2 Part Names and Slave Settings
Backing Up and Restoring Parameters
The Sysmac devices use an option in the version-1.0.1 ESI specifications to enable backing up and
restoring the backup parameters that are specified in the ESI files in non-volatile memory in the slaves.
You can back up and restore the backup parameters that are stored from the Sysmac Studio.
This makes it easy to set slaves when they are replaced.
Additional Information
• If you use slaves from other manufacturers, obtain the slave information files that are compli-
ant with the version-1.0.1 ESI specifications from the slave manufacturers.
• Refer to 9-4-3 Backing Up Settings for the procedure to back up slave data from the Sysmac
Studio.
• Refer to 9-4-4 Restoring Settings for the procedure to restore slave data from the Sysmac Stu-
dio.
• Refer to A-3 Multi-vendor Environments for information on ESI.
Saving Node Address Settings
Each Sysmac device stores its own node address setting in non-volatile memory within the slave.
This allows the master to identify slaves on the network.
The node addresses are set as given below depending on the type of slave.
• Slaves with Hardware Switches
0: The node address is set from the Sysmac Studio.
Not 0: The setting on the hardware switches is used.
• Slaves without Hardware Switches
The node address is set from the Sysmac Studio.
Precautions for Correct Use Precautions for Correct Use
• Set a node address for every slave so that the slaves can be identified on the EtherCAT net-
work. Do not assign the same node address more than once.
• If you connect slaves from other manufacturers to the NJ/NX-series EtherCAT master, set the
node addresses for them from the Sysmac Studio. (The NJ/NX-series EtherCAT master recog-
nizes the value that is stored at address 0x0012 in the EtherCAT slave controller of the slave
as the node address.)
• For OMRON slaves that are not Sysmac devices, set the node addresses on the hardware
switches. If the node address switches are set to 0, a Network Configuration Verification Error
occurs.
Additional Information
• Refer to 2-2 Setting the Node Addresses of the EtherCAT Slaves or the manuals for each
slave for the procedure to set the node addresses.
• Refer to 5-4-2 Setting EtherCAT Slaves for information on setting node addresses with the
Sysmac Studio.
