Architecture and Programming for Automotive Test Bench Platform at Automotive Supplier
In this project, I was responsible for the design and implementation of a new, modular, and highly scalable test bench platform for an automotive supplier. My focus was on developing a robust system architecture and programming the associated software, with consistent use of UML modeling throughout. This structured approach made it possible to greatly increase the reusability of individual LabVIEW test modules and to significantly reduce development time for follow-up projects. I also integrated modern automotive standards such as CAN FD, LIN, and safety requirements, which made the solution future-proof.

About the technology
TwinCAT in practice
TwinCAT is Beckhoff’s automation software for industrial control. It turns an IPC into a real-time PLC, motion, and engineering platform for machines, lines, and test rigs. Teams use it to build control logic, fieldbus connections, HMI links, and data flows between shop floor and higher-level systems.
What it covers
- PLC programming for machine and line control
- Motion control for axes, drives, and synchronized movements
- EtherCAT-based device integration and diagnostics
- HMI, SCADA, and data exchange with plant systems
- Commissioning support for new machines and retrofits
Ecosystem and tools
TwinCAT is usually paired with Beckhoff IPCs, EtherCAT devices, and Windows-based engineering environments. Strong specialists work with TwinCAT 2 or TwinCAT 3, structured text, function blocks, and version control around control projects. They also understand safety, alarms, signals, and how code behaves on real hardware.
When companies bring in experts
Companies look for freelance TwinCAT specialists when a machine launch is blocked, a control concept needs cleanup, or an existing installation must be extended. This is common in factory automation, packaging, intralogistics, test equipment, and process lines in Germany, where on-site commissioning and remote debugging often need to be combined.
What strong specialists deliver
Strong professionals do more than write code. They read electrical drawings, trace fieldbus issues, tune motion behavior, and document changes clearly for later service work.
- Stable PLC structures that other specialists can maintain
- Clean I/O mapping and device handling
- Reliable startup, alarm, and fault recovery logic
- Clear handover notes for operations and service teams
Choosing the right fit
For smaller changes, a focused TwinCAT expert may be enough. For larger projects, look for someone who has worked across control cabinets, drives, sensors, and real commissioning work. The best fit speaks the language of machine builders and plant teams, and can work in German or English depending on the site.
Frequently asked questions
Quick answers to the questions that come up most around TwinCAT.
TwinCAT is used to build control software for machines, production lines, test systems, and other automation setups. It combines PLC logic, motion control, fieldbus communication, and engineering tools in one environment. Many teams choose it for Beckhoff-based systems where real-time control matters.
Yes. TwinCAT is the product name used for Beckhoff’s automation software, so searchers often say Beckhoff TwinCAT as well. In practice, both terms point to the same ecosystem of PLC, motion, and EtherCAT tooling.
TwinCAT is often chosen when a project is built around Beckhoff hardware, EtherCAT, or tight PC-based control. Compared with Siemens TIA Portal, it fits a different hardware and engineering ecosystem. Compared with CODESYS, it is more closely tied to Beckhoff’s real-time automation stack and tooling.
A strong TwinCAT specialist usually understands PLC programming, real-time debugging, industrial networks, and basic electrical documentation. For motion-heavy projects, knowledge of servo drives, axis tuning, and synchronization is important. For factory systems, HMI and data exchange skills also help.
A good TwinCAT freelancer can start with a clear machine or line description, I/O lists, drive details, and any existing code base. The more complex the commissioning, the more useful it is to share wiring diagrams, fault logs, and current PLC structure. This keeps early work focused and avoids delays on site.
TwinCAT work is often a mix of both. Coding, review, and diagnostics can usually be handled remotely, but commissioning and hardware faults often need on-site time at the machine or plant in Germany. The best setup is the one that matches the phase of the project.
Look for proof of real machine or plant work with TwinCAT, not just general software skills. Ask about Beckhoff hardware, EtherCAT diagnostics, motion tasks, and how the specialist handles commissioning and handover. Clear examples of troubleshooting and documentation are a strong sign of quality.
A TwinCAT specialist will usually want to know the hardware stack, project phase, access to the source code, and whether the work includes commissioning or only software changes. They also need to know if they can work remote, on site, or both. This helps them judge whether the assignment is a good fit.
The average hourly rate of freelancers in Germany who have used TwinCAT in their recent projects is 96 €, which corresponds to a daily rate of about 769 € based on an 8-hour working day.
