25-COMM-E2P — EtherNet/IP Dual-Port Adapter Module

The 25-COMM-E2P is a plug-in EtherNet/IP communication adapter built for use with PowerFlex 525 series AC drives. It adds dual RJ-45 ports to the drive, supporting both linear and Device Level Ring (DLR) network topologies without needing an external switch. That alone makes it a practical choice for machine builders trying to reduce panel wiring and simplify network layouts.

Installation is straightforward — the module mounts directly onto the drive's option port, and parameter configuration can be handled through the drive's HIM or via network tools like Studio 5000 or FactoryTalk. Once online, it exposes full drive control and parameter access over EtherNet/IP, making it easy to integrate into existing control architectures.

Application Scenarios

Conveyor and Material Handling Lines In multi-drive conveyor systems, the dual-port DLR capability allows drives to be daisy-chained directly on the ring network. If one segment fails, traffic automatically reroutes — keeping the line running without intervention.

Packaging Machinery Packaging OEMs frequently integrate the 25-COMM-E2P into servo-driven filling and sealing stations where tight synchronization and real-time diagnostics are needed over the same EtherNet/IP backbone as the PLC.

HVAC and Building Automation Fan and pump drives in commercial building systems benefit from EtherNet/IP connectivity for BMS integration, remote parameter monitoring, and scheduled speed adjustments without on-site access.

Water and Wastewater Pump stations running PowerFlex 525 drives use this adapter to connect into SCADA systems, enabling flow data logging, fault diagnostics, and remote start/stop without additional communication hardware.

FAQ

Q: Can the 25-COMM-E2P be used with PowerFlex 523 drives?

The 25-COMM-E2P is designed specifically for the PowerFlex 525 platform. The PowerFlex 523 uses a different option port architecture and is not compatible with this adapter. For PowerFlex 523 communication options, a different module is required.

Q: Does DLR require any special switch or media converter?

No. DLR on the 25-COMM-E2P operates natively between the two onboard RJ-45 ports. Standard Ethernet cable is sufficient. A DLR-capable supervisor (typically provided by the PLC or managed switch) is needed to manage the ring topology, but no special hardware is required at the drive level.

Q: How is the IP address configured?

By default, the module ships with BOOTP enabled. You can switch to DHCP or assign a static IP through the drive's built-in HIM or via the network after initial connection. Static assignment is recommended for production environments to avoid address conflicts after power cycles.

Q: What happens to network communication if the drive faults?

The module remains powered and accessible on the network even if the drive is in a fault state. This allows diagnostics and fault code readback to continue uninterrupted — useful for remote monitoring systems that need to log fault data before a reset is issued.

Q: Can multiple 25-COMM-E2P modules be used in the same DLR ring?

Yes. DLR supports multiple nodes on the same ring, and each 25-COMM-E2P-equipped drive participates as a ring node. The ring supervisor (often a PLC module or managed switch) handles fault detection and traffic rerouting across all nodes in the ring.
