and Wiring the
Slave Terminal Setting the
Node Address Set the node address of the EtherCAT Coupler Unit with the
hardware switches. You can also use the Sysmac Studio to
set the node address with software settings. To use software
settings, set the hardware switches to 000, and then mount
and wire the EtherCAT Coupler Unit. When you go online in
step 3, follow the procedure to automatically create the
EtherCAT network configuration from the actual network
devices with the compare and merge operation. This sets the
node address to the software setting. 4-3 Hardware

Making Set-
tings as an
EtherCAT
Slave Creating the
EtherCAT Net-
work Configura-
tion and Making
Settings as an
EtherCAT Slave Create a project in the Sysmac Studio.
Create the EtherCAT network configuration offline.
Specifically, register the EtherCAT Coupler Unit in the net-
work configuration. Then, make the settings for the EtherCAT
Coupler Unit as an EtherCAT slave. Set the node address of
the EtherCAT Coupler Unit to the node address set in step 2.
Set other parameters as required.
If you want to use the compare and merge operation to auto-
matically create the EtherCAT network configuration online
based on the actual devices that are connected to the net-
work, you must use step 8 first to go online. After the network
configuration is created automatically, go offline and set the
other parameters. 9-2-2 Settings as
