Learning RSLogix 5000 Programming

Overview of this book

RSLogix 5000 and Studio 5000's Logix Designer are user-friendly interfaces used for programming the current generation of Rockwell Automation Controllers including ControlLogix, CompactLogix, and SoftLogix. When engineering automation solutions using Logix, it is important to study the changes to the platform introduced with Studio 5000 and the various controllers, modules, and form factors available today. RSLogix 5000 programming packages help you maximize performance, save project development time, and improve productivity. This book provides a detailed overview of the Logix platform including ControlLogix, CompactLogix, and SoftLogix and explains the significant changes introduced in Studio 5000. A clear understanding of the recent Logix platform changes is critical for anyone developing a Rockwell Automation solution. It provides an easy-to-follow, step-by-step approach to learning the essential Logix hardware and software components and provides beginners with a solid foundation in the Logix platform features and terminology. By the end of this book, you will have a clear understanding of the capabilities of the Logix platform and the ability to navigate the Rockwell Automation Literature Library Resources.

Network communication technologies


Communications play a vital role in most industrial automation solutions, and Rockwell Automation's Integrated Architecture offers a variety of options. I have classified these options as primary network technologies (those that are actively used in modern implementations of a Logix system) and legacy network technologies (those that have been used frequently in the past but are not being installed in the new Logix control systems).

Primary network technologies

Today, Logix relies on the following three primary technologies for network communication:

  • DeviceNet

  • ControlNet

  • EtherNet/IP

Let's discuss each of them in detail.

DeviceNet

DeviceNet is designed specifically to communicate with and provide power to the lowest-level field devices. It can communicate with intelligent devices that support a DeviceNet module such as sensors, VFDs, valves, motors, and distributed I/O blocks. DeviceNet is convenient as it provides both signal and power to the device. However,...
