11-7-2 Application
You can use this function in the following cases.
• When it is dangerous to stop the entire EtherNet/IP Slave Terminal all at once
• To continue the operation of the EtherNet/IP Slave Terminal until the system can be stopped safely
through the user program or user operation
• To not stop all devices, i.e., to continue operation for only some devices
This section describes fail-soft operation in detail.
The following table describes the operation of an EtherNet/IP Slave Terminal when the EtherNet/IP
Slave Terminal is used with and without fail-soft operation.
Except for the I/O refreshing, the operation when an error occurs for the EtherNet/IP Slave Terminal is
the same regardless of whether fail-soft operation is used. Specifically, error notification is provided and
errors are recorded in the event log. Also, the indicators will show the error.
 Using Fail-soft Operation
To enable fail-soft operation, use the Support Software to set the Fail-soft Operation Setting in the
Unit operation settings for the EtherNet/IP Coupler Unit to Fail-soft operation. After you change the
setting, always transfer the Unit operation settings to the EtherNet/IP Coupler Unit. For the Unit
operation settings of the EtherNet/IP Coupler Unit and editing procedures, refer to 9-2-4 Unit Opera-
tion Settings on page 9-22. Refer to 9-3 Transferring and Comparing Settings on page 9-28 for the

 Not Using Fail-soft Operation
To disable fail-soft operation, use the Support Software to set the Fail-soft Operation Setting in the
Unit operation settings for the EtherNet/IP Coupler Unit to Stop. The default setting is Stop.
After you change the setting, always transfer the Unit operation settings to the EtherNet/IP Coupler
Unit. For the Unit operation settings of the EtherNet/IP Coupler Unit and editing procedures, refer to
9-2-4 Unit Operation Settings on page 9-22. Refer to 9-3 Transferring and Comparing Settings on
