1769-L36ERM CompactLogix Controller | Allen-Bradley

Allen-Bradley 1769-L36ERM CompactLogix Controller

Product Introduction

The 1769-L36ERM belongs to the Allen-Bradley CompactLogix 5370 L3 series. This controller delivers powerful programmable automation for mid-range applications. It combines logic, motion, and communication in one compact unit.

Key Technical Specifications

The 1769-L36ERM includes 3MB of embedded memory for user programs and data. It also supports non-volatile storage via a 1784-SD1 (1GB) or 1784-SD2 (2GB) SD card.

For communication, this model features two EtherNet/IP ports and one USB port. The dual Ethernet ports support Device Level Ring (DLR), star, and linear topologies. Additionally, the 1769-L36ERM handles 16 axes of integrated motion over EtherNet/IP.

The controller works with up to 30 Compact 1769 I/O modules. You can arrange these into three expansion banks for flexible layout. Furthermore, it supports distributed I/O like 1734 POINT I/O and 1794 FLEX I/O.

Programming options include Relay Ladder, Structured Text, Function Block, and Sequential Function Chart (SFC). These follow the IEC 61131-3 standard. The controller also runs up to 32 continuous tasks and 100 programmable tasks.

Mechanical and Environmental Ratings

• Operating Temperature: 0 to 60 °C (32 to 140 °F)

• Relative Humidity: 5 to 95% non-condensing

• Vibration (Operating): 10 to 500 Hz, 5G, 0.030 in peak-to-peak

• Shock (Operating): 20G

• Wire Size (Solid): 22 to 14 AWG

• Wire Size (Stranded): 22 to 16 AWG

• Mounting: DIN rail or panel mounting

Installation Guidelines

First, observe the power supply distance rating of 4. This means the 1769-L36ERM must be placed no more than four modules away from the power supply. Use copper wire rated for 90°C.

Next, assign the IP address using BOOTP-DHCP, RSNetWorx, or the USB port for initial setup. For firmware V21 or later, use Studio 5000 Logix Designer.

You can mount the controller on DIN rail or directly on a panel. Ensure proper grounding and ventilation. Moreover, leave enough space for heat dissipation and cable access.

Compatible Systems and Devices

The 1769-L36ERM communicates seamlessly with other Allen-Bradley products. These include 1756 ControlLogix, 1734 POINT I/O, and Kinetix 5500 drives. It also supports messaging with PLC-5, SLC 500, and MicroLogix series. Therefore, you can integrate it into existing systems without major redesign.

For motion control, pair the 1769-L36ERM with Kinetix 350, Kinetix 5700, or PowerFlex 755 drives. This setup supports position, velocity, and torque loops effectively.

Frequently Asked Questions (FAQ)

1. Can the 1769-L36ERM replace an older 1769-L32E?
Yes, but you must verify firmware compatibility and update your program in Studio 5000. The 1769-L36ERM offers more memory and motion capabilities.

2. Does this controller support Ethernet/IP safety I/O?
No, the 1769-L36ERM does not support CIP Safety. For safety applications, consider 1769-L36ERMS or GuardLogix controllers.

3. How many axes can it control with integrated motion?
The 1769-L36ERM supports up to 16 axes of integrated motion over EtherNet/IP. This includes drives like Kinetix 5500 and PowerFlex 755.

4. What is the maximum program memory available?
It has 3MB of total memory. However, the user program size depends on structured data and tag usage. Use the SD card for additional storage.

5. Can I use this controller with third-party Ethernet/IP devices?
Yes, the 1769-L36ERM works with standard EtherNet/IP devices from other brands. Always test compatibility before deployment.
