• Omron NX Safety Product Overview

Integrated safety into machine automation

Our Sysmac automation platform integrates a safety solution within our One Connection and One Software concept. One Connection is achieved through the use of Safety over EtherCAT - FSoE - protocol. The One software is achieved by using Sysmac Studio for configuration, programming and maintenance. The NX Safety System consists of safety controller and safety I/O units. Both the safety controller and safety I/O can be freely distributed in an I/O rack throughout the network when used with an NJ Machine Automation Controller on an EtherCAT network, mixing them in any combination with standard NX I/O.

  • The safety controller meets Category 4, PLe according to the EN ISO 13849-1 and SIL3 according to the IEC 61508
  • Up to 8 safety input points per unit
  • Safety Function Blocks conforming with IEC 61131-3 standard programming
  • PLCopen Function Blocks for safety Integration in one software, Sysmac Studio
This safety controller uses the same hardware used on EtherCAT networks and EtherNet/IP connectivity for monitoring of status and information Sysmac Studio Software Full License supports EtherCAT integration and EtherNET/IP Stand-alone configuration of the NX-S modular safety I/O. Sysmac Studio Safety License supports only EtherNET/IP Stand-alone configuration of the NX-S modular safety I/O


NX-S Series can now be used in a stand-alone configuration as a powerful, modular and easily commissioned safety controller which, due to its scalability, can be efficiently adapted to the requirements of a wide variety of safety applications. Thanks to this modular and expandable hardware, the compact safety controller grows with its task slice-by-slice – right up to the highest safety level. You can grow up to 256 I/O points in one single Safety CPU. The design of safe system solutions is thus considerably simplified
