Engineering Advantages
-
Native Modbus/TCP Integration: The 20-COMM-M enables PowerFlex drives to communicate directly with non-Rockwell PLCs and SCADA systems that utilize the Modbus/TCP protocol. This eliminates the need for expensive third-party gateways.
-
Internal Mounting Space Efficiency: The adapter mounts directly inside the drive’s communication slot. This internal placement saves valuable DIN rail space and protects the module from external environmental contaminants.
-
Real-Time Diagnostics: The module facilitates the high-speed transfer of drive parameters, including output frequency, current, and fault codes. Operators gain real-time visibility into motor performance, allowing for proactive maintenance before mechanical failures occur.
-
Simplified Configuration: The 20-COMM-M supports standard Ethernet cabling (RJ45), which simplifies the physical layer of the network. Engineers configure the adapter through drive tools or standard web browsers, reducing commissioning time.
-
Robust Data Isolation: The hardware design ensures electrical isolation between the drive’s internal power circuits and the Ethernet network, preventing electrical noise from interfering with plant-wide communications.
FAQs
-
Which PowerFlex drives support the 20-COMM-M?
The 20-COMM-M primarily supports Allen Bradley PowerFlex 7-Class drives, such as the PowerFlex 70, PowerFlex 700, and PowerFlex 700S. Always verify your drive's firmware version to ensure full feature compatibility.
-
Does this unit require an external power supply?
No. The 20-COMM-M draws its operating power directly from the drive's internal DPI port. This simplifies wiring and reduces the risk of power-related communication drops.
-
Is this a genuine Allen Bradley original product?
Absolutely. We ship only 100% brand new, factory-original Allen Bradley 20-COMM-M adapters. Each unit arrives in its original manufacturer packaging to meet strict E-E-A-T industrial procurement standards.
-
What is the primary function of the DPI interface on this module?
The DPI (Drive Peripheral Interface) acts as the high-speed serial link between the drive’s internal microprocessor and the 20-COMM-M. It ensures that control commands and status updates move between the network and the drive with minimal jitter.

Tech & Buying Guide
Strategic Selection: Choosing the Right SCADA Software for Your PLC Project
In industrial automation, the SCADA (Supervisory Control and Data Acquisition) system acts as the bridge between raw machine data and actionable human intelligence. Selecting the incorrect software platform can lead to integration bottlenecks, scalability issues, and excessive long-term maintenance costs. As an automation consultant with 15 years of experience, I have guided many projects through the selection process. Below are the essential criteria for choosing a platform that ensures both performance and longevity.
Ensuring Operational Continuity: The Strategic Value of Redundant Automation Systems
In modern industrial landscapes, unplanned downtime is the ultimate adversary. For sectors relying on complex PLC and DCS architectures, a single hardware failure can trigger catastrophic production losses. Therefore, implementing redundant automation systems is no longer a luxury; it is a fundamental requirement for mission-critical operations. In this article, I analyze why redundancy remains the backbone of reliable industrial infrastructure.
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
