1-1-2 Introduction to the System Configurations
The NX-series NX1P2 Controller supports the following system configurations.
The NX-series NX1P2 Controller 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 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 net-
work configuration enables precise sequence and motion control in a fixed cycle with very little devia-
tion.
• NX Unit Configuration
The CPU Unit can be connected with up to eight NX Units (NX-) including NX-series Dig-
ital 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
The Support Software is connected to the built-in EtherNet/IP port on the CPU Unit with an Ethernet
cable.
Refer to 3-7-2 Connection on page 3-34 for details on the connection configuration of the Support
Software.
