1. Adapter Overview

The 5069-AENTR is the EtherNet/IP adapter for the Compact 5000 I/O platform. It acts as the bridge between a remote bank of Compact 5000 I/O modules and a Logix 5000 controller elsewhere on the EtherNet/IP network. The adapter handles all network communication, provides power distribution to the I/O modules, and supports as many as 31 Compact 5000 I/O modules in a single bank.

When to Use a Remote I/O Adapter

A CompactLogix 5380 controller (such as the 5069-L306ER) has local I/O slots built in — you install I/O modules directly to the right of the controller. But what if your I/O is physically distant from the controller? That is where the 5069-AENTR comes in:

1. Remote I/O panels. The controller is in a main electrical room, but sensors and actuators are in a satellite panel 50 meters away. Install an AENTR in the remote panel with the I/O modules, connected back to the controller over Ethernet.
2. Distributed architectures. Multiple I/O banks spread across a facility, each with its own AENTR, all communicating with a single controller over EtherNet/IP.
3. Expanding beyond local I/O capacity. If you need more I/O points than the controller's local bus can support, add remote I/O banks via AENTR adapters.

Compatible Controllers

The following Logix 5000 controllers can own the 5069-AENTR as a remote I/O adapter:

2. 5069-AENTR vs. 5069-AEN2TR Comparison

Allen-Bradley offers two EtherNet/IP adapter options for the Compact 5000 platform. The 5069-AENTR is the standard single-adapter module, while the 5069-AEN2TR is a newer dual-port adapter. Both serve the same fundamental purpose — bridging remote I/O to EtherNet/IP — but differ in size, power characteristics, and terminal block compatibility.

5. System Planning

Before installing the 5069-AENTR, plan the remote I/O bank layout, power budget, and network topology. This section covers the key planning considerations.

Adapter Placement

The 5069-AENTR must be the first (leftmost) component in the remote I/O bank. I/O modules install to the right of the adapter, connecting via the high-speed internal bus. An end cap must be installed on the rightmost module to cover the exposed bus connectors and prevent electrical shock.

I/O Module Capacity

A single 5069-AENTR supports up to 31 Compact 5000 I/O modules. This is more than sufficient for most remote I/O panels. If you need more than 31 modules at one location, add a second AENTR and create a second I/O bank.

Power Budget

The AENTR passes MOD and SA power through to the I/O modules via the internal bus. You must ensure the total current draw of all I/O modules does not exceed 10 A on either the MOD or SA power bus. Key power values for the AENTR itself:

Network Topology

The 5069-AENTR has two Ethernet ports with an embedded switch, supporting three network topologies:

1. Star topology. Each adapter connects to an Ethernet switch via a single cable. Simple, uses standard switch infrastructure. Use one or both ports (second port unused in pure star).
2. Linear (daisy-chain) topology. Adapters are daisy-chained from one to the next using both ports. Simple cabling but no redundancy — a cable break isolates downstream devices.
3. DLR (Device Level Ring) topology. Adapters are daisy-chained in a ring that closes back to a DLR-capable switch or controller. Provides network redundancy — if a cable breaks, traffic reroutes through the alternate path. Recovery time is typically under 3 ms.

6. Hardware Installation

DIN Rail Requirements

The adapter mounts on standard 35 mm DIN rail:

Installation Steps

1. Power off all sources. Disconnect MOD power, SA power, and Ethernet cables before beginning installation.
2. Mount the DIN rail. Secure the 35 mm DIN rail in the panel with appropriate mounting hardware. Ensure minimum 25 mm (1 in.) clearance on all sides for airflow. Ground the rail every 200 mm.
3. Install the AENTR adapter. The adapter must be the leftmost component in the bank. Hook the top rail clip over the DIN rail, then press the bottom of the adapter until the lower clip locks with an audible click.
4. Install I/O modules to the right. Snap each I/O module onto the DIN rail and slide it against the adjacent module (adapter or previous module) until the internal bus connector engages. Ensure no visible gap between modules.
5. Install the end cap. After the rightmost I/O module, install the end cap to cover the exposed bus connectors. This prevents electrical shock and protects the bus contacts from contamination.
6. Install RTBs. Snap the 5069-RTB5-SPRING or 5069-RTB5-SCREW terminal block onto the adapter. Install the appropriate RTBs on each I/O module.

