Abstract

The thesis deals with design and implementation of web interface for visualization and control of a pneumatic system using a Siemens SIMATIC S7-1500 that works in web server mode. The thesis contains a brief description of PLC hardware and software tools, as well as a description of the pneumatic system. Attention is paid to the web interface and the options it offers. Specifically, to a data exchange between web interface and PLC, updating and visualizing data using Javascript and its libraries, the use of a web interface for data processing and security against unauthorized access. In addition to process monitoring, it also offers features for pneumatic cylinder control and for PID controller parameter design.
