In the thesis I am describing the adaptation of SCADA / HMI systems for support of the industrial process in the steel industry. I've created an interface that gives operators insight and the ability to manage individual machines or the entire process. For development, I used the Siemens product WinCC 7.3, which I also used for the presented project. I will describe in detail the most important WinCC tools needed for the successful use of this software. The interface itself is developed according to certain internal standards and requirements. For the designed interface, I analyzed the user`s experience. The analysis showed that the interface contained imperfections that I improved with help of user`s feedback and my best abilities. It is an improvement in navigation, material tracking and easier use of the interface itself.
