Virtual technologies are increasingly used in education and training. In this paper, a solution using virtualization technology in teaching Programmable-Logic-Controller (PLC) Experiment subject is presented. VMWare ESXi hypervisor is used to create Windows virtual machines as well as virtual machines for network routing and data storage. Hardware and virtual machines installation, network configuration, external hardware connection, and class organization are deployed. The effectiveness of virtual technology is confirmed in teaching the course of PLC Experiment.
