Allen-Bradley 5094-AENTR 2-Port EtherNet/IP Adapter Module

Configured for distributed I/O communication in EtherNet/IP networks, the Allen-Bradley 5094-AENTR (5094-AENTR 2-Port EtherNet/IP Adapter Module) provides direct physical and network-layer connectivity between FLEX 5000 I/O modules and Logix-based control systems. The adapter supports dual Ethernet ports, Device Level Ring (DLR), Parallel Redundancy Protocol (PRP), and high-speed backplane communication for deterministic industrial Ethernet environments.

Hardware Specifications

EtherNet/IP Deterministic Network Integration

The 5094-AENTR incorporates dual Ethernet interfaces and a 1 Gbps backplane communication channel for connectivity with FLEX 5000 distributed I/O assemblies. Support for Device Level Ring (DLR) and Parallel Redundancy Protocol (PRP) enables network architectures designed to minimize communication interruption during media or device faults.

The adapter supports automatic negotiation at 10 Mbps, 100 Mbps, and 1 Gbps network speeds while maintaining EtherNet/IP communications between field I/O modules and Logix controllers. IP addressing may be assigned through hardware rotary switches or network-based DHCP and BOOTP services.

Frequently Asked Questions

Q: How many FLEX 5000 I/O modules can be connected to one adapter?
A: A single 5094-AENTR adapter supports up to eight FLEX 5000 I/O modules.

Q: Does the adapter support hot replacement of I/O modules?
A: Yes. The module supports RIUP (Removal and Insertion Under Power) for I/O modules installed to the right of the adapter. This operation should not be performed in hazardous classified areas.

Q: What network redundancy methods are supported?
A: The adapter supports Device Level Ring (DLR) and Parallel Redundancy Protocol (PRP) network architectures, in addition to linear and star topologies.

Field Installation Guidelines

• Mount the adapter on a properly grounded DIN rail inside an industrial control enclosure.

• Install the adapter at the left-most position of the FLEX 5000 I/O assembly as specified by the system architecture.

• Fit the required end cap after the last I/O module in the assembly.

• Verify that the incoming supply voltage remains within the specified 18-32 VDC operating range.

• Route Ethernet cables separately from motor power and high-current conductors.

• Use industrial-rated Ethernet cabling and properly secure RJ45 connectors.

• Confirm DLR or PRP configuration settings before placing redundant network systems into operation.

• Validate Ethernet link status, adapter diagnostics, and controller communication after startup.

• Do not perform RIUP operations in hazardous locations classified as explosive atmospheres.
