Replacing Units Using the Simple Backup Function
Note
1,2,3...
The simple backup function can be used to replace Units when using a CS1-
H, CJ1-H, CJ1M, or CS1D CPU Unit.
1. The Memory Card must be installed in the CPU Unit to enable the simple
backup function.
2. The simple backup function is supported by CS1W-FLN22 and CJ1W-
FLN22 FL-net Units. The simple backup function cannot be used with
CS1W-FLN02 or CS1W-FLN12. Refer to Replacing CS1W-FLN12 with
CS1W-FLN22 for details on replacing CS1W-FLN02 and CS1W-FLN12
FL-net Units.
1. Turn ON the power to the CPU Unit and install the Memory Card.
2. Turn ON pin 7 of the DIP switch on the front of the CPU Unit.
3. Press the Memory Card power supply button for 3 seconds to write the set-
up data to the Memory Card.
The data will start being written to the Memory Card, during which time the
MCPWR indicator on the front of the CPU Unit will be lit. The indicator will
turn OFF after writing has completed normally, at which time all the setup
data including the CPU Unit's ladder program will be saved as a file in the
Memory Card in the CPU Unit.
4. Turn OFF the power to the CPU Unit and replace the FL-net Unit.
5. Set the rotary switches on the front of the new FL-net Unit (CPU Bus Unit
number and node address) to the same settings as the previous FL-net
Unit.
6. Make sure that pin 7 of the DIP switch on the front of the CPU Unit is turned
ON to enable the setup data to be read from the Memory Card, and then
turn ON the power to the CPU Unit. The FL-net Unit will start reading the
data from the Memory Card, during which time the MCPWR indicator on
the front of the CPU Unit will be lit. The indicator will turn OFF after reading
has completed normally, at which time all the setup data including the CPU
Unit's ladder program will be read to each Unit from the Memory Card in
the CPU Unit.
7. Turn OFF the power to the CPU Unit and turn OFF pin 7 of the DIP switch
on the front of the CPU Unit.
8. Turn ON the power to the CPU Unit and check the indicator display and
status of the FL-net Unit.
Note For details on the simple backup function (e.g., procedures, file configuration,
indicator displays), refer to the section on simple backup operation in the
SYSMAC CS/CJ-series Programmable Controllers Programming Manual
(W394).
