Course content

7 sections • 37 lectures • 7h 40m total length

  • Introduction to the Course1:57

    Master PLC basics with Codesys: what a PLC is and components. Explore the IEC 61 1313 standard, Codesys environment, and structured text language through practical exercises and graphical simulations.

  • What is a PLC?5:47
  • CPU and RTOS6:28

    Explore how the PRC CPU runs user code with a real-time OS, managing static priorities, cycle times, and task scheduling to prevent missed deadlines and ensure safe PLC operation.

  • Input and Outputs - Digital and Analog Signals6:35
  • Analog Signals Scaling2:25

    Learn to scale analog signals from range to another with a formula. See how 0–10 volts maps to 10–50 degrees Celsius and perform forward and inverse scaling.

Requirements

  • There are no mandatory requirements for this course. A basic knowledge of electronics and computer science may help you, but a technical mentality and a desire to learn is all you need for this course.
  • It is not necessary to have a physical PLC, or to have software already installed on your PC.
