Beckhoff TwinCat3 PLC Programming Basics

About Beckhoff TwinCat3 PLC Programming Basics

This comprehensive course is designed to teach you the

fundamentals of Beckhoff PLC programming using TwinCAT 3

, starting from scratch. Whether you're a student, technician, or automation enthusiast, you'll gain a solid foundation in relay logic, ladder diagram programming, and real-time simulation—all without needing any physical hardware. You'll learn to set up the TwinCAT 3 software environment, develop ladder logic programs, and test them using the built-in simulator. The course is structured to provide

hands-on experience through step-by-step video lectures and practical assignments

that mirror real-world industrial scenarios. No prior experience is required, and everything you need to practice is included in the course materials. Simply install TwinCAT 3 on your PC and start learning!
