Tiivistelmä
This thesis was commissioned by HAMK University of Applied Sciences. The goal of the thesis was to create a PLC controlling program for a five-floor elevator system for future educational purposes at HAMK University of Applied Sciences.
The theory section discussed related background information such as the definition and classification of elevators and PLCs. In addition, a description of a PLC-based controlling system was added to explain the PLC’s role in a realistic application along with other components.
The documentation contains a description of the program and guides for building the project, which can be viewed as a teaching material in ladder logic and function block diagram programming. The program controls elevator operations such as car calls, floor calls, open, close buttons as well as safety sensors. An HMI screen was also added in the project for visualization and a better monitoring of the program.
The program was simulated and visualized successfully, therefore it is reliable to be used as a teaching material in future courses. In addition, in the author’s opinion, the program can potentially be adapted for testing operations as wells commercial applications in small apartment buildings.
