NX-series Safety Control Units
NX-SL/SI/SO
Integration of Safety into Machine
Automation Enables Simple,
Flexible System Configuration.
• EN ISO13849-1 (PLe/Safety Category4), IEC 61508 (SIL3) certified.
• One connection using Safety over EtherCAT (FSoE) *protocol
enables flexible configuration by mixing the Safety Units with standard
NX I/O.
• Hardware and safety circuits can be configured using the Sysmac
Studio (Ver. 1.07)
* Safety over EtherCAT (FSoE): The open protocol Safety over EtherCAT (abbreviated with FSoE "FailSafe over EtherCAT") defines a safety
related communication layer for EtherCAT. Safety over EtherCAT meets the requirements of IEC 61508 SIL 3 and enables the transfer of safe
and standard information on the same communication system without limitations with regard to transfer speed and cycle time.
Features
•Integrated safety into machine automation possible by connecting with the NX-series EtherCAT Coupler.
•The Safety CPU Unit controls up to 128 Safety I/O Units.
•4 or 8 points per Safety Input Unit. The 4-point Safety Input Unit can be directly connected with OMRON Non-contact Switches and Singlebeam
Sensors.
•2 or 4 points per Safety Output Unit. The 2-point Safety Output Unit is characterized by large output breaking current of 2.0 A.
•The Safety Units can be freely allocated in any combination with standard NX I/O.
•Compliant with IEC61131-3
•Safety programs can be standardized and reused efficiently by using POUs for design and operation.
