This thesis work investigates the possibilities and limitations of using digital twin technology to create virtual automation lines which can be used in education and research to conduct automation labs virtually. The PTC automation line at University West has been used as a case study in this thesis. The digital twin created in this work consists of three key parts: a virtual model of the automation line created in Visual Components Premium 4.2, system control (PLC-control program) created in TwinCat 3, and a Beckhoff ADS communication protocol that connects the virtual model with the PLC program.

Using a virtual model of industrial-like lab equipment in place of a real system can bring several benefits. It can increase visibility and safety in the system. It can also increase the accessibility of the system. Conducting virtual labs and experiments can also help in reducing the total cost of the system. The virtual twin of the automation line built in this work can be used to help the users to conduct automation labs and experiments virtually and to test their PLC programs offline.