7. Power Wiring

The 5069-AENTR uses a 5-pin removable terminal block (5069-RTB5-SPRING or 5069-RTB5-SCREW) for both MOD and SA power connections. This is not the same RTB64 kit used by CompactLogix controllers — the AENTR uses the smaller RTB5.

RTB5 Pin Assignments

Note: The pin labels and assignments shown above correspond to the MOD and SA power connections on the RTB5. Refer to the markings on the adapter housing for exact pin identification on your unit.

MOD Power Wiring

MOD (module) power supplies system power to the adapter and passes it through to all I/O modules via the internal bus. MOD power operates at 18–32V DC.

1. Connect 24V DC+ to the MOD (+) terminal.
2. Connect 24V DC− to the MOD (−) terminal.
3. Strip insulation to 10 mm (0.39 in.) for both spring and screw RTBs.
4. For screw terminals: torque to 0.5...0.6 N·m (4.4...5.3 lb·in).

SA Power Wiring (DC)

SA (sensor/actuator) power supplies field-side power to I/O modules. For DC applications (0–32V DC):

1. Connect DC+ to the SA (+/L) terminal.
2. Connect DC− to the SA (−/N) terminal.
3. Connect earth ground to the SA ground terminal.

SA Power Wiring (AC)

For AC applications (0–240V AC, 47–63 Hz):

1. Connect L1/AC+ to the SA (+/L) terminal.
2. Connect L2/N/AC− to the SA (−/N) terminal.
3. Connect earth ground to the SA ground terminal.

Wire Specifications

8. Network Setup

The 5069-AENTR has two RJ45 Ethernet ports on the bottom of the adapter with an embedded switch supporting 10/100/1000 Mbps. You can set the IP address using rotary switches on the side of the adapter, or use DHCP/BOOTP.

IP Address via Rotary Switches

Three rotary switches on the side of the adapter set the last octet of the IP address. The adapter ships with the switches set to 999 (DHCP enabled).

1. Power off the adapter. Do not change switch settings while power is on.
2. Set the three rotary switches to your desired last octet (e.g., 010 for 192.168.1.10).
3. Power on the adapter. The adapter will use IP address 192.168.1.xxx with a subnet mask of 255.255.255.0.

Ethernet Cabling

Connect RJ45 straight Ethernet cables to the ports on the bottom of the adapter. Rockwell 1585J cables are recommended:

Ethernet Pin Assignments (RJ45)

Note: For 10/100 Mbps operation, only pins 1, 2, 3, and 6 carry data. Pins 4, 5, 7, and 8 are used for Gigabit (1000 Mbps) operation. Use 8-pin cables if you require Gigabit speeds.

9. Studio 5000 Configuration

The 5069-AENTR is configured in Studio 5000 Logix Designer. You add the adapter to the controller's I/O tree as a remote EtherNet/IP device, then add I/O modules underneath it — exactly the same modules and configuration dialogs as local I/O.

Adding the Adapter to the I/O Tree

1. Open your Studio 5000 project. In the Controller Organizer (left panel), expand I/O Configuration → Ethernet.
2. Right-click the Ethernet node and select New Module.
3. Search for “5069-AENTR” in the module catalog. Select it and click Create.
4. Set the Name — use a descriptive name such as RemoteIO_Panel1 or AENTR_Building2.
5. Set the IP address to match the rotary switch setting (e.g., 192.168.1.10).
6. Set RPI (Requested Packet Interval) — default is 10 ms. Adjust based on your application requirements. Lower RPI = faster updates but higher network load.
7. Set the connection type. Use Rack Optimization to combine multiple I/O module connections into fewer network packets for better performance.
8. Click OK. The adapter appears in the I/O tree under the Ethernet node.

Adding Remote I/O Modules

1. Right-click the AENTR adapter in the I/O tree and select New Module.
2. Search for the I/O module catalog number (e.g., 5069-IB16, 5069-OB16, 5069-IF8).
3. Set the Name and Slot number. The slot number corresponds to the physical position: Slot 1 = first I/O module to the right of the adapter, Slot 2 = second module, and so on.
4. Configure module-specific settings (input filters, output fault modes, channel configuration) the same way as local I/O modules.
5. Repeat for each I/O module in the remote bank.

Electronic Keying

The 5069-AENTR supports electronic keying, which verifies that the physical module matches the configured module in the I/O tree. Keying options:
