13-2 Simple Backup Function
Overview
Note
• If there is a faulty contact, try wiping the contact with a clean, lint-free
cloth dampened with alcohol.
To prevent electric shock when replacing a Unit, always stop communications
in the network and turn OFF the power supplies to all of the nodes before
removing the faulty Unit.
After a Unit has been replaced, verify that the following steps have been made
correctly.
• Set the node address and unit number.
• Connect the Ethernet cable.
• Set the configuration data (parameter settings) again and download them.
The simple backup function can be used to back up not only all of the data in
the CPU Unit, but also all of the data stored in memory in the EtherNet/IP Unit
or data for the built-in EtherNet/IP port. All of this data will automatically be
backed up to the Memory Card.
The simple backup function can be used for the following EtherNet/IP Units
and built-in EtherNet/IP port.
• CS-series EtherNet/IP Unit (CS1W-EIP21) mounted to a CS1D/CS1-
H CPU Unit
• CJ-series EtherNet/IP Unit (CJ1W-EIP21) mounted to a CJ1-H/CJ1M/
CJ2H-CPU@@-EIP CPU Unit
• A built-in EtherNet/IP port on a CJ2H-CPU@@-EIP/CJ2M-CPU3@
CPU Unit
When the EtherNet/IP Unit's setup data is written to the Memory Card using a
simple backup operation, it is stored in the Memory Card as a Unit/Board
backup file with the file name BACKUP@@.PRM. (The @@ digits in the
backup file name indicate the unit address of the EtherNet/IP Unit or built-in
EtherNet/IP port, which is the unit number + 10 hex.)
This backup file is also used when reading data from the Memory Card or
comparing data with a file in the Memory Card.
