Learn Logix Part 2.0. This article gives an overview of the systems that make up the Logix 5000 platform and the use cases for each system.
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 what components make up a control system and how information flows through a control system. You can find that part here or if you’re new to the series, you can find all of the previous parts here.
Rockwell Automation’s Logix 5000 platform is made up of four distinct systems. Each of these systems is designed to provide the user with enhanced diagnostic and troubleshooting information, and increased security in comparison to other Rockwell Automation platforms like the Micro and MicroLogix platforms.
Each system in the Logix 5000 platform supports common industrial networks, like Ethernet/IP, and has a range of components that can be used to add functionality to a controller like I/O modules and communication modules.
In this article, we will learn about the various systems that make up the Logix 5000 platform and the difference between these systems.
The ControlLogix system is a high-performance multi-controller system in a modular chassis format.
In a ControlLogix system, multiple controllers located in the same chassis can operate independently and communicate with each other over the backplane.
This system is used in large systems with a large number of I/O points or systems that require high performance, such as systems with many motion axes.
The CompactLogix system is a modular, single-controller system.
The CompactLogix system is used in small, standalone projects or medium-sized connected systems.
The SoftLogix system is a software controller that is capable of combining control, information, and visualization using a Microsoft operating system running on a PC. The SoftLogix system is (as the name implies) a software PLC.
The GuardLogix system is a fully functioning Logix 5000 controller that provides SIL-3 safety control when applied properly.
All Logix 5000 systems use the same control engine and are programmed using the same development environment.
Up until firmware version 20, the development environment used was RS Logix 5000. From firmware version 21 on, the development environment used is Studio 5000 Logix Designer.
In this article, we learned what systems make up the Logix 5000 platform and the use cases for each system.
In the next part of the series, we will take a deep dive into the ControlLogix system to learn more about the hardware components that make up this system. Subscribe to the mailing list below to be notified when that part of the series is available.
Update: You can find the next part of the Learn Logix series, The ControlLogix System, here. This article gives an overview of the ControlLogix system and introduces the components that make up the ControlLogix system such as the ControlLogix chassis, power supply, and controllers.
Learn Logix Part 4.5. In this article, we learn about the various operating modes available for Logix 5000 controllers and the programming operations available in each mode.
Learn Logix Part 4.4. In this article, we learn how to understand and fix abnormal device states in RSLinx Classic.
