On 3 July 2024, the Faculty of Computer Science and Technology organised a workshop titled “Introduction to PLC Programming using Ladder Diagram.” The workshop was attended by six students from the Bachelor of Electronic Engineering, Bachelor of Mechanical Engineering, and Diploma in Mechatronics programs, one alumnus from the 2023 Diploma in Electronic Engineering program, and six academic staff members, totalling 13 participants.

The workshop began with an overview of the importance of PLCs in industrial applications. The primary purpose of a PLC is to control system behaviour using programmable logic. Following this introduction, an industrial application of PLCs was demonstrated through a student project designed to reject food containing metal contaminants.

Next, the theoretical aspects of programmable logic controllers were introduced, providing participants with a solid foundation in PLC programming. The attendees then engaged in simulation exercises using the TLP LogixPro Simulator, allowing them to apply their newfound knowledge in a controlled, virtual environment. The workshop concluded with a demonstration of a PLC application to control a garage door, highlighting the concept of interlocking programming.

Foo Cheong Jun, a third-year Bachelor of Electronic Engineering with Honours student, noted “The PLC training workshop was incredibly informative and practical. Learning how PLCs work and applying that knowledge through simulations like box filling with fill sensors was invaluable. The instructor is knowledgeable. This training has greatly enhanced my understanding of automation and will be instrumental in future projects.”

The workshop provided participants with a comprehensive understanding of PLC programming and practical knowledge that they can apply in their future careers in the industry.
