Allen Bradley 20-750-ENETR PowerFlex 750-Series Dual-Port EtherNet/IP Option Module

Product Overview

The Allen Bradley 20-750-ENETR provides high-performance networking capabilities for PowerFlex 750-Series Variable Frequency Drives (VFDs). This dual-port EtherNet/IP option module facilitates seamless integration between the drive and Logix-based control systems. It enables real-time data exchange, drive configuration, and advanced diagnostics over a standard industrial Ethernet backbone. We supply this module as 100% Brand New original equipment, ensuring full firmware compatibility and high-speed synchronization for your motion control applications.

Technical Specifications

The 20-750-ENETR utilizes the DPI protocol to interface with the drive while providing high-speed Ethernet connectivity to the plant network.

Engineering Advantages

• DLR Topology Support: The dual-port design allows the implementation of a Device Level Ring (DLR) topology. This enhances network resiliency by providing a redundant communication path; the network continues to operate without interruption even if a single cable segment fails.

• Simplified Drive Commissioning: This module eliminates the need for complex serial adapters. Engineers configure the drive directly through Studio 5000 Logix Designer or Connected Components Workbench software via the Ethernet port, significantly reducing startup time.

• Advanced Internal Diagnostics: The module monitors drive status and internal parameters in real-time. It pushes critical fault data and energy consumption metrics directly to the HMI or controller, allowing for proactive maintenance and reduced unscheduled downtime.

• High-Speed Synchronization: The 10/100 Mbps data rate ensures low-latency command execution. The module handles high-bandwidth traffic effectively, preventing network bottlenecks during large-scale data transfers or high-axis count coordination.

FAQs

• Does the 20-750-ENETR require an external power supply?

  No. The module draws its required 250 mA operating current directly from the drive's internal DPI bus. This eliminates additional wiring and simplifies the physical installation within the drive's option slot.

• Can I use this module to connect two different drives together?

  The dual ports function as an embedded switch. You use the ports to "daisy-chain" multiple drives in a linear or ring topology, which reduces the number of ports required on your primary industrial Ethernet switch.

• How do I set the IP address for the module?

  You can set the IP address using the BOOTP/DHCP utility, through the drive’s Human Interface Module (HIM), or via software tools like Studio 5000. The module stores the address in non-volatile memory to ensure it persists after a power cycle.

• Is this module compatible with PowerFlex 753 drives?

  Yes. While the PowerFlex 755 features a built-in Ethernet port, the 20-750-ENETR serves as the primary Ethernet interface for the PowerFlex 753. In PowerFlex 755 applications, engineers often add this module to provide a second, isolated network path or to enable DLR functionality.
