Overview
The Allen-Bradley 22-COMM-E is an EtherNet/IP adapter card designed for seamless integration of PowerFlex component-class drives into Ethernet-based industrial automation systems. This compact communication module installs directly into the drive’s communication slot via a ribbon cable, enabling real-time control and monitoring of drives over standard Ethernet networks. It is designed for PowerFlex 4, 40, and 400 AC drives and installs directly into the drive’s communication slot to enable high-speed Ethernet connectivity.
Key Features
- Dual Data Rate Support: Allows drives to communicate over EtherNet/IP at speeds of 10 or 100 Mbps, supporting both full- and half-duplex modes
- Multi-Drive Capability: In single-drive mode, the adapter accommodates one drive per node, while in multi-drive mode, it can manage up to five drives per node
- Built-In Diagnostics: Includes built-in diagnostic web pages for drive and adapter information, configuration options, and status monitoring, with four onboard status LEDs for quick network and module health verification
- Network Performance: Provides up to 30 simultaneous TCP connections, handles up to 400 total I/O packets per second, and supports a minimum Requested Packet Interval (RPI) of 5 ms
- PLC Integration: Fully compatible with standard Ethernet tools such as BOOTP/DHCP utilities and integrates seamlessly with Allen-Bradley PLCs via EtherNet/IP
Technical Specifications
- Communication Protocol: EtherNet/IP
- Network Interface: RJ-45 for Ethernet connections
- Data Rates: 10/100 Mbps
- Duplex Operation: 10 Mbps Full Duplex, 10 Mbps Half Duplex, 100 Mbps Full Duplex, and 100 Mbps Half Duplex
- Power Requirements: 24V DC (typically powered by the drive)
- Electrical Consumption: 350 mA at 5 VDC supplied through the drive
- Mounting Type: Internal Mount
- Dimensions: 10.2 cm x 10.2 cm x 5.1 cm
- Weight: 2.3 kg
- Status Indicators: PORT, MOD, NET A, NET B for module and network status monitoring
Typical Applications
The adapter is primarily used in industrial automation environments where centralized drive control is essential, such as manufacturing plants, conveyors, pumps, and HVAC systems. It is commonly deployed in facilities requiring coordinated motor control across multiple PowerFlex drives using a single EtherNet/IP network backbone.
