Conditions For Restoring Ethercat Slave Data - Omron NJ-series User Manual

Controller status
Slave disconnected
for "Disconnect" des-
ignation in network
configuration
Slave Initialization Error
*1 EtherCAT Slave Backup Failed events are recorded in the event log.
*2 EtherCAT Slave Restore Operation Failed events are recorded in the event log.
*3 The verification results will show differences.
*4 This refers to the following errors: Duplicate Slave Node Address, Network Configuration Information Error,
Network Configuration Error, Slave Initialization Error, Network Configuration Verification Error for Operation
Setting of "Stop", and Link OFF Error.
*5 This refers to the following errors: Network configuration mismatch with configuration when the backup was
performed (incorrect connection ports for slaves on branched networks are treated as a mismatch) and net-
work configuration information mismatch with actual network configuration (incorrect connection ports for
slaves on branched network are treated as a match).
*6 For a CPU Unit with unit version 1.04 or later and Sysmac Studio version 1.05 or higher, data for disabled
slaves is also covered by the backup functions. Data for disabled slaves is not backed up for other versions.

Conditions for Restoring EtherCAT Slave Data

The following conditions must be met before you can restore the backup data to the EtherCAT slaves.
• The backup files must contain the EtherCAT slave data.
• The Network Configuration Information must match the actual network configuration where data is
being restored.
• The revision values that are preset in the EtherCAT slaves must match. The conditions used to evalu-
ate the match are based on the Revision Check Method in the backup file. Even if you set the Revi-
sion Check Method to not check revisions, the restoration operation cannot be performed if the set
revision is greater than the actual revision of the slave. You cannot change the revision values.
• The serial numbers must match if the Serial Number Verification setting in the backup file is set to
verify the serial numbers.
• The node addresses must match if the hardware switches are used to set the node address.
Precautions for Correct Use Precautions for Correct Use
• Cycle the power supply to all of the EtherCAT slaves after you restore data.
• All slaves are disconnected after the data is restored. You must connect the target slaves
again to reset the disconnected slaves.
• If you set the Serial Number Verification setting in the backup file to verify the serial numbers,
the data cannot be restored if you replace any of the hardware for the EtherCAT slaves. In this
case, change the network configuration in Sysmac Studio and download the configuration
data to the new slaves. Then, transfer the slave parameters to restore the slaves to their origi-
nal condition. If the node address is set on the hardware switches, use the same setting as
when the data was backed up.
