1-1 The NJ-series Controllers
The SYSMAC NJ-series Controllers are next-generation machine automation controllers that provide
the functionality and high-speed performance that are required for machine control. They provide the
safety, reliability, and maintainability that are required of industrial controllers.
The NJ-series Controllers provide the functionality of previous OMRON PLCs, and they also provide
the functionality that is required for motion control. Synchronized control of I/O devices on high-speed
EtherCAT can be applied to safety devices, vision systems, motion equipment, discrete I/O, and more.
OMRON offers the new Sysmac Series of control devices designed with unified communications speci-
fications and user interface specifications. The NJ-series Machine Automation Controllers are part of
the Sysmac Series. You can use them together with EtherCAT slaves, other Sysmac products, and the
Sysmac Studio Automation Software to achieve optimum functionality and ease of operation. With a
system that is created from Sysmac products, you can connect components and commission the sys-
tem through unified concepts and usability.
Standard-feature EtherCAT Control Network Support
All CPU Units provide an EtherCAT master port for EtherCAT communications. EtherCAT is an
advanced industrial network system that achieves faster, more-efficient communications. It is based
on Ethernet. Each node achieves a short fixed communications cycle time by transmitting Ethernet
frames at high speed. The standard-feature EtherCAT control network allows you to connect all of
the devices required for machine control (e.g., I/O systems, Servo Drives, Inverters, and machine
vision) to the same network.
Support for EtherCAT Slave Terminals
You can use EtherCAT Slave Terminals to save space. You can also flexibly build systems with the
wide variety of NX Units.
