1 Introduction to NJ-series Controllers
Sysmac Studio Automation Software
The Sysmac Studio provides an integrated development environment that covers not only the Con-
troller, but also covers peripheral devices and devices on EtherCAT. You can use consistent proce-
dures for all devices regardless of the differences in the devices. The Sysmac Studio supports all
phases of Controller application, from designing through debugging, simulations, commissioning,
and changes during operation.
A Wealth of Simulation Features
The many simulation features include execution, debugging, and task execution time estimates on a
virtual controller.

Introduction to the System Configurations
The NJ Series supports the following system configurations.
Basic System Configurations
The NJ-series basic configurations include the EtherCAT network configuration, CJ-series Unit con-
figuration, 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 devi-
ation.
CJ-series Unit Configuration
In addition to the EtherCAT network, you can mount CJ-series Basic I/O Units and Special Units. CJ-
series Units can be mounted both to the CPU Rack where the CPU Unit is mounted and to Expan-
sion Racks.
Support Software
The Support Software is connected to the peripheral USB port on the CPU Unit with a commercially
available USB cable. You can also connect it through an Ethernet cable that is connected to the
built-in EtherNet/IP port.
Refer to 3-7-2 Connection for details on the connection configuration of the Support Software.
