This is the name of the EtherCAT Coupler Unit.
Default value: E *** (* is a serial number from 001).
The default value is automatically generated based on the node address.
Setting range: Text string
Model name This is the model of the EtherCAT Coupler Unit.
Product name This is the product name of the EtherCAT Coupler Unit.
Revision This is the revision number of the EtherCAT Coupler Unit.
Node Address
Yes
This is the node address.
The default value is set automatically when a slave is added.
Setting range: 1 to 192
Enable/Disable

• Disabled: The Slave Terminal will not operate.
*1
Default setting: Enabled
Serial Number This is the serial number of the EtherCAT Coupler Unit.
Default: 0x00000000 (when offline)
The value is updated to the serial number of the physical slave when you select
Get Slave Serial Numbers from the menu for the master.
A Network Configuration Verification Error occurs if the serial number on the Sys-
mac Studio and the serial number of the physical slave do not agree when the
Serial Number Check Method in the master settings is set to Setting = Actual
device.
Refer to the NJ-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No.
W505) for details on how to find the serial number of your Unit.
PDO Map Set-
tings
This is a list of the valid PDOs. The PDO mappings for the EtherCAT Slave Ter-
minal depend on the I/O allocations to the Slave Terminal. The PDO mappings
are not displayed because you do not directly edit the PDO mappings for the
EtherCAT Coupler Unit.
Enable Distrib-
uted Clock
Yes
This setting enables or disables the distributed clock.
The I/O refresh method for the mounted NX Unit is as follows:
• If the distributed clock is enabled: Synchronous I/O refreshing
• If the distributed clock is set to disabled: Free-Run refreshing
Default setting: Enabled
Reference
Clock
This setting tells whether the slave provides a reference clock. This setting indi-
cates having a reference clock because the EtherCAT Coupler Unit has its own
reference clock.
Setting Param-
eters
Yes
This setting affects the parameters that are automatically set by the EtherCAT
master when EtherCAT communications start or when a slave is reconnected.
Backup Param-
eter Settings
This setting is for backup parameters. The backup parameters for the EtherCAT
Coupler Unit cannot be set here. Set the backup parameters in the Unit operation
settings.
