Objectives

  • Explain how PLCs, inputs, outputs and the PLC scan cycle work in industrial automation.
  • Read, create and simulate PLC ladder logic using contacts, coils, rungs, tags and free PLC tools.
  • Translate machine requirements into AND, OR, XOR and NOT logic using NO and NC contacts.
  • Build motor Start/Stop circuits using seal-in latches, Set/Reset instructions and one-shots.
  • Configure TON, TOF and RTO timers and CTU, CTD and CTUD counters for automation tasks.
  • Use comparison, range-check, math and MOVE instructions to process numerical PLC data.
  • Design traffic lights and machine sequences using finite state machines and state transitions.
  • Build and test an automatic bottle-filling station using timers, counters, states and outputs.
  • Use Claude AI to draft I/O lists, explain ladder logic and assist with PLC debugging responsibly.
  • Test PLC programs, identify common ladder logic errors and verify safe operation in simulation.


Pre Requisites

  1. No previous PLC programming, ladder logic or industrial automation experience is required.
  2. A computer with internet access and a modern web browser is required for the free PLC simulator
  3. No physical PLC, electrical equipment or paid industrial software is required.
  4. Basic computer skills and a willingness to complete the hands-on exercises are recommended.


FAQ

  • Q. How long do I have access to the course materials?
    • A. You can view and review the lecture materials indefinitely, like an on-demand channel.
  • Q. Can I take my courses with me wherever I go?
    • A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
