By: Austin Scott, Austin Scott

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.

Building Sequential Function Charts

In this chapter, we will implement a Sequential Function Chart (SFC) routine and break down the steps, actions, transitions, and branches that are used to construct it. We will also work with the online editing capabilities of SFC routines. Just as we have seen with the other IEC languages, SFC shares many of the common elements of other languages, but allows us to structure our programs in a different way. SFC programs are very well suited to running batches and cycles that follow a sequential step process or decision tree.

In this chapter, we will cover the following topics:

  • Introducing SFCs
  • Applying SFCs
  • Using the SFC editor
  • Building a backwash SFC routine

We will start this chapter with an overview of SFCs and their typical use within an industrial control system solution.
