Siemens and Audi enable virtual shop floor automation

Audi has also implemented AI-driven automation for optical inspection based on the Siemens portfolio. The goal is to automate detection and removal of weld spatter on vehicle bodies using a customer-trained AI algorithm and high-resolution images. As a result, Audi has realised a higher car body quality and more efficient manufacturing processes.

Audi is using Siemens’ automation portfolio to standardise and optimise its shop floor operations, creating a more agile, flexible, and safe production environment. To speed up the transition from automated to highly adaptable production, the IT and OT levels are merged by successively virtualising the shop floor. As software-defined factory automation is only feasible with a corresponding controller solution, Audi is using the Simatic S7-1500V – Siemens’ first entirely virtual controller – for their car body assembly line at Audi’s Böllinger Höfe factory in Neckarsulm, Germany. The automotive manufacturer has started integrating the virtual programmable logic controllers (PLCs), which are compatible with Audi’s cloud infrastructure platform Edge Cloud 4 Production. Audi is planning to roll out the virtual PLCs in their body shop at the Neckarsulm factory this year.

“A virtualised shop floor is a key enabler for a flexible production,” said Gerd Walker, AUDI AG board member for production and logistics. “Siemens’ software-defined automation portfolio empowers us to rapidly respond to market changes and optimise our manufacturing for more efficiency and flexibility.”

“Controllers are the ‘brains’ of machines and factories. Now we are virtualising these brains and bringing them to the cloud. This accelerates Audi’s digital transformation and increases agility, efficiency, and safety in production – for more flexible, future-proof manufacturing. Together, we’re taking automotive production to a new level and significantly strengthening competitiveness," said Cedrik Neike, CEO of digital industries and member of the managing board of Siemens AG.

The Simatic S7-1500V, part of the Siemens Xcelerator portfolio, is designed to integrate IT and software capabilities in the automation world. As a hardware-independent solution, this virtual controller provides the same functionalities as a Siemens hardware controller. It’s fully compatible with Siemens’ Totally Integrated Automation (TIA) portfolio and can be engineered via TIA Portal. Users gain access to all the functions, interfaces, and tools they’re familiar with from previous hardware PLC use. The controller is available via Industrial Edge, and it can be directly integrated into the IT infrastructure. This allows Audi to centrally manage the virtual PLC and adapt it flexibly to meet specific needs. This makes PLC projects easier to scale, and open data interfaces mean they can be readily combined with other IT offerings.Siemens and Audi are enabling virtual shop floor automation.

Siemens has reached another milestone with the TÜV safety certification for its virtual PLC: The Simatic S7-1500V F is the first fail-safe virtual controller on the market. Implementing robust fail-safe functionalities in automation technologies is critical to safeguarding production workers and ensuring reliable machine operation. In the past, fail-safe components have required specialised hardware to provide the necessary functional safety. With the fail-safe virtual PLC, Siemens has now implemented safety mechanisms in an industrial edge environment. These advanced safety features allow users to migrate safety-sensitive applications to software-defined automation environments.

Siemens has supplied Audi with the infrastructure to deploy and manage an AI-driven system for real-time quality control in car body construction, which has helped Audi make their production processes AI-ready. By utilising the Siemens Industrial AI Suite and the Simatic industrial PC BX-59A as an edge device, the solution enables Audi to conduct complex AI-based quality inspections, meeting the requirements for automated removal of weld spatters. Consequently, Audi is significantly increasing its production rates and improving occupational safety.
