Introduction to the System Configurations

The NX Series supports the following system configurations.
 Basic System Configurations
The NX-series basic configurations include the EtherCAT network configuration and the Support
Software.
• EtherCAT Network Configuration
You can use the built-in EtherCAT port to connect to EtherCAT Slave Terminals, to general-purpose
slaves for analog and digital I/O, and to Servo Drives and encoder input slaves. An EtherCAT network
configuration enables precise sequence and motion control in a fixed cycle with very little deviation.
• Support Software
The Support Software is connected to the peripheral USB port on the CPU Unit with a commer-
cially available USB cable. You can also connect it through an Ethernet cable that is connected to
the built-in EtherNet/IP port.
Refer to 3-4-2 Connection on page 3-15 for details on the connection configuration of the Support
Software.

Precautions for Correct Use
NX Units should be connected to Slave Terminals. The NX bus connector of the CPU Unit is pro-
vided for future expansion so that it cannot be used to connect any NX Unit.
Additional Information
You can connect the Sysmac Studio directly to the Communications Coupler Unit to set up the Slave
Terminal. Refer to the NX-series EtherCAT Coupler Units User's Manual (Cat. No. W519) for details.
