🔧 Step-by-Step: Connect 1769-L24ER-QBFC1B to POINT I/O Using 1734-AENTR

📦 Required Hardware (All Available In Stock):

• ✅ 1769-L24ER-QBFC1B CompactLogix Controller

• ✅ 1734-AENTR EtherNet/IP Adapter

• ✅ 1734-IR2 Analog Input Module

• ✅ 1734-IR2E Enhanced Analog Input Module

• ✅ 1734-IT2I Thermocouple Input Module

• ✅ POINT I/O Terminal Base Units (e.g., 1734-TB, 1734-TOP)

🔌 Step 1: Power and Configure the CompactLogix Controller

1. Mount the 1769-L24ER-QBFC1B on a DIN rail.

2. Connect power (24VDC) to the controller.

3. Connect your PC via Ethernet to one of the controller’s ports.

4. Launch BOOTP/DHCP Server or use Studio 5000 to assign a static IP address to the controller.

5. Open Studio 5000 and create a new project selecting:

   • Controller: 1769-L24ER-QBFC1B

   • Firmware version: (match the controller’s version, e.g., v32)

🌐 Step 2: Configure the EtherNet/IP Network

1. Assign a static IP to the 1734-AENTR adapter using BOOTP or rotary switches.

2. Ensure both devices (L24ER and AENTR) are in the same subnet (e.g., 192.168.1.x).

3. Connect an Ethernet cable from Port 1 of the L24ER to Port 1 of the 1734-AENTR.

🧩 Step 3: Physically Assemble the POINT I/O Modules

1. Mount the 1734-AENTR on a DIN rail.

2. Attach the POINT I/O power supply module (e.g., 1734-EP24DC).

3. Snap in the base modules (e.g., 1734-TOP).

4. Plug in each module in this order:

   • 1734-IR2

   • 1734-IR2E

   • 1734-IT2I

⚠️ Tip: Always match each module with its corresponding terminal base (e.g., IR2 with 1734-TOP).

🖥️ Step 4: Add the 1734-AENTR to the Studio 5000 I/O Tree

1. In your Studio 5000 project, expand I/O Configuration.

2. Right-click EtherNet/IP → New Module.

3. Search and select:

   • 1734-AENTR (select the correct revision)

4. Enter:

   • Name: POINTIO_Adapter (or your custom name)

   • IP Address: Same as you configured

   • Chassis Size: Number of modules connected (e.g., 3 for IR2, IR2E, IT2I)

   • Slot: Always 0 for the AENTR adapter

📥 Step 5: Add Child Modules (IR2, IR2E, IT2I)

1. Right-click the AENTR module → New Module.

2. Add:

   • 1734-IR2 → Slot 1

   • 1734-IR2E → Slot 2

   • 1734-IT2I → Slot 3

3. For each module:

   • Select correct catalog number and revision

   • Match the wiring type: voltage or thermocouple

   • Define Input Data Format (e.g., Engineering Units or Raw)

🟢 Step 6: Final Checks and Download

1. Save and compile the project.

2. Connect all devices and power on.

3. Download the project to the CompactLogix controller.

4. Monitor module status lights:

   • Solid green = good communication

   • Flashing = missing configuration

5. Use Controller Tags to verify I/O data.

❓ FAQ: Common Questions

Q1: Can I add more modules to the 1734-AENTR later?

Yes, you can expand up to 63 POINT I/O modules per adapter, depending on power and bandwidth limits.

Q2: Do I need EDS files to add these modules in Studio 5000?

Most recent versions include the EDS files. If not, you can download them from Rockwell’s Product Compatibility Download Center (PCDC).

Q3: What happens if the AENTR loses power?

All I/O data is lost until power is restored, and communication resumes. The controller will show a communication fault if not handled in the logic.

Q4: Can I daisy-chain another adapter using the second port?

Yes, the second port on 1734-AENTR supports linear topologies and DLR (Device Level Ring) for redundancy.
