Introduction to the System Configurations

The NX-series Controller NX102 supports the following system configurations.
Basic System Configurations
The NX-series Controller NX102 basic configurations include the EtherCAT network configuration, NX
Unit configuration, and the Support Software.
• EtherCAT Network Configuration
You can use the built-in EtherCAT port on the CPU Unit 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.
• NX Unit configuration
The CPU Unit can be connected with up to 32 NX Units (NX-££££££) including NX-series Digi-
tal I/O Units, Analog I/O Units, and other I/O Units. These NX Units can be flexibly combined with
the CPU Unit and configure a CPU Rack to support various applications.
• Support Software
You can connect the Support Software through an Ethernet cable that is connected to the built-in
EtherNet/IP port 1 or 2 in the CPU Unit.
Refer to 3-5-2 Connection on page 3-19 for details on the connection configuration of the Support
Software.
