Architecture and programming for an automotive test bench platform at Automotive supplier
In this project, I was responsible for designing and implementing 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 UML modeling used consistently throughout. This structured approach significantly increased the reusability of individual LabVIEW test modules and sustainably reduced development time for subsequent projects. I also integrated modern automotive standards such as CAN FD, LIN, and safety requirements, making the solution future-proof.

About the technology
TwinCAT in automation
TwinCAT is Beckhoff’s software-based automation suite for controlling machines, production lines and connected equipment from industrial PCs. It combines PLC programming, motion control, safety, visualization, measurement and communication in one engineering environment. TwinCAT 3 supports modular control architectures built around IEC 61131-3 languages and real-time execution.
Control and motion
TwinCAT projects can coordinate servo drives, robots, conveyors, packaging stations and process equipment. Specialists configure deterministic tasks, axis groups, cam profiles, safety functions and machine states while connecting field devices through EtherCAT. They also create reusable function blocks, libraries and diagnostics that make complex machinery easier to operate and maintain.
Ecosystem and tooling
- Program PLC logic with Structured Text, Ladder Logic and function blocks
- Configure EtherCAT networks, I/O terminals and Beckhoff IPCs
- Implement TwinCAT HMI, OPC UA and database connections
- Integrate TwinSAFE, servo systems, vision and third-party equipment
The wider Beckhoff ecosystem includes TwinCAT HMI, TwinCAT Analytics, TwinCAT Machine Learning and engineering tools for deployment, testing and version control. ADS enables communication between TwinCAT components and external applications, while OPC UA supports broader industrial data exchange.
When companies need specialists
Companies bring in freelance TwinCAT professionals when a machine launch is approaching, an existing control system needs modernization or internal capacity is limited. Typical work includes PLC migration, motion tuning, EtherCAT commissioning, HMI redesign, safety implementation and troubleshooting of intermittent real-time issues. In Germany, collaboration may combine remote programming with on-site commissioning at a plant or machine builder.
What strong professionals deliver
Strong TwinCAT experts understand both software structure and physical machine behavior. They define clear state models, separate reusable logic from application code and document I/O, alarms, parameters and recovery paths. They test changes against realistic sequences, protect safety boundaries and leave teams with maintainable projects rather than isolated fixes.
Selecting the right fit
Look for professionals whose past work matches the machine type, drive technology and required communication standards. Ask how they approach version control, simulation, commissioning and fault analysis, not only which TwinCAT features they know. German language skills can help with plant teams and documentation, while remote work is effective for code reviews, architecture and prepared commissioning tasks when site access is available.
Frequently asked questions
Quick answers to the questions that come up most around TwinCAT.
TwinCAT is used to program and run industrial control systems on Beckhoff industrial PCs. Companies use it for PLC logic, motion control, robotics, safety, HMI, measurement and data integration across machines and production lines.
TwinCAT runs automation functions on PC-based control hardware and brings PLC, motion, HMI and analytics into a connected software environment. It is often weighed against proprietary PLC ecosystems from Siemens, Rockwell Automation or Schneider Electric, with the best choice depending on hardware strategy, engineering skills and integration needs.
A strong TwinCAT specialist often understands EtherCAT, Beckhoff IPCs, servo drives, TwinSAFE, OPC UA and industrial networking. Knowledge of machine design, electrical schematics, HMI usability and commissioning is also valuable because control software must work with the complete machine.
TwinCAT work can range from a focused PLC change to a complete machine control system, so the required background depends on scope and risk. A small software task may need targeted platform knowledge, while motion, safety or production commissioning calls for a professional who has handled comparable equipment through testing and start-up.
TwinCAT programming, code reviews, HMI work and much of the testing can often be completed remotely from Germany. On-site access may still be needed for electrical checks, drive tuning, network faults, safety validation or final commissioning, so agree early on which phases require presence at the plant.
TwinCAT projects should be aligned with the target runtime, engineering environment, libraries and Beckhoff hardware before work begins. A specialist should check project compatibility, package dependencies, source control and the upgrade path rather than assuming that a newer environment can be deployed without validation.
Review whether TwinCAT code has clear task design, naming, state handling, diagnostics and recovery behavior. Ask for evidence of structured testing, documented interfaces and safe commissioning practices, then use a technical review or pilot change to assess how the professional reasons about the machine.
TwinCAT projects appeal to freelancers who enjoy combining software with real machines, deterministic control and industrial communication. The work can span PLC architecture, motion, HMI, safety and data systems, making it a fit for professionals who want responsibility across the automation stack.
The average hourly rate of freelancers in Germany who have used TwinCAT in their recent projects is 94 €, which corresponds to a daily rate of about 752 € based on an 8-hour working day.
