The thesis presents the upgrade of an existing water level control system with the implementation of a SCADA interface, WinCC Runtime Advanced, in the TIA Portal environment. The original PID control program in the S7-1500 PLC remained unchanged, while the upgrade enabled improved process monitoring, data archiving, trend visualization, and enhanced user experience. The methodology includes an overview of the theoretical foundations of automation, control systems, and SCADA technology, followed by the practical implementation of the SCADA interface in a laboratory model. The results show that WinCC Runtime Advanced is fully sufficient for single-line systems with local access, whereas for larger industrial applications with multiple lines, multiple operators, and remote access, the use of WinCC Professional would be a more suitable choice. The conclusions confirm that such an upgrade improves process transparency and control without altering the basic control logic and provides a solid foundation for expansion into more complex environments.
