Allen-Bradley 20-COMM-E EtherNet/IP Communication Adapter – PowerFlex Drive Communication Module
When an industrial drive loses network connectivity on the plant floor, the consequences cascade instantly — production lines halt, PLCs throw faults, and maintenance teams scramble under pressure. The communication adapter is not a peripheral accessory; it is the critical bridge that keeps your PowerFlex drive synchronized with the control network. Without a reliable EtherNet/IP adapter, your entire drive-based automation system is effectively isolated, unable to receive commands, report diagnostics, or participate in coordinated motion sequences.
The Allen-Bradley 20-COMM-E occupies a well-established position within Rockwell Automation’s PowerFlex peripheral communication adapter family. Designed specifically for PowerFlex 70, 700, 700H, 700S, 700L, 7000, and 7000L AC drives, this module enables seamless EtherNet/IP integration — the most widely deployed industrial Ethernet protocol in North American and global manufacturing. As factories accelerate toward Industry 4.0 architectures, the 20-COMM-E remains a foundational component for connecting legacy and modern PowerFlex drives to Logix-based control systems.

Frequently Asked Questions
- Q: Is the 20-COMM-E compatible with PowerFlex 40 or PowerFlex 4 drives?
- A: No. The 20-COMM-E is designed for the PowerFlex 70/700 family. PowerFlex 40 uses the 22-COMM series adapters. Please verify your drive model before ordering.
- Q: Can I use the 20-COMM-E with a non-Rockwell EtherNet/IP scanner?
- A: Yes. EtherNet/IP is an open standard (ODVA). The 20-COMM-E can communicate with any compliant EtherNet/IP scanner, though Rockwell Logix controllers offer the deepest integration.
- Q: Do you provide the EDS file for the 20-COMM-E?
- A: Yes, we can provide the EDS file upon request, or direct you to the official Rockwell Automation PCDC download portal.
- Q: What is the lead time for this part?
- A: In-stock units typically ship within 1–3 business days. Lead time for sourced units is 5–10 business days depending on availability.
- Q: Do you offer a warranty?
- A: Yes, we offer a 90-day quality warranty on all shipped units. Contact us immediately if you receive a defective item.
