Product Introduction
The ABB NE871 3BSE080240R1 is an industrial Ethernet router and firewall designed for ABB System 800xA network architectures. It provides three 10/100/1000 Mbps RJ-45 ports and Layer 3 routing, allowing network areas to be separated while maintaining controlled communication between them. ABB also specifies RNRP support for redundant network architectures.
For plant engineers, the important point is that NE871 is more than an Ethernet switch. It performs routing and firewall functions and is intended for network segmentation, including connections toward plant networks and DMZs. The wide 16–60 VDC input range and DIN-rail construction also suit control-system cabinets where redundant DC power and compact installation are required.

Application Scenarios & Field Pitfalls
Engineering Pain Point
A failed industrial router can affect an entire control network even when every controller and I/O station remains operational. The mistake is often treating the replacement as a conventional Ethernet switch. NE871 is a Layer 3 router with firewall functions and RNRP support. Its routing configuration, redundancy behavior, and security rules are part of the control-system design.
Typical Applications
- Process Automation — Segmenting System 800xA control networks from plant-level Ethernet networks.
- Oil & Gas — Connecting control-system network areas while maintaining defined security boundaries.
- Power Generation — RNRP-based redundant network architectures for DCS infrastructure.
- Industrial Manufacturing — Controlled routing between client-server networks, automation networks, and DMZ environments.
Technical Pitfalls to Avoid
- Do not substitute NE871 with an ordinary managed switch.
ABB classifies NE871 as a router with Layer 3 routing and firewall capability. A switch with similar port counts does not reproduce those functions. - Verify the RNRP architecture before replacement.
RNRP is specifically used to support physically separate redundant networks in 800xA environments. Confirm the existing network topology and configuration before putting a replacement router into service. - Check power redundancy and cabinet wiring.
supports redundant power and operates from 16–60 VDC. Confirm both supply paths, alarm wiring, and cabinet termination before commissioning. - Do not assume every 800xA network device is interchangeable.
The related NE870, for example, has eleven Ethernet ports, while has three Gigabit RJ-45 ports. The two products share routing/firewall functions but have different physical network interfaces.
