This paper deals with the analysis and implementation of safety systems in industrial automation, with special emphasis on the application of safety PLCs and associated safety elements. The working principles of safety PLCs and their integration with light curtains, safety doors and other key components are explained through theoretical treatment. Furthermore, in the practical part of the work, a simulation of an industrial plant was created using software tools such as Factory IO and TIA Portal, where risks were analyzed and safety measures were implemented. The conducted tests have shown that the integration of safety PLCs and components significantly contributes to reducing risks and increasing safety in industrial processes. The simulations made it possible to visualize the functionality of the security systems and evaluate the effectiveness through different scenarios. The results indicate the importance of using advanced safety technologies in industrial plant design, providing valuable insights for further development and implementation in real systems. Work in this way represents a contribution to the development of safety solutions for modern industry and provides a basis for improving safety standards in industrial automation.
