With open automation into the electrified future

Audi uses PLCnext Technology from Phoenix Contact at its Ingolstadt facility in Germany for the body shop of the all-electric Audi Q6 e-tron series. This open ecosystem supports numerous IIoT functions and includes integrated cybersecurity compliant with the IEC 62443-4-2 standard.

Phoenix Contact supports sustainability through key technologies for electrification, networking, and automation. PLCnext Technology, an open ecosystem with numerous interfaces from sensor to cloud, facilitates continuous information flow in carbon-neutral production. It supports standard PLC programming (IEC 61131-3) and high-level languages (C/C++, C#, Matlab Simulink) running in real time on PLCnext Control controllers. This integration benefits both IT and OT specialists, aiding the automation of Audi’s production facilities.

Improving the greenhouse gas balance through optimized production processes

Audi aims for carbon-neutral production at all sites by 2025, a goal already achieved at Ingolstadt in early 2024. In the body shop, improving emission values through quality, availability, and adaptability is crucial. Production-related GHG emissions increase with no-load periods or rejected bodies, raising costs and impacting the GHG balance.

To prevent increased GHG emissions and costs, Audi implements shutdowns during no-load times and uses communication-capable energy meters. These include Phoenix Contact’s EEM-MA 370, to monitor consumption. Transparency in energy flows and early detection of malfunctions are crucial. Ultimately, identifying minor quality deviations early can significantly improve process flow. This in turn results in shorter cycle times and optimized energy balance for each car.

Taking faith out of the leap

A team from ccc software gmbh and the Institute for Applied Training Science in Leipzig has developed a complex analysis system for coaches, athletes, and sports scientists. The system includes a camera or video system and speed measurement. Furthermore, ensuring that recorded data is immediately available for analysis. Ski jumping, a sport with major international events. It is known for its spectacular jumps, with participants reaching speeds of up to 108 kilometers per hour. Moreover, The Audi Arena Oberstdorf in Oberstdorf, Germany, has one of the largest ski jump ramps in the world, with a ramp size of 235 meters and a record of 242.5 meters. The jumping tower is 72 meters high, and the run-up length for jumpers is 118 meters with a run-up inclination of 38.7 degrees. 

A variety of challenges 

The length of a jump is measured from the edge of the jump-off platform to the point of landing. The athlete’s body and ski posture significantly influence the aerodynamics. To optimize jumping performance, ccc software gmbh and the Institute for Applied Training Sciences have developed a sophisticated solution for training optimization and competition management. The camera must be mounted parallel to the jumper and at flight-path height. However, the jumper is only parallel with the camera for a fraction of a second. The IAT, founded in 1992, supports around 1,000 athletes and their coaches from 19 summer and six winter sports. Aiming to identify and tap into Germany’s top athletes’ performance potential.

Compact Ex i isolators for quick and error-free connection in various applications

Green hydrogen (H₂) is emerging as a crucial alternative to fossil fuels like oil, gas, and coal. Chemical plants, refineries, copper smelters, steelworks, and the mobility sector, aim to use it to achieve climate neutrality. Ex i isolators are employed to safeguard systems from explosions.

In 2023, the German government decided to significantly enhance the role of hydrogen in its updated national strategy by 2030. They aim to have 95 to 130 TWh of hydrogen available by then, with demand projected to reach 500 to 600 TWh by 2045. For comparison, Germany consumed around 866 TWh of natural gas in 2022. To meet these targets, the entire hydrogen value chain must be rapidly expanded. From production by electrolyzers from renewable energy to storage, processing, and distribution.

Challenges in the use of hydrogen

Hydrogen’s high energy content and carbon-neutral combustion, producing only water (H₂O), are significant advantages. However, handling H₂ requires caution due to its properties. It is fourteen times lighter than air, leading to rapid evaporation in open-air systems. It also has high diffusivity, allowing it to penetrate other media. Hydrogen is also highly explosive, with a minimum ignition energy of 0.02 mJ, one of the lowest among flammable gases. It belongs to the most dangerous ignition group IIC, along with acetylene and carbon disulfide. It also has a wide explosive range from 4% to 77% by volume in air.

Floating connectors with considerable tolerance compensation and high-speed data transmission

When it comes to board-to-board connectors, there are numerous versions: small and large pitches, low and tall designs, robust and simple connectors. The Finepitch FS 0,635 series connectors with floating properties are a new addition to the Phoenix Contact portfolio. What makes floating board-to-board connectors so special? Where are they used? And are high-speed data transmission and floating a contradiction in terms?

Features of a floating connector

Board-to-board connectors consist of the contacts that establish an electrical connection and a housing that protects and fixes the contacts. While floating connectors have two housing parts connected by contact metals. The inner housing contains the pin connector pattern, while the outer housing protects soldering surfaces and contacts. The floating contacts are long and curved, allowing the inner housing part to move within the limits set by the outer housing. This allows the pin connector pattern to be moved within a large tolerance range while the soldering area remains fixed. The FS 0,635 series allows a tolerance of 0.6 mm in the plug-in direction, known as wiping. The FS 0,635 floating female connector strip can be combined with three male connector strips to create different stack heights.
