The thesis describes in detail the process of modernising an automated warehousing system. It represents a partial modernisation, where the existing system is upgraded with new control devices and user interfaces.
The aim of the thesis is to demonstrate my own contribution to the software development and the adjustments after commissioning.
The thesis describes the theoretical background, the process of developing the solution, the testing and adaptation after commissioning and the reboot of the warehousing system.
The theoretical basis consists mainly of manuals and technical descriptions of the equipment manufacturer, literature in the field of automation in the STEP7 environment (TIA Portal). In addition, wiring diagrams and interface manuals were used.
The update is presented with explanations on the development of the new software environment, the troubleshooting of errors occurring during the transfer to the new environment and the extension of the software for the new interfaces.
The application of the theoretical background has led to a new solution that covers all the functionalities of the previous system. The focus of the work was on the development of new user interfaces.
The new user interfaces offer a faster handling of the system because the screen displays in the new solution are quickly accessible and clear. With fewer displays, the same functionality is achieved, with the user being able to distinguish functions, buttons and displays more easily and quickly.
The development process was carried out first in a simulation environment, then on the equipment in the warehouse at start-up. At each stage, testing is essential to show errors and the need for adjustments. Before commissioning, we are limited by the feedback we get from the system, which we only get during commissioning. The identified adjustment requirements have been implemented and fully tested in the system reboot.
The thesis highlights the lessons learnt, gives examples of solutions to the software code and user interfaces for a good and reliable end-product.
Finally, conclusions and recommendations for the modernisation of the automated warehouse system and interfaces are summarised.
