Allen Bradley 22-COMM-E PowerFlex Ethernet/IP Adapter

Allen-Bradley 22-COMM-E PowerFlex VFD EtherNet/IP Adapter (Ver. 1.007)

The Allen-Bradley 22-COMM-E is an advanced industrial communication adapter designed specifically to link PowerFlex 4-Class variable frequency drives (VFDs) to common EtherNet/IP networks. This interface module operates on firmware version v1.007 and provides high speed peer-to-peer data interchange, real-time control and extensive remote diagnostics over conventional TCP/IP protocols. It is designed to high marine and land-based industrial automation standards, reducing complex wire overhead and allowing smooth connection to Logix-based controllers such as ControlLogix and CompactLogix.

Model Details:

Characteristics

1. High-Speed Network Compatibility: Supports 10/100 Mbps data transfer speeds and auto-negotiation of full- and half- duplex modes over conventional RJ45 connections.
2. Firmware v1.007 Enhancements: Improves duplicate IP address detection prevention when handled via BOOTP/DHCP servers and adds longer diagnostic queues to the web interface.
3. Messaging Flexibility Support for implicit messaging (real-time I/O data) and explicit messaging (configuration, parameter read/writes and PCCC/CIP commands).
4. Direct Drive Flash Support – Enables direct firmware flashing of any PowerFlex drive attached to the adapter architecture.

Industrial & Marine Applications

• Marine propulsion and auxiliary pump motor control loops
• Shipboard HVAC air-handling compressor regulation
• Factory automation material handling lines
• Industrial packaging machinery and automated conveyors
• Distributed municipal water and wastewater treatment skid packages

Marine Engineer Expert’s Guide

Expert Installation Advice: When installing the 22-COMM-E adapter onto PowerFlex 4-class drives in high-vibration marine switchboard environments, ensure the physical DSI connector latch clicks firmly into position. Secure any external CAT5/CAT6 communication lines with strain-relief zip ties close to the chassis to eliminate micro-motion wear on the RJ45 pins caused by hull vibration.

1. (IP Addressing): If deploying units via automated BOOTP servers, firmware v1.007 resolves legacy duplicate IP flag errors, but always hardcode static IP allocations for critical auxiliary machinery loops to guarantee deterministic boot-up times during emergency generator black-start sequences.
2. (Firmware Parity): Always verify that your DriveExplorer or ControlFLASH packages match the device revision tree before executing remote parameter cloning or parameter restores using the HIM CopyCat feature.

Frequently Asked Questions

What is the primary function of the Allen-Bradley 22-COMM-E adapter?

The 22-COMM-E module acts as an internal bridge connecting Allen-Bradley PowerFlex 4-class variable frequency drives to an industrial EtherNet/IP network, permitting centralized control, parameter configuration, and live operational diagnostics.

Does firmware version v1.007 support direct drive flashing?

Yes. Version v1.007 adds specific support for flashing a PowerFlex 4M drive directly through the 22-COMM-E adapter interface or via an auxiliary serial converter loop.

How is the 22-COMM-E module powered during operation?

The adapter derives its operational power (24V DC, 75 mA) directly from the host PowerFlex drive’s internal DSI communication port, eliminating the requirement for an independent external power supply.
