Introduction to the System Configurations
The NX-series Controller NX1P2 supports the following system configurations.
Basic System Configurations
The NX-series Controller NX1P2 basic configurations include the EtherCAT network configuration, NX
Unit configuration, and the Support Software.
• EtherCA
T 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 devi-
ation.
• NX Unit configuration
The CPU Unit can be connected with up to eight NX Units (NX-££££££) including NX-series
Digital 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 in the CPU Unit.
Refer to 3-7-2 Connection on page 3-33 for details on the connection configuration of the Support
Software.
