Overview
The Allen-Bradley 22-COMM-E is a compact EtherNet/IP communication adapter designed to integrate PowerFlex 4, 40, and 400 AC drives into EtherNet/IP networks. This adapter mounts internally into the drive’s communication slot, providing direct high-speed Ethernet connectivity to PLC controllers, HMIs, and other industrial devices on your network.
Key Features
- Supports 10 or 100 Mbps communication with full and half-duplex operation
- Internal mounting design for compact integration into PowerFlex drives
- Up to 30 simultaneous TCP connections for distributed control applications
- Handles up to 400 total I/O packets per second with minimum 5 ms RPI support
- Built-in web interface for diagnostics, configuration, and real-time status monitoring
- Email notification capability for drive faults and communication events
- Four onboard status LEDs for quick network, module, and DSI health verification
- DIP switch configuration for IP address settings (DHCP or static) and network speed

Typical Applications
The 22-COMM-E is ideal for applications requiring real-time coordination across multiple drives on a single EtherNet/IP network:
- Coordinated multi-drive conveyor and packaging systems
- Manufacturing lines requiring synchronized motor control
- Distributed drive networks in automotive and food processing
- Integration of legacy PowerFlex drives into modern Ethernet-based control architectures
- Remote monitoring and diagnostics of drive performance over standard industrial networks
- Systems where daisy-chaining of up to 5 drives per adapter reduces network infrastructure costs
