Examples from software development

• Control software for plant controllers
• Firmware for microcontrollers
• 3D visualizations and simulations
• Terminals for RS232, CAN, UDP, Ethernet
• Libraries for control engineering
• Spectrum analysis of arbitrary signals
• Software for CAD automation
• Function block editors

Depending on the requirement, we use Microsoft Visual Studio with the programming languages C# or VB.NET, or for low-level hardware programming AVR Studio with C++.

Control software of an industrial plant whose process data are matched in real time with a simulation or digital twin. The visualization was implemented with DirectX-3D.

Plant control that can wrap arbitrary rotational bodies with packaging tape. The software scans the rotational body three-dimensionally before wrapping and calculates the optimal wrapping scheme based on predefined rules.

Fully automatic CAD software that generates 3D models, quotations, data sheets, and production drawings from product data of an ERP system.

Audit-proof document management software with user rights management and direct display of Word and PDF files within the program.

Display of ICE and regional trains on an Open Maps map. Current data for each train can be retrieved from a database.

Software that enables configuring, testing, and uploading firmware via RS232 and LAN at a manufacturer of radio modules.

Software for monitoring and visualizing process data output by a PLC controller for debugging.

Training software for control loops, allowing process plants to be connected via RS232. Many function blocks such as PID controllers or DT1 elements are available. The control loop can be modified during runtime. Signal control deviations are displayed in red.

Signal analysis that visualizes audio signals fed in via the microphone. Recurring tones or rhythms are detected and displayed using FFT and mathematical convolution.

Disc jockey software that suggests suitable songs based on the currently playing track. The track ranking takes into account analyzed tempo, genre, key, and presence in playlists. The software learns from each DJ gig and improves the algorithm.

A software library for automation and control applications with C# or VB.NET. The library makes it possible to implement, e.g., PIDT1 controllers, time elements, and signal generators with just one line of code.

Test environment that allows the behavior of digital controllers to be easily tested. The screen recording shows how a T2S control element reacts to fluctuating cycle times. The comparison shows the difference between Euler forward, Euler backward, and Tustin methods.
