  • Course details

    Sequence processes are common in manufacturing and used often in ladder logic, the popular language for programming major PLC devices. In this practical course, instructor Zahraa Khalil demonstrates how to use sequencer instructions in PLC ladder logic programming. To help lend each concept a real-world context, Zahraa shares practical examples involving everything from traffic lights to dishwashers. She shines a spotlight on three key sequencer instructions: sequencer output instruction (SQO), sequencer compare instruction (SQC), and sequencer load instruction (SQL). Along the way, she includes challenges that help you solidify your understanding of each concept.

    Skills covered in this course

  • Getting to know PLC sequencers

    - Have you ever wondered what a dishwasher, traffic lights, and food pack and processes have in common? All of these have a sequence of some kind. In manufacturing and industrial settings, PLC programming is often used to control machines that have a stepped sequence of repeatable operations. In this LinkedIn Learning course, I'll explain a couple of the Sequencer instructions used in PLC ladder logic programming like Sequencer output, compare, and load instructions. We will explore each instruction separately and go through examples with step-by-step solutions to better understand the concept. You will also see the examples in the simulation software. At the end of each chapter, I'll propose a challenge for you to work on. The last chapter is a challenge that includes all the instructions we worked on during this course. Hi, I'm Zharaa Khalil. I am an engineering instructor and I love teaching students just like you.…
