*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

*1. This is the maximum number of Safety I/O connections that can be set to this Unit. The value is the total number of CIP Safety originator connections, CIP Safety target connections, and FSoE master connections.
*2. The cable length for the Units (Communication Control Unit and Power Supply Unit for NX Units) that supply power to the corresponding Unit must be up to 20 m.
*3. Only NX102 CPU Units and Communication Control Units can be connected. NX1P2 CPU Units or Communications Coupler Units cannot be connected.
Refer to your local OMRON website for function specifications of the Safety Control Unit.
This section describes the combinations that can be used of the unit versions of the Safety Control Unit and NX102 CPU unit, and the version of the Sysmac Studio.
