Cibano 500 Testing Interface

The Cibano 500 Testing Interface is a custom-built, web-based software solution designed to overcome the limitations of the existing Omicron software by enabling unlimited circuit breaker test sequences.

Cibano 500 testing interface overview

Initial Situation

Developing a new circuit breaker requires strict compliance with industry standards and extensive testing to ensure safety, reliability and performance. Each device must undergo a large number of test sequences before it can be approved for use. However, the software currently used to control the testing process imposes a limitation on how many tests can be executed consecutively. This limitation reduces testing efficiency, especially during long-running automated test scenarios where continuous execution and reliable monitoring are essential.

Project Goal

The goal of the project is to allow engineers at Pfiffner to run an unlimited number of test sequences using the Cibano 500 while still capturing all relevant measurement data. The main idea is to remove the limitations of the existing Omicron Test Manager software and give users more control over how tests are executed. At the same time, the core features and familiar workflow of the original application remain available, allowing seamless integration into the current testing process. On top of that, small improvements such as a clearer interface, easier test configuration and better visualization of results help make everyday work more efficient.

Test Selection and Management
                            
In the test selection and management interface, test sequences can be organized into groups, scheduled and monitored throughout execution.
Test Configuration Detail
                            
In the detailed test configuration view, timing parameters and technical settings can be adjusted to customize the behavior of individual test sequences.
Measurement Data Visualization
                            
In the measurement data visualization interface, recorded test values are displayed graphically to support real-time monitoring and analysis.

Developed Solution and its benefit

To achieve the project goal, a custom application was developed that interacts with the Cibano 500 API by repeatedly sending requests to execute test sequences defined in the UI. After each test, the results are automatically collected, stored and visualized in real time, ensuring continuous feedback and full transparency during execution.

The solution offers several benefits:

Intuitive and user-friendly UI designed for engineers familiar with the Omicron Test Manager.
Importing, editing and reusing existing Omicron test files without changing established workflows.
Live updates and clear visualization of test results after each execution step.
Removal of the built-in limitation, enabling an unlimited number of test sequences.
Reduced manual effort through automation and improved overall testing efficiency.

Testimonial
«Working with the student team was an enriching experience. Their dedication and adaptability were particularly evident in their ability to take on additional and modified goals as the project progressed. Their commitment and problem-solving approaches led to results that met and, in some cases, exceeded our expectations. The collaboration was smooth and professional; we would like to thank them for their efforts and look forward to our next project with the FHNW.»
