*1. The FSoE protocol was certified for applications in which OMRON FSoE devices are connected to each other.
For compatibility with FSoE devices other than OMRON FSoE devices, the customer must validate FSoE communications.
*2. Only NX-SL5500/5700 have obtained IEC 61131-6 and FSPC certifications.

The NX-series Safety Control Units allow you to build a safety control system that meets the following standards.
• Requirements for SIL 3 (Safety Integrity Level 3) in IEC 61508, IEC/EN 62061, (Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems)
• Requirements for PLe (Performance Level e) and for safety category 4 in EN ISO13849-1
