Programmable Logic Controllers (PLCs) are crucial in industrial automation, making proficiency in their use an es- sential skill for engineering students. Choosing the right platform for teaching PLC programming in universities, however, may be challenging. This paper summarizes, compares and evaluates various software platforms used in universities. The leading platforms could be identified based on a defined criteria frame- work encompassing cost, accessibility, learning curve, industry relevance, supported languages, and additional features. Through detailed examination and discussion, the platforms that offer the most efficient and effective learning experience for PLC program- ming education in universities could be identified. This selection should further be justified by considering additional factors like instructor experience, student preferences, institutional support, and geographical location. This paper not only highlights the strengths and weaknesses of different platforms but also provides valuable insights and recommendations for universities seeking to optimize their PLC programming curriculum. The findings hold the potential to enhance the quality of PLC programming education, better preparing students for successful careers in automation-driven industries.
