Overview of this book

Understanding programmable logic controller (PLC) programming with Rockwell Software’s Logix Designer and the Studio 5000 platform, which includes ControlLogix, CompactLogix, and SoftLogix, is key to building robust PLC solutions. RSLogix 5000/Studio 5000’s Logix Designer are user-friendly IEC 61131-3-compliant interfaces for programming the current generation of Rockwell Automation Controllers using Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), and Sequential Function Chart (SFC). This second edition of Learning RSLogix 5000 Programming guides you through the technicalities and comes packed with the latest features of Studio 5000, industrial networking fundamentals, and industrial cybersecurity best practices. You’ll go through the essential hardware and software components of Logix, before learning all about the new L8 processor model and the latest Studio 5000 architecture to build effective integrated solutions. Entirely new for this edition, you’ll discover a chapter on cybersecurity concepts with RSLogix 5000. The book even gets you hands-on with building a robot bartender control system from start to finish. By the end of this Logix 5000 book, you’ll have a clear understanding of the capabilities of the Logix platform and be able to confidently navigate Rockwell Automation Literature Library resources.

Introducing GuardLogix safety controllers

With the launch of the (Bulletin 1756) GuardLogix controller in 2005, the ControlLogix platform supported both standard and safety system control in the same chassis. The GuardLogix controller system is designed for use in safety applications, including SIL 3 (IEC 61508) and applications up to and including PLe/Cat.4 (ISO 13849-1).

The GuardLogix safety controller is part of a failsafe (de-energize to trip) system. This means that when a fault is detected, all of its outputs are set to 0. In the event of a faulty input or input module, the GuardLogix safety controller automatically sets any input values associated with them to 0. The Series 6 (L6), Series 7 (L7), and Series 8 (L8) controllers are all available in the GuardLogix form factor.

Physically, the GuardLogix controllers are usually installed in pairs—the primary controller and the safety partner controller. GuardLogix controllers closely resemble normal...
