FENA-21 2‑Port Ethernet Adapter Module for ABB Drives | ABB

The Original New ABB FENA-21 Ethernet Adapter Module (3ABD0000089109) is a versatile 2‑port communication option for ABB drives, providing seamless integration into industrial Ethernet networks. Supporting three major protocols—PROFINET IO, EtherNet/IP, and Modbus TCP—it enables reliable, high‑speed communication between ABB drives and PLCs, DCS, and SCADA systems. The integrated 2‑port switch supports star, daisy chain, and ring (DLR/MRP) topologies for flexible network architecture. With an embedded web server for remote diagnostics and parameterization, the FENA‑21 simplifies drive commissioning and maintenance, making it a future‑ready solution for modern automation systems.

Core Engineering Highlights:
Triple protocol support: PROFINET IO, EtherNet/IP, and Modbus TCP | 2 x RJ45 ports with integrated switch (10/100 Mbps, auto‑negotiation) | Supports star, daisy chain, Device Level Ring (DLR), and Media Redundancy Protocol (MRP) topologies | Minimum RPI (Requested Packet Interval): 1 ms | 50 nodes allowed in daisy‑chain topology | Embedded web server for diagnostics and configuration | Hot‑swappable installation | Powered directly via the host drive interface | IP20 protection
