 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.
 Achieving a Safety Subsystem on EtherCAT
You can use NX-series Safety Control Units to integrate safety controls in a sequence and motion
control system as a subsystem on EtherCAT.
 Standard-feature Two EtherNet/IP Communications Ports
All CPU Units provide two EtherNet/IP ports for EtherNet/IP communications.
EtherNet/IP is a multi-vendor industrial network that uses Ethernet. You can use it for networks
between Controllers or as a field network. The use of standard Ethernet technology allows you to
connect to many different types of general-purpose Ethernet devices.
 Standard-feature SD Memory Card Slot
You can access an SD Memory Card that is mounted in the CPU Unit from the user program.
 Highly Reliable Hardware
The NX-series Controllers provide the hardware reliability and RAS functions that you expect of a
PLC.
 Parallel Execution of Tasks with a Multi-core Processor
The NX701-  CPU Unit has a multi-core processor that can execute more than one task
in parallel. This enables high-speed control of even large-scale devices.
 Integrated Sequence Control and Motion Control
An NX-series CPU Unit can perform both sequence control and motion control. You can simultaneously
achieve both sequence control and multi-axes synchronized control. Sequence control, motion control,
and I/O refreshing are all executed in the same control period.
The same control period is also used for the process data communications cycle for EtherCAT. This
enables precise sequence and motion control in a fixed period with very little deviation.
 Multitasking
You assign I/O refreshing and programs to tasks and then specify execution conditions and execu-
tion order for them to flexibly combine controls that suit the application.
 Programming Languages Based on the IEC 61131-3 International Standard
The NX-series Controllers support language specifications that are based on IEC 61131-3. To these,
OMRON has added our own improvements. Motion control instructions that are based on PLCo-
pen
®
standards and an instruction set (POUs) that follows IEC rules are provided.
