The master's thesis describes the process of implementing a digital twin using the Siemens software package which includes the CAD environment NX, the connecting environment SIMIT, and the TIA portal environment for programming PLC. The aim of the work was to learn how to use the software package and understand its operation to introduce the digital twin technology into the machine manufacturing process. The first part describes the theoretical background of the technology with descriptions of each software environment. An example of a machine that was converted into a digital form and simulated its operation is described. The detailed process of describing the moving parts in the NX environment and using the connecting environment SIMIT for processing and connecting signals with the control program in the TIA portal environment is shown. Finally, the virtual start-up of the machine is demonstrated using user interface which allows manual and automatic control of the machine, as well as troubleshooting and detection of machine faults. The conclusions describe the findings and possible improvements for future projects.
