NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (W505)
• You can back up the EtherCAT slave settings for any EtherCAT slave that is connected to the
network (i.e., whenever the _EC_EntrySlavTbl[] (Network Connected Slave Table) system-
defined variable is TRUE) either before of after the disconnection command is sent to the Eth-
erCAT slave.
• You can also set the EtherCAT drive slaves from the EtherCAT Drive Tab Page. Back up the
settings information from the EtherCAT Drive Tab Page. Refer to the Sysmac Studio Version 1
Operation Manual (Cat. No. W504) for the applicable EtherCAT drive slaves.
• You do not need to back up the settings to replace an EtherCAT slave that does not have
backup parameters.
After you replace the EtherCAT slave, you restore the settings that you backed up before you replaced
the slave. The backup parameters that were backed up are restored to the EtherCAT slave.
1
Click the Edit Backup Parameter Settings Button in the EtherCAT Slave Setting Tab Page.
The Backup Parameter Settings Tab Page is displayed.
2
Click the Transfer to Slave Button.
All of the backup parameters that are stored in the EtherCAT slave and displayed in the list are
downloaded to the EtherCAT slave.
3
Click the Compare Button.
Check to be sure that you have correctly transferred the backup parameters in step 2.
