Robert Brandl
Last position:
Team Lead; Software Developer at Provider of industrial control systems for manufacturing and digital transformation
Industrial Communication | Proof of Concept: Controller-to-Controller Communication with OPC UA FX
Proof of Concept for OPC UA FX-based controller-to-controller communication between virtual programmable logic controllers (vPLC) on an industrial edge platform. A virtual test environment was set up on Debian Linux in two phases (including VMs and vPLCs), shared-memory communication (real-time information bus) was activated, and the RIB solution was integrated into a customized product firmware (including shared memory and PROFINET support) and deployed in containerized environments (Docker). Additionally, a virtual Ethernet connection was developed to simulate the network topology. Finally, commissioning, functional tests, sample application creation, comprehensive documentation, and customer support were completed.

About the technology
What SiL does
Software-in-the-Loop, often called SiL, tests software inside a simulation instead of on target hardware. It helps teams check control logic, edge cases, timing, and integration early. That makes it useful for embedded systems, automotive functions, robotics, and other software that must behave predictably.
Where it fits
- Validate control software before hardware is ready
- Reproduce rare faults and boundary cases in a safe setup
- Compare software behavior against model expectations
- Support regression testing after each change
SiL is often part of a wider V-model, next to model-in-the-loop and hardware-in-the-loop work.
Tooling and models
Strong professionals working with Software-in-the-Loop know how to connect code, plant models, test frameworks, and simulation tools. They may work with MATLAB/Simulink, FMI/FMU setups, Python test scripts, C and C++, or AUTOSAR-related stacks, depending on the system. The key is clean interfaces, repeatable runs, and traceable test results.
When companies bring help
Companies usually look for freelance expertise when a release is blocked by test setup gaps, when a simulation must mirror real behavior more closely, or when a team needs extra hands for validation work. In Germany, this is common in automotive supply chains, industrial automation, and other engineering-heavy environments where software must be tested early and documented clearly.
What strong experts do
- Define test cases that reflect real operating conditions
- Tune simulation parameters and inputs
- Find mismatches between model and code behavior
- Write clear results for engineering and quality teams
Good specialists do not just run tests. They question assumptions, isolate failures, and explain what the results mean for the next build.
How projects stay on track
SiL work needs close cooperation between software, simulation, and validation people. Remote work is common for test development and analysis, while on-site time can help when systems, models, or team processes are tightly coupled. The best results come from experts who can work with technical detail and keep the test flow disciplined.
Frequently asked questions
The facts hiring teams ask for most often when it comes to Software-in-the-Loop.
Software-in-the-Loop is used to test embedded or control software in a simulated environment before it runs on real hardware. It helps teams verify logic, interfaces, timing, and fault handling early. That reduces surprises later in integration and validation.
SiL is related to both, but it is not the same. Model-in-the-loop checks behavior at the model level, while Hardware-in-the-Loop includes real hardware in the test loop. SiL sits between them and focuses on the compiled or source software running against simulation inputs.
A strong Software-in-the-Loop specialist usually knows simulation setups, test automation, and the software stack being verified. Common adjacent skills include MATLAB/Simulink, FMI/FMU handling, C or C++, Python, and model-based testing. They should also be comfortable reading requirements and turning them into testable cases.
Software-in-the-Loop is common in automotive functions, industrial control, robotics, and other embedded systems. It is especially useful when software must be validated before a prototype exists or when repeated regression testing is needed. Any project with complex logic and safety or quality concerns can benefit.
SiL work can start with a specialist who understands simulation and test basics, but complex programs need deeper domain knowledge. If the project involves timing behavior, system models, or strict traceability, look for someone who has handled similar validation work before. The more critical the software, the more important that experience becomes.
Yes, Software-in-the-Loop is often well suited to remote work because most tasks involve code, models, and test data. On-site time can still help when the team needs access to protected systems, hardware context, or close workshop-style collaboration. For many German engineering teams, a hybrid setup is practical.
A good Software-in-the-Loop freelancer writes repeatable tests, explains assumptions, and connects results back to requirements. Look for clear thinking around simulation boundaries, failure cases, and traceability. Strong output is not just a passing test run, but a setup your team can trust and reuse.
Ask the Software-in-the-Loop specialist which simulation tools they have used, how they handle interfaces, and how they document test results. Also ask how they would validate the model, detect mismatches, and integrate the work into your release process. Those answers show whether they can support your actual workflow, not just run tests.
