In the thesis, a system for a continuous process control based on a programmable logical controller (PLK) Siemens S7-1200 in TIA Portal environment is presented. The developed controller was to control a ball and hoop device. The work was done in the faculty’s laboratory.
First part of the thesis is focused on the theory behind the control systems. We have divided the systems by the principles on which they function. We have described two main types of system control, followed by a description of a PID controller, its parts, functioning and parameter settings.
The second part of the thesis describes programmable logical controllers and their functionalities, hardware that was used in the development of the system and the process of programming in TIA Portal environment.
The third part explains the practical part of the thesis performed in the laboratory. It presents a study model that has been used, development of the program, programming of the controller in the TIA Portal and development of the human-machine interface.
