Backing Up CompoNet Master Unit Setup Files to Memory Card

The CPU Unit's simple backup function can be used when either a CS1W-
CRM21 CompoNet Master Unit is mounted to a CS1-H CPU Unit, or a CJ1W-
CRM21 CompoNet Master Unit is mounted to a CJ1-H CPU Unit. This func-
tion enables all setup data in the internal non-volatile memory (EEPROM) of
the CompoNet Master Unit, as well as all data in the CPU Unit, to be automat-
ically backed up to, restored from, or compared with a file in a Memory Card
mounted in the CPU Unit.
When all the setup data in the CompoNet Master Unit is written to the Mem-
ory Card using a simple backup operation, it is backed up as a Unit/Board
backup file in the Memory Card under the file name BACKUP@@.PRM.
Note The blanks in the backup file name are replaced with the unit ad-
dresses of a CompoNet Master Unit, which is the unit number of a
Special I/O Slave Unit + 20 hex.
This backup file is also used when downloading data from or comparing data
with a file in the Memory Card.

All setup data
Note The data restoration by the simple backup function in CS1W-CRM21 or
CJ1W-CRM21 CompoNet Master Units is not downwardly compatible. The
backed up data can be restored only in CompoNet Master Units of the same
or later unit versions.
Use the simple backup function to create a backup file of data for the entire
PLC, including the CPU Unit and Serial Communications Units/Boards, or
when replacing all the Units.
Set the DIP switch on the front panel of the CPU Unit, as shown in the follow-
ing table, and press down the Memory Card Power Supply Switch for 3 sec-
onds.
