NX-series Safety Control Unit User’s Manual (Z930)
1-2 System Configuration and Configura-
tion Devices
The safety control system operates on the EtherCAT network.
You combine the EtherCAT Master Function Module in the NJ/NX-series CPU Unit with the EtherCAT
slave functionality in an NX-series EtherCAT Coupler Unit to build a safety control system.
The Safety CPU Unit serves as the FSoE master to control Safety I/O Units that serve as FSoE slaves.
*1
As shown in the above figure, the Safety CPU Unit can be used to control not only the Safety I/O Units that
are mounted to the same EtherCAT Slave Terminal, but also it can control Safety I/O Units that are mounted
to other EtherCAT Slave Terminals through the EtherCAT network. You can use only one Safety CPU Unit on
each EtherCAT network.
*1. The connectivity of FSoE communications has been confirmed between OMRON NX-series Safety Control
Units. Preparations for the Safety over EtherCAT Test Center were underway by the EtherCAT Technology
Group as of September 2013.
