Programming and Commissioning of a Mobile Electrical Cabinet for Testing Electrical Drives

Abstract

The aim of this thesis is to develop a mobile testing cabinet designed for the specific needs of the commissioning company. The main goal was to create a system that is as user-friendly as possible, allowing employees with no prior experience in PLC programming to operate it with ease. In addition, the system needed to be scalable and follow the company’s internal engineering standards to ensure consistency with existing equipment and future projects. The thesis describes the entire process of developing the cabinet, from selecting individual components to assembling the hardware and wiring the system. It also covers the programming of both the main control logic and the safety logic, as well as the design and implementation of the user interface. Along the way, several challenges typical of product development were encountered, such as hardware compatibility, layout constraints, and ensuring safety compliance. These issues were addressed through testing, troubleshooting, and close collaboration with company engineers. As a result, a first version of the mobile testing cabinet was successfully completed and delivered. This version meets the company’s current requirements and provides a solid foundation for further improvements. The company can continue to modify and expand the system to better support future applications or testing scenarios that were not identified during the initial development phase.
