Units and Boards
(including writing, reading, and comparing).
