Precautions for Correct Use
• The sample programming shows only the portion of a program that uses the function or func-
tion block from the library.
• When using actual devices, also program safety circuits, device interlocks, I/O with other
devices, and other control procedures.
• Create a user program that will produce the intended device operation.
• Check the user program for proper execution before you use it for actual operation.
This is an example of programming for backing up and then restoring parameters for the E3NW Unit at
node address 1.
• The backup file is created in the TestDir directory.
• The backup file is write-protected (default).
• The timeout time is 2 s (default).
1
Make sure that the target slave is in a state that allows communications, that SD Memory Card
Ready Flag is TRUE, and that SD Memory Card Write Protected Flag is FALSE (not write pro-
tected). Also confirm that the same instance is not being executed and that parameters are not
being restored to the same node.
2
Execute BACKUP_E3NW_instance.
1
Make sure that the target slave is in a state that allows communications, that SD Memory Card
Ready Flag is TRUE, that the same instance is not being executed, and that parameters are not
being backed up from the same node.
2
Execute RESTORE_E3NW_instance.

Code
*1
SDO Abort Error The cause of this error
depends on the specifications
of the EtherCAT slave.
Refer to the manual for the Eth-
erCAT slave and correct the
problem.
