The CompactLogix Controllers

Learn Logix Part 2.6. This article gives an overview of the 1769 and 5069 CompactLogix controllers, their features, and the differences between the two series of controllers.

Learn Logix is a series of articles designed to teach you everything you need to know to work with Rockwell Automation’s Studio 5000 Logix Designer and the Logix 5000 series of PLCs.

In the last part of the series, we learned about the CompactLogix system and the main components in the system. You can find that part here or if you’re new to the series, you can find all of the previous parts here.

In this part of the series, we’ll look at the CompactLogix controllers and their features.

The main components of the 5069 and 1769 CompactLogix controllers are similar to each other and to the ControlLogix controllers. Specifically, both series of CompactLogix controllers have;

Secure Digital (SD) Card

A Secure Digital (SD) card provides non-volatile memory for storing the controller’s project.

Embedded USB Port

Both series of controllers have an embedded USB port. This USB port is used to create a temporary point-to-point connection between a controller and a programming device.

Energy Storage Module (ESM)

The embedded Energy Storage Module, also known as an ESM, provides power for the controller to retrieve its project from non-volatile memory after a power cycle or power loss.

Controller Mode Switch

A controller mode switch is used to select the operating mode of the controller.

Embedded Ethernet Switch

Both series of controllers have a 10 or 100 MB Ethernet switch built-in. This embedded switch supports a single IP address and a Device Level Ring network topology.

The 5069 CompactLogix Controller

The 5069 CompactLogix Controller

The 5069 CompactLogix controller is an enhanced version of the 1769 CompactLogix controller. This controller includes all of the features found in the 1769 CompactLogix controllers and is expanded to include;

Scrolling Display

A scrolling four-digit display provides additional information at a glance allowing for easier diagnostics and troubleshooting of the system.

Processor and Field Power Connections

New processor and field power connections allow you to use any power supply that meets the system requirements with a CompactLogix system.

Dual Configurable Ethernet Ports

In the 5069 CompactLogix, the enhanced dual Ethernet ports support speeds of up to 1,000 MB and two unique IP addresses.

Increased Memory

The 5069 CompactLogix controllers have up to 20% more memory than 1769 CompactLogix controllers.

Increased Security

The 5069 CompactLogix controllers have improved security features. Specifically, the controllers include;

  • Controller-based change detection and logging
  • Digitally signed controller firmware
  • Role-based access control (RBAC)

Conclusion

In this article, we learned about the CompactLogix controllers, their features, and the difference between the 1769 and 5069 series of CompactLogix controllers.

In the next part of the series, we will learn about the I/O modules that are available for the CompactLogix system. If you haven’t already, be sure to subscribe to the mailing list below to be notified when the next part is available.
