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
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
