Master Thesis: Phase 2 – Advanced HMI Development and System Integration for Industrial X ray I[...]

XRAY-LAB GmbH & Co. KG develops industrial X-ray and CT inspection systems used for non destructive testing (NDT). As part of an ongoing software platform development, the Human-Machine Interface (HMI) for the X-ray inspection machine is being implemented in multiple phases.

directly on that foundation and focuses on advanced HMI features, imaging tools, calibration workflows, maintenance functions, and extended PLC communication.

The objective of this thesis is to extend and enhance the existing HMI with advanced functionality, focusing on usability, imaging quality, calibration, maintenance, and scalable communication.

Responsibilities

• Extend the existing HMI framework for industrial X-ray inspection systems with advanced imaging tools (filters, histogram analysis, line profile evaluation).
• Design and implement multi-mode calibration workflows with interactive visualization of calibration results.
• Enhance the HMI with extended maintenance and service functions, including diagnostic views, system monitoring, and structured event logging.
• Align manipulator hardware concepts with HMI control and visualization, ensuring intuitive operator interaction (X, Y, Z axes; tilt/rotation support optional).
• Expand PLC communication using OPC UA and optionally other communication protocols to support multiple industrial PLC vendors.
• Implement modular, maintainable software architecture for the HMI with focus on usability, scalability, and documentation.
• Validate implemented features against defined HMI requirements and produce clear documentation for software structure, workflows, and communication interfaces.
• Support integration testing with existing Phase 1 HMI features and connected hardware modules and converting it to .NET 10 from .NET 8.

Qualifications

• Ongoing Master’s degree in Electronics, Mechatronics, Computer Science, or a related technical field.
• Basic experience with SPS/PLC programming (Siemens TIA Portal, Beckhoff TwinCAT, or equivalent).
• Basic understanding of Databases (SQLite) and communication protocols like OPC UA/ADS.
• Experience with C#, .NET, C++, or similar technologies is a plus.
• Interest in industrial automation, control systems, and human machine interfaces.
• Structured, independent working style with interest in applied industrial research.
• Proficient German and English language skills are required.
