1761-NET-ENI Replacement: DF1 to EtherNet/IP Gateway Guide
A reliable 1761-NET-ENI replacement is essential for industrial plants maintaining legacy Allen-Bradley controllers. The original 1761-NET-ENI module from Rockwell Automation was designed to bridge DF1 RS-232 serial networks to EtherNet/IP for MicroLogix, SLC 500, and PLC-5 systems, but has since been discontinued.
Selecting an industrial 1761-NET-ENI replacement eliminates the strict 4-socket connection bottleneck of legacy modules. The ANC-100e gateway allows plant engineers to keep existing SLC 500 and MicroLogix hardware intact while providing modern, high-speed EtherNet/IP connectivity for SCADA, HMIs, and remote programming.
1761-NET-ENI Replacement Features & Capabilities
- No Connection Throttling: Eliminates the historic 4-connection bottleneck, supporting high-speed SCADA polling and engineering workstations simultaneously.
- Seamless HMI & SCADA Integration: Bridges legacy DF1 serial and DH+ networks to Ignition, Kepware, FactoryTalk View, AVEVA Wonderware, and OPC UA/DA architectures.
- Preserve Working Infrastructure: Extend the operational lifespan of reliable SLC 5/03, SLC 5/04, MicroLogix, and PLC-5 processors without ladder logic rewrites.
- Industrial DIN-Rail Mounting: Rugged form factor built for high-temperature control cabinets with 24V DC industrial power.
- Fast Browser Configuration: Full configuration and diagnostics accessible directly through standard web browsers without special setup utilities.
