Overview of Safety Control Unit
The NX-series Safety Control Units are part of the lineup of Sysmac devices. They are used to exe-
cute safety controls. Safety Control Units are classified as NX Units and they are used connected to
an NX-seriess, EtherCAT Coupler Unit or EtherNet/IP Coupler Unit.
You use the integrated development environment that is provided by the Sysmac Studio Automation
Software to build the safety control system, and perform all settings, programming, and debugging of
the Safety Control Unit.
Safety Control System on CPU Rack or EtherCAT Network
The NX-series Safety Control Units can be connected to the following units.
*1
• NX-series CPU Unit
*2
•
NX-series EtherCAT Coupler Unit
When using both the CPU Unit and EtherCAT Coupler Unit, you can integrate the installation, wiring,
and setting methods of the NX Unit, which will enable design costs to be reduced.
These Units achieve safety controls on an CPU Rack or EtherCAT network when they are used in a
sequence and motion control system that is based on the NJ/NX-series Machine Automation Control-
ler.
*1. Only one Safety CPU Unit can be used in this system.
*2. Refer to the user's manual of the CPU Unit to be used for details on whether the Safety Control Unit can be
connected to the CPU Unit to be used.
The Safety Control Unit connected to a CPU Unit performs I/O communications with the CPU Unit.
The Safety Control Unit
connected to an EtherCAT Coupler Unit performs remote I/O communications
with the EtherCAT master through the EtherCAT Coupler Unit. Both methods support the FSoE (Safe-
ty over EtherCAT) protocol through each communication and perform safety I/O communications be-
tween the FSoE master and slaves through the CPU Unit that has a built-in EtherCAT master. This
allows you to use safety process data communications and standard process data communications on
the same EtherCAT network through the NX bus of the CPU Unit that has a built-in EtherCAT master.
Additional Information
• NX102 CPU Units support connection of NX-SL££££ Units, NX-SI££££ Units, and NX-
SO££££ Units.
• NX-series
EtherCAT Coupler Units support connection of NX-SL3£££ Units, NX-SI££££
Units, and NX-SO££££ Units. It does not support connection to NX-SL5£££ Units.
