Allen-Bradley 25-COMM-E2P 2 Port Ethernet Communication Adapter

The Allen-Bradley 25-COMM-E2P is a dual-port EtherNet/IP communication adapter designed for PowerFlex 520-series drives. Installed inside the PF520 drive back cover, it adds two independent Ethernet interfaces (ENET1 and ENET2) via two interface connectors that link the Communication card to the drive header, enabling EtherNet/IP networking for PowerFlex control. The two network ports support connections to PLCs, HMIs, remote I/O, and other EtherNet/IP devices, enabling straightforward daisy-chaining and network expansion within PF520 configurations. Documented in Rockwell Automation literature as the PowerFlex 520-series dual-port EtherNet/IP communication option, 25-COMM-E2P, this adapter provides Ethernet/IP communications for real-time drive control and integrated device communication across industrial networks. In typical PF520 deployments, it facilitates coordinated drive operation, monitoring, and remote diagnostics by pairing the PF520 with standard EtherNet/IP-capable equipment through ENET1 and ENET2 networks.
